The most aggressive V-belt ever made for shock-loaded applications.  Available in both PowerBand® belts and Singles, Predator belts have the highest power density of any V belt, and stretch dramatically less than standard cross sections.  Predator belts are ideal for use in the following industries:  Wood Products - timber, logging, pulp and paper, lumber and plywood  Mining  Rock Crushing/Quarry Operations - crushers, shaker screens, conveyors  Oil Field

Ideal for use on problem drive applications requiring high-impact strength and load-carrying power, including: crushers, de-barkers, hogs, grinders, wood hogs, pallet grinders, shredders, tub grinders and car shredders.

Predator Single Belt- when PowerBands aren't an option, Predator Singles are the best problem solver available. These belts are specially designed for use on metric multi-groove sheaves, deep groove sheaves and drives with limited room for "take up". They can also be an "A" section solution for multi-groove A/B sheaves.

Case Studies Carter Holt Harvey Chipper Drive
Four people were required to work six hours every three months in order to maintain a chipper drive running eight SPB 4750 belts. Downtime was costing the company about $7,000 each year with another $2,000 in belt costs annually. By switching to Predator Singles, the company was able to eliminate three belts. Not only are the belts expected to last longer than three months, but it is also anticipated that replacements will not be needed until the 12-month life mark

Green Triangle Forest Products Hogger Drive A hogger drive running five 5V 850 belts was burning through them every few months. When the belts failed, there was 1-2 hours of downtime to replace and re-tension the drive. After running KEVLAR® reinforced 5VP cross section Predator Singles belts on this application for 20 weeks, there was no noticeable wear.

Carter Holt Harvey Band Saw Drive
Significant improvement has been made on a band saw drive using Predator Singles. Even though the pulleys weren’t replaced, the new Predator Singles exceeded the prior four-month life expectancy with no noticeable signs of wear. For every set of belts that they do not need to replace, the company saves $2,000.

Two more advantages of the truncated are:  The belt does not bottom in the sheave The belt can better tolerate debris in the sheave groove. They are extremely smooth running and highly resistant to oil, heat and other adverse conditions.  Specially designed to replace original equipment belts on extra heavy applications such as machine tools, compressors, pumping equipment and other industrial equipment requiring V-ribbed belts.

Exclusive Gates truncated belt design offers up to 80% higher horsepower capacity than Rubber Manufacturer’s Association standards. 
Increased flexibility and reduced heat buildup permit extra high speeds on smaller diameter sheaves. 
Highly resistant to oil, heat and other adverse conditions. 
Less sensitive to debris in sheave groove. 
Meets or exceeds Rubber Manufacturer’s Association standards for static conductivity.
Energy efficient.
Runs cooler than conventional belts. 
High power density. 

Gates Micro-V® Belt Offers Higher Horsepower, Flexibility  Gates Micro-V® belt features an exclusive truncated rib profile that makes it more flexible than a conventional V-ribbed belt, especially on extra-high speed, small-diameter sheave drives.  Also, the shortened rib profile keeps the multi-ribbed belt from bottoming out in sheaves, helps it tolerate debris in sheave grooves, and reduces heat build-up.  The belt is ideally suited for most multi-shaft, serpentine, backside idler and V-flat drives. Usages range from pumps to precision-center lathes to high-speed machine tools.  Gates Micro-V® belt is available in three cross-sections: J, L and M. All three have a smooth-running construction, strong, low-stretch polyester tensile reinforcement, and static-dissipating undercords. They are available in standard rib configurations and sizes, with lengths from 18 inches to 361 inches depending on the cross-section. Special sizes and constructions are available on request.

Micro-V Kit for Belt Jump Off When an “Unfixable” becomes “Fixable” Once in awhile a design comes along that can test your wits. Take the Chrysler 3.0L engine found on 1996 - 2000 Voyager, Grand Voyage, Caravan and Grand Caravan mini vans. The serpentine belt can come off the drive when the vehicle is driven into a deep puddle of water or through a snow bank. And when the belt comes off , your customer can be left stranded. Solutions range from installation of a “snow shield” or adjustment of the front engine mounts to changing the belt, tensioner and idler. Too often the problem persists leading to come-backs and damage to the technician’s reputation and customer good-will. A better solution has been developed by Gates engineers. The Micro-V System Solution Kit includes a double sided Micro-V belt, a grooved idler pulley and matching tensioner which includes a grooved pulley. Each of the components are designed to work precisiely with other parts in the system and offer a true solution. The pulley grooves and belt ribs of Gates System Solution Kit lock together making it virtually impossible for the belt to jump off the drive. Even misalignment problems can be solved. The “unfixable” now becomes “fi xable” thanks to Gates.

Gates Polyflex® JB® Polyurethane V-Belts

Gates PolyFlex JB High-Modulus Polyurethane V-belts for stability and tension.

With a combination high power and precision, Gates Polyflex® JB V-belts are the industry’s top choice for compact, highspeed drive applications.

Gates Polyflex® JB® V-belts are precision products. For maximum efficiency and service life, they must be applied, aligned, tensioned and maintained accordingly .

In general, designers need to pay special attention to adequate bracketry and support. Protective precautions must be taken in hostile environments where the belts could be contaminated by oil, debris or foreign material.

The line of V-belts, readily available from Gates U.S. distributors, encompasses nearly 400 part numbers. Two cross sections are available: eight narrow sizes from XPZ to XPC, and three classical sizes of 10X, 13X and 17X. Standard lengths are from 530 to 3,000 mm.

All Metric Power belts feature Gates V80® matching system. This means each V80 belt is manufactured within a finite length tolerance so that any V80 belt will match and perform with any other V80 belt of the same size and type.

Gates Metric Power belts have several construction features to help reduce equipment maintenance and down time. These include molded notches to reduce thermal and bending stresses; straight sidewalls for uniform wedging action; and specially treated tensile cords that resist flexing forces, fatigue and shock loads.

Gates Power Cable®
Previously recommended by Gates for the toughest shock load applications, Power Cable belts have recently been replaced by Predator® Singles 

Used on drives with little or no take-up, or as an emergency belt replacement.

Belting is sold on reels in standard V-Belt cross sections. Ends are spliced with fasteners that require special assembly tools. Always use the correct fasteners with the correct belt type and cross section.

Nu-T-Link*, a new, high performance spliced belt, is also available for use as emergency belting, and for drives where conditions are detrimental to rubber belts.
