Custom Special Bearings | GMN Bearing USA

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

Besides high precision angular contact bearings and radial deep groove ball bearings, we can manufacture special bearings which are matched bearings with spacers and oil supply rings or we can manufacture bearing units ready to install.

Bearing Material Choices

You can choose between:

Standard bearing steel
Special material like: High temperature tool steel or non-corrosive steel AISI440C

Standard bearings with different dimensions are available on request.

The cages of these bearings are produced in accordance to the inner design of the bearing and correspond to the application. We use either standard materials or special materials like VESPEL, TORLON, aluminum, bronze or NiBe2.

Bearing Units

We offer complete bearing units ready to install.

We also offer various coatings like solid lubricants or protection layers. Please look at our vacuum technology page for more details.

Please note: To manufacture and ship special bearings or bearing units, we require economic lot sizes.

Technology

For certain applications, it is impossible to use standard ball bearings due to limited space, special lubrication, guidance and sub-functions that often do not allow additional machine parts.

When this happens a standard bearing has to be adapted to a specific application.

Our “Special Bearings” department assists in these adaptations and are fully experienced. We produce bearings to our customer’s specs plus any associated components, like spacers with and without oil feeding, complete bearing units and respective sub-assemblies.

The special bearings and bearing units are produced on special machine tools with the utmost precision. Because of the present machinery at GMN, the production is limited to the following dimensions:
