The correct method for inspecting the bearing size is to: Since the bearing designation prefix does not include the letter SF or HK, this bearing is of nominal inch dimensions. The value for each clutch given in the tabular data is not absolute but serves as a guide for the designer.
See pages E for discussion of shaft and housing design. Gwihty 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.
It is advisable to utilize a positive stop on the press tool to locate the bearing properly in the housing. For inspection purposes, see tolerance tables on page Extraprecision bearings are suitable for those applications requiring close control of radial play and eccentricity. Inner rings for valowe cup bearings are designed to be a loose transition fit on the shaft and should be clamped against a shoulder. Separate bearings position the shaft and housing concentrically and carry the radial load during overrun.

Manufacturing tolerance for bearing. Caged Bearing Construction, Sealed Bearings.
The housing and the clutch are thus free to overrun in one direction, or the shaft is free to overrun in the other direction. The controlling dimensions are in inches for nominal inch bearings. The rollers, assisted by the leaf type springs, become wedged between the locking ramps and the shaft to transmit torque between the two members. Przestrzenie metryczne, cigi liczbowe Documents.
The go gauge size is the minimum diameter inside the needle rollers. In production operations using closer tolerances on shaft and housing, they will assemble with consistently lower radial internal clearances than can be expected with the precision series bearings. 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.
When ordering, please specify if lubrication groove and hole are desired. The case hardened cups have a long fatigue life, but must be properly supported to realize this benefit.
Applications involving loads approaching this rating or the tabulated working load, whichever is the smaller, should be referred to your Engineering Sales Office before a final selection is made.
When using adhesives, care must be taken to keep the adhesive out of the clutches and bearings.
Never hammer the bearing into its housing even in conjunction with the proper assembly mandrel. For those applications where oil is not practical, clutches claowe packed with a soft grease containing mineral oil.

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. Bearings of nominal metric dimensions should follow ISO R7 and f6 tolerance practices.
Torrington also has available bearings with other cage designs. Nominal gwinyy with rounded conversions are shown below. Transition from the overrun to locked operation normally occurs with minimal lost motion backlash.

We are a typically engineering company which is preferring technical rather than only purely commercial aspects of the marketing process of Loctite products.
The resulting total radial internal clearance within the installed GB extraprecision drawn cup needle roller bearing will lie in the range from 0. The radial deviation from true circular form of the raceway should not exceed. Load ratings are based on a minimum raceway hardness of 58 HRC or equivalent. Make sure that the unit is oriented properly before pressing it into its housing.
The stainless steel springs permit higher rates of engagement, and achieve a greater spring life. Published on Apr View 83 Download 1. City of Torrington – National Center on
