TFS20 Textile Machine Sprag Freewheel One Way Clutch Bearing ASNU20
One Way Clutch Bearing Tfs20 - One Way Sprag Clutch Bearing
Type ASNU is a roller type freewheel nonbearing supported. Bearings are required to support axial and radial loads. Lubrication and sealing must
also be provided by the installation. Nominal outer diameter is the same as a series 63...Ball bearing
A typical arrangement is to install this type alongside a bearing within the same location tolerances, as shown on the following page. The inner
race is keyed to the shaft.
The outer race has positive n6 tolerance, to give a press fit in a H7 housing. Additional side notches in the outer race provide for positive torque
transmission.
If the housing is to K6 tolerance, use of the notches is not necessary, but the housing must be strong enough to not expand after assembly. This
design can accept an axial misalignment of inner and uter race of ± S/2.
