Eliminates Slippage
Positive grip of belt teeth with "Timing Pulley" grooves eliminates Slippage, speed variation. There's no initial stretch no elongation to require belt take up because of high modulus tension member.
Less Bearing Load
Since the Positive Drive Belt does not rely on friction. there is no need for high initial tension. Thus, overhung bearing loads are reduced to minimum. Motor bases and idlers are frequently eliminated.
Less Space
Small Timing Pulleys, Short centers, narrow belts, high capacity-all these inherent features can be combined to reduce space requirements. Center distance can de permanently established.
Constant Angular velocity
Speed is transmitted uniformly. There is no chordal rise and fall of pitch line as with roller chain, no belt creep or slippage-thus no chatter or vibration. As an example: higher-quality machined and ground surfaces.
Smoother Running
Because of advanced design. backlash-between the teeth of stock belts and grooves of stock pulleys-is reduced to a negligible minimum. Thus, Positive Drive Belt Drive Belt drives frequently outperform Precision gear drives.
Less Maintenance
Maintenance costs can be reduced because absence of metal-to-metal contact eliminates the need for lubrications systems. oil-retaining devices and their nuisance. cost, weight, possibility of product contamination.
Wide Range of load capabilities
The load capabilities of Positive Drive Belt drives range from subfractional horsepower to 600 hp and up. Their torque loads range from thousands of foot-pounds down to light loads in inch-ounces.

Wide Speed Range
- POSITIVE DRIVE BELT, - CHAIN, - V-BELT, - STOCK GEARS, - FLAT BELT
This the only stock power transmission medium with the extreme speed range of under 100 rpm to over 6,000 rpm. The speed-range graph tells the story. (For safety, rim speeds of cast iron stock pulleys should not exceed 6,000 rpm.)
Less Noise
Throughout the normal speed range of industrial and light-duty drives. the noise level is relatively low-an important consideration in many machine and equipment installations.
Less weight
The horsepower-to-weight ratio is high-an important consideration where weight is a critical factor, such as in aircraft and portable equipment. Timing Pulleys can be made of light metals or nonmetallic materials.
Economical
These drives do not require motor bases, lubrications systems, tensioning devices. thus minimizing original and maintenance costs.
