Product Description

1. Product Overview

4T-LM503349/LM503310 follows NTN standard designation:

4T: NTN 4-Top series, case hardened steel (surface hardened, tough core, superior impact resistance)
LM503349 = inner cone assembly
LM503310 = outer cup, fully separable structure

Single row imperial tapered roller bearing, capable of carrying combined heavy radial load and unidirectional axial thrust. Normally installed in opposed paired arrangement to withstand bidirectional axial forces. Open design enables convenient disassembly, inspection and periodic re-lubrication. Widely fitted on vehicle wheel hubs, agricultural tractors, harvesting machinery, light construction equipment and medium-load reduction gear assemblies.

Formal quotation will be sent within 24 hours upon your inquiry.
