Product Introduction

The 48Y/25YM is a precise, compact tapered roller bearing assembly designed to provide high load capacity within tight dimensional constraints. With dimensions of 25 x 48 x 13 mm (Bore: 25mm, Outer Diameter: 48mm, Width: 13mm), it is an essential component for automotive gearboxes, steering columns, and compact industrial drives. Manufactured in our modern automated facility, the 48Y/25YM features precision-ground raceways that ensure low friction, quiet operation, and minimal heat generation. Through our strict enterprise quality assurance, every 25YM cup and 48Y cone assembly delivers exact alignment and smooth, vibration-free rotation.

Applications

Automotive steering stems, gearboxes, and transfer cases.
Light utility vehicle wheel hubs and driveshaft supports.
Compact industrial speed reducers and power tools.
