Rexroth R061202010
Standard linear bushing
Standard (metal)
Adjustable
Shaft diameter d = 20
With two seals
Design: normal"
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
Seal-free and with steel ball retainers for temperatures well above 80°C or under vacuum
Radial clearance adjustable
Integrated wiper seals for high contamination
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
Steel ball retainer (shaft diameters 5 and 8 with plastic retainer made of PA)
Balls made of rolling bearing steel

| Outer diameter D [mm] | 32 |
| Permissible ambient temperature | -10 °C ... +80 °C |
| Footnote 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 ? | 0,001 ... 0,004 |
| Footnote friction coefficient ? | 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. |
| Permissible ambient temperature (min) [°C] | -10 |
| Breakaway force [N] | 12 |
| Friction coefficient ? max. | 0.004 |
| Friction coefficient ? min. | 0.001 |
| Footnote friction force FR | One wiper seal: Multiply value with factor 0.5 |
| Friction force [N] | 4 |
| Footnote 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. |
| 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. |
| Footnote breakaway force | One wiper seal: Multiply value with factor 0.5 |
| Minimum static load capacity C0min [N] | 860 |
| Maximum static load capacity C0max [N] | 1250 |
| Minimum dynamic load capacity Cmin [N] | 1170 |
| Footnote maximum static load capacity C0max | |
| Radial clearance shaft h6/bore K7 [µm] | +31,-2 |
| Radial clearance shaft/bore h6/H7 [µm] | +49,+16 |
| Permissible ambient temperature (max) [°C] | +80 |
| Rows of balls | 5 |
| Friction force FR footnote 2 | Frictional drags generated by linear bushings with integrated wiper seals on two sides when not under radial load. The frictional drags depend on speed and lubrication. |
