Installation Guide for a GMN Complete Sprag Clutch Unit

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

Complete units FP/FPD/FN/FND 400

Tolerances:

outer ring with press fit hub D = H6
inner ring with press fit (FP/FPD) shaft d = h5
inner ring with keyway (FN/FND) shaft d = js6 (k5)

Keyway specifications according to DIN 6885, Bl.1 (P9) with back clearance.

Machine parts, in which Free-wheel Clutches are pressed in or on, can be of ferrous or nonferrous material. If you are considering using nonferrous material please contact our technical staff first.

For pressed in or on Free-wheel Clutch rings no retainers are necessary for axial or radial security. The inner rings with keyway (type FN and FND) have to be secured in the axial direction only, if the pressed on outer machine part (gear or lever) is not axially secured. When mounting Free-wheel Clutches with bearings do not apply pressure to bearing balls.

After installation a radial clearance between C2 and C5 will be reached. To create a clearance of C2 you should produce your shaft at the highest point and your housing at the lowest point of the allowed tolerances.

Attention: Please take care for total cleaning of Free-wheel rings and mating parts before press fitting (no grease particles left in the press fit area).

Lubrication: Series type FPD 400 and FND 400 are shipped oil lubricated for lifetime. Series type FN 400 and FP 400 are shipped rust protected – not lubricated.
