Recirculating ball linear bearing 2081.69.0 series

The recirculating ball bush is used when very large paths (strokes) are travelled. This is only limited by the mounting situation. In comparison to guides with ball cage, however, the lower dynamic load figures (C) should be observed. Despite the high number of ball tracks, fewer balls are in usage. For optimum service life, a movement path (stroke) of three times the length of the recirculating ball bush is recommended (3 x l1). MATERIAL: Socket: - Steel, hardened 62 ± 2 HRC Ball carrier: - Aluminium Balls: - Steel, hardened, conforming to DIN 5401 EXECUTION: Outside diameter precision ground.
