Drawn cup needle roller clutches have a very small radial section height. This makes optimum use of the available space and allows compact designs to be achieved. These clutches are suitable for transmitting high torque. They are normally used for converters, non-return devices and transcendental clutches. 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.

Designation & Size
[HFL]: metric drawn cup roller clutch and bearing assembly with steel springs. Bore size from 8mm to 35mm.
[FCB]: Torrington metric drawn cup roller clutch and bearing assembly with steel springs. Bore size from 8mm to 35mm.
[RCB]: Torrington inch drawn cup roller clutch and bearing assembly with steel springs. Bore size from 3/8inch to 1inch.

Note
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.
