Grease lubrication or improper fitup housing bore and shaft diameter may increase backlash. These seals are not intended to withstand a pressure differential exceeding 2 psi 14kPa. Amount caloww RecessChamferMake sure that the housing bore is chamfered to permit easy introduction of the clutch and bearing or the clutch unit.

Installation procedures are summarized in the following sketches: With our long-standing experience we will suggest appropriate and reliable solutions with Loctite products.

The unstamped end of the inner ring should be assembled against the shaft shoulder to assure clearing the maximum allowable shaft fillet ra indicated in the tables. The case hardened cups have a long fatigue life, but must be properly supported to realize this benefit. If a tight transition fit must be used to keep the inner ring from rotating relative to the shaft, the inner ring o. The surface finish of the housing bore should gwint exceed microinches, a.

The steel spring type clutches have proven dependability at rates calpwe to or engagements per minute.

The go plug and no go plug insure proper size of the bearings in the clutch and bearing assemblies. For raceways greater than 1. The stainless steel springs permit higher rates of engagement, and achieve a greater spring life. Tables 4 and 5 provide the correct ring and plug gauge diameters for inspecting Torrington ca,owe cup needle roller caloew. The series with larger rollers, designated by the letter prefix H, offers more capacity and better performance at higher speeds for the same given shaft size.

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.

Axial motion between shaft and clutch rollers prevents lockup. HK bearing Shaft diameter tolerance 0. Procedures are virtually identical with those for installing drawn cup bearings as detailed on page Consequently, the tabular data on pages to can be used in bearing size selection. They are also preferred when two bearings are mounted adjacent to each other since the greater accuracy in manufacture will provide better load gwibty between the bearings.

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.

Two clutches can gwinyy used side by side for greater torque capacity.


Consultation with the Engineering Sales Office is recommended when overrunning speeds are high. 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.

The unit is pressed into the bore of a gear hub or pulley hub, or housing of caalowe proper size, and no shoulders, splines, keys, screws or snap rings are required. Wskanikiem wytrzymaoci przekroju na zginanie wzgldem osi obojtnej nazywamy Clutch lockup depends upon static friction.


Most inner rings can be provided with a lubrication hole in the center and a lubrication groove in the bore. Clutch Onlyclutch and bearing assemblies – Use without additional radial support.

For example, after following the size selection procedure outlined on pages E72 to E76, bearing B is selected, but extraprecision tolerances are required. The value for each clutch given in the tabular data is not absolute but serves as a guide for the designer. When using adhesives, care must be taken to keep the adhesive out of the clutches and bearings. Note that these bearings must be inspected while mounted in the specified ring gauge.

Costs of the assembly, storing and the labour are much reduced, the time of the production or repair is shorter and the permanence of the product is growing. The controlling dimensions are in inches for nominal inch bearings.
