Single-row spherical roller bearings are self-retaining radial roller bearings. They also belong tp s;elf-aligning bearings. Benefit from the concave raceway on the outer ring, the SRB bearing are able to compensate the static and dynamic angular misalignment under certain limits. Inner ring is equipped with two fixed ribs and a formed raceway. The rollers are guided between the two inner ring ribs. Solid cages from ZWA single-row spherical roller bearings are mainly brass ones. ZWA offered two bore types for single row spherical roller bearing, one is cylindrical bore and the other is tapered.

Rolling elements in single-row spherical roller bearings contact with the raceway in line. With this feature, the bearings are able to bear very high radial capacity loads and relatively low axial capacity load. Because of the concave raceway on the outer rings, single-row spherical roller bearings are able to adjust the angular misalignment.

ZWA’s single-row spherical roller bearings have served the customers well. Its production range is from the inner ring 50mm to 200mm. With its reliable bearing quality and after-sale service, ZWA bearings have assisted the customers to realize the following goals:

Reduce the cost

There are many top 10 bearing manufacturers in china, but we are the best choice for you.

Rollers are the components bored with loads in bearing operation. They are also the weakest component whose quality will directly affect the bearing’s performance like rotating speed, vibration level and flexibility. It’s also the key element for service life of bearings. Based on different categories, rollers can be divided into spherical, tapered, cylindrical rollers. According to different precision level, they are divided into grade I, II and III.

ZWA’s precision spherical roller bearings are with least grade II and raw materials are with European standard. The production capacity of ZWA is 80,000 to 100,000 piece monthly.

Double row spherical roller bearing are the most widely used types in group of radial roller bearings. They have two rows of rollers, curved raceway in the outer ring and two raceways in the inner ring. The design of raceways make the bearings combine different characteristics in one bearing, for example, adjusting the angular loads. In general,  the symmetrical rollers are guided by press steel cages or machined brass cages in ZWA’s production range.

The contact surface of the rollers will determine the allocation of stress at the contact points between the raceways and rollers. Owing to this feature, the geometry of rollers matches with the raceway.

In general, ZWA Bearing offers the double spherical roller bearing with both steel cage and brass cage, for the steel cage, it mainly contains CC type which has the following features:

Two pressed window-type steel cage, the inner ring is without flanges and a guide ring is centered on the inner ring.

For the brass cage, it mainly contains CA, MB, and MA types.

For CA cage, it has the following features

One machined brass cage, the inner ring is with retaining flange on both sides and one guide ring centered on the inner ring. The flange will keep the rollers in position while rotating the bearing in process of mounting or maintenance. It doesn’t guide the rollers or bear any axial load.

For MB cage, it has the following features

Two brass cages, inner ring guided with two retaining ribs and one central rib.

For MA cage, one brass cage, outer ring guided with two retaining ribs and one central rib.

ZWA’s double-row spherical roller bearings favor the customers to realize the following aims

Reduce the cost

Increase productivity

Higher machine availability

Features of double-row spherical SRB bearing:

Bear high or very high radial loads

Bear relative high axial loads on one or both sides.

Reduce the friction

Compensate the misalignment

Cylindrical roller bearings ( also called CRB in short) are a kind of radial rolling bearings with cylindrical rollers. The rollers are lined in parallel shapes, in between the rollers are cages that are able to avoid the leaning of roller or friction between rollers. In consequence, the rotating torque is also avoided. The contact between the cylindrical rollers and the raceways is linear contact. In general, cylindrical roller bearings adopt pressed steel cages or machined brass cages. This design is employed by leading manufacturers like ZWA Bearings, one of the leading China cylindrical roller bearing manufacturers.

Types of cylindrical roller bearings

Cylindrical roller bearings can be classified in several types based on different index. Based on the row of rollers, cylindrical roller bearings can be divided into single row cylindrical roller bearing, double row cylindrical roller bearing and four row cylindrical roller bearing. Based on the ribs of the rings, cylindrical roller bearings can be divided into NU, NJ, NUP, N, NF, NNU, NN etc types. For this classification, the inner and outer ring are separable. ZWA Bearings manufactures types of cylindrical roller bearings to meet customers' demand in diferent industries like mining, steel making, etc.

Single Row Cylindrical Roller Bearing

Single row cylindrical roller bearings with cages are part of radial roller bearings. Compared with the ball bearings’ balls, the rollers have a bigger contact to the roller axle.

Double Row Cylindrical Roller Bearing

The rollers of double row cylindrical roller bearing are crossing arranged. While rotating, the wave ratio is one time higher than single-row cylindrical roller bearings.

Four Row Cylindrical Roller Bearing

Four-row cylindrical roller bearings are kind of separable bearings. The rings and roller components are easily separable.

Full Complement Cylindrical Roller Bearings

Full complement cylindrical roller bearing is a kind of cylindrical roller bearing designed without cages. In this design, the number of rollers are the biggest in all the bearings types.

Cylindrical Roller Thrust Bearing

Cylindrical roller thrust bearings consist of rollers, cage components, shaft ring and housing ring. Those components are separable for efficient and convenient operations.
