Super LB B, closed, 30, with two seals Product Description Super linear bushing Super B (no self-alignment feature) Closed Shaft diameter d = 30 With two seals Low-cost linear bushing for high requirements Steel bearing plates with machined ball guide grooves and optimized ball lead-in chamfers for outstandingly smooth travel and a long service life Without self-alignment feature for transferring lower tipping force along the axial direction High travel speed (5 m\/s) Integrated wiper seals, external seals or no wiper seals Ball retainer and outer sleeve made of PA or POM Balls made of rolling bearing steel No initial lubrication Technical Specs Product attributes Shaft diameter d [mm] 30 Version Standard Format of linear bushings – Closed Series Super B (no self-alignment feature) Seal 2 integrated wiper seals Lubrication Not lubricated Maximum dynamic load capacity Cmax [N] 5860 Maximum acceleration rate amax [m/s²] 150 Maximum permissible linear speed vmax [m/s] 3 Note: maximum permissible speed vmax Speeds of up to 5 m/s possible. Service life is limited by heightened wear to plastic parts. Tests have shown total travel from 50 • 105 m to 100 • 105 m without failure. Length of linear bushing [mm] 68 Outer diameter D [mm] 47 Permissible ambient temperature (min. ... max.) -10 °C ... +80 °C Friction coefficient μ 0.001 ... 0.0025 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] 0.2 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. Footnote minimum static load capacity C0min null Footnote friction force FR 1. One wiper seal: Multiply value with factor 0.5 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.
