What is 6203lh bearing?

6203lh bearing is the most common type of rolling bearing. The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages.

6203lh bearing is mainly used to bear pure radial load, but also can bear radial load and axial load at the same time. When it only bears pure radial load, the contact angle is zero. When the 6203lh bearing has a larger radial clearance, it has the performance of an angular contact bearing and can withstand larger axial loads. The friction coefficient of 6203lh bearing is very small, and the limit speed is also very high, especially in the high-speed operating conditions with large axial loads, deep groove ball bearings are more superior than thrust ball bearings.

6203lh bearing has a simple structure and is easy to achieve higher manufacturing accuracy compared with other types. Therefore, it is convenient for mass production in series, and the manufacturing cost is lower, and its use is extremely common. In addition to the basic type, 6203lh bearing has various modified structures, such as: with dust cover; with rubber sealing ring; with stop groove.

6203lh bearing is the most representative rolling bearing with a wide range of uses. It is suitable for high-speed or even extremely high-speed operation, and it is very durable and does not require frequent maintenance. This type of bearing has low friction coefficient, high limit speed, simple structure, low manufacturing cost, and easy to achieve high manufacturing accuracy. Variety in size range and form, used in precision instruments, low-noise motors, automobiles, motorcycles and general machinery industries. It is the most widely used type of bearing in the machinery industry. Mainly bear radial load, but also can bear a certain amount of axial load.　When a larger radial clearance is selected, the axial bearing capacity will increase, and the contact angle will be zero when bearing pure radial force. When there is axial force, the contact angle is greater than zero. Generally, stamping wave-shaped cages, car-made solid cages, and sometimes nylon cages are used.

After the 6203lh bearing is installed on the shaft, within the axial clearance of the bearing, it can limit the axial displacement of the shaft or the housing in both directions, so it can be axially positioned in both directions. In addition, this type of bearing also has a certain degree of aligning ability. When it is inclined 2'-10' with respect to the housing hole, it can still work normally, but it will have a certain impact on the life of the bearing. Deep groove ball bearing cages are mostly stamped steel plate corrugated cages, and large bearings are mostly car-made metal solid cages.

6203lh bearing uses:
Used in gearboxes, instrumentation, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, etc. Metallurgical equipment, mining machinery, engineering machinery, papermaking equipment, wind power motors, semiconductors, machine tools, gear devices, motors, pumps and compressors, office equipment, injection molding machines, motorcycles, railways, etc.
