DAC Automative Air Conditioner Bearings  

Automotive Air Conditioner Bearings are double row angular contact ball bearings. Each Automotive Air Conditioner Bearings consists of one outer ring, one inner ring, rolling elements and cages. Especially, air conditioner bearing requires lower noise and stronger heat resistant specialty. Our Automotive Air Conditioner Bearings have been proved to be reliable quality through the usage of customers.

Automotive Wheel bearings
A wheel bearing is a simple device made up of two main components, the bearing itself and the race. The bearing itself consists of a metal housing that is pressed over a row of ball bearings that circle the metal housing. These ball bearings in turn ride on the race, which is a very smooth metal surface. When a wheel is rolling, the action of the ball bearings rolling against the surface of the hub that allows the wheel to spin smoothly. is the main purpose of bearing and to provide accurate guide to the rotation of the wheel hub, it is under axial load and radial load, is a very important component. It is  developed on the basis of standarded angular contact ball bearings and tapered roller bearings.
 
Characteristics
l Less energy consumption.
l Durable seals and couping life.
l Less vibration and noise.
l Super finished raceways.
 
Application
Widely used in car, vehicle, automobile cooling water pump, in textile machinery, engineering machinery, etc.
 
Series

Main Series

 Angular contact ball bearings has been designed to meet the increasingly demanding requirements of equipment manufacturers.  These bearings have a contact angle so that they can sustain significant axial loads in one direction together with radial loads.  Furthermore,  since an axial component is generated when a radial load is applied,  these bearings are generally used in pairs,  triplex sets,  quadruplex sets,  or multiplex sets.

Application Angular contact ball bearings are engineered for use in high-speed, high precision applications for:  Agriculture, Chemical, General industry, Utilities
