Deep Groove Ball Bearing

eep groove ball bearings or single row radial ball bearings, are the most common type of rolling bearings. Their use is very widespread. It usually consist of a pair of rings, a retainer, a single row of steel balls. The two races are grooved or shaped on their inner surfaces to accept and retain the balls, Single Row Deep Groove Ball Bearings have the highest speed capacity of all rolling element bearings, Deep groove ball bearing is mainly used to bear radial load and operating at relatively high speeds, but it can also bear a certain amount of axial load in either direction.

Feature:

Compared with other bearings, deep groove ball bearing has smaller friction coefficient and higher limiting rotate speed, it is more durable and universal with low noise and is easier to install. Deep groove ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races.

Since sliding cannot be eliminated in the contacts between the cage and other bearing parts, the cage itself is the first component to be affected when lubrication becomes inadequate. Our ball bearings use unique design polyamide and steel cage, The inner/outer rings and  Retainer(cage) are thicker compare with the Common bearings, stronger rivet, which consist more reliable structure. strong impact and heavy load with Grinding groove and super finishing technology. to offer the long life under extreme harsh environment.

Clearance:

Deep groove ball bearings have internal clearance. This provides the bearing room for expansion between the bearing races and will add a small amount of play between the two rings. Large clearance C3/C4 usually used in harsh environment. with good anti-seize performance used in particularly harsh environment.

Tolerances

The standard version of our single-row deep groove ball bearings has the tolerance class P0

(designs with tighter tolerances available upon request)

Types:

1. Classified according to sealed type:

Open type: Open type deep groove bearings are manufactured without seals to allow for the free circulation of either oil or grease, cost effective solution

Shielded type: With one shield (-Z) on one side or two shields (-2Z/ZZ) on both sides; Shielded bearings are provided with non-contacting metal shields that protect against larger particles entering the bearing, but do not protect against liquids. They add no friction during operation and therefore do not generate heat build-up.

Sealed type: With one seal (-RS) on one side or two seals (-2RS) on both sides. Sealed bearings are supplied with a contacting lip seal that excels in protecting the bearing from liquids and other foreign contaminants. The inherent design creates friction, drag, and in turn heat; factors that require consideration in high speed applications.

2.  Classified according to the Retainer/Cage:

Nylon cage deep groove ball bearing: Our KA(Nylon retainer) series bearings Obtained MA certification of China Coal Research Institute, safety certificate of approval for mining products (rollers) in China, with good performance of anti-seize and anti-static.

Steel cage deep groove ball bearing:  Thicker cage with stronger rivet, which consist more reliable structure.
