Frequently Asked Questions
Q: What are the dimensions of the SC-4112 bearing assembly?
A: The SC-4112 features a 20 mm inner diameter, 47 mm outer diameter, and 14 mm overall width. These precision dimensions are critical for compatibility with manual pallet jack wheel assemblies. Verify these measurements against your equipment specifications before ordering.
Q: What manual pallet jack brands does the SC-4112 fit?
A: The SC-4112 bearing assembly supports both radial and axial loads in manual material handling equipment from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, and other major manufacturers. Confirm your model and serial number for exact compatibility.
Q: What are the construction details of the SC-4112?
A: The SC-4112 uses hardened high carbon steel inner and outer races (Rockwell C58-C65 hardness), through-hardened chromium steel balls, and a nylon reinforced polymer cage. Double rubber contact seals protect against contamination in warehouse and logistics environments.
Q: How does the SC-4112 seal design affect durability?
A: The double rubber contact seals minimize ingress of dust, water, and debris while maintaining grease retention. This design extends bearing life in continuous duty manual material handling applications. The polished finish with corrosion inhibitor provides additional protection against rust and oxidation.
Q: What is the load capacity and duty cycle of the SC-4112?
A: The SC-4112 is engineered for continuous duty load wheel and steering wheel support. Specific load ratings depend on your equipment configuration and total pallet jack capacity. Contact us with your equipment specifications for precise duty cycle and load capacity details.
