2081.69._.1 Recirculating ball bush with collar ~ISO9448-7
Description:
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 (1): Steel, hardened 62 ± 2 HRC
Ball carrier (2): Aluminium
Balls (3): Steel, hardened, conforming to DIN 5401 Execution:
Outside diameter precision ground. Note:
The attachment is with 3 retaining elements, from Ø d1 = 38 with 4 retaining elements , which are included in delivery (Order No: 207.45 - retaining element incl. socket head bolt DIN 6912, M6x20, head Ø 13).
↗ Matching guide combinations, see selection matrix at the beginning of chapter D.
↗ For service life calculation and dynamic load figures, see the end of chapter D.
↗ Assembly guidelines / size tables and tolerances at the end of chapter D.
Recirculating ball bushes only with red guide pillar = .30 combinable.
