Precautions
- *Key grooves and taps are JIS compliant sizes. Please check with your own account to see if they are suitable for your conditions of use. Or contact us for more information.
Processing specifications (tap processing position)
AF type
BF type
- *For the AF type, the tapping angle at the second location is an approximate value (due to machining on the pulley tooth root).
- *If the tapping length is long, a counterbore hole may be machined.
- *For tapped specifications, a set screw is attached to each tapped hole.
Set screw specifications
- Hexagonal socket, recessed tip type, made of steel.
- If the body is plated, a stainless steel set screw is installed.
