Ha axis - Introduction to deep groove ball bearings

HRB bearing - Deep groove ball bearing is the most common type of rolling bearing. The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls, and a set of retaining structures. There are two types of deep groove ball bearings: single row and double row. The deep groove ball structure is also divided into sealed and open types. Open type refers to bearings without a sealed structure, while sealed deep groove balls are divided into dust-proof and oil proof seals. The dustproof sealing cover material is stamped steel plate, which only plays a simple role in preventing dust from entering the bearing raceway. The oil proof type is a contact type oil seal, which can effectively prevent the lubricating grease inside the bearing from overflowing.
The type code for single row deep groove ball bearings is 6, and the code for double row deep groove ball bearings is 4. Its structure is simple and easy to use, making it the most commonly produced and widely used type of bearing.

1、 Bearing structure:Composed of an inner ring, an outer ring, a retainer, and a set of steel balls;

2、 Bearing characteristics:

2.1 Deep groove ball bearings have a low friction coefficient, high maximum speed, simple structure, low manufacturing cost, and are easy to achieve high manufacturing accuracy;
2.2 The size range and form variations are diverse, and are applied in industries such as precision instruments, low-noise motors, automobiles, motorcycles, and general machinery;
2.3 It mainly bears radial loads and can also withstand a certain amount of axial loads.
2.4 Generally, stamped wave shaped retaining frames, vehicle made solid retaining frames, and sometimes nylon frames are also used.
2.5 Deep groove ball bearings have a certain degree of self-aligning ability, and can still work normally when tilted 2 'to 10' relative to the housing hole, but it has a certain impact on the bearing life.
2.6 Deep groove ball bearing retainers are mostly steel plate stamped wave shaped retainers, while large bearings often use machine-made metal solid retainers.
2.7 Its structure is simple and easy to use.
2.8 Users should be reminded that deep groove ball bearings are not resistant to impact and are not suitable for withstanding heavy loads.

3、 Ha axis - Size range of commonly used models of deep groove ball bearings

Inner diameter size range: 10mm~1320mm
Outer diameter size range: 30mm~1600mm
Width dimension range: 9mm to 300mm

4、 Application of Ha axis deep groove ball bearings:

HRB bearings - deep groove ball bearings can be used in industries such as fans, motors, machine tools, cement plants, power plants, transmissions, instruments, motors, household appliances, internal combustion engines, transportation vehicles, textile machinery, agricultural machinery, construction machinery, engineering machinery, etc.
