One Way Clutch Bearings

One Way Clutch Bearings

New One Way Bearing series by Boca Bearings. Drawn cup needle roller clutches have a small radial section height and are also commonly known as One Way Bearings or Anti-Reverse Bearings. This design uses the same small radial section as drawn cup needle roller bearings which make better use of available space. The units are compact, lightweight and operate directly on a shaft; they are also suitable for transmitting high torque.

One Way Bearings are designed to transmit torque between the shaft and housing in one direction and allow free motion in the opposite direction. Proper mounting is easily accomplished with a simple press fit in the housing. Clutches and clutch and bearing assemblies are offered both in inch and metric series. One Way Bearings without bearing assemblies are indicated by suffix: HF/FC/RC. One Way Bearings with bearing assemblies are indicated by suffix: HFL/FCB/RCB.

SPECIAL NOTES

• HFL series has two integral radial bearings arranged on both sides of needle roller clutch. They can therefore support radial forces in particularly space-saving bearing arrangements.
• Plastic springs (HFL...KF) are available for some sizes.
• Partially knurled outer ring (HFL...R) is available upon request.
• A special tool is suggested when assembling the clutch and bearing assembly. For details please contact our engineers.
• Only after the clutch and bearing assembly has been pressed into the hole of the housing, the drawn thin-walled outer ring could then obtain its final dimension and geometric accuracy.
• The transmissible torque and the stresses which can be taken by the housing are subject to the material and the wall thickness of the housing, and such data is needed upon enquiry.
• The clutch and bearing assembly can be normally used in temperature range from -30°C to 120°C. For the working environment above 70°C, oil lubrication is recommended.

ONE WAY BEARING DESIGN FEATURES

• Torque can be transmitted by either the housing or the shaft.
• Torque is positively transmitted by rollers that wedge against interior ramps.
• Transition from free motion to lock occurs with minimal backlash or lost motion.
• Available as clutch-only or as a clutch and bearing assembly.
• Clutch-only units should be used with external radial support to hold the shaft and housing.

ONE WAY BEARING APPLICATIONS

• Paper moving for copiers, fax machines, paper towel dispensers, etc.
• Exercise equipment
• Appliances
• Two-speed gearboxes
• Rack indexing drives
• Converters, non-return devices and transcendental clutches.
• Fishing Reels, RC Cars, RC Helis, RC Engines

INSPECTION OF ONE WAY BEARINGS

Although the outer cup of the clutch is accurately drawn from strip steel, it can go slightly out of round during heat treat. When the assembly is pressed into a ring gage or properly prepared housing of correct size and wall thickness, it becomes round and properly sized. Direct measurement of the outside diameter of a drawn cup assembly is an incorrect procedure. The proper inspection procedure is as follows:

1. Press the assembly into a ring gage of the proper size as given in the tabular data.
2. Gage the bore with the specified plug gages of the proper size, as given in the tables of dimensions.

- The locking plug is rotated to insure lockup when the clutch is operated at low limit shaft and is mounted in a high limit housing strong enough to properly size

  • Sprag Type One Way Clutch Bearing (CSK)

    The CSK One Way Bearing Series is a sprag type freewheel integrated into the 6200 radial bearing series. The internal part of the bearing is protected by a seal but additional seals are recommended especially when the working temperature exceeds 50°C. All CSK One Way Bearings are equipped with chrome formed sprags that increases the over-run life several times. Torque transmission is ensured by a press fit assembly into a rigid outer housing and onto a shaft with an N6 tolerance. Initial bearing radial clearance is set at C5 and is reduced if using the press fit as specified.

    The CSK One Way Bearing Series has a small radial section height and is also commonly known as a One Way Bearing or Anti-Reverse Bearing. One Way Bearings are designed to transmit torque between the shaft and housing in one direction and allow free motion in the opposite direction. In addition to the basic CSK model, type CSK..P features a keyway on the inner race and CSK..PP features a keyway on both the inner and outer race. For this reason it can be keyed to a shaft.
