The J Type flanges in sizes 3J and 4J are made from die cast of high strength zinc alloy (tensile strength of 41,000 psi) and are furnished bore-to-size.
Size 5J is provided in either zinc alloy or cast iron depending on the bore size.
Size 6J is made from cast iron.
J flanges are compatible with EPDM or Neoprene sleeves.
Each flange has a keyway and two set screws (one set screw over the key and one at 90° to the keyway).
The J Type coupling consists of two flanges and one sleeve.
Spacing between shafts should be greater than 1/8 inch and less than OAL minus the sum of the two bore dimensions.
