1120-8M-20 HTB Timing Belt

The standard trapezoidal tooth timing belt design performs poorly in high-torque applications and high-power drives at lower speeds.  To overcome this disadvantage, the High-Torque Belt (HTB®) was developed using a more efficient tooth profile.

Among the advantages are:

• Higher torque transmission at low speeds
• High power transmission over a wide speed range
• Improved meshing to reduce tooth jump
• Higher resistance to tooth shear
• Less tooth wear due to friction

Non-standard lengths in 5mm, 8mm and 14mm pitch are also available, as are belts with 3mm pitch. 

3M – 3mm HTB® Synchronous Belts

Many lengths are in stock and can be cut to the desired width.  Additional 3mm pitch HTB® Belt sizes are available on a made-to-order basis.  Please check with Jason/Megadyne for availability.  HTB® Synchronous Belts are specified by belt pitch length, tooth pitch and belt width in millimeters.  Example: 720-8M-30

Features & Benefits

• Fiberglass Tensile Cord– High dimensional stability and maximum flexibility
• Chloroprene Belt Body– Oil, heat and ozone resistance; high tooth shear resistance
• Nylon Tooth Cover– Durability and wear resistance, increased power capacity

Construction
