Understanding the 61902 RS 2RS Bearing Key Features and Applications

Bearings are critical components in numerous machinery and equipment, playing a pivotal role in reducing friction between moving parts. Among the various types of bearings available, the 61902 RS and 61902 2RS bearings hold significant importance due to their reliable performance and versatility. This article aims to delve into the intricacies of the 61902 RS and 2RS bearings, discussing their features, applications, and advantages.

What Are 61902 RS and 61902 2RS Bearings?

The numbers in the designation 61902 refer to the specific size and type of the bearing. The 6 indicates a deep groove ball bearing, a design known for its ability to accommodate radial loads and axial loads in both directions. The 1902 specifies the bearing's dimensions—specifically, an inner diameter of 15 mm, an outer diameter of 28 mm, and a width of 7 mm.

The suffixes RS and 2RS indicate the type of sealing on the bearing. RS means there is one rubber seal, while 2RS signifies that there are rubber seals on both sides of the bearing. This sealing mechanism provides enhanced protection against contaminants such as dust, dirt, and moisture, making these bearings suitable for a variety of environments.
