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, can also bear the radial load and axial load. When it only receives 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 high, especially in the axial load of high-speed
operation conditions, deep groove ball bearings than 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 become a series of
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 and other
industries, the machinery industry is the most widely used in a class of
bearings. Mainly bear radial load, but also can withstand a certain amount of axial load.
When
the larger radial clearance is selected, the axial load capacity
increases and the contact angle is zero when the pure radial force is
applied. When the axial force is applied, the contact angle is greater than zero. Generally used stamping wave type cage, car body cage, and sometimes also use nylon frame.
Deep
groove ball bearings mounted on the shaft, the axial clearance of the
bearing within the scope of the shaft or the shell can limit the axial
displacement in both directions, it can be bi-directional for axial
positioning. In
addition, the bearings also have a certain degree of 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.
