Safety critical note

Same rule as the smaller 22-30 size - cylindrical groove (Nut) between square journal and shaft body is mandatory, and VT1 driver disc MUST be fitted whenever the bearing sits on a web-guide-regulator slider.

Commonly combined with Bahnlaufregler via slider-mounted configuration - VT1 driver disc mandatory.
