This Standard establishes acceptable manufacturing tolerances, methods of measuring, and proper application for drives using V-belts or V-ribbed belts. They may be used individually or in matched sets. This Standard is unique to agricultural belt drives and should...
This Standard provides specifications for the ring-shaped synchronous endless trapezoidal profile belts (hereafter referred to as belts) and machined pulleys (hereafter referred to as pulleys), among other pulleys. It is not applicable to automotive belts and pulleys. It is...
This International Standard specifies the principal dimensions of grooved pulleys for classical V-belts (sections Y, Z, A, B, C, D and E) and narrow V-belts (sections SPZ, SPA, SPB and SPC) specified in the terminology system based on datum width. It is important that narrow...
Introduction Note: Nothing in this standard supercedes applicable laws and regulations. Note: In the event of conflict between the English and domestic language, the English language shall take precedence. Purpose. This standard covers supplier requirements for engine accessory drive...
Single and double V-belts, matched belts, V-grooved pulleys, pulleys with movable flanges for variable speed drives. Dimensions, finish, balancing. New methods for pitch length designation and power design calculation of double V-belts. Recommendations for ¼-turn...
Requirements for synchronous pulleys and endless belts (of pitch code 2A). Describes a flex fatigue test and gives guidance on system design.
This specification covers general requirements for standard and heavy duty endless V-type engine accessory drive belts of various lengths and belt widths. The belts are either plain or notched or cogged base.
