Adjustable ring gages are a common solution for this application. Solid rings remedied the problem. Customers have reported that they no longer have this problem and benefit from reduced calibration frequency. Today, both adjustable and solid ring gages fit in the manufacturer s needs, bringing benefits in ranges of cost, durability and performance with no difference to verify product conformity. But that is where the difference begins.
Solids have improved integrity, are easier to calibrate, weigh less and have greater longevity.
Each manufacturer must determine whether the benefits outweigh the difference in price. Solids are not for every application. But, when the cost differential is in an acceptable range, buyers now have an excellent alternative to adjustables. The locking assembly and splits of adjustable rings add to the weight of the product. Adjustable rings need to be calibrated with a set plug.
