Material

Sizes NK 1 and 2 = Steel
Sizes NK 3, 6 and 9 = Cast-iron

Standard model

Type NK frictionless tables consist of equal length upper and lower sections and type R linear bearings. All tables are equipped with type AC roller cages and type GB endpieces and can be mounted vertically or horizontally. The lower section includes standardized attaching holes. The sides opposite to the setscrews in the upper and lower sections can be used for mounting purposes. For the standard model stroke limiting is made by means of two screws in the upper section and one screw in the lower section. These screws can withstand only small forces or impacts in the direction of motion and should not be used as stops. With FORMULA-S these screws are no more necessary due to the cage assist system.

Special models

Standard attaching holes (–B)
In the upper section (other hole configurations on request)

Roller cages type EE (–EE)
Plastic material, only available for sizes 6 and 9. Provides sealing against dirt and dust; therefore somewhat stiffer motion

Ball cages type AK (–AK)
For reduced sensitivity to dirt. Lower load carrying capacity

Cage assist integrated (–KS)
For high dynamics and all assembly orientations for sizes 3 and 6
