CONNEX external spring bushes
Absorbing in tough environments.
CONNEX external spring bushes are used in stationary or slowly rotating shafts or bearing journals that are subjected to high levels of wear and tear. The CONNEX external spring bush is an easily exchangeable component that takes on this wear and tear itself, meaning that the high-value component – the shaft itself – does not have to be replaced so soon.
- Easy, cost-effective fitting and removal.
- Less damaging material stress.
- High abrasion resistance, low wear and tear.
