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.
Stock 5 mm, 8 mm and 14 mm pitch HTB timing belts are listed below. Non-standard lengths in these pitches are also available, as are belts with 3 mm pitch.
HTB timing belts are specified by belt pitch length, tooth profile, and tooth pitch code and belt width in millimeters.
3 mm HTB Timing Belts Many sizes are in stock. Other 3 mm Pitch HTB Belts are available on a made to order basis. Please check with ...
Dual HTB belts are often used in reversing or serpentine applications.
Special widths are available: use price for next width stock belt. Materials are same as standard belts except that teeth on one side are ground from fiber reinforced neoprene stock. Power takeoff from ground side is limited to 50% of total belt rating. Teeth with nylon facing should always be on driver pulley.
Any width available from stock, consult Jason for pricing.
Double sided belts afford power transmission from either side of the belt and are often used in reversing and serpentine applications.
They are specified the same way as timing belts except with a "D" prefix. For example: D240H100. Special widths are cut to order from our sleeve stock for fast delivery.
Double sided timing belts are produced using the same materials as single sided belts, except that the backside is ground from a fiber reinforced special rubber compound. There is no nylon facing on the backside. Power take off on the backside is limited to 50% of the total catalog rating.
Total belt rating is the same as for single sided belts.
(50) Specially suitable for linear drives, accurate positioning, metering and reversing applications. High load capacity, no maintenance cost and very low noise level make these belts a perfect alternative to chain or cable reverse drives.
Double Sided - until now, chain was the only design option for drives requiring long spans and the capability to drive from either side. The advantages of Open-End synchronous belts (no lubrication, no re-tensioning, high-speed capabilities) makes such drives more versatile than ever.
Jason/Megadyne Open-End synchronous belting is specified by an "L" for long length, the belt pitch code and the width code (i.e. L8M-20). Length is specified in feet. Double Sided Open-End is specified "DL" ...
