Description:

Therecirculating ball bush isused when very large paths (strokes)are travelled.Thisisonlylimitedbythemountingsituation. Incomparisonto guideswithballcage,however,the lowerdynamic load figures (C) shouldbeobserved.Despite the high numberof ball tracks, fewerballsare inusage.

For optimum service life,a movement path (stroke) of three times the lengthof the recirculatingballbushisrecommended ( 3 x 1 _ { 1 } ) #

Material:

Socket (1):Steel,hardened 6 2 ± 2 HRC Ball carrier (2): Aluminium Balls(3):Steel,hardened,conformingtoDiN5401

Execution:

Slip-Fit Bonding:

Thebush isaccuratelypositionedbymeansof H5slip-fithole.Theslip-fit adhesive(orderno.281.648) isusedsolelytosecurethebond.

Advantagesof slip-fitbonding:

- High accuracy and stability - Ease of interchangeability

We do not recommend press-fitting the bush since that causesunacceptable alteration to the shape of the bush. Fasteningwithinthelocating holeusingDiN472lockingringsispossible.
