2Pcs ID 18mm,Brass Graphite Copper Sleeve,Bearing Bushings,18x22x30mm,2pcs

Crafted from environmentally friendly H62 brass, this product achieves an H7-grade internal bore tolerance (0-0.018mm) and an IT6-grade external diameter tolerance (0-0.009mm) through precision machining. High-purity graphite particles automatically form a lubricating film during operation, maintaining a stable friction coefficient of 0.08-0.12, eliminating the need for frequent maintenance and making it particularly suitable for high-temperature and dusty environments. The surface roughness is controlled to Ra ≤ 0.8μm, ensuring a zero-clearance fit with the drive shaft and effectively reducing noise generated by equipment operation. It is compatible with drive systems with shaft diameters of 8-100mm, covering applications such as textile machinery, industrial robots, and new energy vehicles. We are committed to providing high-quality products and enthusiastic service. If you have any questions, please feel free to contact us and we will answer your questions within 24 hours.
