Description

21PK AUTOMOTIVE MULTI-V BELT RANGE

21PK Multi-V Belts in 13 Listed Sizes

SUMATE supplies 21PK multi-V belts for automotive and mobile-equipment accessory-drive systems. Each belt uses the PK rib profile and has twenty-one longitudinal ribs. Available codes in this range extend from 21PK582 to 21PK2523, covering passenger-vehicle applications as well as belt-drive layouts used in commercial vehicles, construction machinery, and agricultural machinery.

In a code such as 21PK1000, “21” identifies the number of ribs, “PK” identifies the rib profile, and the final number indicates the nominal reference length in millimetres. The complete code, OE number, pulley layout, and application information should be checked before purchase.
