Frequently Asked Questions
Q: What are the bore diameter and cone width specifications for the 4T-L44649?
A: The 4T-L44649 tapered roller bearing cone features a 1.0625 inch bore diameter and 0.58 inch cone width. It is manufactured from bearing-grade alloy steel and pairs with the L44610 cup.
Q: What dynamic load ratings does the 4T-L44649 bearing cone support?
A: The 4T-L44649 provides a dynamic radial load rating of 1,750 lbf at c90 life and 6,760 lbf at c1 life. It supports high-speed applications up to 7,500 RPM, making it suitable for manual pallet jack assemblies under continuous duty.
Q: What are the cross-reference and equivalent part numbers for this bearing cone?
A: The 4T-L44649 cross-references to Timken SET4, SKF BR4, and WJB WTA4. Equivalent part numbers include L44649, L44649-9X062, and KL44649. Verify dimension and load rating compatibility with your equipment before ordering.
Q: Which pallet jack applications is the 4T-L44649 bearing cone compatible with?
A: The 4T-L44649 is designed for manual pallet jack steering and load wheel assemblies. It is compatible with L44610 cup assemblies and provides the load capacity required for manual material handling equipment in standard warehouse and production environments.
Q: How does bearing-grade alloy steel affect the durability of the 4T-L44649?
A: Bearing-grade alloy steel provides superior hardness, fatigue resistance, and wear properties compared to standard steel. This material resists spalling and extends bearing life in high-load and high-speed applications typical of manual pallet jack use.
