Nominal dimensions, load ratings, limiting speeds and other general specifications for extraprecision bearings are the same as for the corresponding B or BH sizes of drawn cup needle bearings. For example, after following the size selection procedure outlined on pages E72 to E76, bearing B is selected, but extraprecision tolerances are required.

The use of caged rollers in inch bearings is indicated by the prefix code letter J. 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. Internal Clearances and Fits. The full complement drawn cup bearing combines maximum capacity and low cost with the advantages of the drawn outer ring.

Identification, Construction, Special Clutches. Although the outer cup of the clutch is accurately drawn from strip steel, it can go slightly out of callowe during heat treatment. Installation procedures are summarized in the following sketches: For example, a bearing with metric nominal dimensions is indicated by the code letter F or HK having open ends and letters BK for closed ends, in the prefix.

They are applying worldwide in all branches of industry.

The recommended minimum housing outside diameters in the tables of dimensions are for steel. The units are compact, light in weight and operate directly on a hardened shaft. An integral assembly gwwinty a single drawn cup, in which two roller bearings straddle the clutch.


Load Ratings are based on a minimum raceway hardness of 58 HRC or equivalent.

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. The surface finish of the housing bore should not exceed microinches, a. The ramps are case hardened to assure long wear life. Kompozytowy system naprawy rur Loctite.

In case the o. Calkwe your Torrington Engineering Sales Office for recommendations. Naprawa i ochrona betonu. Proper mounting is easily accomplished with a simple press fit in the housing. The inward turned lips of the cup are used to mechanically retain the full complement of needle rollers to provide positive radial retention of the rollers even though it may be necessary to remove the shaft repeatedly during the servicing of the mechanism employing the bearing.

The drawn cup roller clutch, or the clutch and bearing assembly, must be pressed into its housing. Inner rings for drawn cup bearings are designed to be a loose transition fit on the shaft and should be clamped against a shoulder.

If clutch is straddled by needle roller bearings, press units into position in proper sequence and preferably leave a small clearance between units. In the lock mode shown in the drawings below, the relative rotation between the housed clutch and the shaft is opposite to that in the overrun mode. These are tabulated on pages to of the drawn cup section.

Clutch lockup depends upon static friction. Projektowanie podzespow osi i waw [20]. Adhesives will not provide proper support in oversized metallic housings. The variation in backlash from one cycle to another is extremely low. See page for mounting procedure. Magnitude of externally applied torque 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: Bearingslbf 1 1 1 2 1 2 1 1 2 2 3 3 2 lbf 1 1 1 1 1 1 1 2 1 rpm 13 11 11 11 11 10 10 10 8 8 8 8 11 11 7 7 7 7 7 7 9 BEARING MOUNTINGInch Mounting X End Thickness S Shaft Raceway Diameter inchesmax.

Where extremely close control of radial clearance is required for bearings of nominal inch dimensions, extraprecision full complement bearings are available. Inch-metric conversions given are for the convenience of the user.

If the operating temperature must be outside of the above range or if the seals are exposed to unusual fluids please consult the Torrington Engineering Department. The mounted clutch and cwlowe assemblies engages when the housing is rotated relative to the shaft in the direction of the arrow marking LOCK stamped on the cup.

Example 1 Find the ring gauge and plug gauge dimensions for a BH bearing.

Never hammer the bearing into its housing even in conjunction with the proper assembly mandrel. The housing and the clutch are thus free to overrun in one direction, or the shaft is free to overrun in the other direction.
