Bronze & Engineering Plastic Bushings Manufactured by Quickmachine
Our custom machined bushings are critical wear-resistant sliding bearing components widely used for rotational and linear friction reduction in all types of industrial equipment. Designed for stable low-friction operation, strong load-bearing capacity, shock absorption and extended service life, they are extensively adopted in CNC equipment, automation production lines, hydraulic systems, lifting machinery, textile machinery, engineering vehicles and various mechanical transmission assemblies.
We supply multiple high-performance raw material options including cast iron HT15-33, HT20-40, tin bronze ZQSn10-1, aluminum bronze ZQA19-4, ultra-high molecular weight polyethylene UHMWPE and other customized alloys & engineering plastics. All products are finished by strict CNC precision machining. For metal bushing variants, quenching heat treatment is available to achieve 58–62 HRC surface hardness, greatly enhancing abrasion resistance, compressive strength and dimensional stability. Compared with ordinary powder metallurgy bushings, our solid machined bushings feature tighter dimensional consistency, better anti-seize performance and stronger heavy-load resistance. The machining tolerance is rigidly controlled at ±0.0175 mm, effectively preventing play, jitter and abnormal noise during long-term continuous reciprocating and rotating operation, upgrading the running stability and maintenance cycle of the whole equipment.
Blank workpieces can undergo multiple post-processing treatments such as precision fine boring, deburring, surface polishing, oil groove machining and anti-rust passivation to optimize lubrication storage capability, corrosion resistance and surface finish. We also offer secondary processing like flange forming, counterbore, pin hole drilling and keyway processing to fit different shaft fits, mounting bases and assembly installation structures. Custom overall dimensions up to maximum Ø500×1430 mm are supported. Standard straight sleeve, flanged, stepped, self-lubricating embedded and non-standard special-shaped bushing styles can all be customized to meet diverse friction and installation demands from different industries.
