|
| Note: Friction coefficient μ |
Friction coefficients of unsealed linear bushings when lubricated with oil. The friction coefficient is lowest under heavy load, but can still be above the specified value even under a low load.
|
| Note: Friction force FR |
One wiper seal: Multiply value with factor 0.5
|
| Note: Maximum dynamic load capacity Cmax |
The dynamic load capacities are based on a total travel of 100,000 m. When based on 50,000 m, the C values in the table are to be multiplied by 1.26.
|
| Note: Minimum dynamic load capacity Cmin |
The dynamic load capacities are based on a total travel of 100,000 m. When based on 50,000 m, the C values in the table are to be multiplied by 1.26.
|
| Note: Permissible ambient temperature (min. ... max.) |
Only unsealed linear bushings with steel ball retainers may be used at higher temperatures. Make allowance for reductions in load capacity.

| Note: Shaft radial clearance h6 |
Determined from working bore diameter and shaft tolerance statistics. Recommended housing bore tolerance: H6 or H7.

Description
standard linear bushing
Standard (metal)
Closed
Shaft diameter d = 8
With one seal
Version: Standard
Features
- Rugged all-metal design with steel ball retainer for harsh environments and heavy contamination
- Many pockets acting as lubricant reservoirs for extended lubrication intervals or lubrication for life
- Steel ball retainer (shaft diameters 3, 4 and 10 with plastic strip made of POM and shaft diameters 5 and 8 made of PA)
- Closed, for self-supporting shafts
- Balls made of rolling bearing steel
- For use in woodworking, foundries, cement plants
- Pockets collect any dirt that may have worked its way in to prevent the linear bushing from jamming.
- No wiper seals, come with integrated steel retaining rings; higher temperatures allowed with shaft diameters 12 and higher
- Hardened and ground outer sleeve
