Hot Products
High Quality Oil-free Bearing Slide Rails from China Suppliers - Durable Self-lubricating Components from Our Factory
Product Features
🔧
Self-lubricating and maintenance-free
There is no need for extra oiling because graphite naturally seeps out during friction to produce a lubricating layer. A broad operating temperature range of -40°C to +300°C is suitable.
🛡️
Extreme environment resistance
The brass matrix provides impact toughness and corrosion resistance, withstanding dynamic stresses of up to 100N/mm². Perfect for challenging circumstances including exposure to seawater and dusty surroundings.

Frequently Asked Questions
Q
What makes graphite bronze bearings self-lubricating?
Graphite is embedded within the bronze matrix. During operation, friction causes the graphite to gradually seep out, forming a continuous solid lubricating film on the contact surface — eliminating the need for external oil or grease.
Q
What temperature range can your self-lubricating bearings handle?
Our graphite bronze bearings operate reliably across a wide temperature range of -40°C to +300°C, making them suitable for both low-temperature refrigeration systems and high-temperature industrial applications.
Q
Can Youyi Bearing produce products to custom specifications?
Yes. We offer fully customized solutions including tailored raw material compositions and specialized CNC machining. We accommodate unique dimensions, tolerances, and performance requirements for each customer project.
Q
Which international standards does Youyi Bearing comply with?
We produce bronze and brass bearings in compliance with DN, BS, EN (DNEN), SS, NS, UNS, SAE, and China's GB standards, ensuring compatibility with global engineering projects and procurement specifications.
Q
Are your bearings suitable for harsh environments like seawater or dusty conditions?
Absolutely. The brass matrix provides strong corrosion resistance and impact toughness, supporting dynamic stresses up to 100N/mm². The bearings are widely used in marine, mining, and heavy industrial environments.
Q
What manufacturing processes does Youyi Bearing use?
We manufacture all products using electrolytic copper as raw material through centrifugal casting, continuous casting, and extrusion processes, supported by our in-house copper foundry and CNC high-precision machining equipment for end-to-end quality assurance.
