Frequently Asked Questions

Q: What type of bearing is CK 902654 and what are its bore and outer diameters?
A: The CK 902654 is a deep groove ball bearing commonly used in manual pallet jack wheel and axle assemblies. The exact bore diameter, outer diameter, and width depend on the specific bearing specification. Contact technical support with the bearing specification or your equipment model to confirm dimensions before ordering.

Q: Which manual pallet jack models use the CK 902654 bearing?
A: This bearing is compatible with manual pallet jack load wheel and steering wheel assemblies from multiple OEM manufacturers. Confirm compatibility by matching your pallet jack model number and wheel configuration to the bearing specification sheet, as bearing applications vary across different load wheel types and axle designs.

Q: What is the load rating and operational speed limit for CK 902654?
A: Load ratings and maximum RPM specifications for the CK 902654 depend on bearing size and internal clearance class. Typical manual pallet jack bearings handle static loads of 1,000 to 5,000 pounds with maximum rotational speeds under 300 RPM. Verify exact load and speed ratings from the bearing specification or equipment documentation.

Q: What material and seal type is the CK 902654 bearing?
A: The CK 902654 bearing uses chrome steel races and balls, standard for material handling applications. Confirm whether the bearing has open design, rubber seals, or metal shields by checking the part specification, as different seal configurations provide varying protection from moisture and contamination in warehouse environments.

Q: How long does the CK 902654 bearing typically last in normal warehouse use?
A: Bearing lifespan in manual pallet jacks ranges from 2 to 5 years depending on load frequency, maintenance, and environmental conditions. Bearings operating on wet or corrosive surfaces may fail sooner. Monitor for rough rotation, grinding sounds, or excess play in the wheel; these indicate bearing wear and replacement need.

Q: Are there equivalent cross-reference part numbers for CK 902654?
A: Cross-reference equivalencies depend on the exact bearing size and specification. Common manual pallet jack bearing suppliers include SKF, Timken, and NSK; your specific bearing may have multiple equivalent numbers. Contact technical support with the bearing dimension to identify compatible alternatives.
