This 2308E-2RS1TN9 double-row self-aligning ball bearing is double-sealed, and has a cylindrical bore, polyamide/nylon cage, and normal clearance rating. It is suitable for applications supporting moderate radial loads and moderate to low thrust loads. This 2308-2RS bearing has concave sphere housing rings to compensate for static angular misalignments between the shaft and housing in applications subject to shaft deflections or mounting errors. Because this bearing type has the lowest operational friction of all rolling bearings, it runs cool at high speeds. This bearing is made of low-alloy, through-hardened chromium steel for durability and resistance to deformity under heavy loads. The bearing 2308-2RS has a straight bore for fitting on a conventional cylindrical shaft. Contact seals on both sides of the bearing keep out contaminants such as dirt and grime and hold in lubricant applied at manufacturing that lasts the lifetime of the bearing. This bearing has an injection-molded snap-type cage made of glass fiber reinforced polyamide 66 to prevent the balls from coming into contact with each other during use, reducing friction, vibration, and noise. This cage type can be used at operating temperatures up to 120 degrees C (250 degrees F). This 2308E-2RSTN9 bearing has a normal radial internal clearance designation, making it suitable for applications where the load and speeds do not result in thermal expansion. This clearance provides latitude for self-realignment and compensates for static and dynamic alignment errors. Additionally, this bearing is produced to PN (normal) tolerances in accordance with ISO standards for quality assurance. This 2308E-2RS1TN9 self-aligning ball bearing is for use in commercial and industrial applications including film processing equipment, office automation, vertical spinning equipment, and industrial countershafts, among others.
