Deformation of the structure of double row angular contact bearings
1) A type of bearing outside diameter less than or equal to 90mm standard design. Non-loaded ball gap, so they can withstand the equivalent of two-way axial load. Using lightweight glass fiber reinforced nylon 66 cage, bearing temperature rise is small.
(2) A type of bearing outside diameter greater than 90mm standard design. Side of the ball gap, with a pressed steel cage or solid brass cage.
(3) E-type structure is enhanced, the side with filling slots that can hold more of the ball, so the higher carrying capacity.
(4) sides with a dust cover type and sides with a ring-type A-type and E-type design designed double row angular contact ball bearings can be on both sides with a dust cover (non-contact) or seal (contact ). Sealed bearings are filled with rust inside lithium grease, operating temperature is generally -30 ~ +110 ℃. No further lubrication during use, should not be heated before installation should not be cleaned.
