Features
Internal Freewheels ZZ are sprag freewheels with bearing support and ball bearing properties. The freewheels are supplied grease-filled for normal operating conditions.
The freewheel is assembled into the customer housing, allowing a compact, space-saving solution. The freewheels ZZ are used as:
1.Backstops
2.Overrunning Clutches
3.Indexing Freewheels
Maximum torques up to 480 lb-ft/650 Nm. The torque is transmitted on the inner ring and/or
on the outer ring by press fit or keyway connection. Bores up to 1.575 inch/40 mm.
The following series are available:
The Internal Freewheels ZZ of the sizes ZZ 6201 to ZZ 6207 have the same dimensions as the respective ball bearings of series 62. The series ZZ 2RS and ZZ P2RS have 2RS
seals.
Application example
Two Internal Freewheels ZZ 6206 as indexing freewheels in the drive of the metering roller of a seed spreader. The freewheels are built in an infinitely variable oil bath gearbox. Two cam disks that are off set by 180° are arranged on the gearbox shaft. By means of torque arms, these drive the outer rings of the two adjacent Internal Freewheels, which then gradually turn the metering shaft. The infinite speed settings of the gearbox's drive shaft are executed by means of the respective pivoting of the roller support plate, so that the torque arms can execute lifts of differing amounts.

Mounting
The torque is transmitted on the inner ring and outer ring by press fit. In order to transmit the torques specified in the table, the outer ring must be installed in a housing with an external diameter K. The housing should be made of steel or grey cast iron in minimum quality GG- 20. When using other housing materials or smaller external diameters, we urge you to contact us regarding the transmissible torque. The tolerance of the housing bore D must be ISO N6 and the tolerance of the shaft must be ISO n6.
The permissible operating temperature of the freewheel is - 40°F to +175°F.
Lubrication
The freewheels are supplied grease-filled for normal operating conditions. However, the
freewheels can also be connected to the customer ´s oil lubrication system; this is particularly recommended in the case of higher speeds.

Applications of one way clutch bearing:
Air cleaning plants; Gear Reducers , Conventional and Nuclear Power Plants,Agricultural machines; Automotive Industry, Clay Pigeon Traps , High Voltage Switchgear, Buchet elevators; Compressors; Conveyors; Cranes and hoists; Dry cleaning machinery; Duplicator equipment; Fish net machines; Heat-treatment furnaces; Induced draft fans; Multi-states conveyors; Packaging machinery; Printing machinery; Pumps; Punch presses and feeders; Power plants; Refinery equipment; Speed reducers; Standby power units; Textile looms; Two-speed grinders; Two-speed shiftovers; Washing machines; Wire winding machinery. Rolling Mills, Roller Coaster, Fitness Machines, Industrial Fans, Vertical Pumps
Gear Reducers
Here one-way clutches are used as integral backstops in drive systems for conveyors, industrial fans, pumps, crushers, mixers, kilns and turbines. One-way clutches are also widely used as overrunning clutches in auxiliary or pony drives and dual-drive systems.we offers solutions for long life and maintenance free operation.
Printing Machines
The classic application in printing machines is the inking roller auxiliary drive. But one-way clutches have also been used extensively as indexing devices, to provide an inexpensive and reliable means of achieving a mechanical variable speed drive for the inking roller main drive.
We know-how results in inexpensive, customised solutions even for the most demanding applications.
Conventional and Nuclear Power Plants
R&B backstops are used extensively on pumps used in the primary and secondary cooling systems of power generating equipment. R&B is certified to KT 1401 as an authorised supplier for the nuclear power industry.
Textile Machines
There is a wide range of applications for R&B clutches in textile machinery, especially in circular knitting machines, thread preparation, bobbin winding and looms. In applications using sprag clutches the special Formchrome finish used in our ball bearing series of one-way clutches offers an exceptionally long life in overrunning applications.
Automotive Industry
There is a wide range of applications in the automotive manufacturing sector. Overrunning clutches on conveyor systems and engine test bed starter mechanisms, exhaust fan backstops in spray painting booths. The multiplicity of designs offered by R&B offers the designer the best opportunity to achieve the perfect "fit".
Clay Pigeon Traps
In this common application a one-way clutch is used as a backstop to prevent the arm of the trap "bouncing" back after a launch. The rugged R&B roller-ramp design provides a reliable solution for this demanding but price sensitive application.
High Voltage Switchgear
Here a one-way clutch is used as a backstop to secure the actuating spring pre-load position. The quality and reliability of the chosen R&B product ensures instantaneous applied torque and a firm "latch".
Agricultural Machinery
On seed drills a series of one-way clutches is used as an indexing mechanism to provide an infinitely variable speed drive. One-way clutches are also used for overrunning on round bale presses and as backstops for bulk conveyors and silo extractors. R&B ball bearing series sprag clutches and self-contained designs offer simple and effective solutions for many applications in this industry.
Car Washing Gantries
To avoid damage to vehicles in the event of a drive system failure car washes use overrunning clutches in the horizontal roller drive. R&B ball bearing series and self-contained roller-ramp designs can be very easily incorporated into chain sprockets, timing belt pulleys and other drive elements.
Rolling Mills
In the steel, and other metals industry one-way clutches are used as overrunning drives in roller conveyors. The speed of the conveyed material can momentarily be accelerated without any effect on the main drive.
Fitness Machines
R&B ball bearing clutches have proved dependable and durable in the flywheel assembly of superior quality rowing and stepper machines and novel drive systems in bicycles and manually operated wheelchairs.
Davits (Winches)
R&B one-way clutches are used in combination with brakes to ensure the safe lowering and raising of rescue vessels on ships and off-shore platforms. New industry wide standards are satisfied by R&B design and manufacturing quality.
Bow Thruster
R&B one-way clutches are used as backstops to prevent reverse rotation of the thruster's propeller when not in operation. Units with centrifugally disengaging sprags offer a solution that can be easily incorporated into the drive gearbox and, under drive conditions, operate contact free to ensure a very long operating life.
Industrial Fans
One-way clutches are frequently used in multiple fan installations to prevent non driven fans from "windmilling" in the reverse direction.
Vertical Pumps
Large vertical pumps used in power generating plant cooling systems and for flood control frequently employ a backstop. Larger versions of the R&B high speed backstop are ideal for these applications and may be mounted on the top of the pump or the electric motor.
