Oilless Bushing Bearing

Definition

Self-lubricating copper sleeves, also known as graphite copper sleeves, self-lubricating wear-resistant sleeves, self-lubricating bearings, self-lubricating shaft sleeves or self-lubricating guide sleeves, are mechanical bushings that can maintain good sliding performance without the need for additional lubricating oil. Its main material is high-strength brass, and solid lubricants (such as graphite) are evenly inlaid on the surface of the copper sleeve. This structural design enables the copper sleeve to automatically release lubricating substances during operation, forming a stable lubricating film, which significantly reduces the friction coefficient and wear rate.

 

Core value

Dual-effect lubrication system: Graphite /PTFE inlaid + porous oil storage structure, with a friction coefficient as low as 0.08

Military-grade durability: Special copper alloy formula (CuSn8/CuPb24) increases wear life by five times

Ready-to-use: Pre-lubricated, no running-in period required

Global validation: Serving over 50 countries' heavy industry customers

 

Three major technological breakthroughs

Honeycomb oil storage technology: Laser processing of micro-holes increases the amount of lubricant retained by 40%

Gradient copper layer: A gradually changing structure from a high-hardness surface layer to a tough substrate

Environmentally friendly formula: Lead-free design

 

Industry solutions

Construction machinery: Excavator boom hinge point (dust-proof design)

Automobile manufacturing: Heavy truck balance shaft (maintenance-free version)

Marine system: Steering gear bearings (Seawater corrosion-resistant type)

Food equipment: Filling machine rotary table (FDA Certified model)

 

Service support

Rich variety: over 150 standard models

Customized services: Non-standard dimensions/Special oil tank design
