ZWZ produces standard angular contact ball bearing with three kinds of angles: 150 (name suffix is C), 25 ° (name suffix is AC), 40° (name suffix is B), The bearing with bigger contact angle recommended for application scenarios like high axial rigidity and high axial load carrying capacity; According to different working conditions, ZWZ also can design and produce angular contact ball bearing with special angles.
According to difierent requirements of installation control, ZWZ's precision angular contact ball bearing has different bearing series like 70, 72, 719 and etc. In high speed or minimum radial clearance conditions, it's better to choose 719 or 70 series bearing. For the heavy load and medium speed conditions, 72 series bearing is suitable. 719 series bearing fits to the conditions where stiffiiess requirements are extremely important, because it has many rolling elements and fits to large diameter main shaft, all of these fectors help to make main shall system have high rigidity. In view of the high speed trend of main shaft, ZWZ has specially researched and developed HA series high speed angular contact ball bearing to adapt high speed main shaft conditions.
