Keyless Timing Pulleys - T10 - MechaLock Standard Type Incorporated (with Centering Function)
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.

*3 For the combination of nominal width and MechaLock inner diameter shown in Table 2, the MechaLock mounting holes are not stepped holes, but are through holes of the MechaLock outer diameter. ([!] Shape E only)
[ ! ] Surface treatment may not be applied to the shaft bores.
[ ! ] Machined flange for 34, 50 and 60 toothed pulleys.
[ ! ] For orders with no flange, please specify the alteration NFC.
[ ! ] Unless otherwise specified except for teeth and F dimensions, the dimension tolerance conforms to JIS B 0405 Class m.
