Frequently Asked Questions
Q: What are the specifications for the 2I5937 thrust bearing?
A: The 2I5937 is a thrust bearing with 25 mm inner diameter (ID), 52 mm outer diameter (OD), and 15 mm width. It is constructed from high carbon chrome steel (SAE 52100) with a pressed steel cage. Dynamic load capacity is 23.2 kN and static load capacity is 45.8 kN. Cross-references include part numbers 51205 and 120E4.
Q: Which manual pallet jack assemblies use the 2I5937 thrust bearing?
A: The 2I5937 fits standard manual pallet jack assemblies from Crown, Toyota, Raymond, Yale, Hyster, and similar manufacturers using this bearing size and load rating. The cross-reference numbers 51205 and 120E4 can help identify compatible equipment. Verify dimensions match your equipment before ordering.
Q: Why is high carbon chrome steel used in the 2I5937 bearing?
A: High carbon chrome steel (SAE 52100) provides superior hardness, wear resistance, and load-carrying capacity required for thrust bearing applications. This material maintains its strength under continuous hydraulic and load support stress in warehouse pallet jacks while resisting fatigue failure.
Q: Is the 2I5937 bearing factory-lubricated and what is its maintenance requirement?
A: Yes, the 2I5937 is factory-lubricated and designed for continuous operation without additional lubrication during normal use. Inspect periodically for wear or contamination. If the bearing becomes noisy or exhibits rough operation, replacement is recommended rather than re-lubrication.
Q: What load conditions is the 2I5937 thrust bearing rated for?
A: The 2I5937 has a dynamic load capacity of 23.2 kN for continuous rotating applications and a static load capacity of 45.8 kN for stationary loads. These ratings support the hydraulic and load-carrying requirements of manual pallet jack assemblies in typical warehouse operations. Do not exceed rated load capacity.
