    Self- Aligning Roller Bearings

    Aligning roller bearings can support large load and

    vibration load and make up for coaxially error informed by

    axis installation with axis bending deflection. It is

    divided into symmetric form and unsymmetrical form.

    Compared with unsymmetrical form, symmetric form

    2000C( CC& CA) ( 5300) is possessing small frictional

    resistance, large load capacity, long life and etc and it

    should be prior option.

    Unsymmetrical form 2000( 3000) is eliminating product and

    unfavorable choose for new machine.

    IDB aligning roller bearings are mainly used in the industry

    of mine, steel and sea transportation.
