PIX - X'tra Raw Edge Belts

Raw Edge belts, as the name implies do not have textile wrapping on the outer surface. These are produced by slitting individual belts from rubber sleeve and hence they are called as Cut edge belts.

The manufacturing methods also make it simpler to produce belts with cogs underside thereby reducing the bending resistance of the belts and allowing them to operate on pulleys with approximately 20% smaller diameters. The decreased bending resistance reduces mechanical losses during bending and leads to improved efficiency and reduced working temperature. Heat dissipation is further improved by the larger area between the belt and the surrounding atmosphere and also by the air turbulence around the cogs during operation. Multi stage drives can be eliminated. These belts require a higher tension than the wrap belts so as to exhibit higher power transmission capability.

Raw Edge Belts are of three types:
(i) REC Belts (Raw Edge Moulded Cogged Belts)
(ii) REP Belts (Raw Edge Plain Belts)
(iii) REL Belts (Raw Edge Laminated Belts)

Features:
Special top layer with fabric
The rigid layer on the top restricts top layer cracking and gives uniform tension on cord ends. Top fabric gives better support & protection from environment.

Tough Tensile Member For Greater Strength
Specially treated stabilised polyester cord provides high tensile strength with minimum
stretch which in turn gives V-belt superior resistance to fatigue & shock loads.

Moulded Cogs
Moulded cogs allow the Raw edge cogged belts to operate even over smaller diameter
pulley at high speeds. The cogs also help in reducing the bending stress apart from
providing the higher surface area for proper heat dissipation.

Polychloroprene Cushion Rubber Compound
Ensures the best possible bond between the base compound, the tension cord & rubber impregnated fabric top surface that provides long service without cord separation.

Fibre Filled Polychloroprene Base Compound
Gives increased power transmission capability, superior transverse stiffness & high wear resistance.

Speed ratios up to 1:12 are possible
This eliminates the need for multi stage drives.
Temperature range: -180C to +1000C 
Maximum recommended belt speed is 30 m/s*
Antistatic Oil and Heat resistant
ATEX certified FRAS belts are also available

Applications: It is recommended to use these belts in borderline cases if difficulties are anticipated in using wrap construction belts.

 

PIX- X'tra Raw Edge Plain Belts

PIX- X'tra Raw Edge Laminated Belts

Construction:
Raw Edge Plain Belts (REP) may or may not have a fabric layer at the bottom, but Raw Edge Laminated Belts (REL) will have more than one bottom layer. As a result they are excellent in resistance to transverse compression.
