Deep groove ball bearing is the most common rolling bearing,its structure is simple and easy to use. It is mainly used to bear radial load, it also can play the role of angular contact bearing and bear the connected load in radial and axial direction when the radial play of bearing is increased.
Cylindrical roller bearings are available in many designs, dimension series and sizes. The majority are single row bearings with a cage. Single and double row full complement bearings (without cage) complete the standard assortment for general engineering.
The tapered rollers (with larger spherial end) of these bearings are guided precisely by the integral flanges of the washers (shaft washer and housing washer) with raceways.
Thrust ball bearings consist of two precision chrome steel washers (ring) and a ball complement spaced by bronze retainer. They can be supplied with or without radius ball grooves in the rings.
Self aligning ball bearing mainly have two structures, inculidng cylindrical and tapered, and it has two rows of balls and a common concave sphered raceway in the outer ring.
Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis.
Spherical roller bearings use rollers that are thicker in the middle and thinner at the ends; the race is shaped to match. Spherical roller bearings can thus adjust to support misaligned loads.
Needle bearings have a large surface area that is in contact with the bearing outer surfaces compared to ball bearings.
This type of bearings is separable. The spherically formed outer ring raceway can make selfalignment. There fore ,if there is deflection of the shaft,it is automatically corrected.
This type of bearing is separable and can carry heavy axial loads. They are single directions bearings and can only accommodate axial load in one direction.They can’t limit the dispalcement in radial.
Needle roller thrust bearings are fitted with a form-stable cage to reliably guide and retain a large number of needle rollers.
Tapered roller thrust bearings enable axially very compact bearing arrangements to be produced which can carry very heavy axial loads, are insensitive to shock loads and are stiff.
Pillow block bearings are mounted bearings that are used to provide load support for a rotating shaft’s axis. Their mounting surface is on a line parallel to the axis of the shaft.
The ceramic ball bearings is mainly made of silicon nitride,rconia or alumina,it has many advantages,such as long useful life,high speed ,self-lubrication, high steel ,low friction,light weight,special electrical and magnetism resistance,wear and corrosion resistance,maintenance free when working,especially high and low –temperature application,etc.
A joint bearing in which a rolling member has been designed in such a way that relative to the inner race track and outer race track representing a circular arch, four contact points are obtained, the rolling member is associated with a central cylindrical portion and carrying portions which adjoin it at both ends
Slewing bearings is a bearing that can accommodate large axial load, radial load and overturning moment.
