RA 441-009

Frequently Asked Questions

Q: What material is the RA 441-009 bearing made from?
A: The RA 441-009 is manufactured from SAE 52100 bearing steel, a high-carbon alloy steel that provides superior hardness, wear resistance, and load-carrying capacity for electric lift truck applications.

Q: What seal type does the RA 441-009 have?
A: The RA 441-009 is a double-sealed precision ball bearing with synthetic rubber seals (nitrile-NBR blend). The dual seals provide contamination resistance and retain factory pre-applied lubrication during storage and operation.

Q: What is required to install the RA 441-009 in a Raymond forklift hub?
A: The RA 441-009 is designed for press-fit installation into Raymond forklift hubs and housings. The bearing bore dimensions must be verified to match the hub specifications before installation.

Q: Is the RA 441-009 pre-lubricated?
A: Yes, the RA 441-009 is factory pre-lubricated. The bearing requires no additional lubrication before installation and is ready for immediate use upon receipt.

Q: What is the lifespan of the RA 441-009 double-sealed bearing?
A: The RA 441-009 lifespan is contingent on load, speed, cleanliness, and lubrication maintenance. The double-sealed design extends service life compared to open bearings by protecting against water, dust, and debris ingress in warehouse and material handling environments.

Q: How do I detect when the RA 441-009 seals have degraded?
A: Inspect for visible cracks or deterioration in the synthetic rubber seals, bearing roughness during rotation, or noise during equipment operation. If seals are compromised, contamination will accelerate bearing wear and replacement is required.
