VS, VSNU, and VF Roller Ramp Clutches

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

The VS, VSNU, and VF roller ramp clutches are rust protected and can be used with a variety of GMN ball bearing series. To learn more about the differences in these Series, contact our team! When using these series, take extra precautions to avoid axial misalignment and thrust loads.

VS Series

The VS Series is rust protected and fits shafts 8-80mm. This clutch is best used with our radial ball bearing 6200 series.

VSNU Series

Similarly to the VS Series, the VSNU Series is rust protected and fits shafts 8-80mm. However, this series can be used with our ball bearing 6300 series.

VF Series

GMN’s VF Series roller ramp clutch fits shafts 8-60mm and is rust protected. Use this series with our ball bearing 6400 series.

Torque Transmission

Torque transmission from the shaft to the clutch inner ring is obtained by a keyway connection.

Torque transmission from the housing to the clutch outer ring is attained by press fit or key connection to the outer ring face key.
