Hydraulic bolt tensioners remove uncertainty from couplings

Third Quarter 2020 Hydraulic systems & components

Hydrocam hydraulically operated bolt tensioners offer far greater accuracy compared to other fixing methods. With their superior control and safety, damage to bolts and associated structures is avoided, installation is faster, operation of equipment is optimised and maintenance needs are minimised.

Bolted assemblies are used throughout industry but can present significant challenges. For example, incorrect assembly accounts for around 45% of all fatigue failures, with common problems being insufficient preload, over- or under-tightening and misalignment. Conventional methods for tightening bolts use torque applied by hand, or torque tools. These methods can damage threads and flange faces, leading to re-machining and extra downtime. The bolts may also become loose over time. Hydrocam overcomes these problems by axially stretching bolts and studs, using a predetermined residual load to create a high integrity fixing, which can be mounted and dismounted quickly and safely without damage. It can be supplied as a single tool or incorporated into a multi-tensioner for homogenous tightening; it is intended to be reused with multiple fittings but can also be permanently incorporated into the nut assembly.

Hydrocam is manufactured by Pilgrim, a fully owned SKF company, and supplied ready for use with the tensioner unit, power pack and all relevant fittings; the power pack can be hydraulically, electrically or hand operated. “Hydrocam ensures consistent, safe and precise bolt assembly and fastening. It is saving industry considerable time, effort and cost,” concludes Pilgrim general manager, Damian Lewis.
