Spherical Roller Bearings

SGL Bearings Ltd can provide more than 1,000 different part numbers for spherical roller bearings across many brands, cage types and internal clearances making well over 100,000 different part number combinations.

Call us on 01302 315144 or email us sales@sgl-bearing.com with your enquiry.

Whether you are looking for one spherical roller bearing for your own repair job or are looking for us to hold consignment stocks for vendor managed inventory then we have the flexibility to work to suit your requirements. With over 20 years knowledge of working in China we can manufacture bespoke spherical roller bearings or purchase standard bearings and manage the quality control or we can work with our partners to manage stock of tier 1 brand spherical roller bearings from manufacturers such as SKF, NSK, FAG, Koyo, NTN and SNR.

Spherical Roller Bearing Identification and Assistance

We can help you to identify your spherical roller bearings. Metric and inch sized bearings are constructed the same, just the dimensions change. Usually the bearing part number is printed via laser marking on the race of the bearing.

If there are no markings on the bearings then we just need to take some measurements, Ideally with vernier calipers and we'd need 3 measurements from the bearing to be sure to match it up correctly.

We would take the inner diameter of the bearing which we refer to as dimension d
We would take the outer diameter of the bearing which we would refer to as dimension D
We would take the depth of the bearing through the middle which we would refer to as dimension B

Once we have dimensions d, D and B then have all of the information that we need to be able to identify your spherical roller bearing.

Types of spherical roller bearings

There are multiple types of spherical roller bearings, each suitable for different applications. These include :
Standard spherical roller bearings : These bearings have an angular adjustment of up to 2° to compensate for misalignment. They consist of two rows of rollers with an inner ring and an outer ring. Usually the cage will be made from steel however the cages can also be made from machined brass or from a polyamide plastic such as PA66.

Swivel-joint roller bearings : These bearings are used for vibration machines and vibratory screens such as on road rollers. They are used on machines and in equipment that are subjected to the most severe stresses and support both high loads and high speeds. They are well suited to operating in adverse conditions and can support angular mis-alignments of up to 0.15°

Split spherical roller bearings : Split spherical roller bearings are well suited to situations where replacing the bearings is difficult due to time or space constraints. Because they are split, they can often be fitted without any further dismantling of the machinery that they are being installed on which significantly shortens machinery downtimes.

Axial spherical roller bearings : Axial spherical roller bearings contain just one row of rollers and the cage holds the rollers in place much in the same way as with a tapered roller bearing. These bearings can be dismantled and as such, the components can be fitted separately if required.

Sealed spherical roller bearings : Becoming increasingly popular as it allows a combination of the high load bearing capabilities of spherical roller bearings as well as the sealing performance from other series of bearings, these sealed spherical roller bearings can be used in more challenging environments and are becoming popular in agricultural applications as well as in casting plants, elevators and conveyor systems.

Spherical roller bearings – Did you know ?

Spherical roller bearings are used in Ferris wheels ? probably the most famous of which is the London eye with over 3 million visitors per year. The wheel is supported by large spherical roller bearings weighing a few tons each and with diameters of approximately 2 metres. The London eye itself weighs over 2,000 tons. Spherical roller bearings were selected because of their high load carrying capabilities as well as their ability to handle misalignment.
