Self Aligning Ball Bearing D 130-240Mm
Self Aligning Ball Bearing D 130-240Mm is a double row ball bearing that includes an outer ring with a spherical raceway, an inner ring, and a ball and cage assembly. Self-aligning ball bearings are self-aligning and are not sensitive to shaft deflection and angular misalignment between the shaft and the housing. Due to the spherical raceway, the misaligned contact angle is approximately 4-7 degrees. Therefore, the axial load capacity is low and it is suitable for medium and low radial loads.
Modern self-aligning ball bearings are also maintenance-free (for normal applications) with seals on both sides and “lifetime” grease filling. For design reasons, the allowable angular movement of the sealed self-aligning ball bearing is reduced from 4° to a maximum of 1.5°. In addition to self-aligning ball bearings with cylindrical bores, tapered bores with a tapered bore of 1:12 are often used. In addition, self-aligning ball bearings with a widened inner ring are also available. We can choose the best self-aligning ball bearing design, lubrication and sealing to optimize the bearing's price, performance and service life for specific customer applications.
