Description
Deep groove ball bearing is the most common type in rolling bearing. It is usually composed of a outer ring, a inner ring, a row of steel balls and cage. It mainly bears radial loads, but it can also bear a small amount of axial loads. Axial carrying capacity will increase when selecting large radial clearance. The contact angle is zero when bear only radial force; The contact angle will more than zero when axial force is acted.
Cage
Usually use the stamping wave-shaped cage and solid cage, nylon cage used sometimes
Features
Low friction, high limiting speed, simple structure, cost saving
Application
Gearbox, instruments, motor, household appliances, internal-combustion engine, transport vehicles, agricultural machinery, construction machinery and engineering machinery, etc

1. Introduction to Kaydon thin section bearings
LYHY bearings are a professional manufacturer of substitution of imported brand thin section bearings, which includes seven open series and five sealed series, inner hole diameter of these  slim ball bearings range from 1 to 40 inches, cross-sectional dimension is from 0.1875X0.1875 to 1.000X1.000. These ball bearings have an extremely small, predominantly square cross-section, within each series, the cross-section remains constant even for larger shaft diameters and housing bores. Except the standard models, we can also design and manufacture as per customers' requirements. With rich experience and a large collection of products, we have confidence we are able to meet customers' requirements.

Open type  angular contact bearing 
Open type  four point contact bearing
Sealed type deep groove ball bearing
Sealed  four point contact ball bearing

 

3. Features
Thin section bearings have high precision, and very quiet and have high load carrying capacity, features of thin section bearings can be summarized as following
Excellent running accuracy
Spaces save
Low friction
High precision
Long life
Low noise and vibration

 

4. Application
Thin section ball bearings were developed for applications where space limitations are of the utmost importance. These kind of bearings are widely used for aviation, astronomical instruments, glass manufacturing machinery, medical instrument, optical and scanning instrument, satellite communication devices, textile machinery, large welding equipment, robot, semiconductor manufacturing equipment etc.print machinery
