RECIRCULATING BALL BUSH ~ISO9448-3
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).
Socket: - Steel, hardened 62 ± 2 HRC
Ball carrier: - Aluminium
Balls: - Steel, hardened, conforming to DIN 5401
Outside diameter precision ground.
The bush is accurately positioned by means of H5 slip-fit hole. The slip-fit adhesive (order no. 281.648) is used solely to secure the bond.
ADVANTAGES OF SLIP-FIT BONDING:
- High accuracy and stability
- Ease of interchangeability
We do not recommend press-fitting the bush since that causes unacceptable alteration to the shape of the bush.
Fastening within the locating hole using DIN 472 locking rings is possible.
