| Note: permissible ambient temperature (min. ... max.) |
Higher temperatures are only admissible at linear bushings without wiper seals with ball retainers made of steel. Make allowance for reductions in load capacity.

| Friction coefficient μ |
0.001 ... 0.004
|
| 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.

| Footnote 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.

Description
Standard linear bushing
Standard (metal)
Closed
Shaft diameter d = 20
With two seals
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
