Product Description
The NTN 4T-LM11910 is a precision machined single-row tapered roller bearing cup, constructed of stamped steel, with a 1.7810-inch outside diameter and 0.4750-inch width. It serves as the outer race for paired bearing assemblies such as LM11949-LM11910, and delivers dynamic radial load ratings up to 2,280 lbf. Cross-reference applicability includes LM11910 and LM11949-LM11910 cup-cone sets. Specified for demanding manual pallet jack and industrial roller applications.

Frequently Asked Questions
Q: What are the outside diameter and width of the 4T-LM11910 bearing cup?
A: The 4T-LM11910 precision tapered roller bearing cup has an outside diameter of 1.7810 inches and a width of 0.4750 inches. These dimensions are engineered for manual pallet jack and industrial roller applications where space and load constraints require precision fitment.
Q: What is the dynamic radial load rating for the 4T-LM11910?
A: The 4T-LM11910 delivers a dynamic radial load rating of 2,280 lbf, supporting the load requirements of manual pallet jack steering and load wheel assemblies. This rating is based on one million revolutions to 90 percent bearing life.
Q: What cone assembly partners with the 4T-LM11910 cup?
A: The 4T-LM11910 cup pairs with the LM11949 cone to form the complete LM11949-LM11910 bearing set. Cross-reference part numbers include LM11949-90014. The cup-cone pairing is precision-matched and should not be separated.
Q: Why is stamped steel used in the 4T-LM11910 construction?
A: Stamped steel provides a balance of strength, weight reduction, and cost efficiency for manual pallet jack applications. The material is hardened to bearing-grade standards to resist spalling and wear in manual material handling equipment.
Q: Is the 4T-LM11910 suitable for both manual pallet jacks and industrial roller applications?
A: Yes, the 4T-LM11910 is designed for both manual pallet jack assemblies and industrial roller conveyors. The 2,280 lbf load rating and stamped steel construction support the demanding duty cycles of both applications.
