Frequently Asked Questions
Q: What are the dimensions and specifications of the CK2779844 sealed bearing?
A: The CK2779844 is a sealed ball bearing assembly with a 20 mm bore, 47 mm outer diameter, and 14 mm width. It features stainless steel races, chrome steel balls, and synthetic rubber seals. This bearing is rated for high-duty industrial applications including washdown environments.
Q: Which material handling equipment does the CK2779844 bearing fit?
A: The CK2779844 is designed for load wheels, steering wheels, and casters on manual pallet jacks and hand carts from common OEM brands. Before ordering, verify that the 20 mm bore and 47 mm OD match your specific equipment wheel assembly dimensions.
Q: Why choose a sealed bearing like the CK2779844 for washdown environments?
A: The synthetic rubber seals on the CK2779844 provide contamination resistance in washdown and wet floor applications. The stainless steel races and chrome steel balls resist corrosion, reducing friction loss and extending bearing lifespan compared to unsealed alternatives in harsh environments.
Q: How long does the CK2779844 bearing typically last in normal material handling use?
A: Sealed bearing lifespan depends on load, hours of operation, and environmental conditions. In typical warehouse and loading dock applications with regular equipment maintenance, sealed bearings like the CK2779844 generally perform for 12 to 24 months before replacement. High-moisture or extreme-duty environments may shorten this interval.
Q: What maintenance does the CK2779844 sealed bearing require?
A: Sealed bearings require minimal maintenance. Periodic visual inspection for damage, seal deterioration, or contamination is recommended. The sealed design prevents re-lubrication and protects internal components, making field maintenance unnecessary under normal operating conditions.
