Deep groove ball bearing
Product Name: Deep groove ball bearing
Product ID: 6000
Product Description: Deep groove ball bearings can be used in gearboxes, instrumentation, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, etc.
details:
  Deep Groove Ball Bearings are one of the most common types of rolling bearings. The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. The deep groove ball bearing type is code 6.

Deep groove ball bearings are mainly used to withstand pure radial loads and can also withstand radial and axial loads. When it is only subjected to a pure radial load, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can withstand a large axial load. The deep groove ball bearing has a small friction coefficient and a high limit speed. Especially in high-speed running conditions with large axial loads, deep groove ball bearings are superior to thrust ball bearings.
The deep groove ball bearing has a simple structure and is easy to achieve high manufacturing precision compared with other types, so it is easy to be mass-produced in series, and the manufacturing cost is also low, and the use is extremely common. In addition to the basic type, deep groove ball bearings also have various modified structures, such as: deep groove ball bearings with dust cover; deep groove ball bearings with rubber seals; deep groove ball bearings with snap grooves; Deep groove ball bearings with large load capacity of ball notches; double row deep groove ball bearings.
Deep groove ball bearings are the most representative rolling bearings and are widely used. Suitable for high speeds and even very high speeds, it is extremely durable and requires no maintenance. The bearing has small friction coefficient, high limit rotation speed, simple structure, low manufacturing cost and easy to achieve high manufacturing precision. Dimensional range and form are varied, and it is used in precision instruments, low noise motors, automobiles, motorcycles and general machinery. It is the most widely used type of bearing in the machinery industry. It is mainly subjected to radial loads and can also withstand a certain amount of axial load.
The axial load carrying capacity is increased when a larger radial clearance is selected, and the contact angle is zero when subjected to a pure radial force. When there is an axial force, the contact angle is greater than zero. Generally, a stamped wave cage is used, a solid cage is used, and a nylon frame is sometimes used.
After the deep groove ball bearing is mounted on the shaft, the axial displacement of the shaft or the casing can be restricted within the axial clearance of the bearing, so that the axial positioning can be performed in both directions. In addition, this type of bearing also has a certain ability to adjust the core. When it is inclined 2'~10' with respect to the hole of the housing, it can still work normally, but it has certain influence on the bearing life. Deep groove ball bearing cages are mostly steel plated wave cages, and large bearings are mostly made of metal body cages.
