Compact LB, 20, without seal, not lubricated Product Description Compact linear bushing Shaft diameter d = 20 Without seal Radial clearance: Standard Version: Standard Not lubricated Low-cost linear bushing for general requirements Small outer dimensions and highly compact construction High dynamic load rating and long service life due to hardened segmental load-bearing plates with ball conformity in the running track High travel speed (5 m\/s) Integrated wiper seals, external seals or no wiper seals Normal radial clearance Not greased Simple mounting: Just press on – no additional retention needed Many pockets acting as lubricant reservoirs for extended lubrication intervals or lubrication for life Pockets collect any dirt that may have worked its way in to prevent the linear bushing from jamming. Integrated metal retainer about 0.1 mm larger than outer diameter (shaft diameters 12 to 50) for secure fit in housing bore Technical Specs Product attributes Shaft diameter d [mm] 20 Version Standard Format of linear bushings – Closed Series Compact Seal without wiper seals Lubrication Not lubricated Maximum dynamic load capacity Cmax [N] 1410 Maximum acceleration rate amax [m/s²] 150 Maximum permissible linear speed vmax [m/s] 5 Radial clearance normal radial clearance Length of linear bushing [mm] 30 Outer diameter D [mm] 28 Permissible ambient temperature (min. ... max.) -10 °C ... +80 °C 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 maximum static load capacity C0max null 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.
