Using a unique metal material with high strength and excellent abrasion resistance, it features secure performance and long life while remaining thin.
Part Number
Configured Part Number is shown.


Direction of movement / mating shaft [d8: general use (heavy load), e7: general use (light load), f7: for high accuracy] / bushing / housing
A reliable long lifespan bearing that combines compact design and durability
Application range (SP5SL1)
| Lubrication conditions | No lubrication | Regular lubrication |
|---|---|---|
| Operating temperature range°C | -40 to +150 | |
| Maximum allowable surface pressure P N/mm2 [kgf/cm2] | 49 (170) [500 (1,735)] | |
| Maximum allowable speed V m/s (m/min) | 0.25 (15) | 0.50 (30) |
| Maximum allowable PV value N/mm2·m/s {kgf/cm2·m/min} | 1.65 {1,010} | 3.25 {1,990} |
The value in parentheses is static allowable surface pressure: This indicates the allowable surface pressure when there is no sliding or when sliding at an extremely low speed of 0.0017 m/s, "0.1 m/min," or less.
*The above figures are for when SL1 is used as the solid lubricant.
Mechanical Properties
| Density (g/cm3) | 7.8 |
|---|---|
| Tensile strength JIS Z 2241 N/mm2[kgf/mm2] | 785 {80} |
| Tensile elongation at break JIS Z 2241 (%) | 10 |
| Compression strength N/mm2[kgf/mm2] | 392 {40} (Note 1) |
| Hardness JIS Z 2243 (HBW) | 235 |
| Young's modulus N/mm2[kgf/mm2] | 98,000 {10,000} |
| Linear expansion coefficient (×10-5°C-1) | 2.13 |
* The values in the table are representative values, not standard values.
(*1) Compression strength 0.1%

*The inner diameter tolerance after press-fitting is a reference value when press-fitted into the housing (H7).
When solid lubricant SL401 or 403 is used, it is not lead-free.
