Understanding the 608 2RS Ball Bearing A Comprehensive Guide

Ball bearings play an essential role in modern machinery, providing the necessary support and reducing friction in moving parts. Among various types of ball bearings, the 608 2RS ball bearing is one of the most widely used due to its versatility and efficiency. In this article, we will delve into the specifications, applications, advantages, and maintenance of 608 2RS ball bearings.

Specifications of 608 2RS Ball Bearings

The designation 608 refers to the dimensions of the bearing. The first digit 6 indicates the series, while 08 represents the bore size in millimeters. Specifically, the 608 ball bearing has an inner diameter of 8 mm, an outer diameter of 22 mm, and a width of 7 mm. The 2RS in its name signifies the type of seals it has. In this case, it features two rubber seals on either side, providing a barrier against dirt, dust, and moisture while retaining lubrication inside the bearing.

The 608 2RS ball bearing typically uses chrome steel or stainless steel as its construction material, which offers excellent strength and durability. The bearings can comfortably operate within a temperature range of -30°C to +120°C, making them suitable for various environments.
