Frequently Asked Questions
Q: What equipment types use bearing assembly 3737073?
A: Bearing assembly 3737073 is used in electric pallet jacks and ride-on material handling vehicles from Crown, Raymond, Jungheinrich, and Toyota. This bearing is designed for higher-speed operation compared to manual jack bearings and supports dynamic loading in electric lift applications.
Q: What is the bore size and outer diameter of bearing assembly 3737073?
A: Bearing assembly 3737073 has a 1.5 inch bore diameter and 2.875 inch outer diameter with a 0.875 inch width. These dimensions are standard for mid-sized load wheels on electric material handling equipment.
Q: Does bearing assembly 3737073 have sealed protection?
A: Yes, bearing assembly 3737073 features double-sealed construction with nitrile rubber contact seals. The sealed cartridge design protects against water ingress, dust, and debris typical in dock and cold storage environments.
Q: How long does bearing assembly 3737073 typically last?
A: Bearing assembly 3737073 has an expected service life of 3000 to 8000 operating hours under normal load conditions on electric pallet jacks. Cold storage or wet environments may reduce this lifespan by 20 to 30 percent.
Q: What symptoms indicate bearing assembly 3737073 needs replacement?
A: Replace bearing assembly 3737073 if you experience grinding or squealing from the load wheel, excessive side-to-side movement of the wheel, or notchy rotation resistance. Heat buildup around the bearing cartridge is also an indicator of wear.
Q: Is bearing assembly 3737073 suitable for freezer and cold storage use?
A: Bearing assembly 3737073 is rated for cold storage operation down to minus 10 degrees Fahrenheit. Use this bearing in freezer applications, but plan for more frequent replacement due to lubricant viscosity changes and seal material brittleness in prolonged cold.
