Introduction to the types of bearings, there are more types than you can imagine!
Bearings are widely used as an important part of modern machinery. Bearings are generally made up of an inner ring, outer ring, rolling element and cage. For sealed bearings, together with lubricant and a seal (or dust cover), these are all the components of the bearing.
Needle roller bearings: Needle roller bearings are equipped with slender rollers and are therefore radially compact. When their inner diameter and load carrying capacity are the same as other types of bearings, their small outer diameter makes them particularly suitable for bearing constructions with limited radial mounting dimensions. Needle roller bearings can be made without inner rings or needle roller and cage assemblies depending on the application. The journal surfaces and housing bore surfaces used with the bearings can be used directly as the inner and outer rolling surfaces of the bearings. Shaft or shell hole raceway surface hardness, processing accuracy and surface quality should be the same as the bearing circle, in order to ensure the bearing capacity and running performance and with circle bearing the same. Use combination needle roller bearing is by the needle roller bearing and thrust bearing bearing unit, small volume, compact structure, high rotary accuracy, in bearing high radial load at the same time, but also can bear a certain axial load. Combined needle roller bearings are widely used in textile machinery, metallurgical machinery, machine tools, printing machinery and other mechanical equipment, which can make the mechanical system design very compact and dexterous.
Spherical ball bearings: in the two raceways of the inner ring and with a spherical raceway between the outer ring equipped with drum-shaped roller bearings, the outer ring raceway surface curvature and bearing the same, so with the same spherical ball bearing alignment function. When the shaft and housing are bent, they can be adjusted automatically without increasing the burden on the bearing. Spherical roller bearing can bear radial load and axial load in two directions, spherical ball bearing radial bearing capacity is large, suitable for heavy load and shock load. Bearings with a tapered inner diameter can be mounted directly or mounted on a cylindrical shaft using a fastening sleeve or dismantling cylinder. The cage is stamped from sheet steel and made of polyamide. Spherical ball bearings are suitable for bearing heavy and shock loads, low noise motors, automobiles, motorbikes, metallurgy, rolling mills, mines, petroleum, paper, cement, sugar and other industries and general machinery.
Spherical roller bearings: spherical roller bearings are drum-shaped roller assembly in the inner ring with two raceways and with a spherical raceway between the outer ring of the bearing. Spherical roller bearings have two rows of rollers, with high radial bearing capacity, mainly bear any direction of the radial load and axial load, especially suitable for heavy load or vibration load work, but can not bear pure axial load. This kind of bearing outer ring raceway for spherical, good alignment performance, can compensate for coaxiality error. Spherical roller bearing has two rows of symmetrical spherical roller, outer ring has a common spherical raceway, inner ring has two and bearing axis into a certain angle tilt raceway, adjusting performance is good.
