Spot supply of imported bearings KOYO
   Structural deformation double row angular contact ball bearings, there are four:
   A Type: 90mm outside diameter less than or equal to the standard design of the bearing. No ball gap, it can withstand the equivalent of two-way axial load. Using lightweight glass fiber reinforced nylon 66 cage, the bearing temperature rise is very small.
   Type A: 90mm diameter greater than the standard design of the bearing. Side of the ball gap, with z steel stamping cage or brass cage entity.
   E-type: is reinforced structure, the side with filling slots, you can install more of the ball, so the higher carrying capacity.
   Both sides with a dust cover and sides with a ring type, A-type design and E-type design of double row angular contact ball bearings can be on both sides with a dust cover (non-contact) or seals (contact). Sealed bearings are filled with anti-rust lithium grease, generally between -30 degrees to 110 degrees operating temperature. Without re-lubrication during use, no heating before installation.
   When the double row angular contact ball bearing installation should be noted that although two-way bearings can withstand axial load, but if one side of the ball gap, it should be careful not to let the main axial load through the notched side gutter.
