Setting rings: applications and characteristics

Setting ring is a gauge used in industrial production to control and adjust the size and shape of other parts. TruThread's Setting rings are highly precision manufactured because their use depends on ensuring the proper geometric parameters of the products they control.

Setting rings are used as a means of checking manufactured parts for compliance with given standards and specifications. When manufacturing parts, it is important to ensure the correct size and shape so that the finished product is of high quality and able to perform as intended. In this way, the setting rings help to check the parts for defects and determine whether they meet the requirements.

When inspecting parts, workers simply insert the test part into alignment with the setting ring. If the part fits or engages properly with the mounting ring without excessive clearances or overlaps, then this indicates that the part has been manufactured to the required specifications. Otherwise, if the part does not match the snap ring, corrective action is required to achieve the desired performance.

Specification: DIN 2250

Materials: Hardened & Stabilized steel (AISI 01/ EN 31) for rings with a diameter of 3 mm - 300 mm. Tungsten carbide only for rings with a diameter of 4 mm - 60 mm

All steel Setting rings are cryogenically treated to improve their geometric stability. This process involves processing at very low temperatures so that they are less susceptible to deformation or dimensional changes due to external factors, temperature fluctuations or loads. Such rings will remain more stable and reliable in use.

Whenever the roundness is within above specified tolerance limit, the actual diameter is marked on the setting ring. The actual diameter shall be within the above specified permissible deviation limit from the specified diameter value.
