The inner ring unit includes one inner ring, one group of tapered rollers and a cage. In ZWA’s same type single row tapered roller bearings,both inner ring and outer ring can be exchangeable with other inner rings and outer rings. In general, the tapered angle of outer ring raceway is between 10°~19° and the contact of roller and raceways is linear one. Therefore, it can bear combined axial and radial loads, also single axial loads. The bigger the tapered angle, the bigger axial load capacity can be accommodated. As the extending line of raceways meet at the same point of the bearing axis, in operation, single row tapered roller bearing has lower friction torque. <br> <br>ZWA, as a China ball and roller bearing company, offers pure single row tapered roller bearings and matched single row tapered roller bearings (i.e. back to back or face-to-face mode). According to different contact angles, single roller tapered roller bearings can be classified into three types: small cone angle, medium cone angle, and big cone angle.

Compared with the ball bearings’ balls, the rollers have a bigger contact to the roller axle. As a consequence, it can transfer higher forces, has higher stiffness, and in the same capacity load working condition, the diameter of the roller can be smaller. The rollers own profiled ends. For the basic design of all cylindrical roller bearings, the cylindrical rollers are guided within two ribs by at least one ring. This ring matches with the cage and rollers and become a fit unit. The other ring is removable and easier to mount and dismount.In general, the fit of the rings are tight one. Based on different arrangement of the ribs on the inner ring and outer ring, the bearings can be divided into NU, N, NJ, NF and NUP types.

ZWA provide the service and technical advice on the bearing selection. Those selection is not only customized but also cheap on price. Please contact us for optimized your equipment performance by the most suitable bearings. <br> <br>Spherical Roller Bearings <br>Spherical roller bearings are designed to adapt to severe misalignment caused by mounting or deflection on the shaft &amp; housing. Not every type of bearing has the ability to face the challenge of misalignment. Meanwhile, due to its two row of rollers, spherical roller bearings are able to bear high radial loads and some axial loads. They adopt a spherical or crowned rollers as rolling elements and raceway of the outer ring is also in spherical shape. For shock loads, their feature of self-aligning helps to absorb but has limited capabilities to high speed. As one of the widely used bearings, spherical roller bearings do you a favor in obtaining lower maintenance cost, increasing the productivity and prolong the service life. <br> <br>Cylindrical Roller Bearings <br>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. <br> <br>Tapered Roller Bearings <br>Tapered roller bearings, also known as TRB bearing, are also a kind of bearing that can be separated, a tapered raceway featured the inner and outer rings. Tapered roller bearings can bear large axial forces and function like thrust bearings. They can also manage large radial loads. Tapered bearings are an improvement on journal bearings. Tapered roller bearings don’t need to add frequent lubrication to avoid overheating and failure. <br> <br>Toroidal Roller Bearing <br>Toroidal roller bearings are kind of new single-row radial bearing. It has crowned symmetrical rollers and circular ring raceways.The rollers of the toroidal bearings are self-guiding, that’s to say they adjust the position in which the loads are averagely distributed over the length of the rollers no matter the inner ring is axial displaced or not. The raceways of the inner rings and outer rings are concave and arranged symmetrically about the center of the bearings. <br> <br>Split Bearings <br>Split roller bearings are specially designed based on the original spherical roller bearings and cylindrical bearings. The aim of split bearings is to solve the problem of quick replacement of bearings at unattainable positions or points. They are suitable for the application of lower rotating speed, higher load, shock loads, harsh working conditions and those positions where it is hard to access.

In this design, the number of rollers are the biggest in all the bearings types. This kind of bearing is designed to bear heavy load. In the same width, compared with traditional cylindrical roller bearings with cages, this bearing is capable of bearing extremely high load capacity and also save space. But it also have shortcomings like bear relatively lower rotating speed and higher internal friction. For every kind of cylindrical roller bearings, there are oil grooves and oil holes on the outer rings. <br> <br>Full complement cylindrical roller bearings contain single row and double row. According to different internal designs, they can also be divided into NNC, NNCL, and NCF series. <br> <br>For the NNC series, it is a non-seal bearing. The outer ring is whole-set split one which is fixed by locking plate. Therefore, the outer ring is not able to bear axial loads. The outer ring is the same with one rib which acts as axial locating in two directions. There are three ribs on the inner ring. Three lubrication grooves and oil holes on lying on the outer ring. Lubrication is oil in general. <br> <br>For the NNCL series, it’s also non-seal bearing without ribs on the outer ring. There are three oil grooves and holes on the outer rings, and three ribs on the inner rings. One fixed ring between two-row rollers on the center of the outer ring can prevent the rollers from falling out. This type allows a certain axial replacement between axle and housing. Therefore, they usually act as free-end bearings. <br> <br>For the NCF series, it can be one rib or no rib with a locking ring on the outer ring. The axial clearance “S” guarantees the axial replacement between axle and housing. <br> <br>Feature of full complement cylindrical roller bearings <br> <br>High radial load capacity <br> <br>High stiffness <br> <br>Separable and exchangeable <br> <br>Longer service life <br> <br>Application fields <br> <br>Tooling machine, steel and metal process, gearbox, port equipment etc <br> <br>As one of the largest bearing manufacturers, we will do our best to meet all the needs of customers.
