Nord-Lock wedge-locking technology secures bolted joints with tension instead of friction. The system is composed of a pair of lock washers with cams on one side and radial teeth on the other.
Nord-Lock wedge-locking products secure the fastener in a joint which cannot be loosened even when subjected to extreme vibration or dynamic loads. The Nord-Lock range includes steel construction washers, wheel nuts, combi bolt washers and custom solutions.
Superbolt multi-jackbolt tensioners (MJTs) take the high preload requirements in large diameter bolting and break it down into manageable torques using the jackbolts threaded through the nut body.
PIVOT PIN TECHNOLOGY
Lug wear is a common problem with all machinery. Repairs involve a costly, time-consuming process with significant downtime and must be repeated several times over a machine’s life.
With the Expander System, the repair can be carried out directly in the worn mountings without welding and line boring – a permanent solution to lug wear.
HYDRAULIC BOLT TENSIONING
Boltight solutions make it possible to tighten and loosen multiple bolts simultaneously using high-pressure hydraulics.
Bolt tensioners stretch the bolt before the nut is wound down under zero friction, ensuring extreme accuracy, speed, uniformity and safety of any bolt tightening situation.
