POM composite straight bushing, inch sizeSKF POM composite straight (cylindrical) bushings, inch sizes, are suitable for oscillating, rotating and linear movements, and can accommodate radial loads. After initial grease fill, they are optimized for minimal maintenance under tough operating conditions. Pockets in the sliding surface serve as grease reservoirs. Relubrication can extend bearing service life considerably. Despite their compact design, they can accommodate heavy loads.
- Cost-effective with long service life
- Very good frictional properties
- High load carrying capacity
- High sliding velocity
