Gripper Jaws FAQ
What gripper jaws can you manufacture?
Rock gripper jaws, coal gripper jaws, ore gripper jaws, custom gripper profiles, gripper jaw inserts, and replacement gripper components. All sizes and attachment styles available.
What materials are best for high-wear gripper jaws?
Bisalloy and Hardox ultra-high strength wear-resistant steel are the primary materials. 4140 steel with carburising provides wear resistance. Tool steel for custom tooling inserts. Tungsten carbide inserts for extreme wear.
What tolerances can you hold on gripper profiles?
Gripper jaw profiles held to ±0.1mm standard. Contact surface flatness and parallelism within ±0.05mm. Pin bore tolerances to ±0.02mm for optimal fit.
What is the typical lead time for gripper jaws?
Standard gripper sets: 2–3 weeks. Custom profiles: 3–4 weeks. Bulk orders: lead times negotiated. Lead times depend on material availability and hardfacing.
Can you manufacture custom gripper profiles?
Yes. Custom jaw profiles optimised for your rock type, ore grade, and operational requirements. CAD design assistance available.
Do you offer hardfacing for extended wear life?
Yes. Hardfacing overlay on gripper jaw contact surfaces extends wear life 2-5x. Custom hardface thicknesses and compositions available.
