Frequently Asked Questions
Q: What are the specifications of the CL 654303 bearing?
A: The CL 654303 is a sealed deep groove ball bearing manufactured from chrome steel. Specifications: 20 mm bore diameter, 47 mm outer diameter, 14 mm width. Bearing races are SAE 52100 chrome steel with Rockwell C60 hardness on bearing components. Rolling elements are hardened steel.
Q: Which Clark manual pallet jack models use the CL 654303 bearing?
A: The CL 654303 is compatible with Clark manual pallet jack models requiring a sealed deep groove ball bearing with 20 mm bore and 47 mm outer diameter. The alternate model designation is CL654303. Verify your pallet jack hub specifications to confirm fitment.
Q: Why is the CL 654303 a sealed bearing?
A: The sealed design of the CL 654303 protects the bearing from contamination, dust, and water ingress during normal warehouse and dock operations. This extends bearing life and reduces maintenance by minimizing the need for frequent cleaning or lubrication.
Q: What is the material quality of the CL 654303?
A: The CL 654303 uses SAE 52100 chrome steel bearing races with a hardness specification of Rockwell C60 on bearing components. Hardened steel rolling elements provide durability for heavy-duty load wheel applications and meet industrial material handling performance standards.
Q: When should I replace the CL 654303 bearing?
A: Replace the CL 654303 when you detect noisy rotation, grinding sounds, increased friction in the wheel hub, or visible play in the load wheel. Sealed bearings cannot be repacked, so replacement is the appropriate maintenance action.
Q: Is the CL 654303 compatible with other brands?
A: The CL 654303 is an OEM Clark bearing. For cross-compatibility with Toyota, Raymond, Yale, Hyster, or other brands, verify that your equipment hub matches the 20 mm bore and 47 mm outer diameter specifications before ordering.
