Flat Belts Pulleys Width 6 - 32

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.

Type			Material	Surface Treatment
Flanged	Crowned	Press-Fit Urethane Type		Liner
E-HBPG	E-HBPCG	-	General structural steel or carbon steel	Ferroferric Oxide Protective Film
E-HBPM	E-HBPCM			Electroless Nickel Plating
E-HBPA	E-HBPCA		Aluminum Alloy	Clear Anodized
E-HBPS	E-HBPCS		Austenitic stainless steel	-
-	-	E-HBPUS		Urethane Shore A70

If there are requirements for rust prevention, give priority to products with surface treatment of electroless nickel plating or those made of austenitic stainless steel.

Feature 1: MISUMI pulleys for flat belts are suitable for transmission and conveyance designs.
Feature 2: MISUMI pulleys for flat belts are available in ordinary straight type, flanged type, crowned type effectively restraining running deviation, and crosspiece groove straight type effectively preventing running deviation, and are suitable for a wide range of design requirements.
Feature 3: With urethane products available, MISUMI pulleys for flat belts are suitable for a variety of applications.
Feature 4: The shaft hole size of MISUMI pulleys for flat belts has a tolerance of H8, which meets the industry standard.

■ 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 idlers for flat belts can also play the role of tensioning the belt.

①If there are requirements for rust prevention, give priority to products with surface treatment of electroless nickel plating or those made of austenitic stainless steel.
 Please refer tosurface treatment and rust prevention methods
② The tolerance accuracy of Dimension T of the belt groove is 0.2mm. Please select the pulley model after confirming the width tolerance of the flat belt.
③ For hole specifications round hole + threaded hole or keyway + threaded hole, the fixing screws are not included.
