TF Style Flanges
Model TF flanges are made from the identical high-strength cast iron as the S flanges, but are made to accommodate the international normal Taper Lock bushing for straightforward set up and removal
TF Form flanges make it possible for for mounting the bushing to the front (hub) side of the flange
TF flanges are available in sizes 6 by sixteen and will be used with any style of sleeve as pictured on web page SF-5
TR Style Flanges
TR flanges are comparable on the TF style, but make it possible 
for to the Taper Lock Bushing to become mounted and eliminated from
the reverse or serration side on the flange
The restricted torque ratings on the Taper Lock Bushings permit TR flanges to only be utilized with EPDM or Neoprene sleeves
Various bushing sizes are made use of, so they have different optimum bores compared to the TF flanges
Sizes six by means of sixteen are available
Taper-Lock Bushings
The industry typical taper lock bushing is actually a split design and style making it possible for a compression fit in the flange on the shaft without the need of set screws
The easy design and style tends to make the installation and elimination easy while the 8° taper grips tight and supplies superb concentricity
A Lowered level of inventory is often accomplished on account of the many other electrical power transmission parts that use Taper Lock Bushings such as: sheaves, sprockets, and pulleys
will not offer the Taper-Lock Bushings themselves as they’re broadly available from other manufacturers
