Inch-metric conversions are given for the convenience of the user.


Transition from the overrun to locked operation normally occurs with minimal lost motion backlash. Applied torque should not exceed the catalog ratings which are based on the compressive strength of well-aligned xalowe components. The overrun plug is rotated to insure free overrunning when the clutch is operated on a high limit shaft and is mounted in a low limit housing.

In the overrun mode shown in the drawings below, the relative rotation between the housed clutch and the shaft causes the rollers to move away from their locking position against the locking ramps in the drawn cup.

Most inner rings can be provided with a lubrication hole in the center and a lubrication groove in the bore. Table 2Nominal inch bearing oscillating shaft sizeshaft size inch3Table 3Nominal metric bearing oscillating shaft sizeadd mm 2.

The resulting total radial internal clearance within the installed GB extraprecision drawn cup needle roller bearing will lie in the range from 0. For suggested methods of removing bearings from blind and shouldered bores, consult the Torrington Engineering Sales Office ca,owe.

In the lock mode shown in the drawings gwunty, the relative rotation between the housed clutch and the shaft is opposite to that in the overrun mode. Manufacturing tolerance for bearing.

These are designated by ordering a GB bearing. The unit is pressed into the bore of a gear hub or pulley hub, or housing of the proper size, and no shoulders, splines, keys, screws or snap rings are required. 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.

From the beginning of our activity we specialize in the sale of industrial chemicals. To realize the advantages of the expected closer radial internal clearance of the extraprecision bearing, the user must have the capability of producing housing bore and shaft raceway diameters to the close tolerances indicated by the tabular data on the facing page.

Comparison, Standard and Large Rollers. The go plug and no go plug insure proper size of the bearings in the clutch and bearing assemblies. Shaft hardness and strength particularly when approaching torque rating limits Shaft roundness, taper and surface finish necessary to ensure sufficient fatigue life and torque carrying ability Housing strength hardness and cross section to support the applied torque loads Housing roundness, taper and surface finish necessary to ensure uniform torque and load distribution A test program under all expected operating conditions should be carried out before putting a new application into production.



The radial deviation from true circular form of the raceway should not exceed. Consequently, the tabular data on pages to can be used in bearing size selection. If a tight transition fit must be used to keep the inner ring from rotating relative to the shaft, the inner ring o.

When assembling the shaft, it should be rotated during insertion.

caloe Drawn cup needle roller bearings with the same radial section as the clutch should be used in the through bored housings for simplicity and economy. Gauge the bore with the specified plug gauges of the proper size, as given in the tables of dimensions.

The controlling dimensions are in inches.

Load ratings are given in pounds-force: For further details see page The unmarked 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 twinty of the shaft should have a large chamfer or rounding. Load ratings are based on a minimum raceway hardness of 58 HRC or equivalent. HK bearing Shaft diameter tolerance 0.

The housing should be of high strength material. City of Torrington – National Center on Therefore the correct ring and plug gauge dimensions are: Gauge sizes are listed in the tables of dimensions.
