Deep Groove Ball Bearing

Bearing Category Details

Deep Groove Ball Bearings
Most representative of the rolling Bearing, Wide range of uses. Can bear radial load and bi-directional axial loads. Requirements for high-speed rotation and low noise, low vibration occasions. Strip Shield or rubber O-ring sealed type bearing a pre-filled with the right amount of grease, the outer ring with snap ring or flange bearing, that is easy to axial positioning, and easy to install inside the enclosure. Maximum load-type bearing the size of a standard bearing the same, but within the outer ring has a slot loading, an increase of the number of loading the ball to enhance the main application of the rated load cage, steel cage stamping (wave, crown-shaped ... separate; S shape ... double column)

Angular contact ball bearings
Between the ferrule and the ball contact angle, the standard contact angle of 15 , 30 and 40 , the contact angle the greater the greater the axial load capacity, the smaller the contact angle is more conducive to high-speed rotation. Single row bearings can bear radial load and a one-way axial load, DB combinations, DF composition and double row bearings can bear radial load and bi-directional axial load, DT-way combination for a larger axial load, a single bearing rated load lack of occasions. High-speed ball bearings with ACH diameter is small, the ball a few more, mostly for machine tool spindle; angular contact ball bearings for high-speed and high-precision rotation, the structure for the back of the combination of two single row angular contact ball bearing inner ring and outer ring sharing can bear radial load and bi-directional axial load, non-filling slot type bearings are also sealed.

Main use: medium and large motors, generators, internal combustion engines, gas turbine, machine tool spindles, deceleration devices, handling handling machinery, all kinds of industrial machinery.
Entity Type Needle Roller Bearing
The basic structure of a bearing inner ring and the NU type cylindrical roller bearings the same, but due to use of needle, the volume can be reduced, and can withstand large radial loads without bearing inner ring should have the appropriate accuracy and hardness of the shaft of the mounting surface as the raceway to use.
Mainly used to maintain frame: steel stamping cage.
Main use: car engines, transmissions, pumps, crawler excavators wheel, hoist, bridge cranes, compressors.
Tapered Roller Bearings
Type of bearing is equipped with truncated cone-shaped roller, roller guided by the inner ring large rib. The design makes the inner raceway, outer raceway and the roller rolling surface of the apex of the conical surface intersect at a point bearing center line.
Single row bearings can bear radial load and a one-way axial load, double row bearings can bear radial load and bi-directional axial loads.
Applies to withstand heavy load and shock load, according to chest contact () of the different divided into a small cone angle, the cone angle and large cone angle three kinds of type, the greater the contact angle the greater the axial load capacity. Outer and inner components (inner ring with roller and cage components) detachable, easy to Assembly and Disassembly, post-secondary, code-named "J" or "JR" bearing with international interchangeability. Type of bearing is also more use of British products.
Mainly used to maintain frame: steel stamping cage, synthetic resin forming cage, pin-type cage.
Main use: Automotive: front, rear, transmission, differential pinion shaft. Machine tool spindle, construction machinery, large-scale agricultural machinery, railway vehicles, gear equipment, rolling mill roll neck and deceleration devices.
Spherical Roller Bearings
Type of spherical bearings in the outer ring raceway and inner raceway fitted between pairs of spherical roller, according to the different internal structure, is divided into R, RH, RHA, and four kinds of type SR, because the outer ring raceway of circular arc center and bearing center line, with self-aligning properties, it can automatically adjust the shaft or housing deflection or a different axis errors caused by heart. Can bear radial load and bi-directional axial loads. In particular, the radial load capacity, suitable to withstand heavy load and shock load
Tapered bore bearings through the use of fasteners or a withdrawal sleeve allows the shaft of the Assembly and Disassembly.
There are two kinds of tapered bore (taper):
1:30 (Auxiliary code: K30) ... ... for 240,241 series.
1:12 (Auxiliary code: K) ... ... ... apply to other series.
