Which pulleys are used for classic belt types 10, 13, 17 and 22?
Standard V-belt pulleys SPZ, SPA, SPB, and SPC are used for classic V-belts 10, 13, 17 and 22. These pulleys can actually be used for all kinds of classic V-belts, narrow V-belts and raw-edged belts with inner cogs.
Sole exceptions are multiple V-belt types HA, HB, HC, 3VJ, 5VJ, which have a different pitch than SPZ, SPA, SPB and SPC belt types. These require the use of a special V-belt pulley.
It is also necessary to produce special custom-ordered pulleys for belt types 8, 20, 25, 32, 40 and 50.
