The different versions offered in this product group are based on a combination of a bearing and a idler wheel within the dimensional envelope of the considered bearing series.
The most popular model (CSK..) is built on the basis of the bearing series 62..... Sizes are available from 8mm to 40mm bore.
These units are available in many different versions:
- plain with ZZ type seal
- plain with 2RS type professional seals
- keyway inside with ZZ or 2RS type seals
- keyway inside and outside with ZZ type seals
A few other models are based on other suppliers of bearings series like 59.. and 60....

Free wheels with cams to be incorporated with obstruction radial reduced.
Couples from 48 to 460 Nm for tree of diameter 20 with diamètre50.
They count industrial rollers of blocking between a line of professional balls and rollers, to combine dynamic heads, static, axial and radial.
Without maintenance, autonomous, lubricated with grease for normal conditions of use, they are used to lock a step back or to place from one drive to the other in a kinematics to multiple order.
External dimension identical to the bearings specifications series 59.

| Free professional wheel with a cage with contact elements running on races primarily measured in inches |
|
In this product group only the clamping elements are offered under the form of a sprag cage (or retainer). It is one assembly that can be mounted between races that are manufactured directly in the customer’s parts. Technical specifications for the manufacturing of the races must be met. Of course the professional clutch races must be maintained concentric by existing shaft bearings suppliers that also support all axial and radial loads.
The system must also provide lubrication and sealing. |

RINGSPANN freewheels are an essential design element in the machine and automotive industry as well as aviation technology. Concerning know-how and technology RINGSPANN belongs to the leading manufactures of the world. The freewheel as an automatic driving element is preferred to conventional solutions because of its decisive advantages offered in respect of
operating safety
economics
higher degree of automatisation. |
|
SIAM-RINGSPANN irreversible lock enables free driving of any machine element in both directions of rotation but locks any reverse torque from the the driven element to the driver.
Application:
Fastening devices for steerable professional wheels
Rudder and control-surface locks in ships and aircraft
Non-return locking in shut-off and control valves manufacturers
Locking adjustable devices in position
Securing hatches and windows
Ensuring that railway signals and points remain at their settings
Ensuring that settings are held in hydrostatic pumps
Cam adjustments
Locking and manual adjustments of gate opening and closing mechanisms
Locking of trolleys in hoist manufacturer equipment
Securing aerials against angular shifts
Locking horizontal ball-bearing mounted spindles manufacturers
Locking professional manipulator equipment |

The transmission is involved in the 2 directions of rotation and is locked in position. The origin of the movement can be manual or electric.
The bidirectional transmission involves the transmission towards the right-hand side or the left. If the movement of entry ceases, the irreversible one locks the transmission in the position of stop and the movement of exit is neutralized in the 2 directions.

The different versions of this product group offer the one way clutch function only. It is generally based on inner and outer races with the clamping elements in between. These units must be built in systems where the professional clutch races can be maintained concentric by existing shaft manufacturer of bearings that also support all axial and radial loads.
The system must also provide lubrication and sealing. |

| Free professional wheels with rollers, with flanges for assembling, self centring or requiring centring, used ad overspeed, non-return, intermittent feed. |

Magna Torque (MT) for Backstopping and Indexing
Hilliard’s line of overrunning clutches is economically priced and ideally suited for backstopping and gearbox applications. Custom designs and rapid prototyping are available.
Roller Ramp (MTR) for Professional clutch Couplings, Dual-Drive & Turning Gear
There is almost no wear during freewheeling operations in the Hilliard roller-ramp designed clutch because industrial rollers are free to rotate between the outer member and the inner cam. Typical applications for this clutch are blowers, pumps, professional fans, conveyors and forming rolls.
Enclosed Overrunning Clutches
Hilliard’s enclosed overrunning clutch incorporates superior MTR design in a totally enclosed package. Designed for power transmission operations, this clutch is totally contained in a stationary housing for constant protection from hostile environments or washouts.
High-Speed Overrunning Clutches
The Hilliard high-speed overrunning clutch provides positive engagement and high torque on demand. Featuring a unique roller-ramp design, the clutch when engaged transmits power via the precision-machined cam and roller assembly connected to the input shaft. Typical applications include hydraulic, electric, and pneumatic turbine starters; turbine drives, and turbine auxiliary drives.

Placed between 2 energy sources, the oversteer one couples or disconnects whatever the differential speed.
It is a relayage simple, instantaneous, autonomous, without control.
To 360.000 Nm, the active elements are with slopes, cams.
Under casing, lubricated with oil or grease.
During launching out of high-speed, the oversteer one disunites and protects slow speed. |

Drawn cup roller clutches are one-way clutches comprising thin-walled, drawn outer rings with a series of ramps on the inside diameter, plastic cages, industrial springs and needle rollers. They can transmit torques in one direction and are radially compact. The roller clutches are available with and without a bearing specification assembly.
Drawn cup roller clutches give very precise indexing, since individual spring retention of each needle roller ensures constant contact between the shaft, needle rollers and the clamping surfaces. They allow high indexing frequencies due to their low mass and therefore the low moment of inertia of the clamping elements. They also have a low free-wheeling frictional torque.
Drawn cup roller clutches can be used in a wide variety of applications, for example as indexing elements, back-stopping clutches or overrunning clutches. The drawn cup roller professional clutch fulfils the overrunning or holding function as appropriate.
