Features of MISUMI Timing Belts XL timing pulley
①Well processed teeth→High processing accuracy
②Threaded hole deburred→Longer service life of timing belt
③Evenly press-fitted retainer→Firm retainer, not easy to fall off
④Beautiful tooth shape→Precisely engaged belt, with high concentricity
Usage Method
Usage Method Example DrawingUsage Method of Timing Wheel and Timing Belt
MISUMI Timing Belt Driving Example  timing pulley①Driving (The driven wheel is driven by the driving wheel for transmission)
MISUMI Timing Pulley Linear Driving Example  timing pulley②Linear driving (Reciprocating motion is carried out through the free-end toothed timing belt.)
Usage Method Example DrawingUsage Method of Timing Wheel and Timing Belt
MISUMI Timing Pulley Conveyance Example  timing pulley③Conveyance (Plates are conveyed by two toothed timing belts)
MISUMI Timing Pulley Traction Transmission Example  timing pulley④Traction transmission (Workpieces are clamped and transmitted by the belt)
Precautions
①For Shaft Bore Specs. P (round hole+threaded hole) or N, the attached set screws are shipped in the same package (may drop in the packaging bag).
②There is no threaded hole for Shaft Bore Specs. H (round hole).
③The surface treatment may not be performed inside the shaft hole.
④For keyway dimensions, refer to Keyway Detailed Dimension Table.
For the N keyway hole, the position relation between keyway and tooth is not fixed.
Example of Use
