Self-aligning ball bearing 2209/2209K

Dimension:45*85*23

Once ordered, please inform me which type you need? .... thanks.

The self-aligning ball bearing has two structures: cylindrical hole and conical hole. The material of the cage is steel plate, synthetic resin, etc. Its feature is that the outer ring raceway is spherical and has self-aligning ability, which can compensate for errors caused by different center degrees and shaft deflections, but the relative inclination of the inner and outer rings must not exceed 3 degrees.

The self-aligning ball bearing is a bearing equipped with spherical balls between the inner ring of two raceways and the outer ring with spherical raceways.

The self-aligning ball bearing has two structures: cylindrical hole and conical hole. The material of the cage is steel plate, synthetic resin, etc. Its characteristic is that the outer ring raceway is spherical and has self-aligning ability, which can compensate the error caused by the self-aligning ball bearings with different centers and shaft deflections.

Can withstand larger radial loads, but also withstand certain axial loads. The outer ring raceway of this type of bearing is spherical, so it has self-aligning performance. When the shaft is bent or tilted by force and the center line of the inner ring and the center line of the outer ring are not inclined more than 1 ° ~ 2.5 °, the bearing can still work .

Self-aligning ball bearings have cylindrical and conical bores. The taper of the conical inner hole is 1: 1 2 or 1:30. In order to enhance the lubrication performance of the bearing, an annular oil groove and three oil holes are machined on the outer ring of the bearing.

Structure type

The self-aligning ball bearing with dust cover and sealing ring has been filled with a proper amount of grease during assembly. It should not be heated or cleaned before installation. It does not need to be relubricated during use. It is suitable for operating temperatures-30 ℃ to + 120 ℃ between. The main purpose of self-aligning ball bearings: It is suitable for precision instruments, low-noise motors, automobiles, motorcycles and general machinery, etc. It is the most widely used type of bearing in the machinery industry;

Miniature series: 10x, 12x, 13x

General series: 12xx, 13xx, 22xx, 23xx

C3: Radial clearance is larger than ordinary clearance

K: 1/12 taper cone hole

K30: 1/30 taper cone hole

M: Steel ball guided machined brass solid cage

2RS: with sealing caps at both ends

TV: glass ball reinforced polyamide (nylon) solid cage guided by steel balls

Use

Self-aligning ball bearings are suitable for industries such as heavy and shock loads, precision instruments, low-noise motors, automobiles, motorcycles, metallurgy, rolling mills, mining, petroleum, papermaking, cement, sugar extraction, and general machinery.
