Industrial Roller Bearings

Rolling bearings are essential components in mechanical transmission systems. By replacing sliding contact with rolling contact, they enable low-friction motion between the shaft and its supporting structure. Their key advantages include a low friction coefficient, high load capacity, precise positioning accuracy, and exceptionally long service life—significantly reducing energy consumption and enhancing operational stability.

A bearing’s core structure consists of four main elements: the inner ring, which fits tightly onto the shaft and rotates with it; the outer ring, mounted in the housing to provide stable support; the rolling elements—such as cylindrical, tapered, or spherical rollers—positioned between the raceways to transmit loads and minimize friction; and the cage, which keeps the rolling elements evenly spaced to prevent collisions and ensure smooth, accurate movement. In certain applications, seals or lubrication systems may be added for enhanced protection and extended durability.

HSN supplies a complete range of cylindrical, tapered, and spherical roller bearings, with inner diameters from 10 mm to over 1000 mm—covering both general-purpose models and heavy-duty industrial types. With ample stock and strong customization capabilities, standard models can be shipped immediately, while drawings or sample-based customization is fully supported. All products undergo rigorous quality inspection. HSN bearings are fully compatible with domestic brands such as ZWZ and LYC, as well as international brands including SKF, FAG, Timken, and NTN, offering equivalent precision and installation compatibility, along with shorter lead times and superior cost performance.
