CL 203SF

Frequently Asked Questions

Q: What are the bearing dimensions of the CL 203SF?
A: The CL 203SF radial ball bearing has a 20 mm bore, 47 mm outside diameter, and 14 mm width. These dimensions are critical for fitment - verify your wheel assembly bore and OD match these specifications before ordering.

Q: What material is the CL 203SF bearing made from?
A: The CL 203SF is constructed from through-hardened chrome steel (SAE 52100 or EU equivalent). This material provides high load capacity and wear resistance needed for manual pallet jack load wheel applications in high-cycle warehouse operations.

Q: Does the CL 203SF come pre-lubricated?
A: Yes. The CL 203SF is pre-lubricated and equipped with dual synthetic rubber elastomer seals. This configuration extends bearing life under continuous warehouse use and requires minimal field maintenance.

Q: What is the seal configuration on the CL 203SF?
A: The CL 203SF features dual rubber seals made from synthetic rubber elastomer. These seals protect the bearing races and balls from dirt and contamination, which is essential for high-cycle warehouse operation where equipment is regularly exposed to floors with debris.

Q: What Clark pallet jack models use the CL 203SF bearing?
A: The CL 203SF is an OEM Clark radial ball bearing for manual pallet jack load wheels. It fits Clark branded pallet jacks. The alternate model designation is CL203SF. Verify your specific pallet jack model and wheel assembly dimensions before ordering to ensure fitment.

Q: When should the CL 203SF bearing be replaced?
A: Replace the CL 203SF when you observe increased noise, grinding, or vibration during wheel operation, visible corrosion on the outer race, or when wheels no longer roll freely under normal load. In high-cycle environments, monitor bearing condition regularly and plan replacement during scheduled maintenance cycles.
