Ball Bearings
Overview
Ball bearings are rolling-element bearings that use balls to maintain the separation between the bearing races.
The ball bearing reduces rotational friction and supports radial and axial loads by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary while the other is attached to the rotating assembly, like a hub or shaft.
Features
Angular Contact
Angular contact ball bearings have offset raceways that support combined radial and axial loads. A larger contact angle increases axial load capacity. Single-row bearings support axial loads in one direction and are commonly paired for loads in both directions.
Angular contact ball bearings use 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. This means 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.
Deep-Groove
In a deep-groove radial bearing, the race dimensions are close to the dimensions of the balls that run in it. Deep-groove bearings can support higher loads.
Tapered Roller Bearings
Overview
Tapered roller bearings are uniquely designed to manage both thrust and radial loads on rotating shafts and in housings.
Features
Tapered roller bearings consist of four interdependent components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer. The taper angles allow the bearing to handle a combination of radial and thrust loads. The steeper the cup angle, the greater the ability of the tapered roller bearing to handle thrust loads.
Cylindrical Roller Bearing
Overview
A cylindrical roller bearing uses straight cylindrical rollers, so the load is carried along a line instead of a point. That gives a high radial capacity and lets the bearing run faster than most other roller bearings. It is not the highest radial capacity of every roller type. A spherical roller bearing is usually the heavier duty choice.
Features
Four common styles are N, NU, NJ, and NUP. The difference is which ring has ribs. N and NU take radial load only and let the shaft move end to end. NJ takes radial load and a limited axial load in one direction. NUP takes radial load and a limited axial load in both directions.
Spherical Roller Bearing
Overview
A spherical roller bearing has two rows of barrel-shaped rollers running in a spherical outer race. The inner ring can tilt a few degrees when the shaft and the housing are not perfectly aligned. It carries a heavy radial load and axial load in both directions.
Features
The self-aligning shape keeps the bearing working when a shaft bends or a housing is slightly out of line. These bearings are used on conveyors, gearboxes, fans, and other heavy equipment. This is not a spherical plain bearing. A spherical plain bearing has no rollers and is used where a joint has to pivot.
Needle Roller Bearing
Overview
A needle roller bearing uses rollers that are long and thin. The cross section is small, so it fits where a ball bearing or a standard cylindrical roller bearing would be too tall.
Features
The thin rollers put more contact area in a small bearing, so the radial capacity is high for the space it takes. A radial needle bearing has the rollers parallel to the shaft. A thrust needle bearing is flat, with the needles laid out in a radial pattern, and it takes axial load. A caged needle bearing spaces the rollers with a cage. A full complement needle bearing has no cage and more rollers, which raises the load it can carry and lowers the speed it can run.
