See the previous discussion on internal clearances and fits for further details on inner raceway diameter choice. These are tabulated on pages to of the drawn cup section.
Oil lubrication is absolutely necessary for high speed operations. Published on Apr View 83 Download calowf. When ordering, please specify if lubrication groove and hole are desired.
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 general information regarding lubrication of drawn cup bearings refer to page E 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 design provides maximum cage strength consistent with the long life requirements. Our philosophy of the work is working on the assumption, that the most important thing in contemporary sale is solving problems of the customer. They are applying worldwide in all branches of industry. Sealed drawn cup bearings are intended to retain grease or nonpressurized oil within a bearing while also preventing contaminants entering the raceway area.

The mounted clutch engages when the housing is rotated relative to the shaft in the direction of the arrow marking LOCK stamped on the cup. Description of Tabular Data.
Never hammer the bearing into its housing even in conjunction with the proper assembly mandrel. Hardened inner rings may be used where it is impossible to use the shaft as the inner raceway.
When applying the clutch-only unit, separate bearings on each side of the clutch are required to position the shaft concentrically with the housing and to carry the radial loads during overrun.
The calode deviation from true circular form of the raceway should not exceed. Axial motion between shaft and clutch rollers prevents lockup. The seal lip design achieves a light and constant contact with the shaft throughout the range of mounting bearing clearances thereby ensuring positive sealing and low frictional drag.
The basic types of clutches and clutch and bearing assemblies are listed below: See tables of bearing dimensions for the required raceway diameter. The housing should be of high strength material.

Through bored housings are always preferred. Either case hardening or through hardening grades of good bearing quality steel are satisfactory caloww raceways.

Sealed DC bearings are shown on pages and extraprecision Calode bearings are shown on pages The correct method for inspecting the bearing size is to: Continued on the next page. Load ratings are based on a minimum raceway gwihty of 58 HRC or equivalent. The housing bore should be round within one-half of the diameter tolerance. Consequently, the tabular data on pages to can be used in bearing size selection.
Przestrzenie metryczne, cigi liczbowe Documents. The larger cross section is indicated by the prefix code letter H. Mary Mc Verry, Eng. If clutch is straddled by needle roller bearings, press units into position in proper sequence and preferably leave a small clearance between units.

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. Most sizes of inch bearings are available with either a full complement of rollers or caged rollers.
City of Torrington – National Center on Grease lubrication or improper fitup housing bore and shaft diameter may increase backlash. Outer Ring Rotation, Oscillating Motion.
For raceways greater than 1. When using adhesives, care must caloae taken to keep the adhesive out of the clutches and bearings. Since the bearing designation prefix does not include the letter SF or HK, this bearing is of nominal inch dimensions.
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. Consultation with the Engineering Sales Office is recommended when overrunning speeds are high.
Amount calwoe RecessChamferMake sure that the housing bore is chamfered to permit easy introduction of the clutch and bearing or the clutch unit.
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. These are designated by ordering a GB bearing.
