Product Features

Feature 1: MISUMI flat belt pulleys are suitable for transmission and conveying designs
Feature 2: MISUMI flat belt pulleys come in standard straight cylindrical, flanged, arc-shaped to effectively prevent belt deviation, and ribbed keyway types to further prevent deviation, meeting various design requirements.
Feature 3: MISUMI flat belt pulleys are available in polyurethane products, suitable for various application environments.
Feature 4: MISUMI flat belt pulleys have shaft hole dimensions with H7 tolerance, which is the industry standard.

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.
Please refer to

Surface Treatment and Rust Prevention Methods
(2) The tolerance accuracy of Dimension T of the belt groove is ±0.2 mm. Please select the pulley model after confirming the width tolerance of the flat belt.
(3) For hole specifications round hole + tap or keyway + tap, the fixing screws are not included.

Example of Use
