Properties and characteristics
The following table gives general tendencies and experience values. Because of the complexity of the involved processes deviation may occur in the concrete application case.
- SL: sintered sleeve bearings
- KL: ball bearings
criteria, characteristics |
sintered sleeve bearings (SL)
|
ball bearings (KL)
|
|---|---|---|
| continuous operation | suited for higher speeds (>ca. 500 min-1) | suited for all speeds |
| start-stop operation | reduced life expectancy |
suited |
| reversed operation | not suited | suited |
| atmosphere (humidity, inert gases, vacuum) | not suited for vacuum |
not problematic, if necessary special lubrication |
| high ambient temperature | up to 85°C not problematic | |
| low ambient temperature | less suited (if necessary special lubrication) | |
| noise | quieter | louder |
| price | lower | higher |
Application fields
Sintered sleeve bearings
- in smaller motors
- for continuous operation at higher speeds
- in spur gearheads
Ball bearings
- in bigger motors
- for continuous operation at high and low speeds
- for start-stop-operation, reversed operation
- in planetary gearheads
