slewing ring bearings aligning bearings

aligning bearings, raceway is spherical shape, can adapt to the two bearing raceway deviation angle between the axis lines and angular high precision bearings‍ motion;

2) non self-aligning bearing (rigid bearing) - bearing raceway between the axis line impedance angle offset.

(4) according to the number of rolling body, divided into:

1) single row bearings -- with a rolling body bearing;

2) double row bearings -- with two rows of rolling bodies bearing;

3) multi row bearing - with more than two rows of rolling bodies bearing, such as the three column, four row bearings.

(5) according to their components are respectively, divided into:

1) respectively, Taper roller bearings‍ has respectively bearing bearing components;

2) can not be separately - bearing in the final after supporting bearings, rings are not bearing any free respectively.

(6) according to their structural shapes (such as with or without filling slots, with or without inner, outer ring and ring shape, structure, retaining edge very

To non retaining frame) can also be divided into structural types.

2 according to the rolling bearing size classification according to the outer diameter of bearing size, divided into:

(1) the miniature bearing, nominal diameter for bearing size below 26mm;

(2) small bearings -- nominal diameter size scale for 28-55mm bearing;

(3) small and medium-sized bearings, slewing bearing‍ nominal diameter size scale for 60-115mm bearing;

(4) in large bearing - Nominal outside diameter size scale for 120-190mm bearing

(5) the large bearing - nominal diameter size scale for 200-430mm bearing;

(6) extra large type bearing, nominal diameter size for the bearing more than 440mm.‍
