APPLICATION & INTERCHANGE REVIEW

A sealed radial reference with a five-sixteenths-inch section

JB030CP0 uses a 3.000 in bore, 3.625 in outside diameter and 0.3125 in radial section. Its Type C configuration should be reviewed as a radial shaft support with the actual axial locating arrangement.

What to check in your assembly

Is JB030CP0 the same section as JA030CP0?

JB030CP0 has a 0.3125 in section, while the JA series uses 0.250 in. Review the outside diameter, land support and ratings for the chosen series.

MODEL SELECTION & CROSS-REFERENCE

Selecting a JB030CP0 alternative.

Check the mounting envelope

JB030CP0 belongs to the JB Series and has a bore of 3.000 in (76.2 mm), outside diameter of 3.625 in (92.075 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

Radial contact selection starts with the radial load and shaft support arrangement. If the assembly also needs axial location or moment resistance, include those loads for review before choosing the contact type.

This reference is sealed. Confirm the required seal material, lubricant and acceptable starting torque for your operating environment.

Review the catalogue load data

The reference dynamic radial capacity is 707 lb; static radial capacity is 1,340 lb. No dynamic thrust rating is listed for this reference. Send the axial load separately for engineering review. 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.

FREQUENT QUESTIONS

Can PRIUS supply an alternative for Kaydon JB030CP0?

Send the complete JB030CP0 reference, original drawing and required quantity. We review the 3.000 in bore, 3.625 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 C configuration mean for selection?

Radial contact selection starts with the radial load and shaft support arrangement. If the assembly also needs axial location or moment resistance, include those loads for review before choosing the contact type. JB030CP0 is listed as type c · sealed · radial contact.

What should I send for a JB030CP0 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.
