Hardened Bush for Bearing and Wear InterfacesThe Hardened Bush is a cylindrical bearing element supplied for applications requiring surface hardness and wear resistance. It is used where sliding contact or rotational interfaces demand a hardened bearing surface to extend component life. OEM assembly and maintenance teams use this component to control wear and maintain alignment.Material and Hardening NotesProduction emphasizes surface hardening and dimensional control to ensure interference fit and bearing clearance. Typical hardening processes are selected based on load and wear expectations. Dimensional inspection validates bore and outer diameter conformity to assembly requirements.Procurement and Supply TermsAvailable for bulk sourcing and scheduled supply. Production planning aligns lead time with batch size and process route. Protective packaging is configured to prevent surface damage during transit.
Product Description
Industrial Applications and Buyer Workflows
Hardened Bush components are applied in rotating shafts, pivot points, and sliding guides where wear resistance improves service intervals. Use-cases include equipment rebuilds, replacement part programs, and OEM integration where tolerance and fit are essential for longevity.
Manufacturing and Quality Control
Manufacturing routes may include turning to nominal dimension, hardening to specified depth, and finish honing to final bore tolerance. Inspection focuses on hardness profile and dimensional conformity. Process controls ensure repeatability for batch orders and provide traceable inspection records.
Ordering and Delivery
Commercial volume procurement is supported. Lead time depends on heat-treatment cycle and post-process finishing. Packaging protects bore and OD surfaces to ensure parts arrive ready for assembly. Buyers should specify fit class and hardness requirement when ordering.
Frequently Asked Questions
Can the bush be supplied to a specific hardness and fit class? Yes. Specify target hardness and interference/clearance fit and production will include corresponding process and inspection steps.
Which production methods are used to achieve hardness? Typical methods include induction hardening or case carburizing followed by finish machining as required.
What inspection evidence is provided? Dimensional inspection and hardness profile records are provided to support incoming verification.
How does order volume affect lead time? Heat-treatment capacity and finishing workload influence lead time. Larger repeat orders enable scheduled runs that reduce turnaround.

Buyer questions
Frequently asked by buyers
Common questions B2B buyers ask before sourcing Hardened Bush. Answers compiled from verified sellers' commercial terms and platform data.
Q: What materials are used to manufacture the hardened bush for high-load applications?
A: Hardened bushes are typically made from high-carbon steels such as 20MnCr5 or 52100, alloy steels, or tool steels, optimized for wear resistance and load capacity.
Q: What heat treatment process is applied to these hardened bushes to achieve durability?
A: These bushes undergo induction or through-hardening heat treatments to develop a surface hardness between HRC 58 to 64 while maintaining a tough, ductile core.
Q: What types of hardened bushes are available and how do they differ?
A: Available types include straight, flanged, headed, and shouldered bushes, each providing different mounting and locating options tailored to specific mechanical assembly requirements.
Q: How tight are the machining tolerances on the hardened bush inner diameter?
A: Hardened bushes are precision-ground with inner diameter tolerances conforming to ISO H7/h7, ensuring tight fits and reliable performance in critical applications.
Q: Are these hardened bushes suitable for corrosive environments?
A: Yes, optional stainless steel versions and protective coatings such as black oxide or phosphate treatments can be applied for enhanced corrosion resistance.
Q: Can customized sizes or non-standard designs be produced?
A: Yes, manufacturing can be customized based on customer CAD drawings, with size ranges typically from 10 mm ID upward and configurable lengths and features.
Q: What are common industrial applications where hardened bushes are used?
A: They are widely used in automotive suspensions, die sets, construction machinery pivots, agricultural equipment joints, and hydraulic cylinder wear sleeves.
