Frequently Asked Questions
Q What does "self-lubricating" mean for graphite brass bearings?
Self-lubricating means the bearing does not require external oil or grease. Graphite embedded in the brass matrix naturally migrates to the surface during friction, forming a thin lubricating film that reduces wear and extends service life — with zero maintenance intervention.
Q What temperature range can Youyi Bearing products operate in?
Youyi Bearing products support a broad operating temperature range of -40°C to +300°C, making them suitable for both cryogenic and high-heat industrial environments.
Q Can Youyi Bearing manufacture custom bearings to specific dimensions or material requirements?
Yes. Youyi Bearing offers scientifically tailored raw material formulations and dedicated CNC machining solutions to precisely match bespoke specifications. Their vertical integration — from copper foundry to finished product — enables full customisation with strict quality control.
Q Are the bearings suitable for use in corrosive or harsh environments such as seawater?
Yes. The brass matrix provides excellent corrosion resistance and impact toughness, capable of withstanding dynamic stresses up to 100 N/mm². These bearings are specifically designed to perform reliably in challenging conditions including seawater exposure and dusty surroundings.
Q How does Youyi Bearing ensure product quality throughout the manufacturing process?
By leveraging vertical supply chain integration — with an in-house copper foundry and CNC precision machining — Youyi Bearing maintains quality control at every stage from raw material to final delivery. Mature production controls help consistently achieve one of the industry's highest product qualification rates.
Q What industries or applications are Youyi Bearing products best suited for?
Youyi Bearing products are ideal for high-end industrial manufacturing applications that demand self-lubrication, extreme environment resistance, and high precision. This includes heavy machinery, marine equipment, construction machinery, and other sectors requiring durable, maintenance-free bearing solutions.
