Deep Groove Ball Bearings Mainly used to bear
Deep Groove Ball Bearings are the most common type of rolling bearing. The basic type of deep groove ball bearings consists of an outer ring, an inner ring, a group of steel balls and a set of cage, deep groove ball bearing type code 6.
Deep groove ball bearings are mainly used to withstand the pure radial load, but also can bear the radial load and axial load. When it is only subjected to a pure radial load, the contact angle is zero. When the deep groove ball bearings have a large radial clearance, with angular contact bearing performance, can withstand greater axial load. Deep groove ball bearing friction coefficient is very small, the limit speed is also very high, especially in the axial load of high-speed operation conditions, the deep groove ball bearings than the thrust ball bearings more advantages.
Deep groove ball bearing structure is simple, compared with other types easy to achieve high manufacturing accuracy, so easy to series into mass production, manufacturing costs are low, the use of very common. Deep groove ball bearings in addition to the basic type, there are a variety of variant structure, such as: with dust cover deep groove ball bearings; rubber seals with deep groove ball bearings; groove groove groove ball bearings; Ball gap of the large load capacity of the deep groove ball bearings; double row deep groove ball bearings.
Deep groove ball bearings are the most representative of the rolling bearings, widely used. Suitable for high speed or even high speed operation, and very durable, without regular maintenance. The bearing friction coefficient is small, the limit speed is high, the structure is simple, the manufacturing cost is low, and it is easy to achieve high manufacturing precision. Size range and form of diverse, used in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries, the machinery industry is the most widely used in a class of bearings. Mainly to bear the radial load, but also can withstand a certain amount of axial load.
When the larger radial clearance is selected, the axial load capacity is increased and the contact angle is zero when the pure radial force is applied. With axial force, the contact angle is greater than zero. Generally used stamping wave type cage, car system solid cage, and sometimes also use nylon frame.
Deep groove ball bearings mounted on the shaft, the axial clearance in the bearing within the scope of the shaft or shell can limit the axial displacement of the two directions, so the two-way for axial positioning. In addition, this type of bearing also has a certain self-aligning ability, when relative to the shell hole inclined 2 '~ 10', still work, but the bearing life has a certain impact. Deep groove ball bearing cage for steel plate stamping wave type cage, large bearings and more use of metal metal body cage.
