  • Angular Contact (Spindle) bearings | Principle

    Angular contact ball bearings (also known as spindle bearings) are bearings where the inner and/or outer ring shoulders are relieved. Relieving the shoulder allows the ball complement to be changed to give greater load capacity (larger balls or a greater number of balls) and a stronger retainer, allowing higher speed and better endurance.
