MODEL SELECTION & CROSS-REFERENCE

Selecting a KB025XP0 alternative.

Check the mounting envelope

KB025XP0 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

Four-point contact selection requires the combined radial, axial and overturning moment load case. Provide how these loads act together, along with speed, duty cycle and mounting stiffness, for an application review.

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 848 lb; static radial capacity is 1,140 lb. The listed dynamic thrust capacity is 1,290 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.

Send the complete KB025XP0 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 X configuration mean for selection?

Four-point contact selection requires the combined radial, axial and overturning moment load case. Provide how these loads act together, along with speed, duty cycle and mounting stiffness, for an application review. KB025XP0 is listed as type x · open · four-point contact.

What should I send for a KB025XP0 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.
