TECHNICAL DATA
MODEL SELECTION & CROSS-REFERENCE
KB020AR0 belongs to the KB Series and has a bore of 2.000 in (50.8 mm), outside diameter of 2.625 in (66.675 mm) and radial section of 0.3125 in. Use the land dimensions in the table when reviewing the shaft and housing shoulders. The section drawing identifies the dimension symbols; send your mating-part drawing to confirm fits and tolerances.
Angular contact selection starts with axial load direction and the bearing arrangement. Provide the opposing bearing position, preload or clearance requirement, shaft speed and temperature so the pair and fits can be reviewed.
This reference is open. Include the housing protection and lubrication method in the enquiry, especially for dust, moisture or washdown exposure.
The reference dynamic radial capacity is 601 lb; static radial capacity is 1,090 lb. The listed dynamic thrust capacity is 1,380 lb. These values describe the catalogue reference. Final PRIUS ratings, clearance and service life require confirmation against the application.
These references match bore, outside diameter and radial section. Contact geometry, land dimensions, sealing and ratings may differ; interchangeability needs a drawing review.
