Timken ER23 Wide Inner Ring Insert Ball Bearing

The Timken Fafnir ER23 wide inner ring insert ball bearing is a relubricatable mounted bearing insert engineered to support shafts under moderate to heavy radial loads. It uses dual set screw locking (two M8 × 1.25 screws) to secure the shaft and a cylindrical outside diameter designed for installation in compatible housed bearing units. Constructed from bearing steel with a heat-stabilized nylon cage, it employs narrow shroud contact seals to retain lubricant while protecting against contaminants. Key dimensions include bore 1-7/16 in (36.51 mm), outside diameter 2.834 in (72.00 mm), inner ring width 1.781 in (45.42 mm), and outer ring width 0.938 in (23.75 mm); the basic outer ring size is 207 and the unit weighs approximately 1.14 lb (0.52 kg). Dynamic radial load rating is 6,400 lbf (28,416 N) and static radial load rating is 3,440 lbf (15,274 N). Typical applications span conveyors, agricultural machinery, packaging equipment, material handling systems, fans, blowers, and food processing equipment in industrial settings.
