KS PERMAGLIDE® plain bearings: Bearing in movable workpiece table

Sector: Engineering

Product used:


Movable tables are used for equipping hydraulic presses. They enable the machine to be loaded and unloaded quickly. The movable table consists of a workpiece holder mounted on a table. For loading, the table is pulled out and pushed back into the machine with the workpiece once mounted.

Requirements for the bearings in movable tables

  • A slight plain bearing clearance is required in order to guide the work table precisely and without canting. The slight plain bearing clearance means that a large portion of the stress from the pressing process is transferred to the frame via the plain bearings.
  • In order to pull it out and push it in easily, the table must run smoothly in the guide for the long-term. 
  • The machine must withstand long periods of use with low maintenance requirements. 
  • To prevent the table from becoming too big, plain bearings with small dimensions are required.
  • The costs for production and mounting should be as low as possible.

Press with movable workpiece table

Bearing with KS PERMAGLIDE® P11 plain bearing strips

The bearings on the movable workpiece table of the press have been made with multiple maintenance-free plain bearing strips in the material KS PERMAGLIDE® P11. The strips were screwed into the recess of the table frame. This ensures that the table is guided by the P11 strips at the side, above and below the table.
