Also known as roller-element bearings, roller bearings work under the same principle as ball bearings and serve one primary function: carrying loads with minimum friction. The difference between ball and roller bearings is shape and construction. The former use balls, while the latter use cylinders, such as cross roller bearings and linear roller bearings.

Roller-element bearings contain single or double rows of rollers. For instance, double-row roller bearings significantly improve radial load-carrying. Besides, the utility of these bearings in various shapes and sizes allow for transmissions of both radial and axial loads with reduced friction.

Timken bearings are quick and easy to install and manufactured to OE standards. Their expert construction makes them tough to beat in terms of reliability and durability. Using high-quality steel alloys they are incredibly strong and dependable.

A roller bearing is a type of rolling-element bearing that uses a cylinder (roller) instead of a ball. In general, the cylindrical bearings allow for greater radial loads. They are made to handle heavier loads than ball bearings.

Tapered Roller Bearings have tapered inner and outer ring raceways as well as tapered rollers. They are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The projection lines of the raceways meet at a common point on the bearing axis  to provide a true rolling action and therefore low frictional moments during operation. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle α. The size of the contact angle, which is usually between 10° and 30°, is related to the calculation factore the larger the value of e, the larger the contact angle.

Bearing Features:

Low Friction :

• The optimized roller end design and surface finish on the flange promote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear. In addition, the bearings can better maintain preload and run at reduced noise levels. 

Long Service Life:

• The crowned raceway profiles of basic design bearings and the logarithmic raceway profiles of SKF Explorer bearings optimize the load distribution along the contact surfaces, reduce stress peaks at the roller ends and reduce the sensitivity to misalignment and shaft deflection compared with conventional straight raceway profiles.

Enhanced Operational Reliability:

• Optimized surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film. 

Consistency Of Roller Profiles And Sizes:

• The rollers incorporated in SKF tapered roller bearings are manufactured to such close dimensional and geometrical tolerances that they are practically identical. This provides optimal load distribution, reduces noise and vibration, and enables preload to be set more accurately. 

Rigid Bearing Application :

• A single row tapered roller bearing is typically adjusted against a second tapered roller bearing. By applying a preload, a rigid bearing application can be achieved. 

Running-in Period With Reduced Temperature Peaks :

• Tapered roller bearings typically have a running-in period, during which a conventional design tapered roller bearing experiences a significant amount of friction, resulting in wear. This effect is noticed as a temperature spike. With SKF tapered roller bearing designs, friction, frictional heat and wear are significantly reduced, provided the bearings are mounted and lubricated correctly.

Separable And Interchangeable:

• Depending on the design, tapered roller bearings are separable and components of same-sized bearings are fully interchangeable. For example, single row tapered roller bearings are separable , i.e. the inner ring with roller and cage assembly (cone) can be mounted separately from the outer ring (cup). This facilitates mounting, dismounting and also maintenance inspection routines. 

Spherical roller thrust bearings are of separable construction, The shaft washer is assembled with the cage and a number of asymmetrical spherical rollers and has to be used along with a housing washer having sphered raceway. During mounting, the rings are to be fixed on to their respective seats – shaft washer on the shaft and housing washer on to the housing and then they have to be put together carefully They are manufactured in multiple series.

The raceway of the housing washer is at an angle with it’s ais of rotation, so as to be able to allow the rollers to remain in touch with it. As a result, a spherical roller thrust bearing is capable of carrying both a radial as well as an axial load. Spherical roller thrust bearings – because of their internal geometry – are capable of accommodating certain amount of misalignment. However, they can take axial loads only from one direction, and may need to be used in pairs in Back-to-Back or Face-to-Face arrangement, if thrust load from both the directions are to be carried.

Spherical roller thrust bearings are capable of compensating misalignment and shaft deflection.

The bearings are manufactured in normal accuracy. However, bearings with higher running accuracy can also be supplied.

Rolling bearings support and guide rotating or oscillating machine elements – such as shafts, axles or wheels – and transfer loads between machine components. They provide high precision and low friction and therefore enable high rotational speeds while reducing noise, heat, energy consumption and wear. Rolling bearings are cost-effective and exchangeable machine elements that typically follow national or international dimension standards.  Explore our wide assortment of rolling bearings, accessories and services that best meet your specific performance needs.

A thrust bearing, a type of rotary bearing, rotates between parts reducing friction and is designed to support an axial load (mostly in low-speed applications). It is the axial bearing that permits rotation between parts.

Needle bearings are heavily used in automobile components such as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel drive vehicle typically has at least eight needle bearings (four in each U joint) and often more if it is particularly long, or operates on steep slopes.

Tapered roller bearings are designed so that the imagined conical apices formed by the raceways of the inner and outer rings and the rollers all converge at one point on the bearing axis. The trapezoidal tapered rollers used as the rolling elements are guided by a large rib on the inner ring.
