Advantages of new bearings compared to traditional self-aligning rollers:


 Spherical Double Row Roller Bearings

Spherical Roller Bearing


1.The barrel of the mill must have a certain inclination, and the outer ring with a radian is designed to adjust the inclination and misalignment of the mill.2. Thermal expansion and contraction occur during mill production, and the inner ring is designed without ribs, which solves the problem of thermal expansion and contraction encountered in the production process of the mill due to high material temperature and regional temperature differences.3.The mill is fixed: the discharge end is designed with double gears, which satisfies the positioning function of the mill barrel and makes the operation more stable. The feed end adopts a design without ribs, which meets the telescopic function of the mill cylinder, and the running resistance is smaller.4. Mill bearing lubrication: The outer ring of the bearing is designed with 3 positioning holes, and each hole has an oiling thread. It is more convenient for users to lubricate the problem. 1. The centering of the inclination of the mill is completed by the self-aligning of the arc-shaped raceway of the self-aligning roller bearing.2.It does not have telescopic function, and is suitable for constant temperature environment and non-temperature materials.3. The inner ring of the self-aligning roller bearing used at both the inlet and outlet ends of the mill has double gear sides, both of which have the positioning function. There is no axial sliding function.4. The self-aligning roller has three oil holes

Load Capacity

The mill is subject to high radial load: we use two rows of linear raceway design, with more contact surfaces to carry high load and reduce impact load, so as to achieve the bearing weight and impact load required by the mill. The spherical roller bearing raceway is an arc-shaped contact surface with a small contact area. Large mills have limited weight load capacity.

Life Span

The service life can generally reach 10-12 years. The general service life of spherical roller bearings is 3-5 years

Energy saving

The double raceway design has smaller running resistance and significantly lower starting resistance, which can save electric energy; it is convenient for maintenance and saves a lot of water resources. The energy-saving effect of the curved raceway contact surface is not obvious
