TECHNICAL DATA
APPLICATION & INTERCHANGE REVIEW
KA020AR0 is an open Type A reference with a 2.000 in bore, 2.500 in outside diameter and 0.250 in section. In a compact rotary assembly, the axial load direction and the position of the opposing bearing determine the arrangement to review.
The contact geometry changes. Review axial location, radial and moment loads, pairing and ratings before specifying a different suffix.
MODEL SELECTION & CROSS-REFERENCE
KA020AR0 belongs to the KA Series and has a bore of 2.000 in (50.8 mm), outside diameter of 2.500 in (63.5 mm) and radial section of 0.250 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 405 lb; static radial capacity is 790 lb. The listed dynamic thrust capacity is 960 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.
