10452-62037

Frequently Asked Questions

Q: What are the specifications of the 10452-62037 bearing assembly?
A: The 10452-62037 bearing assembly has a 20 mm bore, 47 mm outside diameter, and features precision sealed chrome steel ball bearing construction with dual contact rubber seals. These dimensions fit standard manual pallet jack hydraulic pump applications.

Q: What equipment does the 10452-62037 bearing fit?
A: The 10452-62037 is designed for the hydraulic pump assembly on manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and similar manufacturers. Verify your pallet jack model and pump specifications match the 20 mm bore and 47 mm OD dimensions.

Q: What do the dual contact rubber seals do on the 10452-62037?
A: The dual contact rubber seals prevent hydraulic fluid, dirt, and moisture from entering the bearing races. These seals maximize bearing lifespan by maintaining internal lubrication and protecting steel surfaces from corrosion and contamination.

Q: How long does the 10452-62037 bearing assembly last?
A: Under normal manual pallet jack use, this bearing typically lasts 3-5 years. Heavy-duty or high-cycle operations may reduce lifespan. Replace the bearing if you hear grinding, feel rough rotation at the pump, or notice reduced lift pressure.

Q: What material is the 10452-62037 bearing made from?
A: The 10452-62037 uses chrome steel ball bearing construction, which provides superior hardness, wear resistance, and corrosion resistance compared to standard steel. Chrome steel is ideal for sealed hydraulic pump bearings in manual material handling equipment.

Q: What symptoms indicate the 10452-62037 bearing needs replacement?
A: Replace the bearing if the hydraulic pump makes grinding or squealing noise, the pump becomes difficult to operate, lift pressure drops suddenly, or the bearing feels rough when rotated by hand. Continued use of a failing bearing will damage the pump assembly.
