Roller bearings

Welcome to our category for roller bearings! Here you will find a wide selection of high-quality roller bearings known for their precision, reliability, and performance. Roller bearings, like ball bearings, are crucial components in a variety of machines and mechanical systems.

Roller bearings are a special category of rolling bearings. Unlike other types of bearings, such as ball bearings, roller bearings have elongated rollers as rolling elements. These rollers provide a larger contact area between the inner and outer rings, resulting in higher load carrying capacity. Therefore, they are particularly suitable for applications where heavy loads occur, such as in machinery, industrial plants, vehicles, and other rotating systems.

Depending on specific requirements and operating conditions, there are various subcategories of radial roller bearings, such as tapered roller bearings, cylindrical roller bearings, spherical roller bearings, needle bearings, barrel roller bearings, and toroidal roller bearings. Each subtype has its own design features and advantages to meet different applications:

Tapered Roller Bearings: Tapered roller bearings consist of inner and outer rings with tapered rollers in between. They are particularly suitable for combination loads, as they can withstand both radial and axial forces. However, it should be noted that they can only accommodate unidirectional axial loads, thus requiring precise alignment and careful adjustment. By arranging two tapered roller bearings in a mirror image, both sided axial loads can be accommodated.
Many manufacturers offer paired single-row tapered roller bearings that are preassembled in a tapered roller unit with a defined axial clearance or specific preload. In addition, there are double-row tapered roller bearings, which are also offered as preassembled bearing units consisting of an inner ring with two rows of rollers in an X arrangement and a multi-part outer ring.
Tapered roller bearings are a specialized type of bearing that plays an important role in various industrial sectors because of their ability to withstand both radial and axial forces
Cylindrical Roller Bearings: Cylindrical roller bearings have cylindrical rollers positioned between inner and outer rings. They are characterized by high radial load capacity and are suitable for applications with high speeds. Depending on the arrangement of the edges, cylindrical roller bearings can withstand certain axial loads that can act unilaterally (edge on one side) or bilaterally (edges on both sides). Cylindrical roller bearings are commonly used in motors, gearboxes, and rolling mills
Barrel Roller Bearings: Barrel roller bearings are similar to Spherical Roller Bearings, but are designed as single-row bearings. They have a special shape of inner and outer rings. The rollers are barrel-shaped, allowing for high load capacity and compensation of alignment errors. Barrel roller bearings are used in heavy machinery, mining equipment, and wind turbines
Spherical Roller Bearings: Spherical roller bearings have two rows of barrel-shaped rollers running in a common spherical inner ring. This construction allows for compensation of alignment errors and expansions of the bearing housing.
Spherical roller bearings are non-separable and can transmit very large radial forces. They are also limited in their ability to accommodate bilateral axial loads. Most spherical roller bearings are supplied with lubrication bores and lubrication grooves as standard to enable efficient lubrication. Spherical roller bearings are suitable for lower to medium speeds. They are often used in areas with high vibration or impact loads, such as pumps, fans, and vibrating machinery
Needle Bearings: Needle bearings are specifically designed for applications with high loads in limited space. They have elongated cylindrical rollers with a large length-to-diameter ratio compared to the diameter. Needle bearings are used in automobiles, motorcycles, textile machinery, and other applications where high load capacity is required
Toroidal Roller Bearings: Toroidal roller bearings, also known as CARB bearings (Compact Aligning Roller Bearings), have a toroidal shape of rollers and inner rings. They offer high load capacity and compensate for alignment errors, and can accommodate axial displacements. Toroidal roller bearings are often used in applications with low friction and high speeds, such as in pumps, compressors, and textile machinery

Designation system - rolling bearings (ball bearings, roller bearings)

Different manufacturers use various designation schemas to describe the specifications and characteristics of their rolling bearings. These designations include crucial information such as dimensions, load ratings, tolerances, and special features of the bearings. In addition to basic designations, there are prefixes and suffixes that provide additional information about modifications and specific attributes of the bearings. For example, well-known manufacturers like SKF, FAG, and NSK each have their own codes and designation systems, enabling the quick identification of the suitable bearing for a specific application. Understanding these designation schemas, including the prefixes and suffixes, is important for making the right choice in bearing selection.
To provide you with better guidance, we have created an overview that explains the suffix codes used in the designations of bearings by leading manufacturers and their meanings. You can find this overview here: Rolling bearings designation system.
