Ring Gauges

A ring gauge is used to check external diameters on cylindrical objects, as well as calibrating other gauges or standards such as calipers, inside micrometers or bore gauges. Generally, they are cylindrical rings made of a stable material such as steel, with a precision finished interior surface and a known tolerance. Depending on the tolerance, they fall within a range of the following graded levels: XXX, XX, X, Y, Z, and ZZ, with the XXX being the highest grade having the smallest tolerances.

There are a few ways that ring gauges are utilized: either as a master or set ring, or a go or no go gauge. As a go-no-go gauge, they are simply used to check that a cylindrical piece is within tolerance, by offering a reference check as to whether or not that piece fits through the space. As master gauges, and setting gauges (or setting discs), they are used to calibrate dimensional tools. They also come in a variety of configurations, such as spline ring gauges, or thread ring gauges.

Did you know... the precision measurement group at Cross was founded in 1939 by our current CEO's grandfather, Jim King. That's a whole lot of calibration!
Did you know... A fingerprint weighs about 50 micrograms. We know, we weighed it! The residue left from a finger can actually make a difference in weight results which is why we wear gloves when we calibrate weights. For reference, a sheet to paper is about 4.5 grams, that’s 4.5 million micrograms.
Did you know… Cross Company is an ESOP (Employee Stock Ownership Plan). Our ESOP started in 1979 and as of 2006, we are a 100% employee owned! Learn more about our ESOP and how that benefits both team members and our customers.
