RA 850-139-349

Frequently Asked Questions

Q: What is a roller race and what does the RA 850-139-349 do?
A: The RA 850-139-349 is a roller race bearing component used in electric lift truck axle assemblies and load wheel systems. It provides support and smooth rotation for the axle shaft or wheel hub under load, a critical wear item in forklift drivetrain systems.

Q: What applications is the RA 850-139-349 designed for?
A: This roller race is an OEM Raymond part designed for electric lift truck axle or load wheel applications, including freezer warehouse and corrosion-resistant environments where standard roller races would degrade quickly.

Q: How does the RA 850-139-349 perform in freezer and corrosive environments?
A: The RA 850-139-349 is supplied with materials and finishes designed to resist freezer temperatures and corrosive conditions. This specialty construction extends bearing life compared to standard roller races in these harsh environments. Performance in cold storage and salt-exposed applications is significantly improved.

Q: What is the typical lifespan of this roller race bearing?
A: Roller race lifespan depends on load, speed, and operating environment. In typical electric forklift service, expect 2 to 5 years of reliable operation before wear becomes noticeable (increased vibration, loose play in axle, or grinding noise). Freezer and corrosive environments may reduce lifespan if the bearing seal is compromised.

Q: Are there cross-reference part numbers for the RA 850-139-349?
A: No approved cross-reference part numbers are currently available from authorized sources for the RA 850-139-349. Use the exact OEM part number when ordering to ensure you receive the freezer and corrosion-resistant variant.

Q: What is the part number format for the RA 850-139-349?
A: RA 850-139-349 is the standard OEM designation where RA denotes Raymond, followed by the unique part identifier. This format is used for ordering, inventory, and cross-reference lookups across material handling equipment systems.
