|
| Rotorseals & Quick Release Valves |
|
|
|
The various ROTORSEALS (rotary union) manufactured by Gummi permit the transfer of a variety of mediums such as gases, liquids, into or out of the open end of the shaft.
Most all pneumatic drum clutch / brake elements operate with a through – the – shaft... more |
| Couplings |
|
|
|
The earliest of all the Gummi products were couplings. Gummi manufactures a wide variety of couplings designed specifically to protect the more critical elements in a series of power transmission components. The couplings are there to absorb shock and... more |
| Air Clutches & Brakes FM (CM-Marine Clutch) |
|
|
|
The Gummi type FM element was originally designed primarily for marine applications for use on reverse reduction gears. In addition to all the benefits of having an integral rim / tube construction, the FM element utilizes ventilated friction shoes for... more |
| Air Clutches & Brakes FKR (ER) |
|
|
|
The Gummi type FKR element is commonly referred to as a coupling due to the fact that it has a neoprene rubber facing in place of the standard friction shoes as seen in other elements. The rubber facing offers the advantages of both a flexible and disconnect... more |
| Air Clutches & Brakes (Type FK Element (CB)) |
|
|
|
The FK was the first constricting style drum clutch to be introduced to the power transmission industry. Due to its reliability and simplicity in design, the Gummi type FK element is well suited as a clutch or brake in a wide variety of high-speed, low... more |
| Air Clutches & Brakes (Type FKT Element (VC)) |
|
|
|
Considered to be the workhorse or drum clutches, the Gummi type FKT element was designed principally for high torque / high thermal capacity applications on heavy duty equipment. The FKT element offers the versatility of the type FK, while also providing... more |
| Bi-Directional Clutches |
|
|
|
Available in six sizes, the Formsprag RL Clutch is a sprag type no-back which permits transmission of driving torque from input to output shaft in both directions of rotation, but restrains any feedback torque of the driven load from rotating the output... more |
| Backstopping Clutches |
|
|
|
Formsprag Clutch offers a number of Special Design Backstop clutches, in addition to many standard offerings which can be used, where reverse rotation must be positively prevented. The availability of both Sprag and Ramp & Roller Designs assures a wide... more |
| Indexing Clutches |
|
|
|
Through the wide variety of designs offered by Formsprag Clutch and Stieber Clutch in both Sprag and Ramp & Roller Designs virtually any application can be met where reciprocating motion applied to the driving race is transformed into intermittent motion... more |
| Overrunning Clutches |
|
|
|
All Formsprag/Stieber clutches described in this catalog are essentially “overrunning” clutches, i.e., they will drive in one direction but overrun (freewheel) in the other direction.Through the wide variety of designs offered by Formsprag Clutch and... more |
| Flexible Couplings |
|
|
|
The torque is transmitted via a compressed elastic intermediate ring. This ring absorbs shocks and torsional vibrations, is resistant to oil and largely insensitive to temperature.

| Keyless Locking Devices |
|
|
|
TYPE AS
AS outer clamping sets safely fasten disk shaped components such as gears or drive pulley's to a shaft. Depending on the requirements, installation utilizes threads in the installed drive component or through holes in the drive component and... more |

| Miniature Couplings |
|
|
|
Backlashfree, torsionally rigid, flexible and maintenance-free all-steel coupling. It has been developed for drive systems with small, low torque drive systems.
... more |
| Torsionally rigid |
|
|
|
The couplings are used whenever torsion between machines being connected is either not required or not desired, but where machine-shaft misalignments must be compensated for.
