Solutions for bolted joints in engines and gearboxes
Key challenges
Continuous vibration and high loads can cause joints to lose preload, leading to misalignment, wear, and downtime. Nord-Lock® wedge-locking washers secure the joint and maintain clamp load under dynamic conditions.
Vibration and operational forces can reduce preload, causing joint instability and reduced performance. Superbolt® tensioners deliver precise and uniform preload for stable and reliable operation.
Loosening joints increase maintenance needs and risk unplanned shutdowns. Nord-Lock® wedge-locking washers and Superbolt® tensioners keep joints secure, reducing maintenance and improving uptime.
Varying loads, space constraints, and maintenance strategies make standard solutions insufficient. Nord-Lock Group provides application-specific solutions and expert guidance to ensure optimal performance.
Loss of preload can cause joint movement, leading to misalignment and increased wear. Nord-Lock® wedge-locking washers and Superbolt® tensioners maintain clamp load and ensure stable alignment over time.
Defense applications require proven performance under extreme conditions. Nord-Lock Group solutions are tested according to key military shock and vibration standards, including MIL‑STD‑901D and NASM 1312‑7, as well as UK MOD Def Stan 00‑35. NSN and NCAGE codes support secure, compliant sourcing for artillery and weapon systems.
