Roller Bearing

Roller bearings allow withstanding more significant radial load because the cylindrical shape produces a linear contact surface. Dispersion radial load on the linear roller bearing of the larger contact area than ball bearings provides a much larger volume of similar size. Innovative design allows further modification of roller bearing can bear greater axial force. A conveyor belt and large equipment are needed for the most typical roller-contact bearing platforms.

Types of Roller Bearings

Cylindrical bearings: These linear roller bearings have unparalleled performance in terms of radial load capacity, making them ideal for heavy equipment and large operations. Usually formatted inline configuration, for example. Single row cylindrical roller bearing types for standard applications and up to four rows of cylindrical roller bearings for extremely high radial load requirements.

Tapered roller bearings: These are designed to provide balanced performance for large axial and radial forces. The sharp geometry is a crucial design attribute, which provides a large roller bearing contact surface and the ability to carry higher loads. Tapered roller bearings are usually used in row configurations to increase load capacity.

Spherical roller bearings: These linear roller bearings provide consistent performance for the most demanding applications. In situations where extreme speeds, non-optimal lubrication, misalignment, or other performance challenges are expected, spherical roller bearings provide the best results when subjected to heavy radial loads.

Thrust bearings: These roller bearing types are optimized to withstand high axial (thrust) loads. Usually, thrust bearings are used for high-speed applications, and the load is generally lighter. There are many different variants of thrust bearings, some of which allow greater loads at reduced speeds.

Cross Roller Bearing: The crossed roller ring is a roller bearing with high rotation accuracy, which can bear loads in all directions. Because it has orthogonally arranged cylindrical rollers, it can withstand loads in all directions.

Needle roller bearings: Small cylindrical bearings of the needle roller bearing type ensure the smallest possible friction profile.

Application of Roller Bearing


Roller bearings are used to replace sliding motion with low friction, rolling motion in rotating applications. The main types of roller bearings are cylindrical, spherical, and conical. Generally speaking, roller bearings provide a higher load capacity than ball bearings of the same size.

Roller bearings are used for heavy-duty medium-speed applications. Potential applications for spherical and cylindrical roller bearings include power generation, oil fields, mining and aggregate processing, wind turbines, gear drives, and rolling mills. Single row tapered roller bearings are used in machine tool spindles, gear reducers, automotive drive axles, transmissions, vehicle front wheels, differential and pinion configurations, conveyor rollers, machine tools spindles, and trailer wheels.

FAQ

The tapered roller bearings in 2 parts (cup and cone) are measured by shaft diameter, bore diameter, and bearing thickness. The cup goes in the bore, and the cone goes on the shaft.

They are made up of cups and cones and are available in both metric and imperial sizes. Taper roller bearings are still measured in the same way, Inside diameter x Outside diameter x Width and are also identified again by a set of numbers and sometimes letters depending on the manufacturer.

TFL can supply bearings to a range of manufacturers, including FAG, SKF, NSK, KOYO, IKO, and Timken, and provide unbranded or budget bearings.

What are the best roller bearings? There are many types of bearings, such as deep groove balls, spherical rollers, tapered roller bearings, cylindrical rollers, needle roller bearings, etc. No brand can be good at making all of these. Some brands are good at certain types of bearings; for example, SKF is good at spherical rollers (their invention), Timken is good at tapered rollers (also their invention), Schaeffler is good at needle rollers, NSK is good at precision Jack joint.

Choosing the best roller-bearing brand, in the final analysis, isn’t easy, with good after-sales service, reasonable quality, and a good sales network.

If I really recommend the best roller bearing brand manufacturer, I would recommend KOYO bearing, a bearing brand from Japan (learn more). As an authorized agent of Koyo bearings, TFL can provide a full range of bearing types and provide competitive prices.

A spherical roller bearing is a rolling-element bearing that permits rotation with low friction and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring. The misalignment is possible due to the spherical internal shape of the outer ring and spherical rollers. Despite what their name may imply, spherical roller bearings are not truly spherical in shape. The rolling elements of spherical roller bearings are mainly cylindrical in shape. Still, they have a (barrel-like) profile that makes them appear like cylinders that have been slightly over-inflated (Excerpt from Wikipedia).

What are spherical roller bearings used for? Spherical roller bearings are commonly used in agricultural machinery such as combine harvesters, blowers, paper machines, textile machinery, woodworking machinery, moving wheels and drive shafts of overhead cranes, and many non-agricultural applications.

What is a tapered roller bearing? Tapered roller bearings feature tapered inner and outer ring raceways with tapered rollers arranged between them, angled, so the surface of the rollers converges at the axis of the bearing. These bearings are unique in that, unlike most bearings that can handle either axial or radial loads, they can handle large amounts of load in both directions.

How do they work? Tapered roller bearings can roll freely on the mating surface of the shaft and a hub, which serves to prevent friction, heat, and wear of grinding action of the metal. Usually held by a cone-bearing inner ring together, the rolling bearing inner race having a conical surface and a flat surface to the inner diameter of the slide shaft.

The outer ring is the opposite, the inner surface is tapered, and the outer shell is flat. The cone angle of the bearing allows the component to handle radial and axial loads. Axial load is usually called thrust load.

How to use tapered roller bearings? A typical example is a wheel hub bearing. The wheel hub bearing is a tapered bearing used to bear two loads on the mating surface. Radial loads come from the vehicle’s weight, and axial or thrust loads are generated by the helical gears of the differential, which tend to push each other. This push generates a thrust load in the shaft, which is then transmitted to the angular surface of the tapered bearing through the tapered raceway.
