Product Description
This is an economy item, The price is cheaper than the MISUMI standard product.
Product Overview
Usually, flat-belt pulleys and flat belts are widely used in mechanisms design for transmitting rotational power generated by motors.
Driving and transmission are realized through the friction fit between flat-belt pulleys and flat belts.

Usage Method
■ Intend Use for Flat-belt Pulleys
| Usage Method Example Drawing | Use Instructions for Flat-belt Pulleys |
![]() | The workpiece can be transmitted by the combined use of pulleys for flat belts, idlers for flat belts, and flat belts. The flat-belt idlers can also play the role of tensioning the belt. |
Precautions
(1) If there are requirements for rust prevention, give priority to products with surface treatment of electroless nickel plating or those made of SUS304.
