Rubber Information<br />
The rubber blocks and elements used in <strong>Renold</strong> Hi-Tec <strong>Couplings</strong><br />
are key elements in the coupling design. Strict quality control is<br />
applied in the manufacture, and frequent testing is part of the<br />
production process.<br />
Rubber-in-Compression<br />
These designs use non-bonded components, which allows for<br />
many synthetic elastomers to be employed.<br />
These elastomers offer considerable advantages over others for<br />
specific applications, giving <strong>Renold</strong> Hi-Tec <strong>Couplings</strong> a<br />
distinctive lead in application engineering in specialised areas.<br />
Rubber in Shear<br />
These designs use high tear strength, low creep natural rubber<br />
developed for diesel engine drives.<br />
All rubber in shear couplings are 100% tested to ensure<br />
bond/moulding integrity.<br />
