Retaining Rings & Circlips
Shaft rings to DIN 471 and bore rings to DIN 472, quoted on nominal diameter, thickness and groove dimensions. The ring is half the specification; the groove it sits in is the other half, and a ring picked on diameter alone can sit loose in a groove cut to a different standard.

What decides the price
In order of impactDIN 471 goes on a shaft, DIN 472 goes in a bore. The two are not substitutes in either direction.
Diameter locates the ring, thickness is what the groove has to accept. Both are on the part number.
Groove width and depth come from the standard, not from the ring. A non-standard groove needs a ring made for it.
Worth checking before you order
It will not seat, and forced it deforms and then leaves. The two standards exist because the loading is opposite.
Rings deform on removal. Reusing one is a common cause of a shaft walking under load.

Questions
Can you supply the matching pliers?+
Yes. Rings and circlip pliers are quoted together so the range matches the tool.
Do you have groove dimension tables?+
Per standard, yes, and we confirm against your drawing where the groove is non-standard.
Send the specification, not the product name.
Grade, size, thread standard and coating are what a quote is built from. A product name alone produces a price that changes twice before the order.
