    Hydrodynamic Bearing

    Hydrodynamic Bearings

    ZYS hydrodynamic bearings belong to oil lubricated sliding bearings, depending on the hydrodynamic in frictions to support external loads.

    One Way Bearing

    One-way Bearings

    ZYS One Way Bearings are the combination of deep groove ball bearing (6200 series) and freewheel clutch(one way clutch). Their boundary dimensions are the same as 6200 series deep groove ball bearings. The lubrication grease has been filled inside.

    Spherical Roller Bearings

    ZYS spherical roller bearings have double-row rollers, mainly supporting radial loads and axial loads at the same time, except the pure axial load. They are applicable to paper manufacturing machinery, speed reducer, rolling mills gearbox, crusher, printing machinery, wood-working machine, etc.

    Deep groove ball bearing

    Standard Ball Bearings

    Among ZYS standard ball bearings, deep groove ball bearings are the commonest bearings.Self-aligning ball bearings have good aligning property due to the spherical outer raceway.?nsert ball bearings are mounted and dismounted easily, also have the aligning property. Thrust ball bearings have separable shaft washer, housing washer, and ball/cage assembly.

    Taper Roller Bearing

    Taper Roller Bearings

    ZYS taper roller bearings mainly support radial load and axial load as well. The load carrying capacity depends on the angle of outer raceway, the bigger the angle is, the larger the load carrying capacity will be.
