basic conception

Self-aligning ball bearing is two race between inner ring and groove for spherical outer ring, equipped with balls of ball bearings.

On the surface of the outer ring raceway curvature center and bearing center consistent, so with automatic self-aligning ball bearing the same tone heart function.In there was a deflection axis, a hood, can automatically adjust, not to increase the bearing burden.Spherical Roller Bearings can withstand radial load and two direction axial load.Large radial load capacity, suitable for heavy load and impact load.Inner circle diameter is tapered bore the bearing, it can be installed directly.Or the use of set cover, remove the cylinder installed on the cylinder axis.Keep rack stamping steel cage, polyamide forming keep frame and copper alloy car cage.

Summary of bearing

Self-aligning ball bearing with two structures of bore cylindrical or tapered and retainers made of steel sheet or synthetic resins.The bearings are characteristic of their way into spherical shape, have so can compensate concentricity and deflection self-aligning ball bearing

Into the error, but it shall not exceed 3 degrees between inner ring and outer.

The basic function

It is mainly used to bear radial load, the bear radial load at the same time, also can take a small amount of axial load, but usually can't bear to pure axial load, its limit rotational speed is low Deep Groove Ball Bearings.These bearings used in more easily bent double under the action of a load on the supporting shaft, and the double socket hole cannot ensure strict alignment components, but the relative slope of the center line of the center line of the inner ring and outer ring shall not exceed 3 degrees.

Self-aligning ball bearing applies to carry heavy load and impact load, precision instruments, low noise motors, automobiles, motorcycles, metallurgy, mill, mining, petroleum, paper making, cement, sugar and other industries and general machinery.

The basic classification

Self-aligning ball bearing has two columns of Steel ball , there are two inner ring raceway, the outer ring raceway is spherical shape, with automatic self-aligning performance.Can automatically compensate the deflection of shaft alignment errors caused by deformation and shell, is suitable for bearing seat hole can guarantee strict alignment section.This kind of bearings mainly take radial load, the bear radial load at the same time, can also carry a small amount of axial load, usually is not used for pure under axial load, such as subject to pure load, only a list of steel ball bearing.

Specific classification and model reference:

1, cylindrical hole self-aligning ball bearing (10000);

2, conical bore self-aligning ball bearing (10000 K);

3, with tight sleeves self-aligning ball bearing (10000 K + H10000 type)

Note: Self-Aligning Ball Bearings with cylindrical holes, tapered hole (10000 K) two kinds, mainly bear radial load, and can withstand axial load smaller shaft (shell) axial displacement limit within the clearance limit, with automatic self-aligning properties, allow the inner and outer relative tilt is not greater than -. Under the condition of normal work, suitable for bearing seat holes can't strictly ensure the alignment of parts.

3, with tight sleeves self-aligning ball bearing (10000 K + H10000 type)

Note: same as above The bearing is mainly used for shoulder on the optical axis of convenient installation and use, set set of adjustable radial clearance.

Basic common sense

Self-aligning ball bearing product features

Mainly bear radial load, and at the same time can carry small axial load.Shaft (shell) axial displacement limit within the clearance limit, with automatic self-aligning properties, allowed inside and outside under the condition of relatively little inclined to work properly, is suitable for bearing seat holes can't strictly ensure the alignment of parts.

Self-aligning ball bearing structure

The technical requirements

The classification of the rolling bearing the:

1. According to the rolling bearing structure type classification

(1) the bearing can bear the load according to its direction or nominal contact Angle different, divided into:

1) centripetal bearing -- - is mainly used to bear radial load of rolling bearings, the nominal contact Angle from 0 to 45.According to the nominal contact Angle is different, is divided into: radial bearing -- -- -- -- nominal centripetal bearing contact Angle 0: radial angular contact bearings -- -- -- -- nominal contact Angle is greater than 0 to 45 centripetal bearing.

2) thrust bearing -- -- - is mainly used for rolling bearings under axial load, its nominal contact Angle is greater than 45 to 90.According to the different nominal contact Angle is divided into: the axial bearing -- -- -- -- nominal contact Angle for the thrust bearing of 90: thrust angular contact bearings -- -- -- -- nominal contact Angle is greater than the thrust bearing of 45 but less than 90.

(2) according to the type of rolling element bearing,

Ball bearing can be divided into: 1) -- - for roller ball:

2) Roller bearing -- -- -- -- for roller roller. Roller Bearing press roller type, is divided into: roller bearing -- -- rolling body is Cylindrical roller bearing, cylindrical roller of the ratio of length to diameter less than or equal to 3; Needle Roller Bearing , rolling body is needle roller bearings, needle roller of the ratio of length to diameter is more than 3, but less than or equal to 5 mm in diameter; Tapered Roller Bearing -- -- rolling body is tapered roller bearing;Spherical roller bearings rolling body is Spherical roller bearing .

(3) according to its work when whether bearing, is divided into:

1) Self-Aligning Bearing -- -- raceway is spherical shape, can adapt to the Angle between the two raceway axis deviation and angular motion bearing;

(2) the self-aligning bearing rigid bearing) - - can the impedance between the raceway bearing axis Angle deviation.

(4) according to the column number of the rolling element bearing, is divided into:

1) single bearing -- -- - with a list of rolling element bearing;

2) double row bearings -- - with two columns of rolling element bearing;

3) more columns bearing -- -- -- - with more than two columns of rolling element bearings, such as three, four row bearings.

(5) bearing according to their components can be separated, is divided into:

1) separable bearing -- -- -- -- have separable components bearing;

Integral bearing -- - bearing 2) after the final matching, bearing ring are not free any separation.

(6) bearing according to their structural shapes (such as presence of loading slot, with or without inner and outer ring, and the shape of a ring, the structure of the guard, even the presence of cage, etc.) can also be divided into a variety of structural types.2. According to the rolling bearing size classification Bearing on its outer diameter size, can be divided into:
