Start with the part number. Most bearings, seals and belts have one stamped or printed on them, and you can type it straight into the search bar.

If the number has worn off, measure the part using our measuring guide, or contact us with a photo and details of what it's fitted to. We'll identify it.

Take 6205-2RS as an example. The 6 means it's a deep groove ball bearing, the 2 is its size series, and the last two digits give the bore. From 04 upwards, multiply by five to get the bore in millimetres, so 05 is a 25mm bore. 00, 01, 02 and 03 are 10, 12, 15 and 17mm.

The letters after the number describe seals and clearance. 2RS means rubber seals on both sides, ZZ or 2Z means metal shields on both sides, and C3 means greater internal clearance than standard, often used where bearings run hot.

Rubber-sealed bearings (2RS) keep out water and fine dust better, so they suit dirty or wet conditions. Metal-shielded bearings (ZZ) have lower friction and suit higher speeds in cleaner environments. If you're replacing a bearing, match what was fitted unless you know the conditions have changed.

Oil seals are sized by shaft diameter, housing bore and width, in that order. A 30x47x7 seal fits a 30mm shaft in a 47mm housing and is 7mm wide. Measure the shaft and housing rather than the old seal's inner lip, which stretches in use.

Measure the pitch, which is the distance between the centres of two neighbouring pins. Then check whether it's British Standard (such as 08B) or American ANSI (such as 40). They can share the same pitch but aren't interchangeable, so measure the roller diameter too, or send us a photo.

Yes. We stock V and wedge belts, cogged belts and timing belts, along with pulleys, sprockets and taper lock bushes. Our measuring guide explains how to identify a belt with no code.

Very likely. We only list part of what we can supply, so if you can't find it on the site, contact us with the part number, measurements or a photo and we'll look into it.

Items cut to your chosen length or made to your specification, such as timing belts, roller chain, hose, tubing and pipe. The product page will say if an item is cut to order.

No, unless it's faulty. Because it's made to your specification, it can't be cancelled or returned once cut. Your legal rights for faulty items still apply. If you're unsure of the size, call us before you order.
