The MA type self-aligning roller bearing adopts an externally guided brass alloy (steel plate alloy stamping) solid retainer, with an outer diameter surface of a spherical arc. There are two externally guided double half solid retainers in relative positions, and multiple oil grooves distributed along the circumference on the outer spherical surface perpendicular to the contact surface of the two double half solid retainers, enhancing the lubrication effect. This series of bearings has a large load-bearing capacity and can also be well used for impact loads. Bearings have the advantages of strong load-bearing capacity, good impact resistance, high reliability, good lubrication performance, and the ability to overcome shaft deflection deformation.

Application field: Mainly used in large-sized vibrating screens, as well as in situations where the speed changes rapidly or starts quickly, such as vibration, road rollers, and pile drivers.
