TR (Rear Mount) Type Flanges for use with Taper-Lock® Bushings Timken 68514462274

Описание

TR flanges are similar to the TF style, but allow for the Taper Lock Bushing to be mounted and removed from the reverse or serration side of the flange The limited torque ratings of the Taper Lock Bushings allow TR flanges to only be used with EPDM or Neoprene sleeves Different bushing sizes are used, so they have different maximum bores than the TF flanges Sizes 6 through 16 are available Specifications Description 8TR-FLNG-TAPER STD UNC THREAD Coupling Size 8TR Type Coupling Flange Material Cast Iron Weight 17.00 lb Color Gray Bore Type Bored to Accept 1215/1210 Taper Lock Bushing Mount Type Rear Bushing Required 1215/1210 Coupling Type S-Flex UNC Flange UPC Number 62274 Dimensional Data Keyway Size (W x D) No Keyway Hub Diameter 3.250 in Dimension L 1.940 in Outside Diameter 5.450 in Overall Length 5.00 in Max.

In the U.S.A. the UNC type is predominant for both inch and metric bores. Outside of the U.S.A. it is most common to see B.S.W., especially on metric bores.
