Aligning ball bearing is a spherical outer ring raceway double row bearings. The inner ring, balls, cage can rotate freely around the bearing center, with self-aligning. Their self-aligning capability can misalignment, axial deformation and bearing deformation compensation. Self-aligning ball bearings for shaft and the housing difficulties for the central shaft deflection prone transmission bearings and other purposes.
Aligning ball bearings
Aligning ball bearing outer ring raceway is processed into a spherical shape, there are two inner raceway of double row deep groove ball bearings, aligning performance. It is mainly used to bear radial load, radial load, but also can withstand a small amount of axial load, but generally can not bear the pure axial load, the speed limit lower than the deep groove ball bearings. This kind of bearing more prone to bending under load double bearing shaft and double bearing hole can not guarantee strict concentricity of the parts inside, but the relative inclination of the inner ring and outer ring centerline centerline shall not exceed 3 degrees.
Aligning ball bearings basic types
12,13,22 and 23 series bore self-aligning ball bearings can be cylindrical or conical. Bearing bore taper 1:12 (code suffix K) self-aligning ball bearings can be installed directly to the cone axis, you can also install an adapter sleeve to the cylindrical shaft, FAG addition to providing free sealed aligning outer ball bearings, but also provide with closures at both ends of the basic types of self-aligning ball bearing (code suffix 2RS).
Aligning ball bearings clearance
The basic types of cylindrical bore self-aligning ball bearing manufacturing clearance group for the general group, radial clearance larger than normal group bearing (code suffix C3) that is available on request. The basic types of conical bore self-aligning ball bearing radial clearance is larger than a typical group C3 group.
Seal-aligning ball bearings
Seal-aligning ball bearing (code suffix .2RS) at both ends with closures (contact seal). To ensure the life that they had been joined at the factory grease. Sealed bearings minimum working temperature limit of -30 ℃.
Aligning ball bearing pairs
Aligning ball bearings allow the shaft center bearing deflection around 4 °, sealed self-aligning ball bearings can compensate for a maximum 1.5 °.
1. accommodate misalignment conditions
Self-aligning ball bearings than any other bearing misalignment can better adapt to the situation. That makes the situation in the rock, the bearing still running smoothly.
2. Excellent high-speed performance
F & F Self-aligning ball bearings in all the roller bearing, has the lowest friction up and running. In other words, the bearing with excellent high-speed performance.
3. Minimum maintenance requirements
Only a small amount of lubricant, you can make self-aligning ball bearings running efficiently. Its low friction and excellent design, extending the re-lubrication intervals. Sealed bearings do not need lubrication.
4. Low noise and vibration levels
A large number of comparative tests show: Self-aligning ball bearings precise, smooth raceway, it has the lowest vibration and noise levels.
Aligning ball bearing characteristics and uses
Aligning ball bearings cylindrical and tapered bore two structures, cage made of steel sheet, synthetic resin. It features an outer ring raceway spherical shape, with auto-Mind, can compensate for misalignment and shaft deflection caused by the error, but the inner and outer rings relative inclination of not more than 3 degrees.
Aligning ball bearing structure in the form of:
With a dust cover and has been filled with a ring of deep groove ball bearing assembly when the right amount of grease should not be heated before installation do not have to wash, use the process without re-lubrication, to adapt to the operating temperature of -30 ℃ to + 120 ℃ of room.
Aligning ball bearings main purposes: for precision instruments, low noise motors, automobiles, motorcycles and general machinery, the machinery industry, the most widely used class of bearings
