Frequently Asked Questions
Q: What are the dimensions of the 1049915 bearing assembly?
A: The 1049915 is a precision sealed ball bearing with the following dimensions: 20 mm bore, 47 mm outer diameter, and 14 mm width. These dimensions are specified for SAE 52100 high-carbon chrome steel construction with C3 internal clearance.
Q: What load capacity does the 1049915 support?
A: The 1049915 bearing assembly is compatible with manual pallet jacks rated up to 5,500 lbs. The bearing is engineered for intermittent rotation speeds up to 300 RPM and is suitable for applications with repeated acceleration and load cycles typical of warehouse material handling.
Q: What material is the 1049915 bearing made from?
A: The 1049915 is manufactured from SAE 52100 high-carbon chrome steel. The inner and outer races are hardened to Rockwell C58 through C65 hardness, providing superior wear resistance and durability for high-cycle warehouse applications.
Q: Is the 1049915 pre-lubricated?
A: Yes, the 1049915 bearing assembly is factory-lubricated with NLGI Grade 2 lithium complex grease. The sealed design contains the lubricant and protects internal ball and raceway components from contamination and moisture ingress.
Q: How long does the 1049915 bearing typically last in warehouse service?
A: Bearing lifespan depends on load conditions, cycle frequency, and maintenance environment. The SAE 52100 steel construction and factory lubrication support extended service in typical warehouse conditions. Inspect bearings periodically for noise, roughness, or play indicating wear and replacement need.
Q: Which pallet jack models does the 1049915 fit?
A: The 1049915 bearing assembly is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, and other standard manufacturers. Verify your equipment bore size is 20 mm and outer diameter is 47 mm before ordering to confirm proper fitment.
