What Are Ball Bearings Used For？Single row angular contact ball bearings main uses: machine tool spindles, high frequency motors, gas turbines, centrifugal separators, small car front wheels, differential pinion shafts, booster pumps, drilling platforms, food machinery, indexing heads, welding machines, low-noise cooling towers, electromechanical equipment, painting equipment, machine tool slot plates, arc welding machines
Double-row angular contact ball bearings: oil pumps, Roots blowers, air compressors, various types of transmissions, fuel injection pumps, printing machinery, planetary reducers, extraction equipment, cycloidal reducers, food packaging machinery, welding machines, soldering irons, square boxes, gravity guns, wire strippers, half shafts, inspection and analysis equipment, fine chemical machinery
1. contact angle between the collar and the ball, the standard contact angle is 15°, 30° and 40°.
2, the greater the contact angle axial load capacity is also greater.
3, the smaller the contact angle, the more conducive to high-speed rotation.
4, single row bearing can bear radial load and one-way axial load.
5, DB combination, DF combination and double row bearing can bear radial load and two-way axial load.
6, DT combination for one-way axial load is large, a single bearing load rating is not enough for the occasion.
7, high speed with ACH bearing ball diameter is small, the number of balls, mostly used in machine tool spindles.
8、Angular contact ball bearings are suitable for high speed and high precision rotation.
9, structure for the back of the combination of two single row angular contact ball bearing common inner ring and outer ring, can withstand radial negative
load and two-way axial load.
10, no filling groove bearings also have sealed type. The main applicable keep frame.
Steel plate stamping keep frame (bowl – single row; S-shaped, crown – double row), copper alloy or phenolic resin cutting keep frame, synthetic resin forming keep frame.
1、Because the outer ring raceway surface is spherical, it has the performance of aligning, so it can automatically adjust the shaft or shell deflection or different heart caused by shaft misalignment.
2、Tapered hole bearings can be easily mounted on the shaft by using fasteners. Steel plate stamping cage: daisy-shaped – 12, 13, 22 – 2RS, 23 – 2RS Kwai-shaped – 22, 23.
Woodworking machinery, textile machinery drive shafts, vertical spherical bearings with seats.
1、Can withstand radial load and two-way axial load.
2, a single bearing can replace the front combination or back combination of angular contact ball bearing; 3, suitable for bearing pure axial load or axial load component of a larger synthetic load; 4, the bearing with any direction of the axial load can form one of the contact angle (a), so the collar and the ball always in any contact line of the two sides of the three knife point contact.
copper alloy cut cage.
aircraft jet engine, combustion turbine.
