Speed and maximum no-load torque are original catalogue reference values under the stated seal, lubrication and test conditions. Confirm operating speed, starting torque, lubricant and temperature for the final PRIUS drawing.
APPLICATION & INTERCHANGE REVIEW
JA045XP0 combines a 4.500 in bore, 5.000 in outside diameter and 0.250 in radial section. Its Type X geometry calls for a combined radial, axial and overturning-moment load case; the three load ratings should not be added together as independent allowable loads.
JA045XP0 has a 4.500 in bore and 0.250 in section; JU042XP0 has a 4.250 in bore and 0.375 in section. The shaft interface and contact dimensions differ.
MODEL SELECTION & CROSS-REFERENCE
JA045XP0 belongs to the JA Series and has a bore of 4.500 in (114.3 mm), outside diameter of 5.000 in (127 mm) and radial section of 0.25 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.
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 sealed. Confirm the required seal material, lubricant and acceptable starting torque for your operating environment.
The reference dynamic radial capacity is 809 lb; static radial capacity is 1,440 lb. The listed dynamic thrust capacity is 1,310 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.
FREQUENT QUESTIONS
