“This Bowden cable working in push and pull direction was a real eureka moment for us. In our internal tests, it outshone all previous ideas in terms of smoothness of movement and functional reliability” reports Dirk Strauch of Avola. Owing to its application-specific design calculation, the push/pull cable from RINGSPANN RCS is neither affected by the weight of the three-phase motor nor by the inclination of the saw blade – it follows all movements, meaning that positioning the height by lever is never any trouble. “Earlier Bowden cable products often proved to be very unmanageable and required far too much effort and strength for their actuation alone”, reports Strauch. The push/pull cable customised for Avola on the other hand retains its functional reliability and smoothness of movement, even at high loads and in any position. These operation elements of the series 283 from RINGSPANN RCS can transfer pulling forces of up to 4500 N and pushing forces of up to 3150 N. As well as the lifetime lubrication of these push/pull cables, the teflon coating of the inner member also makes an important contribution to the low-loss force transmission. For it ensures that the inner member always remains freely movable and slidable in its guide sleeve despite the spiral-shaped twisting explained by its function.
