Caution
- Regarding RoHS compliance: The products are RoHS non-compliant only when alteration BMC is selected. The products are RoHS-compliant when BMC is not selected. As some parts used in the alteration are RoHS non-compliant, the RoHS notation on this page has been changed to non-compliant. "Non-compliant" is also indicated in the certificate due to information on the left.
- Please note that the swaged flange options, NFC, RFC, and LFC, are not reflected in the CAD data.

[ ! ] Surface treatment may not be applied to the shaft bores.
[!] Two types of bushings are available: standard type (ST bushings) and short type (SH bushings).
[ ! ] Electroless nickel plated bushing (alterations BMC, BMR) decreases maximum allowable torque and allowable thrust load by 20 to 30%.
[ ! ] Unless otherwise specified except for teeth and F dimensions, the dimension tolerance conforms to JIS B 0405 Class m.
