Product Description

Mechanical Expansion Bolts

mechanical expansion bolts offer tremendous radial expansion and joint clamping power in one bolting system. They are specially designed for rotating couplings or alignment systems that require the bolts to transfer forces in shear.
This innovative product replaces large fitted or interference fit bolts, no modifications required. The key to this solution is
the split expansion sleeve that mates with the customers' machined holes. The split sleeve requires less tolerance on mating parts than is traditionally required with interference fit, saving critical machining time.

A Type	B Type	C Type
* Mechanical expansion bolt for threadless bore * Access and operation from one side * Dimension on request	* Mechanical expansion bolt for blind holes * Access and operation from one side * ∅ 28 – 165mm	* Mechanical expansion bolt for through-holes * Access and operation from both sides * ∅ 28 – 165mm

Standard Range
EzFit mechanical expansion bolts can be designed using latest FEA technology for any type of coupling with bolts of diameter 20mm (3/4″) or upwards.
Unique features and advantages of both hydraulic and mechanical expansion sleeve coupling bolts can be combined to best suit your specific requirements.
