Angular contact bearings and spherical bearings difference

1: Angular contact ball bearings:
1. Single bearing can tolerate this type of axial load in one direction, also need to configure other bearings to offset the additional axial force, made on the installation of the additional axial force which offset each other, and can afford two Power up the axial load, and has two directions of a strong axial limit capacity, generally installed in pairs using two sets of bearings in its outer end is relatively wide (back to back) or the relatively narrow end (face) two to install forms, including back to back installation of the best rigid bearing system. For ease of installation in pairs or groups, some bearing plants supply pairs, a group of three and four sets of bearing such a group,
This supply of bearing the same batch processing consistency, use a more uniform load to bear the additional axial forces cancel each other out more thoroughly.
2. This type of bearings are separable and can not be non-release of two, separate bearings for restricted installation conditions, required from the outer or inner set of bearings were installed in order to remove the case, because separation-type angle contact ball bearing is widely used in magnetic motor, so also known as magnetic motor bearing. This type of bearing in locking in the inner ring on the variety, can be adapted to a higher speed.
3. Most of pairs of angular contact ball bearings used for small-span rigid double-precision support shaft or spindle, used to carefully adjust clearance, changes in bearing, the outer axial distance can be adjusted bearing internal clearance, At the same time can be several sets of bearings in parallel pre-installed and give some amount of interference, the system can improve the bearing stiffness.
2: Insert Bearing:
Insert bearings and deep groove ball bearings of basic performance should be similar, but because of this relatively rough bearing most of the machinery used in the installation orientation is not precise enough, the hole axis and the seat difference of neutral axis, or long axis and large deflection of the case, and bearing their accuracy is also not high enough, some structures are more rough, so the actual performance were relatively the same performance specifications deep groove ball bearings Yaoda quite a discount. For example, the top wire with the outer spherical ball bearings used in large stiffness difference through shaft deflections, which both sides with a ring bearing, can close to prevent dirt intrusion, the factory had the right amount of lubricant filling,
No cleaning before installation, without of additional lubricant, bearing inner ring on the top end of wire protruding screws in the shaft when tightened. Permissible dynamic axial load shall not exceed the rated load of 20%.
With eccentric sleeve insert ball bearing with spherical outside the wire with the top bearing the same performance, but not in the inner ring on the top wire, but put on the eccentric. Insert bearings tapered bore of the hole to hole with 1:12 taper of the cone, can be directly installed in the cone axis, or with adapter bushing installed in the shaft axis on the shoulder, and can fine-tune the bearing clearance.
