SPZ 1000 FTD RICH Toothed V-Belt – 9.7 x 8 mm Section – 987 mm Inside Length

Reference Standard

All RICH SPZ series belts follow ISO 4184 / DIN 7753, which define the Pitch Length (Lp) as the reference dimension. Inside Length (Li) and Outside Length (La) are derived using fixed offsets. Some suppliers may publish different values due to alternative measurement systems, but these refer to the same SPZ belt.

Key Advantages

• Superior Flexibility: Toothed design allows use with smaller pulley diameters and ensures efficient power transfer.
• High Efficiency: Reduces heat build-up and energy loss compared to wrapped belts.
• Enhanced Durability: Reinforced rubber and polyester cords provide excellent wear resistance and tensile strength.
• Precision Fit: Guarantees optimal transmission and reduced slippage.

Transparency Note

Lengths shown follow ISO 4184 / DIN 7753, using Pitch Length (Lp) as the reference. Some suppliers may list different Inside Length (Li) values due to alternative or proprietary measurement systems (e.g., Li = 900 mm for an SPZ 937), but these represent the same belt expressed under different conventions. RICH specifications ensure international consistency, traceability, and technical neutrality.
