20*47*14 S~aligning ball bearing11204

S-aligning ball bearing 11204Dimension:20*47*14Once ordered, please inform me which type you need? .... thanks.

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

The s-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 s-aligning ability, which can compensate the error caused by the s-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 s-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 .

S-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 oiroove and three oil holes are hined on the outer ring of the bearing.

Structure type

The s-aligning ball bearing with dust cover and sealing ring has been filled with a proper amount of grease during aembly. 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 s-aligning ball bearings: It is suitable for precision instruments, low-noise motors, automobiles, motorcycles and general hinery, etc. It is the most widely used type of bearing in the hinery 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 baluided hined bra solid cage

2RS: with sealing caps at both ends

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

Use

S-aligning ball bearings are suitable for industries such as heavy and sholoads, precision instruments, low-noise motors, automobiles, motorcycles, metallurgy, rolling mills, , petroleum, papering, cement, sugar exction, and general hinery.
