Structural variations of double row angular contact ball bearings

Structural variants of double-row angular contact ball bearings
(1) Type A is a standard design for bearings with an outer diameter less than or equal to 90 mm. There is no ball filling notch, so it can withstand equal bidirectional axial loads. A lightweight glass fiber reinforced nylon 66 cage is used, and the bearing temperature rise is very small.
(2) Type A is a standard design for bearings with an outer diameter greater than 90 mm. There is a ball filling notch on one side, and it is equipped with a steel plate stamping cage or a brass solid cage.
(3) Type E is a reinforced structure with a ball filling notch on one side, which can accommodate more steel balls, so the load-bearing capacity is higher.
(4) Type A with dust covers on both sides and type E with seals on both sides Double-row angular contact ball bearings with dust covers (non-contact type) or seals (contact type) on both sides are available. The interior of the sealed bearing is filled with rust-proof lithium-based grease, and the operating temperature is generally between -30 and +110°C. No relubrication is required during use, and it should not be heated or cleaned before installation.
