Martin 13L050 DF-1 Style, 3/8" Pitch, Light, 1/2" Wide Belts, 0.375" Bore Timing Pulley

Key features

• Grooved design for applications requiring synchronous rotation
• High carbon steel for tensile strength and hardness
• Light (L) pitch profile for use with same-pitch trapezoidal tooth belts
• Stock bore, does not require use of a bushing
• Double flange to resist belt side thrust and maintain belt contact

This Martin DF-1 type timing pulley is suitable for use with 1/2" and 3/4" wide trapezoidal tooth belts in power transmission applications that require synchronous rotation. It is made of high carbon steel for tensile strength and hardness and has a Light (L) pitch profile. This pulley has a plain bore and mounts to a drive shaft using set screws. Double flanges on the pulley resist side thrust and maintain belt contact. Timing pulleys are a type of drive pulley and are used in a wide range of mechanical and electronic drives, including automotive and printing industries.Pulley drive systems consist of two or more pulleys that connect with a belt to transmit mechanical power across greater distances than systems that use gears. Pulleys (sheaves) are available in different types: V-belt, timing, round, or flat. Pulleys must match the belts that connect them (timing pulleys with trapezoidal grooves require a belt with trapezoidal teeth) and engage either on the sides of the pulley flange (classical V-belts, narrow V-belts, or round belts), on the flat outer diameter of the pulley (flat belts), or in pulley grooves that match belt teeth (timing belts, synchronous belts, or curvilinear
