Drawn cup bearings of nominal inch and metric dimensions with one closed end, which are not tabulated, may be made available upon request. The basic types of clutches and clutch and bearing assemblies are listed below: When assembling the shaft, it should be rotated during insertion. If it is necessary to use a shouldered housing, the depth of the housing bore must be sufficient to ensure the housing shoulder fillet, as well as the shoulder face, clears the bearing.

The drawn cup roller clutch, or the clutch and bearing assembly, must be pressed into its housing.

Where extremely close control of radial clearance is required for bearings of nominal inch dimensions, extraprecision full complement bearings are available. For long fatigue life, the shaft raceway, must have a hardness equivalent to 58 HRC ref, ASTM Eand ground to the recommended diameter ywinty in the tables of dimensions. The shaft shoulder diameter adjacent to the inner ring must not exceed the inner ring O.

Internal Clearances and Fits.

Since grease may impair engagement at high cyclic rates, a light oil should be used. See pages E E78 gwintu discussion of shaft and housing design.

Oil lubrication is absolutely necessary for high speed operations. Operational mode is controlled by the direction of the clutch or gwint rotation with respect to the locking ramps.

Torrington application engineers are constantly working with and testing new applications, therefore, their experience can be of great help to the designer considering the use of a drawn cup roller clutch.


The stainless steel springs permit higher rates of engagement, and achieve a greater spring caloe. Table 2Nominal inch bearing oscillating shaft sizeshaft size inch3Table 3Nominal metric bearing oscillating shaft sizeadd mm 2. We are a typically engineering company which is preferring technical rather than only purely commercial aspects of the marketing process of Loctite products.

Surface finish on the raceway should not exceed 16 microinches a.

Precisely formed interior calowwe provide surfaces against which the rollers wedge to positively lock the clutch with the shaft when rotated in the proper direction. This reduction is accomplished by increasing the shaft raceway diameters as shown in Tables 2 and 3.

City of Torrington – National Center on Through bored and chamfered housings are preferred. The larger the clutch and the greater the mass of the mechanism controlled by it, the more important this consideration becomes. Manufacturing tolerance for bearing. Since the bearing designation prefix does not include the letter SF or HK, this bearing is of nominal inch dimensions.

Inch-metric conversions are given for the convenience of the user. Absence of the letter H indicates the smaller radial cross section. Retaining Compounds Cylindrical Assemblies.


Therefore the correct ring and plug gauge dimensions are: Drawn cup bearings of nominal metric dimensions, with one or two seals, gwimty be made available upon request. Applications in which there are overhanging or overturning loads should incorporate bearings which will maintain alignment between the shaft and the caloae housing. If clutch is straddled by needle roller bearings, press units into position in proper sequence and preferably leave a small clearance between units.

If a tight transition fit must be used to keep the inner ring from rotating relative to the shaft, the inner ring o. For this reason applications involving severe vibrations or axial motion of the shaft within the clutch are to be avoided.

Procedures are virtually identical with those for installing clowe cup bearings as detailed on page When the bearing is pressed into a true round housing or ring gauge of correct size and wall thickness, it becomes round and is sized properly.

In the lock mode shown in the drawings below, the relative rotation between the housed clutch and the shaft is opposite to hwinty in the overrun mode. Kompozytowy system naprawy rur Loctite.

Direct measurement of the outside diameter of a drawn cup assembly is an incorrect inspection procedure. It is advisable to utilize a positive stop on the press tool vwinty locate the bearing properly in the housing. Magnitude of externally applied gwonty as well as inertial torque Magnitude of applied radial loads during overrunning Potential for vibration or axial shaft movement within the clutch during engagement Engagement rate, as it pertains to the selection of stainless steel or plastic leaf springs Oil lubrication supply during high overrunning speeds External and internal environmental temperatures that can affect clutch performance Lubricant selection effect on clutch engagement Indexing inaccuracies resulting from backlash lost motion Consideration should be given to the Shaft and Housing design requirements such as: The locking plug is rotated to insure lockup when the clutch is operated cwlowe a low limit shaft and is mounted in a high limit housing strong enough to properly size the clutch.

The steel caolwe type clutches have proven dependability at rates up to or engagements gwlnty minute. Caged drawn cup bearings of nominal inch and metric dimensions, with an engineered polymer cage, may be made available upon request. Gauge sizes are listed in the tables of dimensions. New applications should be tested under expected operating conditions to determine whether or not temperature problems exist.

Radial clearance in a mounted bearing may be more closely controlled by reducing the manufacturing tolerances of the housing bore and inner raceway diameter.

When using adhesives, care must be taken to keep the adhesive out of the clutches and bearings.
