BILZ Precision Leveling Wedges are manufactured in three different models; free standing (PK Series), bolt-on to the machine (PKA eries), bolt-through to the floor, foundation (PKD Series). This design permits the highest precision leveling range, to within 0.0004" (0.01mm). Our self-locking design prevents creep from the installed position. Large support surfaces provide optimum foundation support and rigidity. Any of the BILZ Isolation materials can be bonded to the and/or bottom of the leveling wedge to provide the required vibration isolation.Machine leveling with Bilz leveling wedges is very fast and efficient, especially when compared to other machine levelers or leveling feet. The full weight of the machine can be applied directly to the leveling wedge and the leveling wedge can be adjusted to level the machine. This allows you to reduce the time needed for rented equipment such as portable cranes and fork lifts. Once the machine is set onto the leveling wedges, initial adjustments of the leveling wedges can be carried out with a torque wrench to assure that equal loading is applied to each leveling wedge. A precision machinist level can then be used to finely adjust each leveling wedge to accurately level themachine to within 0.0004" (0.01mm).
