BEARING assembly (SINGLE SHIELD)
Frequently Asked Questions
Q: What manual pallet jack models does the 3056752 bearing assembly fit?
A: The 3056752 single-shield bearing assembly is used in manual pallet jack load wheel assemblies, pump cylinders, and hydraulic valve bodies across Crown, Toyota, Yale, Jungheinrich, and Clark models. It supports both axle and pump spindle applications. Verify your specific jack model and year of manufacture before ordering to confirm fitment.
Q: What are the bore diameter and width specifications for the 3056752?
A: The 3056752 is a single-shield deep-groove ball bearing designed for load wheel and hydraulic spindle applications. The exact bore diameter, outer diameter, and width vary by application. Common sizes in manual pallet jack service are 17mm, 20mm, and 25mm bore diameters. Provide your jack serial number for precise dimensional specifications.
Q: What does single-shield design mean on the 3056752?
A: The single-shield design on the 3056752 means the bearing has a metal shield on one side only, protecting the bearing races and balls from gross contamination while allowing controlled grease access. This design is preferred in applications requiring periodic regreasing. The bearing is not sealed against water, so it requires maintenance in wet or cold storage environments.
Q: How long does the 3056752 bearing assembly typically last in manual pallet jack service?
A: Under normal warehouse operating conditions and with routine maintenance, the 3056752 bearing assembly typically lasts 3 to 5 years or 500,000 to 1,000,000 load cycles, whichever comes first. High-cycle operations and wet environments reduce lifespan. Replace the bearing immediately if noise, roughness, or axial play develops. Do not attempt to repack or repair failed bearings.
Q: Is the 3056752 suitable for cold storage pallet jacks?
A: The 3056752 single-shield bearing can operate in cold storage environments down to approximately minus 10 degrees Celsius if regreased with low-temperature grease formulations. Below that temperature, bearing stiffness increases and lubricant viscosity changes. For ultra-low temperature applications, specify cold-storage rated bearings. Consult us if your jack operates below minus 15 degrees Celsius.
Q: What are compatible cross-reference bearings for the 3056752?
A: The 3056752 is a direct replacement for equivalent single-shield bearings across Crown, Toyota, Yale, and Jungheinrich manual pallet jacks. OEM part numbers vary by manufacturer and application. We maintain cross-reference data and can confirm compatible SKUs. Provide your jack model and serial number for exact equivalents and sourcing alternatives.
