There are also a number of shield and seal options that protect the friction surfaces from debris or contaminants; these include (2RS) denoting two rubber seals and (ZZ) which denotes two metal shields. Both the metal shields and rubber seals can be used individually protecting just one side of the bearing or both depending on your requirements.

Type 2: Roller bearings: Consisting of Tapered Roller bearings which are great for axial loads due to their shape, Needle Roller Bearings , Spherical and Cylindrical.

There are two main types of bearing and both consist of an inner race way, outer race way and the rolling element. Bearings are typically used to limit the radial and axil movements of rotating and reciprocating equipment whilst facilitating minimal friction against rotation.

Bearingtech are able to supply bearings in a range of manufacturers including FAG, SKF, NSK/RHP, DUNLOP and Timken as well as supplying unbranded or budget bearings.

In this article, we discuss the main early warning signs to look out for that could indicate an emerging fault with your bearings.

Heat during operation is generated through a build up of friction – an issue that ball bearings are specifically designed to avoid. Above usual levels of heat are, therefore, a common sign of friction building up between the bearing surfaces and should be addressed quickly before it causes overheating and damage. Excess heat can have a detrimental effect on other components in your system if it is not addressed promptly.

A good ball bearing will be designed to minimise vibrations during operation, with a smooth transfer of motion and kinetic energy. Vibrations, therefore, can be a sign of a problem with your bearings. For example, if the ball bearing is not properly aligned or is damaged or worn, it will start to vibrate unusually during operation, even at its specified speed and load.

Even a small lubricant leak is a red flag of a potential problem, often the result of a damaged seal on a bearing allowing lubricating oil to leak out from inside the component itself. The immediate result is less protection for the bearing and an increased risk of further wear and tear over time. A lubricant leak could progress into additional symptoms, such as excessive heat, vibration, and noise, and the issue should be addressed as quickly as possible.

Taper Roller Bearings: These are different in that they are tapered in order to with stand axial loads. These bearings do not come in shielded or sealed options and are roller rather than ball bearings. 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 buy a set of numbers and sometimes letters depending on the manufacturer.

Measuring your bearing: Most bearings are measured in three ways, the inside diameter or (ID), the outside diameter or (OD) and the width or (W).

Spherical ball bearings are intended to rotate in all directions, accommodating both radial and axial loads. Rough or sluggish rotational movement may be the sign of wear and tear or physical damage, so if you notice a change in the range of movement when using your machinery, we recommend inspecting each component carefully to identify any potential issues.

You will also need to know what clearance you require. There are two main clearances which are; normal clearance with no suffix and C3 greater than normal clearance.

Although high quality ball bearings are generally durable components – especially when purchased through a reputable supplier and produced by a world leading brand, such as Dunlop – these components can and do develop faults through regular use. Recognising the first signs or symptoms of ‘bad’ ball bearings will enable rapid repair or replacement before excess friction and waste heat leads to mechanical damage or premature failure in your application.

It is important to note that our bearing measurements are all done in the following order: Inside diameter (ID) x Outside diameter (OD) x Width (W).

How to identify or measure your bearing. Most bearings will contain identifying marks and these are usually a series of numbers and some times letters. Identifying a bearing can be complicated at times but this page is designed to help simplify the process.

One of the tell-tale symptoms of a failing bearing is excessive or unusual noise during operation. In particular, a growling, squealing, or humming noise could indicate insufficient lubrication, poor alignment, or the early stages of a mechanical fault.

C3 clearance will allow faster running speeds and higher temperatures without failure. There are further clearances that can be ordered so please get in touch if you have special requirements these are shown below: sales@bearingtech.co.uk
