Angular Contact Ball Bearings
GMN angular contact bearings (spindle bearings) are expertly crafted for speed, precision, & accuracy.
Radial Ball Bearings
GMN radial ball bearings are versatile, great in small spaces & when axial loads move in both directions.
Other Bearing Brands
We know that not every application requires super, high-precision bearings. We stock other industrial parts from quality brands.
Complete Sprag Clutch Units

No RPM Limit FE 8000 Series
No built-in ball bearing support. Has no RPM limits & Supports high torque needs: 609 to 14,060 Nm. Bore (ID) sizes: 38.09 to 220 mm (1.499 to 8.66 in)
Backstopping Clutch with Mounting Tab
This heavy-duty clutch (aka a hold-back clutch) is good for high torque operations and ensures motion freezes in place. Bore (ID) sizes: 15 to 40 mm. (0.59 to 1.73 in)
Roller Ramp Clutches
Designed for HEAVY-DUTY applications that require tough durability.
CF Seals
The best protection for your bearing. Easy to install with a simple “drop-in” next to your bearing. No added space needed. CF seals offer 100% sealing efficiency against splashing liquids.
L Seals
Protection against low contamination & splashing liquids.
M Seals
Designed with grooves in the outer ring to offer more protection (than our L-type seal) against contamination and direct spray liquids. Liquid gets pushed out through outer grooves when in rotation.
S Seals (Gap Seals)
Our GMN Gap Seals are plastic and a great choice for washdown applications, such as food conveyors and food manufacturing facilities
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.
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.
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.
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.
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.
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.
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.
"GMN Bearing USA has the best lead times in the industry, and you always follow through on your delivery commitments. What you say really is what you get, and then some! An added bonus is that you guys offer Manufacturer Certificates of Conformance, which are crucial for Aerospace applications."
