Frequently Asked Questions
Q
What is the operating temperature range of Youyi graphite brass bearings?
Youyi graphite brass bearings are designed to operate across a wide temperature range of -40°C to +300°C, making them suitable for both extremely cold and high-heat industrial environments without requiring additional lubrication.
Q
Do Youyi bearings require regular oiling or maintenance?
No. These are self-lubricating, maintenance-free bearings. The embedded graphite automatically seeps out during friction to form a continuous lubricating film, eliminating the need for periodic oiling or grease application.
Q
What dynamic load capacity do these bearings support?
The brass matrix structure provides high impact toughness, supporting dynamic loads up to 100 N/mm². This makes the bearings ideal for high-load applications in demanding industrial settings.
Q
Can Youyi Bearing provide customised bearing solutions?
Yes. Youyi Bearing offers scientifically tailored raw material formulations and dedicated machining solutions to match bespoke specifications. From raw material development to finished product delivery, their in-house CNC high-precision machining system enables full vertical integration.
Q
Are Youyi bearings suitable for use in corrosive or harsh environments?
Absolutely. The brass matrix provides excellent corrosion resistance, making these bearings well-suited for harsh conditions including dusty environments, seawater exposure, and other chemically challenging industrial applications.
Q
What sets Youyi Bearing apart from other bearing manufacturers?
Youyi Bearing combines independently developed core technologies, an in-house copper foundry, CNC end-to-end precision machining, and a vertically integrated supply chain. This results in consistently high qualification rates, short delivery cycles, and competitive pricing — without compromising on performance or customisation quality.
