Super LB A, open, 20, without seal Product Description Super linear bushing Super A (with self-alignment feature) Open Shaft diameter d = 20 Without seal 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 Compensates for shaft deflection and misalignment up to 30' Open linear bushing on fully supported shafts for applications where other linear guides tend to warp due to imprecise substructures. High travel speed (5 m\/s) With longitudinal seal No initial lubrication 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 Technical Specs Product attributes Shaft diameter d [mm] 20 Version Standard Format of linear bushings O - Open Series Super A (with self-alignment feature) Seal without wiper seals Lubrication Not lubricated Dynamic load capacity C [N] 2570 Note: dynamic load capacity C The load capacities apply for the main direction of loading. 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] 45 Outer diameter D [mm] 32 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] 0.07 Static load capacity C0 [N] 1180 Note: static load capacity C0 The load capacities apply for the main direction of loading.
