Product Description
Type ASNU is a roller type freewheel non-bearing supported. Bearings are required to support axial and radial loads. Lubrication and sealing must also be provided by the installation. Nominal outer diameter is the same as a series 63.. ball bearing.
A typical arrangement is to install this type alongside a bearing within the same location tolerances, as shown on the following page. The inner race is keyed to the shaft. The outer race has positive n6 tolerance, to give a press fit in a H7 housing. Additional side notches in the outer race provide for positive torque transmission.
If the housing is to K6 tolerance, use of the notches is not necessary, but the housing must be strong enough to not expand after assembly. This design can accept an axial misalignment of inner and outer race of ± S/2.

 MOUNTING EXAMPLE


Applications example
 
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.
