SF-1F Self-Lubricating Standard Metric Flange Bearing Bushing - Self-Lubricating, Low Friction, Steel + Copper

Product Description:

SF-1F self-lubricating flange bushing is a high-performance, low-friction oil-free lubricated bearing kit with a steel + copper composite structure and PTFE material embedded on the surface. It can achieve long-term stable operation without external lubrication. Its friction coefficient is as low as 0.08~0.20 (dry lubrication), which significantly reduces mechanical wear and maintenance costs. This product is suitable for a variety of industrial scenarios, including printing machinery, textile machinery, tobacco machinery, fitness equipment, hydraulic systems, gear pumps, etc., especially for occasions where frequent refueling is not possible or difficult.
