The GMN Difference

GMN Bearing USA’s ABEC 7 high precision ball bearings are made for high speed and heavy load applications.

GMN angular contact bearings (spindle bearings) are expertly crafted for speed, precision, & accuracy.

GMN radial ball bearings are versatile, great in small spaces & when axial loads move in both directions.

We know that not every application requires super, high-precision bearings. We stock other industrial parts from quality brands.

Our one-way sprag clutches are great for applications with low to high torque capacity.

Includes built-in ball bearing support. Supports HEAVY loads & has a high torque capacity: 53 to 588 Nm. Bore (ID) sizes: 10 to 60 mm (0.393 to 2.362 in)

Includes built-in ball bearing support. Supports MEDIUM loads & low to medium torque capacity: 53 to 267 Nm. Bore (ID) sizes: 17 to 40 mm (0.669 to 1.57 in)

No built-in ball bearing support. Good for large orders & low to high torque needs: 1 to 2673 Nm. Bore (ID) sizes: 2 to 240 mm (0.078 to 9.448 in)

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)

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)

Designed for HEAVY-DUTY applications that require tough durability.

Our non-contact labyrinth seals are the first line of protection for bearing systems.

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.

Protection against low contamination & splashing liquids.

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.

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 are focused on quality in everything we do. Our engineering expertise and precision products are the best in the industry.

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

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, this 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.
