PR 25-73

Frequently Asked Questions

Q: What equipment does the PR 25-73 bearing fit?
A: The PR 25-73 is a 73-B Series single-row radial ball bearing designed for electric lift truck applications. It is compatible with multiple OEM brands including Crown, Toyota, and Raymond electric lift trucks. Verify that your equipment uses a 73-B Series bearing configuration before ordering.

Q: What material is the PR 25-73 constructed from?
A: The PR 25-73 is constructed from high carbon chromium bearing steel, hardened to Rockwell C60 minimum on the raceways. This material provides durability and wear resistance in heavy-duty electric lift truck duty. The bearing features polished surfaces and a steel ball and cage assembly with solid inner and outer rings.

Q: What does Class 6 precision mean for this bearing?
A: Class 6 precision refers to the bearing tolerance and runout specification. This classification ensures tight dimensional tolerances, which provides smooth operation, reduces vibration, and improves load distribution in electric lift truck applications. Class 6 bearings are suitable for general industrial material handling equipment.

Q: When should the PR 25-73 bearing be replaced?
A: Replace the bearing if you experience excessive noise, vibration, grinding, or resistance during load wheel rotation. Bearing failure symptoms include increased friction during lift operations, abnormal heat generation at the bearing housing, or visible damage to the raceway surfaces. Bearing replacement is typically performed when load wheel assemblies reach end-of-life.

Q: Are cross-reference part numbers available for the PR 25-73?
A: No cross-reference part numbers are currently available for the PR 25-73. This is an OEM-specific bearing. Verify the exact part number from your equipment documentation before ordering to ensure compatibility.
