Stieber Clutch was founded in Munich in 1937 and is now a medium-sized company employing 140 people at its locations in Heidelberg, Germany, and Garching near Munich. The core business of Stieber Clutch is the design and production of drive elements for mechanical engineering systems. The main strength of Stieber Clutch lies in the development and production of overrunning clutches and backstops that transmit torque via friction.

Stieber Clutch product quality:

Stieber Clutch products are calculated using the FVA method and tested and verified on Stieber Clutch test benches. Stieber Clutch has test machines with torque capacities of up to 700,000 Nm. During idling operation, devices with bore diameters of up to 600 mm can be tested at speeds of up to 1,500 rpm. The modern equipment in the Stieber Clutch quality department enables independent simulation tests for the nuclear power industry. Thanks to this, Stieber Clutch has obtained certifications such as Areva and complies with the KTA 1401 standard.

Stieber Clutch market applications:

Highly engineered Stieber Clutch solutions are widely used in major markets such as printing, energy, material handling, textiles, automotive, agriculture, marine, steel, and entertainment facilities, in applications such as conveyors, printing presses, pumps, fans, gearboxes, crushers, mixers, turbines, looms, seeders, balers, lifeboat davits, and winch thrusters.

Stieber Clutch main products:

stieber clutch self-contained one-way clutches

The one-way clutch is self-supporting via integrated plain bearings or ball bearings; in most cases, this version is delivered fully sealed with an internal lubrication system. Models AV, CSK, GFR, AL, FSO, SMZ, RIZ.

stieber clutch built-in one-way clutches

The one-way clutch includes only the inner ring, outer ring, and clamping elements. Bearing support and lubrication must be provided by the customer's design. Models AS, ASNU, AE, NF RSCI. In some cases, the quote includes the clamping element, model DC.

stieber clutch  ramp-and-roller one-way clutch

In this type of freewheel, both races are cylindrical. The wedges mounted in the cage have an active profile that ensures engagement or disengagement depending on the relative motion of the raceways. The design of the wedges and cage can be adjusted to achieve significantly different characteristics from one model to another. For example, models with permanent contact or no contact during overrunning operation are available. Models DC, RSCI, RIZ.

stieber clutchRoller ramp one-way clutch

This freewheel features a cylindrical outer ring and internal rollers arranged on ramps. Springs and plungers ensure permanent contact between the various elements for instant torque transmission. This robust, reliable, and versatile design can be used as an overrunning clutch, indexing clutch, or check valve. Note: If the outer ring overruns, **overspeed is possible. For this reason, it is particularly suitable for high-speed overrunning clutch applications with dual drives. This design is recommended for use as an indexing clutch.
