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.

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.

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.

Bore diameter will determine what size pistons you need. It is also an important measurement used to calculate Engine Displacement.

If your block needs machined, the shop will hone the bore. When the machining is done, they will tell you the final measurement.

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).

The size of the cylinder bores will impact an engine's fuel efficiency and power output. Larger cylinders usually mean more power. They also require more fuel.

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.

Type 1: Ball bearings: Are great at dealing with radial loads and come in a few varieties, Deep Groove, Angular Contact, Self Aligning and Thrust bearings.

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

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.

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).

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.

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.

Cylinder bore diameter is the measurement across the inside of the bore. It can be listed in either inches or millimeters.
