Deep groove ball bearing high temperature deep groove ball bearing structure is simple, using the bento, is consumption quantity is big, the most widely application scope of bearing, mainly bear radial load, also can carry a small amount of bidirectional axial load at the same time, at work inside and outside the circle axis allows deflection 8 & prime; ~ 16 '; 。 Small friction, high limiting speed, simple structure, low price, the most common applications. But bear impact load ability is poor. When applied to high speed, high speed, may replace the thrust ball bearings to withstand pure axial load. (1) basic type deep groove ball bearings, 60000, to install, seal, with no special pleading. (2) deep groove ball bearing with dust cover: take one dust cover or double dust cover, dust cover adopts 8 or 10 steel, and the radial clearance between inner ring guard, limit rotational speed is the same as the basic deep groove ball bearings. Such as: 6203 z. (3) with seals deep groove ball bearings, with seals on one side and two sides with seals, ordinary steel skeleton type nitrile butadiene rubber sealing ring, sealing lip contact with inner ring guard radial, as the contact seal, the sealing effect is good, but the friction resistance is bigger, the limit rotational speed is low, do not contact with inner ring guard, assumes that the sealing lip is non-contact seal, its limit rotational speed is the same as basic deep groove ball bearings, such as 62032 rz, 62032 rs. (4) with locking slot of deep groove ball bearings, on the outer ring arranged stop ring rectangular groove, such as: 6203 n, beneficial to simplify the axial location of bearing in the bearing hole. Tapered roller bearings taper roller bearing is mainly applied to accept mainly consisting of radial load and axial combined load, also can accept larger radial load and axial load of one-way, limit rotational speed is low. And big cone Angle of the taper roller bearing can accept is given priority to with axial load of diameter, the axial load, the bearing inner and outer circle do not, bearing clearance can be adjusted in the device, usually used in pairs, symmetric device. Apply to speed is not too high, the axial rigidity good place. Tapered roller bearings, the size of the axial clearance of the bearing can impact on the good work, when the axial clearance is too small type, rise; The axial clearance is too large, the bearing is easy to damage. (1) single row tapered roller bearing type 30000, these bearings can limit axial displacement of shaft or housing in one direction, accept a direction of axial load. Under the action of radial load, can produce additional axial force. Common end with the same relative device, if applicable, alone its plus axial force must be greater than the additional axial force. (2) double row circular cone roller bearings 350000 type: this kind of bearing has a pair of raceway outer ring and two inner ring, between the inner ring with one circle, change the thickness of the baffle can adjust bearing clearance and the bearing under radial load of acceptable bidirectional axial load at the same time, can within the scope of the bearing axial clearance limit shaft and the shell two-way axial displacement. (3) four row circular cone roller bearings 380000 type: this USES two double raceway bearing inner ring, a double raceway outer ring and two single raceway outer ring, inner ring and outer ring are beneficial to adjust the clearance between baffle, its performance and double row bearing is the same. Can accept the big radial direction load, but limit rotational speed is low. Tapered roller bearing is mainly applied to accept mainly consisting of radial load and axial combined load, also can accept larger radial load and axial load of one-way, limit rotational speed is low. And big cone Angle of the taper roller bearing can accept is given priority to with axial load of diameter, the axial load, the bearing inner and outer circle do not, bearing clearance can be adjusted in the device, usually used in pairs, symmetric device. Apply to speed is not too high, the axial rigidity good place. Tapered roller bearings, the size of the axial clearance of the bearing can impact on the good work, when the axial clearance is too small type, rise; The axial clearance is too large, the bearing is easy to damage. (1) single row tapered roller bearing type 30000, these bearings can limit axial displacement of shaft or housing in one direction, accept a direction of axial load. Under the action of radial load, can produce additional axial force. Common end with the same relative device, if applicable, alone its plus axial force must be greater than the additional axial force. (2) double row circular cone roller bearings 350000 type: this kind of bearing has a pair of raceway outer ring and two inner ring, between the inner ring with one circle, change the thickness of the baffle can adjust bearing clearance and the bearing under radial load of acceptable bidirectional axial load at the same time, can within the scope of the bearing axial clearance limit shaft and the shell two-way axial displacement. (3) four row circular cone roller bearings 380000 type: this USES two double raceway bearing inner ring, a double raceway outer ring and two single raceway outer ring, inner ring and outer ring are beneficial to adjust the clearance between baffle, its performance and double row bearing is the same. Can accept the big radial direction load, but limit rotational speed is low. Thrust ball bearing ring and rolling body mostly respectively, contact Angle of 90 degrees. A one-way or two-way. One-way thrust ball bearings can only carry axial load one-way, limit shaft and the shell axial moving in one direction, two ring inner hole is not as (so), inner diameter is smaller ring ( Axial circle) Cooperate with shaft, larger inner hole of the loose circle ( Seat) , and base fixed in together. Limit rotational speed is low, suitable for big axial force and rotational speed is low. Bidirectional thrust ball bearing can be subject to bi-directional load and can limit shaft and shell of two directions, the middle ring ring, cooperate with shaft, the other two ring for loose circle. High speed, because of the large centrifugal force, the ball and stick to fever severely due to friction, low service life. Often used in large axial load, speed is not high.
