Superbolt range of expansion sleeve coupling bolts offers a wide range of flexibility in application – suitable for through hole couplings, blind hole couplings – even applications requiring accurate location of components without axial load. The expansion bolts can be retrofitted to replace traditional interference and other types of coupling bolts most reliably and cost effectively.
The mechanical expansion bolt, now known as EzFit, is a long-established product with design capability for all types of couplings requiring truly fitted bolts, commonly used for Hydro turbines, Marine propulsion drive coupling, large motors and gear rings that require component location accuracy.
HyFit hydraulic expansion bolt is a newly advanced product that can replace all designs of coupling bolts. Main applications are found in power generation including conventional steam, high efficiency gas, hydro and wind turbines. With HyFit installed, customers benefit from both operation improvements in coupling performance along with saving time during plant maintenance periods. The innovative design features significantly reduce the risk of causing damage to the bolt or bolt hole, and address safety issues commonly experienced with alternative coupling bolt solutions.
The extensive product range of HyFit and EzFit expansion bolts provides the best options to fit your application. Furthermore, the unique features and advantages of both hydraulic and mechanical expansion sleeve coupling bolts can be combined to suit specific requirements.
