Self aligning ball bearing:1308

Basic Parameters

The numbers in the bearing 1308 mean the following: “1 ”represents that the bearing type is a ball bearing, “3 ”represents the width series of the bearing, and “08” represents that the inner diameter of the bearing is 40 millimeters.The 1308 bearing is a self-aligning ball bearing with an outer ring with two raceways and an inner ring with balls and a cage assembly. The model number of this type of bearing typically follows the ISO standard, where "13" indicates the bearing's outer diameter series, and "08" indicates the bearing's width series. Therefore, the outer diameter of the 1308 bearing is approximately 90 millimeters, and the width is 23 millimeters.The 1308bearing is a rolling element bearing that is uniquely designed to withstand misalignment of the shaft with respect to the bearing housing. It has two volleyball balls and the outer ring has a common spherical raceway that enables the bearing to self-align. The inner diameter of the 1308 ETN9 is 40 mm. The outer diameter is 90 mm. The width is 23 mm. The 1308 ETN9 bearing is versatile and adaptable, ensuring smooth operation even when not perfectly aligned. Its unique design helps to prevent the bearing from being stressed, thus extending its service life.

Product Application

The 1308 bearings are suitable for applications where misalignment is caused by belt seat errors or shaft deflection. • Automotive: for power steering systems, drive shafts and steering column joints where angular deviations are frequent. • Agricultural: essential in agricultural equipment such as tractors and harvesters, where uneven terrain can cause shaft eccentricity. • Textiles: used on spinning machines and looms, where smooth, consistent rotation is essential. • Conveyor systems: suitable for belt systems to maintain consistency in belt tension and alignment, especially for long-distance conveyors. • Mining and construction: used in crushers, vibrating screens and heavy machinery where strict handling is required and shaft deflection can occur.
