TOLERANCE DETAILS

Housing – Ø

Bushing after mounting

Depends on diameter. Please note, that fitting tolerances have to be "plastic-tailored" considering the larger expansion coefficient compared to metal sliding bearings. Therefore bigger fitting tolerances occur (to be advised by LHG).

Shaft tolerance

Depending on application

SHAFT MATERIAL

Steel >200HB dressed to size, surface roughness ≤ Rz 4

MOUNTING ADVISE

Housing – Ø

Mounting bevel, min. 1,5 mm x 15-45°

Shaft

Mounting bevel, 5 mm x 15°, edges rounded

Force fitting mandrel

The use of an adequate force fitting mandrel is advisable.

MAINTENANCE

No maintenance necessary. COM-KU®/D is a maintenance-free plastic sliding bearing. If non-stainless shafts are used, lubrication against shaft corrosion necessary!

On request further materials are available for higher demands, e.g. for higher temperature ranges.

The above stated material properties are valid for optimal operating conditions. Through changes of the application conditions e.g. higher sliding speed or strain, these values are subject to change.
