1 Pc Brass-Graphite-Copper Sleeve Bearing, 22 × 32 × 30 mm, ID 20/22/25/28/30 mm

Description

• Made of environmentally friendly H62 brass with precision-machined H7 bore tolerance (00.018 mm) and IT6 outside-diameter tolerance (00.009 mm).
• High-purity graphite particles form an automatic lubricating film during operation, maintaining a stable coefficient of friction of 0.080.12 and reducing maintenance needs.
• Suitable for high-temperature and dusty environments.
• Surface roughness is controlled to Ra 0.8 m for a close fit with the drive shaft and reduced operating noise.
• Compatible with drive systems using shaft diameters of 8100 mm; suitable for textile machinery, industrial robots, and new-energy vehicles.
• We strive to provide high-quality products and enthusiastic service. Please contact us with any questions; we will respond within 24 hours.

Type: Mechanical component Dimensions: Inside diameter outside diameter height This bearing is made from high-strength copper-based materials and uses embedded solid-lubricant technology. It is designed specifically for industrial automation and precision transmission systems. High-purity graphite particles are evenly embedded in the bearings inner wall, creating a natural self-lubricating system that eliminates the need for lubricant additives, effectively reduces friction, and lowers equipment maintenance costs. With a coefficient of friction as low as 0.080.12, it provides stable lubrication even in harsh environments, including high temperatures from -20C to 280C, dust, and moisture. This helps prevent seizing and wear caused by insufficient lubrication in conventional bearings. Applications include spherical plain bearings for industrial robots, feed systems for CNC machine tools, transmission units for packaging machinery, guide components for hydraulic systems, and transmission mechanisms for new-energy equipment. Widely used in textile machinery such as carding machines and looms; printing machinery such as offset presses and flexographic printing machines; mining machinery such as conveyors and crushers; agricultural machinery such as tractors and harvesters; and automotive parts such as steering and suspension systems.
