Norelem offers tensioning solutions02 September 2020
Sprocket sets and tensioning pulleys for belt or chain drives are now available from component supplier norelem, allowing engineers to create custom tensioning solutions designed to their needs.
At the heart of each new unit is the clamping element. Cushion, support, tensioning and dampening is all provided by the multifunctional spring bodies manufactured from highly elastic and dimensionally stable natural rubber. The rubber is said to be maintenance-free, tear-off proof and has a high chemical resistance. Meanwhile, the universal clamping elements are available in steel and stainless steel. With the steel versions, front fastening is available when rear-mounting is not possible.
The ball bearings of this component are sealed both sides and are maintenance-free due to lubrication that will last the lifetime of the product. For flexibility, the sprocket can be moved on the screw and thereby adapted to the chain track. In the duplex and triplex versions, precise spacer sleeves ensure that the chain has correct guidance.
