* ring and ball contact Angle between the two, the standard contact Angle of 15 & deg;
,30度;
And 40 & deg;
* contact Angle, the greater the axial load capacity is also * contact Angle is smaller, the more the greater the high-speed rotation (
旋转)
* single bearing (
轴承)
Can bear radial load and combination of unilateral axial load * DB, DF combinations and double row bearings can bear radial load and bidirectional axial load * DT combination used one-way axial load is bigger, a single bearing (
轴承)
The occasion of the rated load of insufficient * high-speed with ACH type bearing (
轴承)
Ball diameter is small, many, mostly used for machine tool spindle,
主轴)
* angular contact ball bearings are suitable for high speed and high precision of rotating * structure on the back of the combination of the two single row angular contact ball bearings (
轴承)
Sharing of inner ring and outer ring, can bear radial load and the bidirectional axial load * no loading groove bearings are sealed type cage is mainly used: * steel (
钢板)
Punching cage (
Bowl single;
S form, crown double column)
* copper (
Chemical formula Cu)
Alloy cage, synthetic or phenolic resin system (
Explanation: from the merger of several parts into a whole)
Cage resin forming main use: * single: machine tool spindle, high frequency,

The front wheel, differential pinion (

Axis * double row: oil pump (

* four-point contact ball bearing can bear radial load and bidirectional axial load * a single bearing can be combined to replace the front or the back combination of angular contact ball bearing * applies to pure axial load or under axial load ingredients * the larger synthetic load bearing (
轴承)
Carry axial load in any direction can be formed when one of the contact Angle (
α
)
, so the ring in contact with the ball always * any online double-dealing contacts is mainly used in the cage: copper alloy cutting keep main use: aircraft jet engines (
