Small Drive Belts

Superior's small drive belts have been proven in many industries and applications, including:

• light conveying (both weight carrying and drive belts)
• plastics converting industry
• textile industry
• paper and poly films industries in wicketing machinery
• pharmaceutical industry
• bottling industry

and any application requiring extremely durable round belts. That's because Superior's versatile design features offer many outstanding advantages.

Maximum Flexibility
Because Superior manufactures to your specifications, our small drive belts are practical for use even in unusual configurations, including:

• variable and multiple speeds
• multiple planes
• serpentine drives
• reverse bends
• 90 degree twists
• speeds up to 250,000 RPM

Improved Efficiency
Superior's long life, outstanding quality and proven performance can improve your operation's productivity and efficiency by eliminating:

• belt take-up assemblies and devices
• belt noise
• joint bump
• vibration
• field maintenance
• lubrication of idler pulleys and parts
• springs, cams, buts, slotted holes & stampings

Reduced Costs
Because Superior small drive belts provide permanent belt tension at a single center set-up, you save money by reducing:

• production and maintenance costs
• handling
• parts inventory requirements

Endless Belts
The flexibility, traction and durability of Superior endless belts have been proven in a range of industries.  Tests prove that Superior three-ply endless belts last several times longer than standard O-ring drive belts, in any application and in any size, because the construction process eliminates wear at the point of connection.  Multi-ply construction and the addition of special coatings produce belts that resist nicks and cuts, unlike solid single-strand rubber and polyurethane belts.

Hook-Clip Belts
Available in the same sizes as endless belts, Superior's hook-clip belts can be used in many diverse applications.  These belts can quickly and easily be fitted around the drive radius and joined using the pre-installed hook, greatly reducing downtime.

Variable Elasticity
Superior elastic belts can be made with varying degrees of stretch to meet your specifications.  Because elastic belts eliminate vibration and belt noise, they are ideal in fractional horsepower applications where quiet, dependable operation is required.
 

• Pulley root diameter should be at least six times belt cross-section diameter.
• Half round pulleys are recommended for Superior's belts, however, in many applications they are being used in V-groove pulleys.
• Surface speed loss should be calculated at 13% and belt efficiency at 80%.

All applications that appear to be borderline should be sent to Superior's engineering department.

Superior elastic belts eliminate vibration - joint bump and the need for belt take-up components.

The flexibility, traction and durability of Superior elastic belts have been proven in textile machinery drives, plastic bag manufacturing, conveyers and many other applications requiring extremely durable round belts.

The belts, available in treated or untreated elastic types, are made to your specifications in sizes from 0.025 to 0.50 diameter and from 3 inches to 20 feet in circumferences.

Superior elastic belts can be made with elasticity, or stretch, from 20% to 150%.  Superior's designs are also furnished for diverse applications requiring a clip-type drive belt.

Superior developed the only valid patent on endless twisted belts - a three-ply belt, which lasts several times longer than O-ring type belts. A long-time leader in the textile industry, Superior has seen more than half the textile mills in the nation standardized on these belts and now the belts are available for all industry.

Superior belts are ideal for fixed center drives where belt stretch causes a problem.  The elastic feature also allows this belt to drive eccentric pulleys, and pulley centers can be changed without changing the belt.
