Tension bushes
STANDARD SIZES
Tension bushes offer a convenient solution to protect machine parts subject to wear and corrosion in poorly lubrificated environments. They are produced from rolled strip hardened and tempered spring steel and are suitable for applications with low RPM and high specific load or where oscillating movements at low frequency occur. Same easy assembly and disassembly of the spring pins shown in this price list and similar features: the housing hole tolerance has to be H8.
In the free state their external diameter is wider, in the predetermined size, than the hole in which they will be mounted to ensure a comfortable and secure coupling and to ensure, thanks to their elastic properties such an interference that prevents the spilling out of the bushes in dynamic applications even if the hole widens.
For insertion, they require less force than solid bushes, this is usefull to avoid damages to the hole and to the bushes, moreover the chamfers make installation easier.
