Self-aligning ball bearings of the basic types of features and uses:
Self-aligning ball bearings
Self-aligning ball bearings allow the shaft to be deflected around the
center of the bearing by 4 ° and the sealed self-aligning ball bearings
can compensate for a maximum of 1.5 °.
1. To adapt to the error situation
Self-aligning ball bearings better adapt to self-lubricating compound bushing misalignment conditions than any other bearing. That can make the case of shaking, the bearing can still run smoothly.
2 excellent high-speed performance
F
& F Self-aligning ball bearings have the lowest copper-based
self-lubricating plates for starting and running friction in all roller
bearings. In other words, the bearing has the superior high speed performance of the flanged bushing.
3. The minimum maintenance requirements
Only a small amount of lubricant, you can make self-aligning ball bearings efficient operation. Its low friction and excellent design extend the relubrication interval. Sealed bearings need no lubrication.
4. Low noise and vibration level
A large number of comparative tests indicate that: Self-aligning ball
bearings precise, smooth raceway, with the lowest vibration and noise
levels.
Self-aligning ball bearings features and uses
Self-aligning
ball bearings have cylindrical holes and tapered bore two structures,
adhere to the material of a steel plate, synthetic resin. It is characterized by spherical outer raceway, with self-aligning
nature, you can make up for the different heart and shaft deflection
caused by the error, but its relative rotation of the outer ring must
not exceed 3 degrees.
Self-aligning ball bearing structure:
With
dust cover and sealed with deep groove ball bearing assembly has been
filled with the right amount of grease, the device should not be heated
before the need to clean, no lubrication during use, to adapt to the
operating temperature of -30 ℃ to + 120 ℃ between.
Self-aligning
ball bearings main purposes: For precision instruments, low noise
motors, automobiles, motorcycles and general machinery, machinery
industry, the most widely used type of bearings. Bearing model query software
Self-aligning ball bearings are double row bearings with a spherical outer ring raceway. Inner ring, ball, insist on the frame can rotate around the center of the bearing with self-aligning. Its centering ability can compensate for misalignment, shaft deformation and bearing deformation. Self-aligning ball bearings for the shaft and the upper center of the
shell difficult to bend the shaft easy to use bearings and other
purposes.
Self-aligning ball bearings
Self-aligning
ball bearings are processed into a spherical outer ring raceway, the
inner ring has two deep groove raceway double row ball bearings, with
self-aligning performance. It
is mainly used to accept radial load, radial load to accept at the same
time, also can withstand a small amount of axial load, but generally
can not accept the pure axial load, the lower limit speed of deep groove
ball bearings. This
type of bearing is mostly used in double bearing shafts that are prone
to bending under load and in parts with double bearing holes that can
not guarantee exact coaxiality. However, the relative inclination
between the centerline of the inner ring and the centerline of the outer
ring must not exceed 3 degree.
Self-aligning ball bearings basic types
The inner bore of the 121322 and 23 series self-aligning ball bearings can be cylindrical or conical. Bearing
bore taper 112 Code suffix K Self-aligning ball bearings can be mounted
directly to the conical shaft can also be installed through a tight
sleeve to the cylindrical shaft, FAG in addition to providing seal-free
self-aligning ball bearings, but also A basic type of self-aligning ball bearing with seal cap on both ends (code suffix 2RS
Self-aligning ball bearing bearing clearance
The
basic type of cylindrical hole Self-aligning ball bearings
manufacturing clearance group for the general group, the radial
clearance larger than the average group of bearings (suffix C3 suffix
for reference. The basic type of tapered bore self-aligning ball
bearings radial clearance C3 group is larger than normal group.
Sealed self-aligning ball bearings
Sealed
self-aligning ball bearings (code suffix .2RS with sealing cap on both
ends (contact seal.) To ensure the life expectancy, the factory has been
added to the grease. Sealed bearings minimum operating temperature
limit of -30 ℃.
