At GMN Bearing USA, we build relationships, not just sell precision components. We know how our parts fit into your larger picture. We have a people-first culture, and we’re united by our passion for quality and a shared commitment to our partners. We can’t sell a precision product without tailored service, which is why we offer engineering expertise with our onsite mechanical engineers.

We pride ourselves on our expert-level support & rapid response times. We are here to make a difference.

What We Do

GMN Bearing USA is the #1 supplier of German-made high precision bearings, clutches & seals in North America. GMN, based in Nuremberg, Germany, has been manufacturing industrial precision components since 1908.

GMN Bearing USA opened its doors in 1994, and we’re proud of what we do – helping engineers, spindle rebuilders, & distributors find the right high-precision component… Fast.

We’re committed to building long-term business relationships and our technical sales associates see projects through, from initial concept to prototype to production.

Our Facilities

The moment GMN parts leave our warehouse, we’re your partners, seeing you across the finish line. If you have issues? We’re talking. We know about overload, improper mounting, brinelling, contamination, misalignment, lubrication, corrosion, fatigue. If you’ve got it, we’ve seen it. And we know how to help.

Lucky for us, GMN parts are the best in the business. Every single bearing, clutch & seal that leaves GMN’s manufacturing plant in Nuremburg, Germany is hand-checked. It doesn’t make it out of the door without GMN’s rigorous testing and careful inspection to ensure constant uniformity.

GMN prides itself on products free of defects. When it comes down to microns, there is just no room for error.

GMN is Conflict Mineral Free, ISO 9001 certified, ISO 14001 (Environmental certification), RoHS certified & compliant.

The GMN Difference

P4+ Bearings

p4 bearings

GMN knows that super precision bearing tolerancing is critical and this is especially true on the inner diameter (ID), outer diameter (OD), and width (W). The fits on the shaft and housing can have large effects on how bearings perform.

GMN marks every P4+ bearing with the exact value of the ID, OD, and W deviations. In addition to that, all GMN P4+ bearings have a circle laser etched on the inner ring that indicates where the high point of the inner ring is.

This way, multiple bearings can be arranged to optimize the balance of the bearing set.

 

P2 Runouts

People use precision angular contact bearings because of the need for tight manufacturing tolerances that translate to bearing performance and life. Of the manufacturing tolerances, the runouts, or the running tolerances, are the most critical values for bearing performance - i.e. running accuracy.

For this reason, all GMN P4+ angular contact bearings are manufactured with P2 runouts. That means that for the cost of a P4 bearing, GMN’s customers are receiving the dynamics of a P2 precision bearing.

Universal Matching

Many bearing manufacturers push to have bearing pairs that are optimized for a specific bearing arrangement, back to back, face to face, etc. For GMN, the universal matching tolerances are so consistent that GMN’s angular contact bearings can achieve similar benefits as using matched sets.

For this reason, GMN stocks almost exclusively universally matched bearings making it easier for the customer to get a working bearing cross from another brand.

It also means that customers don’t need to buy bearings as an optimized pair, triplex set, or quad set. Since the individual bearings are universally ground, individual pieces can be purchased to make up the required set.

 

No Grease Fees

no grease fee

GMN sees greasing bearings as a service and key aspect of the partnership with our customers. We use a precise method to add just the right amount of grease in a clean and controlled environment to ensure success of the lubrication in the application.

Too much or too little grease can cause issues for any application, including but not limited to shorter application life and high temperatures. The trust that our customers have in GMN to lubricate or relubricate their products is of the utmost importance.

A single human hair can decrease the life of an application, which is why GMN is nothing short of persnickety about its relubrication processes. Because of all of these reasons, GMN doesn’t even consider charging for this value added service.
