Deep groove ball bearing, is the most widely used kind of rolling bearing. The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cage, its characteristics are small friction resistance, high speed, can be used to bear radial load or radial and axial at the same time the role of the combined load on the machine, can also be used to bear axial load on the machine, such as small power motor, automobile and tractor gearbox, machine tool gear box, general machines, tools, etc.
Tapered roller bearings belong to the separated bearing, bearing inner and outer ring have tapered raceway. These bearings are divided into single row, double row and four row tapered roller bearings according to the number of rollers installed, and other different structure types. Single row tapered roller bearings can bear radial load and single direction axial load. When the bearing bear radial load, will produce an axial force, so when another can bear the opposite direction of the axial force bearing to be balanced.
Spherical roller bearings have cylindrical and tapered bore, tapered tapered bore taper 1:30 and 1:12 two, this tapered bore bearing with a tightening sleeve or withdrawal sleeve, can be tapered bore spherical ball bearing convenient, rapid assembly in the light shaft or step machine shaft.
The main function of wheel hub bearing is to bear the weight and provide precise guidance for the rotation of the wheel hub, which is subject to both axial and radial loads.
The thrust ball bearing is designed to withstand thrust loads at high speeds and consists of a washer-like collar with a raceway groove for ball rolling. Because the collar is seat cushion shape, therefore, the thrust ball bearing is divided into flat bottom seat cushion type and spherical spherical seat cushion type two types. In addition, this kind of bearing can bear the axial load, but can not bear the radial load.
Thrust roller bearing is used to bear axial load mainly combined axial and radial load, but the radial load shall not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has lower friction factor, higher speed, and has aligning performance.
Angular contact ball bearings can withstand both radial and axial loads. It can work at higher speed. The larger the contact angle, the higher the axial load carrying capacity. Contact angle for the radial plane of the ball and raceway contact point line and bearing axis between the vertical line of the angle. High precision and high speed bearings usually take 15 degrees contact angle. Under the action of axial force, the contact angle will increase.
Cylindrical roller and raceway are linear contact bearings. Large load capacity, mainly bear radial load. Rolling body and the sleeve retaining edge friction is small, suitable for high-speed rotation. According to the sleeve with or without retaining edge, can be divided into NU, NJ, NUP, N, NF and other single row cylindrical roller bearings, and NNU, NN and other double row cylindrical roller bearings. The bearing is a structure with separable inner ring and outer ring.
Spherical ball bearing has cylindrical hole and tapered hole two kinds of structure, keep frame material has steel plate, synthetic resin, etc.. Its characteristic is the outer ring raceway is spherical, with self-aligning, can compensate for the error caused by different heart and shaft deflection, but its inner and outer ring relative tilt shall not exceed 3 degrees.
