Poly-F Plus is a reliable product from J.K. Fenner for all kinds of industrial applications. Poly-F Plus belts need less maintenance because of the specially designed polyester cord. These are best suited for remote applications which cannot be maintained regularly. These are Anti-static and Oil and heat-resistant, providing better life in all applications.

Continuous research work and efforts in development of V-Belts have been made to introduce the latest type of Spacesaver Wedge Belts. This line of Wedge Belt drives is engineered to utilize in full, all the performance capabilities of modern man-made fibres and synthetic rubbers. Four sections of Wedge Belts SPZ, SPA, SPB & SPC confirm to BS3790

In combination with Fenner Dual Duty Taper Lock? Pulleys machined to close limits from high grade materials, these Wedge Belts result in drives that are extraordinarily compact. They are capable of handling even more than twice as much power in a given space as traditional V-Belt drives. 

Special Polyester Cord Cables provide the strength and flexibility needed for immense load carrying capacity of these small sections and an exclusive process of bonding the cables to the rubber element of the belts ensures that all parts of the belts act in unshakable union under conditions of severest flexing. The benefits of Wedge Belts go beyond compactness and low initial cost. Every Wedge Belt is highly resistant to heat, oil, and exposure to weather and has adequate electrical conductivity to deal with normal static hazards. 

Wedge belts are narrow V-belts with an aspect ratio of around 0.8. (Aspect ratio = Topwidth/ Height of the belt cross-section). The Top width is the same but the height is significantly larger than that of classical belts. Please refer to the Table below.

Classical Belts		Wedge Belts
Section	Cross Section (mm)	Section	Cross Section (mm)
Z	10X6	SPZ	10X8
A	13X8	SPA	13X10
B	17X11	SPB	17X14
C	22X14	SPB	22X18

 

• Lesser number of Wedge belts for transmitting the same power means lesser shaft overhang, lower shaft moments and lower load on bearings, apart from compactness of design.
• Increased height of the cross section ensures better and even support for all the cable cords leading to uniform distribution of stresses and consequently power. Higher belt velocities are possible with wedge belts, the recommended limit being 40 m/sec.

 
Features:

• Specially Designed Polyester, blended with cotton fabric and impregnated with Special Synthetic Rubber.
• Strong, flexible, crack-resistant, high-modulus, low-stretch polyester cords
• Precision-built(PB) with base rubber made of special polymers.
• Unique “HSS” Process of Heat Stretching and Length Stabilizing ensures uniform tension on the drive and maximum life.
• Knurl finish and raised lettering for improved aesthetics.

 

Space Saver Wedge: Higher cross-section for better and complete support to the load-bearing parts ensuring uniform distribution of stress and power.
