What is the importance of the spherical roller bearings?

Spherical roller bearings have two rows of rollers, which mainly bear radial loads, as well as axial loads in either direction. It has high radial load capacity, especially suitable for working under heavy load or vibration load, but cannot bear pure axial load. The outer ring raceway of this type of bearing is spherical, so its self-aligning performance is good, and it can compensate for the coaxially error.

What causes the black flakes of the spherical roller bearing raceway?

Ideally, when the groove position deviation is 0 after turning, the groove grinding allowance is uniform, and the raceway size during turning has taken into account the influence of the face grinding error on the raceway grinding. Since the end face grinding allowance of the spherical roller bearing is limited, and the two end faces are ground at the same time by a double end face grinder, even if the grinding is offset, it will not cause black skin on the edge of the raceway. In fact, the appearance of unilateral black skin on the raceway is due to the fact that when the channel is machined, a large amount is left, while a small amount is left, and black skin is produced on the side with a small amount of reserve, and even the product is scrapped.

What is the function of spherical roller bearings?

Spherical roller bearing is a precise mechanical element that converts the sliding friction between the running shaft and the shaft seat into friction, thereby reducing friction loss. The bearing is generally composed of four parts: inner ring, outer ring, body and cage. The function of the inner ring is to cooperate with the shaft and rotate with the shaft; the function of the outer ring is to cooperate with the bearing seat and play a supporting role; The cage evenly distributes the body between the inner ring and the outer ring. The shape, size and quantity of the spherical roller bearing directly affect the performance and life of the bearing; the cage can make the body evenly distributed, and the guide body rotates for lubrication.

Why is the high temperature adaptability of spherical roller bearings very important?

Today, the high temperature adaptability of the lowering spherical roller bearing is introduced in detail. The shaft parts of the machine tool, especially the main shaft, are generally assembled with bearings or sliding bearings, and rotate at high speeds, sometimes generating high heat.

The shaft parts of the machine tool, especially the main shaft, are generally assembled with bearings or sliding bearings, and rotate at high speeds, sometimes generating high heat. If this phenomenon is not eliminated in time, it will lead to overheating of the bearing, and the temperature of the corresponding parts of the machine tool will increase, resulting in thermal deformation. Burn out the spherical roller bearing.
