high speed Spherical Roller Bearings are composed of a double inner raceway, a spherical raceway outer race, double row spherical rollers, and a cage. The center of the outer raceway is consistent with the center of the bearing, and it has the function of self-aligning, which can compensate for the installation error between the shaft and the bearing seat or the inclination of the inner and outer rings caused by the deflection of the shaft. It can withstand large radial loads and certain bidirectional axial loads. It is especially suitable for occasions under heavy load or vibration.

Conical bore

In addition to the cylindrical inner hole, the inner ring also has a conical inner hole. 204 and 241 series bearing tapered inner hole taper is 1:30, and the rear code is K30; other series bearings have a taper of 1:12, and the rear code is K.

Alignment angle allowed

Under normal load and constant eccentric working conditions of the inner ring, if the bearing installation space and seal type allow, the allowable alignment angle is as follows.

Lubricating oil sump oil hole

Spherical roller bearings are provided with inner or outer rings with lubricating oil grooves and oil holes according to the needs of the lubrication method. The characteristic code with lubricating oil groove and oil hole is after the "/" in the code of the spherical roller bearing, and the meaning of the post code is as follows:

Sealed Bearings For heavy loads, harsh working conditions or bearing arrangements with special sealing requirements, built-in contact sealed spherical roller bearings can be provided. The outer dimensions of the bearing are exactly the same as the non-sealed bearing, and can replace the non-sealed bearing in many occasions. The allowable centering angle is 0.5°, and the working temperature is -20°C-110°C. An appropriate amount of lithium-based anti-rust grease has been filled in the bearing, and grease is also filled according to user requirements.

Anti-vibration bearings

This bearing is specially designed for vibrating screen or other vibrating machinery. Its structural features are: an asymmetric spherical roller spherical roller bearing with two rows of independent car-made solid cages guided by the outer ring. Its radial clearance is between the upper half area of C3 and the lower area of C4.

MA Spherical Roller Bearing

High precision, anti-vibration, low noise，Suitable for more rugged environments

The working environment of the bearing is very harsh, not only the environment has high humidity, dust particles, high speed, high temperature, but also strong vibration and shock, resulting in a very heavy workload. The bearing has good impact resistance, strong load capacity, good lubrication performance, high reliability, and can overcome the deflection and deformation of the shaft.

CC cage feture

The rollers are symmetrical, the inner ring has no middle ribs and no end ribs. The cage is split. The material is a stamped steel frame cage. A movable intermediate ring is designed between the roller and the roller. Its function It can effectively reduce the internal friction of the bearing, can effectively assist the rolling elements in the non-stressed area to enter the load area correctly, and also increase the limit speed of the bearing.

	High quality steel Xingcheng steel Precise grinding treatment of bearings to reach P5 level.		High temperature resistant and tough cage The cage is manufactured using FAG technology to make the bearing more resistant to high temperatures and enhance toughness.
	The outer ring of P5 grade, Precise grinding treatment 3 times to reach P5 grade		Precise treatment of oil holes to extend bearing life Precise grinding treatment 2 times,Smooth surface without burrs to extend bearing life.

Compared with the CA structure, the tensile strength of the CC type cage has been greatly improved. At the same time, because the CC structure design occupies less internal space of the bearing than the CA structure design, the number of rolling elements is increased and the shape of the rolling elements is changed. The size, which can improve the radial bearing capacity of the bearing to a certain extent, so it can withstand a larger axial bearing capacity than the CA structure design.

Application

It is mainly used in high-efficiency impact crushers in the secondary and tertiary fine crushing industries, as well as mining machinery, crushers, gear boxes, steel rolling conveyors, reducers, rolling mill tension rollers, etc.
