Flat Belts Idlers Width 25 - 100

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.

Bearing is pressed fit.
Bearing cannot be removed.
The tolerance accuracy of T is ±0.2mm. Please select the idler model after confirming the width tolerance of the flat belt.

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.

*T=6 is not available for the crowned type.
* 2 For the crowned type with T=16 or D=35 or 40, the dimensions of the bearing are values in ( ).
Refer to the detailed dimensions of the relevant bearing.
MISUMI makes no commitment to the bearing brand.
E-HBGP is only available in specifications marked with *.
The tolerance accuracy of T is ±2mm. Please select the idler model after confirming the width tolerance of the flat belt.

Feature 1: MISUMI idlers for flat belts are suitable for conveying design and also play the role of tensioning the belt.
Feature 2: MISUMI idlers 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 polyacetal products available, MISUMI idlers for flat belts are suitable for a variety of applications.
Feature 4: MISUMI idlers for flat belts use standard class 0 bearings and meet the industry standards.

■ 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.
