High Quality Oil-Free Bearing Slide Rails from China Suppliers | Reliable Factory Manufacturing Solutions
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 Youyi Bearing's graphite bronze bushings self-lubricating?
The graphite embedded in the bronze matrix naturally seeps out during friction, forming a continuous lubricating film on the bearing surface. This eliminates the need for manual oiling or external lubrication systems throughout the product's service life.
Q
What temperature range can these bearings operate in?
Youyi Bearing's self-lubricating bearings support a broad operating temperature range of -40°C to +300°C, making them suitable for both extreme cold and high-heat industrial environments.
Q
What international standards do your products comply with?
Our products can be manufactured to meet a wide range of international standards including DIN, BS, EN (DNEN), SS, NS, UNS, SAE, as well as China's GB standards. This flexibility ensures seamless integration into projects across different regions and industries.
Q
Can Youyi Bearing produce custom-specification bearings?
Yes. We offer fully customized solutions with scientifically formulated raw material compositions and specialized CNC machining. Each product is tailored to precisely match the customer's dimensional, load, and environmental requirements.
Q
What manufacturing processes are used in production?
All products are manufactured using electrolytic copper as raw material through centrifugal casting, continuous casting, and extrusion processes, combined with CNC high-precision machining for end-to-end quality assurance.
Q
Are your bearings suitable for harsh environments such as seawater or dusty conditions?
Absolutely. The brass matrix used in our bearings provides excellent impact toughness and corrosion resistance, withstanding dynamic stresses of up to 100N/mm². They are specifically designed to perform reliably in challenging conditions including marine (seawater) and dust-heavy industrial environments.
