Customer Comments

“During the development of an extreme-temperature motor for an oilfield pumping system that was to operate a mile and a half underground we encountered temperatures that defeated all of our existing bearing designs.  USA Tolerance Rings’ Hastelloy rings solved the problem by providing tight fit between dissimilar parts across a very large temperature range while enduring high pressures, vibration, and temperatures that destroyed all of our other bearing designs.  They’re also easy to assemble, which is a benefit to any manufacturing process.  Thanks for a great product!” – John Knapp, Senior Product Engineer, Baker-Hughes Centrilift in Claremore, Oklahoma 


“We have used USA Tolerance rings since 1995.  These are easy to work with and very economical.  We designed them into 3 different products.  The Tolerance rings hold the bearings and maintain the integrity of the aluminum housing.  By protecting the housings, we have a superior product that outperforms any competitive products and prevents costly repairs or replacement of equipment.  We strive to serve every customer with great products as efficiently as possible and USA Tolerance rings produces that support.– Craig Parma, President and CEO of Texas Pneumatic Tools   Reagan, TX
