Double row angular contact ball bearings can withstand the same time characterized by joint load radial and axial load, limiting the axial displacement of both axes. Compared with the two-way thrust ball bearings, these bearings speed limit is higher, the contact angle of 32 degrees, rigid, can withstand the high precision bearings overturning moment, widely used in cars in the front wheel hub (some models also use the same size double row tapered roller bearings).
Structural deformation double row angular contact ball bearings, there are four:
Type A: 90mm outside diameter less than or equal to the standard design of the bearing. No ball gap, and therefore can withstand equal bi-axial load. Using lightweight glass fiber reinforced nylon 66 cage, bearing temperature rise is small.
Type A: 90mm outside diameter greater than the standard design of the bearing. Side of the ball gap, with z steel stamping cage or solid brass cage.
Type E: is to strengthen the structure, the side with filling slots that can hold more of the ball, so a higher carrying capacity.
Both sides with a dust cover type and sides Full complement cylindrical roller bearing with a ring-type, A-type and E-type design design double row angular contact ball bearings with dust cover can be both sides of the (non-contact) or seals (contact). Sealed bearings are filled with a rust-proof lithium grease, generally between -30 degrees to 110 degrees operating temperature. Without re-lubrication during use, before installation is no longer heated.
