Understanding the 6808 ZZ Bearing An Essential Component in Modern Machinery

In the world of engineering and mechanics, bearings play a crucial role in ensuring smooth operation and longevity of machinery. One such type, the 6808 ZZ bearing, is widely used across various applications due to its unique design and functional benefits. This article explores the features, specifications, applications, and advantages of the 6808 ZZ bearing, shedding light on why it’s become a popular choice for many engineers and manufacturers.

What is a 6808 ZZ Bearing?

The designation 6808 refers to the specific size and series of the bearing. The first two digits (68) indicate the series, while the last two digits (08) specify the inner diameter. The ZZ suffix denotes that the bearing is equipped with metal shields on both sides, which helps protect against dust, dirt, and moisture, thereby enhancing the bearing’s longevity and reliability.

Typically, the 6808 ZZ bearing has an inner diameter of 40 mm, an outer diameter of 52 mm, and a width of 7 mm. This compact size makes it suitable for applications where space is limited but where robust performance is still required. The bearing is usually made from high-quality steel, providing excellent wear resistance and durability even under challenging operating conditions.
