4T-LM503349/LM503310 is an inch-size single row tapered roller bearing, made up of separable cone assembly LM503349 and outer cup LM503310. Made of GCr15 chrome bearing steel, this open bearing handles combined radial and unidirectional axial loads. Its separable design supports simple mounting and clearance adjustment, while the stamped steel cage keeps rollers aligned steadily. It works reliably under medium load conditions and is widely used for automotive hub and machinery transmission replacement.
