SPC (22) pre-drilled disc
Description
The basic drilled pulley with a centering hole in the middle, possibly a centering marking. Each disc can be drilled and customized within the range specified by the manufacturer (in field Size3). The disadvantage is that it requires machining, i.e. we will need cutting to make the hole and latch track. In the Size3 field, we indicated the hole range to which the pulley can be safely drilled, according to the manufacturer. SPC pulleys can be used for belts marked C. (22mm wide profile belts: C, SPC, XPC)
The dials are numbered: SPC nominal diameter / number of tracks and an E indicating that the disc is pre-drilled... The maximum diameter (Do) of pulleys marked SPC shall be at least 9,6 mm larger than the nominal diameter (measured at the location of the force carrier). SPC discs shall have a minimum track depth of not less than 19 mm calculated from the nominal diameter (Dp) measured at the point of the support fibre. In the case of Sati**** branded products, the delivered product is not always Sati branded, but in some cases Optibelt, Concar or other branded products, but completely identical in design to Sati.
