KG120AR0 is a Kaydon catalogue cross-reference for a PRIUS BEARINGS thin section alternative. Its reference envelope has a bore of 12.000 in, outside diameter of 14.000 in and radial section of 1.000 in. The listed configuration is Type A · Open · Angular contact.
Typical section drawing, not to scale. Match the dimension symbols to the model values below. Confirm fits, tolerances and manufacturing details against the approved model drawing.
A 12-inch angular-contact bore with a one-inch section
KG120AR0 has a 12.000 in bore, 14.000 in outside diameter and 1.000 in radial section. The equivalent nominal bore is 304.8 mm. A large hollow-shaft review needs the shoulder support and the opposing bearing arrangement as well as this envelope.
What to check in your assembly
Review L1 12.742 in, L2 13.258 in and counterbore L3 13.481 in against the mating shoulders.
Specify the axial load direction, pairing, preload or clearance and temperature range for the Type A arrangement.
Keep the 9.470 lb catalogue mass separate from load ratings, and include the handling and assembly access needed around the large bore.
Can another 12-inch-bore series replace KG120AR0?
Check the outside diameter and section as well as the bore. The contact arrangement, shoulder support and load ratings need a separate review when the series changes.
KG120AR0 belongs to the KG Series and has a bore of 12.000 in (304.8 mm), outside diameter of 14.000 in (355.6 mm) and radial section of 1.000 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 10,481 lb; static radial capacity is 24,640 lb. The listed dynamic thrust capacity is 25,780 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 KG120AR0?
Send the complete KG120AR0 reference, original drawing and required quantity. We review the 12.000 in bore, 14.000 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. KG120AR0 is listed as type a · open · angular contact.
What should I send for a KG120AR0 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. Original catalogue reference
