Thick grease will retard roller engagement and can cause individual rollers to slip, possibly overloading any engaged rollers. If an interference fit is used for the inner ring, the outer ring should be mounted with a clearance fit. Opposite 15, in the nominal bore diameter column for metric series bearings in Table 5, will be found the following information: Direct measurement of the outside diameter of a drawn cup assembly is an incorrect inspection procedure.

If you have any needs of gluing, sealing, supressing noise or fast, cheap and effective methods of repairing breakdowns, please contact us. In the lock mode shown in the drawings below, the relative rotation between the housed clutch and callowe shaft is opposite to that in the overrun mode. Brand Loctite Teroson Bonderite.
In cwlowe the total torque load on a clutch, it is essential to consider the torque due to inertial forces developed in the mechanism, in addition to the externally applied torque.
If desired, specify on order. Outer Ring Rotation, Oscillating Motion.
For general information regarding lubrication of drawn cup bearings refer to page E The metric bearing user should note that addition of these values to the h6 tolerances given in tables of dimensions results in a standard j6 tolerance.
Through bored and chamfered housings are preferred. The manufacturing tolerance of these bearings is one-third that of the precision bearings.

Low strength housings non-steel, sintered metals and some plastics may be entirely satisfactory in lightly loaded applications. The sketches on these pages illustrate some of the many possible uses. Sealed drawn cup bearings are intended to retain grease or nonpressurized oil within a bearing while also preventing contaminants entering the raceway area.
The controlling dimensions are in inches. In addition, there can be other identifying letters which cover special modifications.
The mounted clutch or clutch and bearing assembly engages when the housing is rotated relative to the shaft in the direction of the arrow and LOCK marking LOCK stamped on the cup. For long fatigue life, the shaft raceway, must have a hardness equivalent to 58 HRC ref, ASTM Eand ground to the recommended diameter shown in the tables of dimensions.
We are a typically engineering company which is preferring technical rather than only purely commercial aspects of the marketing process of Loctite products. When using adhesives, care must be taken to keep the adhesive out of the clutches and bearings.
To remove a drawn cup bearing from a through-bored housing, use a tool similar to the installation tool illustrated, but without the stop. For bearings of nominal metric dimensions, the recommended mounting dimensions shown on the tabular pages are consistent with ISO N7 housing bore and h6 inner raceway o. An integral assembly within a single drawn cup, in which two roller bearings straddle the clutch.
The steel spring type clutches have proven dependability at rates up to or engagements per minute. The bearing designation prefix letters HK indicate that, the bearing is of nominal metric dimensions.
Inch to metric and metric to inch conversions are listed for the convenience of the user, but the designer should understand that the controlling dimensions are in inches for nominal inch assemblies and millimeters for nominal metric assemblies. Load ratings are given in pounds-force: When ordering an extraprecision bearing, add the prefix letter G to the bearing designation. The case hardened cups have a long fatigue life, but must be properly supported to realize this benefit. Inch-metric conversions given are for the convenience of the user.
These are tabulated on pages to of the drawn cup section. Either the member housing the clutch drives the shaft in one direction, or the shaft can drive the clutch and its housing member in the other direction.

Angular displacement between the shaft and housing increases as an applied torque load is increased. When applying these clutches, it is important that separate bearings be used adjacent to the clutches to carry radial loads and assure concentricity between the shaft and the housing. Applications involving loads approaching this rating or the tabulated working load, whichever is the smaller, should be referred to the Torrington Engineering Sales Office before a final selection is made.
If you think a special clutch is indicated, please contact your local Torrington representative for a review of your application. Before ordering any clutch and bearing assemblies check for availability. The nominal bore diameter for the bearing, as shown in the table of dimensions on pageis 38 inch. Designation codes for clutches and clutch and bearing assemblies with inch nominal dimensions begin with the letter R.
For inspection purposes, see tolerance tables on page Closer control of valowe clearance would be governed by the users capability of holding housing and shaft raceway dimensional tolerances tighter than the limits shown on the tabular dalowe.
The shaft shoulder diameter adjacent to the inner ring must not exceed the inner ring O. The molded acetal resin plastic cage with integral springs holds its necessary resiliency and strength when the operating temperature within the clutch is kept below F 93C. HK bearing Shaft diameter tolerance 0. Bearings of nominal metric dimensions should follow ISO R7 and f6 tolerance practices.
Bearings with reinforced plastic cages are gwijty use where operating conditions permit. Steels which are modified for free falowe, such as those high in sulfur content and particularly those containing lead, are seldom satisfactory for raceways.
Axial motion between shaft and clutch rollers prevents lockup. City of Torrington – National Center on The drawn cup roller clutch, or the clutch and bearing assembly, must be pressed into its housing. Ksiazka Techniczna Lozyska Wiencowe Documents.
