NACHl's self-aligning roller bearings are a common and important industrial part, widely used in a variety of mechanical equipment and construction machinery. It is mainly composed of an outer ring, an inner ring, a roller, a cage and other components, and supports the rotating and swinging shaft through rolling friction. Aligning roller bearing has large radial load capacity and high axial load capacity, as well as excellent self-aligning performance, and can adapt to the relative tilt and axial change between shaft and seat when working.

Double-row tapered roller bearings have many advantages in structure and performance, so they are widely used in industrial production.New domestic modelsOld domestic modelInner diameter (mm)Outer diameter (mm)Width(mm)Cr(kN)Cor(kN)Grease lubrication speed (r/min)Oil lubrication speed (r/min)Weight (kg)302027202E15351114.913.412000160000.053302037203E17401220.821.89000120000.079302047204E20471428.230.58000100000.126302057205E25521532.237700090000.154302067206E306217.543.250.5600075000.231302077207E35721754.263.5530067000.331302087208E4080186374500063000.422302097209E45851967.883.5450056000.474

1.Cylindrical hole· With two rows of steel balls and a curved raceway in the outer ring, self-aligning ball bearings can be actively aligning· and can accept the point of view error between the shaft and the bearing seat. It is suitable for the working condition that simply shows the shaft deflection and the shaft error caused by different centers· Friction is the lowest of all rolling bearings· has only a small temperature rise even at high rotational speeds.2.

Angular contact ball bearing has high limit rotational speed, they can carry radial load and axial load simultaneously, they can also withstand purely radial load. The axial load carrying capacity depends on the magnitude of contact angle and increases with increasing contact angle. Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools, for which high running accuracy is required.Single row angular contact ball bearings can carry axial load acting in one direction only.

Double row angular contact ball bearings correspond, in their design and operation, to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space.

It uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race. Angular contact bearings better support "combined loads" (loading in both the radial and axial directions) and the contact angle of the bearing should be matched to the relative proportions of each.

Double row deep groove ball bearing:Design: With two balls, these bearings can handle a higher load capacity than a single row of bearings.Application: They are suitable for bearing arrangements where the bearing capacity of a single row of bearings is insufficient, for example in heavy industry applications.Features: Double-row bearings are slightly wider than single-row bearings, but offer better load distribution and improved reliability for demanding applications.Both single-row and double-row boring deep groove ball bearings are designed with high-quality materials to ensure durability an

Aligning roller bearings have two rows of rollers, mainly bearing radial loads, but also can withstand axial loads in either direction. It has high radial load capacity, especially suitable for heavy loads or dynamic loads, but cannot withstand pure axial loads. This kind of bearing outer ring raceway is spherical shape, so its aligning performance is good, can compensate for the coaxial error.Self-aligning roller bearings are divided into two different structures according to the roller cross section shape: symmetrical spherical roller bearings and asymmetric spherical roller bearings.

Typical applications include Combine harvesters, balers, seeder, tillage and lawn and garden machinery. This range of bearings for agricultural machinery complements our large stock of housed bearings units.Agricultural Ball Bearings are used in nearly every piece of machinery you see.

Tapered curler bearing refers to the radial thrust kind rolling bearing whose rolling physique is a tapered roller. There are small cone angles and giant cone angles. The small cone Angle usually bears the radial and axial mixed hundreds ordinarily primarily based on radial loads, regularly used in double, reverse installation, the internal and outer seat rings can be established respectively, and the radial and axial clearance can be adjusted throughout set up and use.

Product Description:Can manufacture mechanical shell, frame and other structural components.

Tapered roller bearings are suitable for bearing radial loads, unidirectional axial loads and radial and axial combined loads. The axial load capacity of tapered roller bearings depends on the contact Angle α, that is, the Angle of the outer ring raceway, the greater the contact Angle α, the greater the axial load capacity. Generally tapered roller bearings do not allow Angle errors, but the surface of the roller and raceway can be specially designed to allow 2'~4' Angle errors.
