Common Itoh Roller Diameters

• 1.50” (38.0mm)
• 1.68” (42.7mm)
• 1.91” (48.6mm)
• 2.25” (57.0mm)
• 2.38” (60.5mm)
• 2.50” (63.5mm)
• 3.00” (76.3mm)

(Convert English units to Metric units, 1 inch=25.4 mm)

6 – Between frame dimension: What is your between frame dimension (BF)?

• In determining the correct length of the Power Moller required, you should first obtain the between the frame width of the conveyor you will be mounting the Power Moller in.
  • All dimensions need to be converted to millimeters.
• Take the between the frame width and subtract 15mm to account for bearing end caps and clearances to achieve proper tube length.
  • Subtract 21mm when using the “JQ” type shafts.
  • For the PM635FS the deduction will be 20mm
  • Please reference catalog pages for proper deduct measurements for specific roller options.   

7 – Options: Does the application call for any special options?

• Lagging (Natural Rubber, NBR, Neoprene, Urethane)
• Dust-proof (DP)
• Waterproof (WA)
• Brake (BR)
• Grooves (P2- standard @ 50/32 mm)
• KF – Brackets not ordered with roller
• Etc.
• Please reference catalog pages for options for each roller model. Options do vary by model. 

Important Formulas:
Tangential Force (TF)

•  Tangential force is the force in lbs. that is needed to move the item on the conveyor.
  • The force tangent to the roller’s surface.
  • Tangential force F can be found by the following formula:

Formula 1
TF = µ X W
TF = Required tangential force
W= Weight of article to be transferred
µ = Coefficient of rolling friction in accordance with the material composition
of the bottom of the article to be transferred. (See Table I)

• To determine the number of POWER MOLLER units required for transfer, compare required tangential force (F) and the tangential force of one POWER MOLLER unit (f)

Formula 2
Number of POWER MOLLERS required = F/f

The above values are based on industry standards of products with a smooth, uniform bottom surface in contact with the roller.
