TECHNICAL DATA COM-KU®/D

Fibre reinforced plastic composite sliding bearing
Maintenance-free
Cylindrical and flanged bushings are standard fabrication.
All special designs are available at short notice!

PROPERTIES	Good sliding properties, suitable for high load capacity (as well as impact load and edge pressing), very good at low sliding speeds, good chemical resistance, long length of life, suitable for reparation of lubricated bushings, good damping features. Maintenance-free!
MATERIALS	Compound plastic, winding technique*
MATERIAL PROPERTIES **
Specific load capacity static	≤ 325 [ N/mm² ] dep. on temperature and length of strain
Specific load capacity dynamic	≤ 95 [ N/mm² ] dep. on temperature and sliding speed
Sliding speed	< 2,0 [ m/s ]
Friction value	0,04 till 0,1 [ µ ]
Temperature strain	-160 - +130 [ C° ]
Max. Pv - value	0,4 - 2,0 [ N/mm² x m/s ]
Moisture absorption	0,15 [ % at 20°C in 24h ]
TOLERANCE DETAILS
Housing – Ø	H7
Bushing after mounting	Depends on diameter. Please note, that fitting dimensions and tolerances have to be "plastic-tailored" considering the larger expansion coefficient compared to metal sliding bearings. As a result larger tolerances ranges and clearance fits can occur.
Shaft tolerance	Depends 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 application of an adequate force fitting mandrel is advisable.
MAINTENANCE	No maintenance necessary. COM-KU®/D is a maintenance-free plastic sliding bearing.
*	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.
