About Roller Bearing
Roller Bearings are precision-engineered mechanical components designed to carry heavy loads while minimizing friction between rotating parts. Unlike ball bearings that use spherical rolling elements, roller bearings use cylindrical, tapered, or spherical rollers to distribute loads over a larger surface area. This design results in higher load-carrying capacity, improved durability, and enhanced operational stability.
H K Sales is a trusted Roller Bearings supplier across Kolkata, West Bengal, Odisha, Bihar, Chhattisgarh, and Jharkhand, offering a comprehensive range of premium-quality bearings tailored for industrial, automotive, and engineering applications.
