RPP rubber timing belts are high-performance curved-tooth belts designed for precise power transmission, high load capacity, and significantly reduced wear compared to traditional trapezoidal belts. With stable operation in dusty, oily, or high-temperature environments, RPP belts are widely used in plastic molding machines, woodworking machines, textile machinery, packaging lines, ceramic production, and many precision mechanical systems. At Belota, we supply the full range of Megadyne RPP ISORAN and RPP SILVER 2 series – globally recognized for durability, accuracy, and superior service life in industrial applications.
Introduction to RPP Rubber Timing Belts
RPP (Round Power Profile) timing belts are an improved generation of round-profile tooth belts designed to replace the conventional trapezoidal tooth structure. The curved tooth profile ensures better load distribution, improved heat dissipation, and extended belt life in high-power transmission systems.
RPP belts are widely used in industries that require high precision, durability, and load capacity, such as textiles, woodworking, ceramics, packaging, food processing, and industrial machinery.
Technical Specifications of RPP Timing Belts
RPP belts are available in various pitches depending on the system’s power requirements:
- RPP 3M: Pitch P = 3 mm, Height H = 2.3 mm
- RPP 5M: Pitch P = 5 mm, Height H = 3.4 mm
- RPP 8M: Pitch P = 8 mm, Height H = 5.4 mm
- RPP 14M: Pitch P = 14 mm, Height H = 9.5 mm
These specifications ensure perfect compatibility with corresponding pulleys in synchronous drive systems.
Key Features
- High torque transmission with increased efficiency thanks to the curved tooth design.
- Reduced noise and vibration during operation.
- High-quality synthetic rubber for excellent wear and heat resistance.
- Stable performance in oily, dusty, or humid conditions.
- Compatible replacements for HTD, Poly Chain®, or RPC belts.
- Easy installation, low maintenance, and extended service life.
Common Applications
RPP timing belts are widely used in:
- Plastic injection molding machines, CNC equipment, printing machines, packaging systems.
- Production lines for ceramics, paper, food, and packaging materials.
- Textile machinery, woodworking machines, and industrial mechanical systems.
- High-precision synchronous drive applications.
