MODEL SELECTION & CROSS-REFERENCE
Selecting a KB025AR0 alternative.
Check the mounting envelope
KB025AR0 belongs to the KB Series and has a bore of 2.500 in (63.5 mm), outside diameter of 3.125 in (79.375 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.
Review the contact and sealing arrangement
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.
Review the catalogue load data
The reference dynamic radial capacity is 675 lb; static radial capacity is 1,340 lb. The listed dynamic thrust capacity is 1,590 lb. These values describe the catalogue reference. Final PRIUS ratings, clearance and service life require confirmation against the application.
Compare references with the same nominal envelope
These references match bore, outside diameter and radial section. Contact geometry, land dimensions, sealing and ratings may differ; interchangeability needs a drawing review.
Can PRIUS supply an alternative for Kaydon KB025AR0?
Send the complete KB025AR0 reference, original drawing and required quantity. We review the 2.500 in bore, 3.125 in outside diameter, contact design, fits, clearance and load case before confirming a PRIUS alternative. Kaydon and Reali-Slim are original-owner trademarks used for cross-reference; PRIUS BEARINGS is an independent supplier.
What does the Type A configuration mean for selection?
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. KB025AR0 is listed as type a · open.
What should I send for a KB025AR0 quotation?
Send the model, quantity, shaft and housing dimensions, loads, speed, required clearance or preload, lubrication and operating environment. Email drawings or photos to sales@priusbearing.com. Include the original bearing suffix so the material and separator requirements can be checked.
Compare models with the same contact and sealing type, prioritising the same series, then nearby bore, outside diameter and section after unit conversion. Confirm fit and load ratings before substitution.
Specify the required material, separator, tolerance class, lubricant and operating temperature with your enquiry. Dimensions and load ratings are catalogue cross-reference data, not a guarantee of PRIUS product performance. Confirm the drawing, combined loads, clearance and application with our engineering team before ordering.
