Standard linear bushing<br>Standard (metal)<br>Closed<br>Shaft diameter d = 12<br>With two seals<br>Version: Standard 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
Specifiche
Specifications
| Shaft diameter d [mm] | 12.0 |
| Version | Standard |
| Format of linear bushings | – Closed |
| Series | Standard (metal) |
| Type | Linear bushing |
| Seal | 2 integrated wiper seals |
| Lubrication | Not lubricated |
| Maximum dynamic load capacity Cmax [N] | 480.0 |
| Maximum acceleration rate amax [m/s²] | 100.0 |
| Maximum permissible linear speed vmax [m/s] | 2.5 |
| Length of linear bushing [mm] | 32.0 |
| Outer diameter D [mm] | 22.0 |
| Permissible ambient temperature (min. ... max.) | -10 °C ... +80 °C |
| 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. |
| Weight [kg] | 0.04 |
| Footnote breakaway force | One wiper seal: Multiply value with factor 0.5 |
| 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 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 shaft radial clearance h6 | Determined from working bore diameter and shaft tolerance statistics. Recommended housing bore tolerance: H6 or H7. |
| Footnote friction force FR | One wiper seal: Multiply value with factor 0.5 |
| Breakaway force [N] | 6 |
| Dimension C h12 [mm] | 32 |
| Dimension C1 H13 [mm] | 22.6 |
| Dimension C2 [mm] | 1.3 |
| Dimension D [mm] | 22 |
| Dimension D1 [mm] | 20.5 |
