Not sure which ring you need?
Which standard applies, what the nominal size refers to, and how to measure what you have.
DIN 471, DIN 472 and DIN 6799 explained
Three standards cover almost every metric retaining ring you will meet. Picking the wrong one is usually a matter of measuring the wrong surface, not of choosing the wrong part.
How to measure for a circlip
The ring you pulled out is the least reliable thing to measure. Measure the feature it sits in, and the size falls out of the standard.
Fitting and removing circlips safely
Most circlip failures are fitting failures. A ring that was over-expanded on the way in will not hold, however right the part number was.
Circlip materials and finishes
Carbon spring steel does almost every job. The cases where it does not are predictable, and they are worth knowing before the assembly is closed up.
Cannot identify the part?
Send the shaft, bore or groove dimensions, the ring thickness if you have it, the material and the quantity. If it is an imperial size, an old reference or something outside the listed range, the trade desk will tell you what is needed to identify it.
Listed by specification
Every part shows its standard, nominal shaft, bore or groove size, material and pack quantity, so you can check it against a drawing before ordering.
Straightforward pack pricing
One price per pack, shown on the card and on the product page. No trade tiers to decode, no minimum order value, and tracked uk delivery at a flat £4.95.
No VAT charged
The Maximum Industrial Group Limited is not currently VAT registered, so the price you see is the price you pay. Nothing is added at checkout.
Photographs show a representative part from each standard. Dimensions are governed by the applicable DIN standard rather than by the photograph, so check the groove sizes on your drawing before ordering.
