Precision levelling wedge PKA

PKA – Precision levelling wedge, bolt-on

Bolt-on Bilz precision levelling wedges PKA are used on machines subject to high thrust that require a permanent connection to the machine bed, such as injection moulding machines, slotting machines, extrusion machines etc.

The bolt-on levelling wedges remain in position even when the machine is lifted, significantly easing the installation of the machine.

All information on our levelling wedges can be found in our catalog excerpt “Precision levelling wedges” (PDF).

Note

The specified maximum load is composed of static and dynamic loading of the machine. The best insulation effect is achieved at approximately 80-90 % of the specified maximum load.
Permissible temperature range: -20 °C to +80 °C
Colour: RAL 7037, dusty grey
The type of insulation pads used can be found in the type designation, for example PKA 3-0 is equipped with pad B0.
Please contact us if the size, insulation pad mounting or bolt size that you are looking for is not listed. In addition to our standard solutions and colours we also carry numerous special solutions. We are always happy to give advice.
