Product Introduction

The 27S/48KS is a highly versatile, compact tapered roller bearing set engineered to deliver robust load support within confined dimensional spaces. Measuring 27 x 48 x 14 mm, it is universally favored for light automotive hubs, motorcycle steering heads, and compact industrial gear assemblies. Operating from our advanced production center, we subject these compact components to the same rigorous quality assurance as our heavy-industrial lines. Utilizing high-precision grinding technology and strict tolerance monitoring, we ensure that every 27S cone perfectly interfaces with the 48KS cup. This meticulous engineering provides your distribution network with a smooth-running, highly durable bearing that eliminates vibration and ensures precise mechanical alignment.

Applications

Motorcycle and light utility vehicle steering stems and wheels.
Small automotive alternators and auxiliary equipment.
