The MECH V-RING is a unique all-rubber seal for rotary shafts. The V-Ring provides a perfect solution to prevent the ingress of dirt, dust, water or combinations of these media while positively retaining grease. With its unique design and performance the V-Ring protects a wide range of bearing types. It can also be used as a secondary seal to protect primary seals that do not perform well in hostile environments. It has been used successfully by OEM and the replacement market world wide in a broad range of applications.

Selection of Rubber

When selecting the correct material i.e. type of rubber compound it is necessary to take the following requirements into account;

• good chemical resistance
• good resistance to high and low temperatures
• good resistance to ozone and weathering
• It is also necessary to consider the need for the following attributes;
• high resistance to wear
• low friction
• low compression set
• good elasticity

Properties

Pressure Range: up to .5 MPa (74 psi)
Temperature: -40 to +200ºC (-40 to +392ºF)
Velocity: 30 m/s (100 ft/s)

Application

The V-Ring is normally long-drawn-out and mounted directly on the shaft, where it is positioned by the inherent tension of the rubber body. It rotates with the shaft and seals axially against a stationary counter face, at right angles to the shaft. The counter face can be the end face of a bearing or a washer, stamping, bearing housing, or even the metal case of oil seal. The sealing lip is flexible and applies only a relatively light contact pressure against the counter-face and yet is still sufficient to maintain the sealing function. The low contact pressure (that varies with the fitted width) allows the seal to run dry in many applications.

Due to the centrifugal force, the contact pressure of the lip decreases with increased speed. This means that frictional losses and heat are kept to a minimum, resulting in excellent wear characteristics and extended seal life. Once breakaway torque is overcome, the power losses reduce steadily until around the 10 -15 m/s band when they reduce quite quickly. In the 15 – 20 m/s band the losses reduce to zero and the V-Ring then serves as clearance seal and deflector.

The flexible lip and hinge allow the V-Ring to function even in the presence of a certain amount of run-out, eccentricity and shaft misalignment. Contact our local company for advice on these and other application issues.

V-Rings are made entirely of rubber without fabric or sheet metal reinforcement. They are, therefore, particularly easy to install. V-Rings can be stretched and, depending on size, installed over flanges, pulleys and bearing housings without costly dismantling.

V-Rings are available in various standard cross-sections to meet various space and application requirements.

• Conveyor of high pressure or high vacuum substances
• To absorb movements
• To absorb vibrations (anti vibrations)
• Noise absorption
• Earthquake movements
• Shock absorption
• VERY HARD 90-100°

This typical joints are made as bellows of stainless steels, PTFE, Hi modulus plastics, glass fibre fabrics (we have separate section), or specialised synthetic elastomers (rubbers). A bellows are designed with single or multiple convolutions depending on length and application, with the shape of the convolution designed to withstand the internal pressures of the pipe, and to ensure flexible enough to absorb lateral , axial, and angular deflections. The higher flexibility with zero leakage are also made with multiple layers. The rubber bellows are manufactured with steel wire & high strength fibre reinforcement. The flanges are made up according to standards or non-standards provided by customers. They are made in different shapes like round, Oval, Elliptical, Conical, rectangle or octagonal.

Pressure balanced expansion joints (bellows)

We have manufactured Expansion joints mainly for industrial piping systems to adapt movement or vibrations due to thermal and mechanical changes in the production line.And some of the process has wider changes in temperature hence metal components vary in size. Expansion joints with metal bellows are designed to absorb certain movements and minimize the conveying of forces to delicate components in the system.

In some of the application pumps built pressure or gravity is used to move fluids through the piping system. Fluids under pressure follow the volume of their vessels.So we designed the unique concept of pressure balanced expansion joints to maintain a constant volume by having balancing bellows compensate for volume changes in the bellows (line bellows) which is moved by the pipe.

Rubber expansion Joint bellows

Wrapping steel wire and fabric reinforced rubber masticated sheets

Rubber expansion joints are primarily manufactured by labour-intensive wrapping of rubber masticated sheets and fabric reinforced rubber sheets around a bellow-shaped product mandrel tool.Along with rubber and fabric, reinforced rubber and/or also steel wires or metal rings are inserted for additional reinforcement. This can be made high pressure resistant. After the entire product is build up on the mandrel, it is enclosed with a winding of (nylon) peel ply to coerce all layers together before pressurization and vulcanization. Because of the labor-intensive production process, it takes longer.

Moulded rubber expansion joints

Rubber expansion joints (some types only) can also be made with a moulding process. They are of medium sized expansion joints with bead rings, which are manufactured in large quantities on a cylindrical mandrel, which is wrapped with partiality cut fabric ply. This part is finally placed in a mould and moulded into shape and vulcanized. We manufacture for automobile sector for their bulk and faster needs.

Our next project is to adopt new technology for robotic manufacturing of Automated winding of rubber expansion joints.

Stainless Steel Plated Bellows

Stainless steel bellows protect against welding splatter hot chips, and heavy chip loading. It is designed for hostile and/or extreme environments. Spring-loaded steel plates are mounted to every fold of conventional bellows, on one side or multiple sides. The steel plates push the debris off of the adjoining steel plate avoiding debris from contacting the bellows beneath. Horizontal applications work best with fixed plates and vertical applications are optimized with the hinged plate design.

Stitched Bellows

Mech Spares designed stitched bellows for severe environments. They can handle extreme temperatures, high abrasion and tight compression applications. Mech Spares uses the best chemically treated thread for the highest level of performance, Stitched bellows can be combined with rigid PVC reinforcement. They are economical solution, but it has limitation of not being liquid proof. It’s a labour intensive design.

Polygonal Laminate Bellows

Polygonal laminate bellows are aesthetically proven designs because they are available in almost any shape, and further they are attractive and practical bellows made in horizontal and vertical systems. The bellow material selection can be matched with different interior materials, and their divisional design allows for easy replacement in the case of impaired sections. It can be enhanced with, gliders and /or rigid PVC reinforce. Polygonal laminate bellows can operate in ambient temperature and humidity conditions.

Disk Rubber Bellows

This bellows are of high quality protective covers for pistons and spindles. The rubber disks are pressed out and vulcanized for added toughness and elasticity. They can be used for most regular and external applications. We recommend Nitrile & EPDM rubber covers for oil or coolant protection. We suggest alternative material for high temperature applications. They are robust in nature.

Moulded Bellows

We use moulding process to produce a wide variety of shapes and sizes. Moulded bellows are designed to resist alkalis, acids, dust and water. They are produced in large quantities.

Flange Sealing Technology Through Gaskets

Our work at the frontier of sealing technology gives us a clear understanding of the roles that gaskets must play, for example:

• If joint faces are absolutely flat and aligned true.
• If flanges do not distort under load.
• If loaded bolts do not stretch or relax…

…There is no need for a gasket, because the joint will be perfect.

In the real world, such perfection is very expensive to achieve and almost impossible to maintain. Therefore a gasket is the most practical and cost effective way to seal a bolted flange joint.

Our knowledge and experience will resolove the major problem of designers and maintenance engineers to to select the correct gaskets to ensure the integrity and safeoperation of their fluid handling plant.

We at MECH begin our journey as Polyurethane suppliers and turned to biggest Polyurethane Manufacturers in India to PU products designers. We did recognised that Unlike any other engineering material, Cast Polyurethanes itself have an extraordinary combination of physical, mechanical, and environmental properties.

The proportion between the resin and the curative agents can be varied to optimize some of these properties (sometimes it affects other properties). So, a proper combination will help to engineer the compound to achieve desired properties.

In most applications Polyurethane products offer following advantages.

• Resilience (high or low )
• Additional Toughness leads to Durability
• load bearing capabilities
• High Resistance to Tear and Cut
• Low Compression Set
• Impact resistance
• Outstanding Abrasion resistance
• Machinability to desired shape
• Oil, solvent, water and ozone resistance.
• Flex fatigue resistance
• Good Electrical properties
• Friction (high or low) Mechanical Properties
