What is a Roller bearing?

Roller Bearings are mechanical components used to support rotating shafts or axles, minimizing friction and enabling efficient rotation. Unlike ball bearings, roller bearings use rollers (such as cylindrical, tapered, or spherical shapes) between the inner and outer races, which allows them to carry higher loads. This design provides better load-bearing capacity than ball bearings.

Structure and Function:
Roller bearings consist of an outer race, an inner race, and multiple rollers placed between them. The rollers help support the rotating motion and reduce friction between the moving parts, enabling smooth rotation. Roller bearings are often used in applications that involve high loads or relatively low rotational speeds.

Features:
・High load capacity: Roller bearings can withstand higher loads compared to ball bearings.
・Low friction: The larger contact area between the rollers and races reduces friction and increases efficiency.
・Durability: They have a longer service life due to reduced wear.
・Variety of types: Roller bearings come in various forms, including cylindrical, tapered, and spherical roller designs.

Application of Roller bearing

１．Automotive wheel bearings: Used in vehicle wheels to allow smooth rotation while supporting the weight of the vehicle.
２．Industrial machinery: Used in heavy-duty machinery and equipment that require high load-bearing capacity.
３．Power tools: Roller bearings are often found in power tools to support the rotating shafts and ensure smooth operation.
