OPTIBELT Catalogs

Optibelt is a global reference brand for power transmission belts in both industrial
and aftermarket applications. Reliability, energy efficiency, and long service life are the pillars
behind its solutions: from classic and narrow V-belts to rubber and polyurethane synchronous belts,
and ribbed belts for compact drives. On this page you’ll find the official Optibelt catalogs,
designed to help you quickly select the right product, size your drive, and plan installation and
maintenance according to best engineering practices.

What you’ll find in the catalogs

• Range overviews: classic and narrow V-belts (SPZ, SPA, SPB, SPC and classic profiles), synchronous belts (OMEGA, OMEGA HP/HL) and polyurethane belts (ALPHA, ALPHA FLEX), Poly-V (RB), and variable speed belts.
• Dimensional tables: nominal/effective lengths, sections, pitches, tolerances, minimum pulley diameters, tooth profiles.
• High-performance lines: SUPER XE-POWER PRO M=S, RED POWER, BLUE POWER for higher loads and extended maintenance intervals.
• Selection guides: service factors by machine type, corrections for environment and duty cycle, application examples.
• Installation & maintenance: pulley alignment, initial tensioning and periodic checks, wear inspection, safety, storage.
• Useful tools: measurement conversions (Li/Lw/La), profile equivalences, notes on materials and cords, guidance on noise and efficiency.

Why choose Optibelt

• Efficiency & stability: premium compounds and cords to maintain performance over time and reduce re-tensioning.
• Operational reliability: engineered for shock loads, frequent starts, and harsh environments.
• Complete portfolio: from general maintenance to high-performance drives for compressors, pumps, HVAC, machine tools, packaging, food & beverage, and quarry/mining.

How to choose the right belt (quick method)

1. Define the application: power/speed of driver and driven shafts, daily hours, start cycles, ambient conditions.
2. Select the family: V-belt (robust and simple), synchronous (phase accuracy and efficiency), Poly-V (compact and smooth), PU (modularity and endless/joined options).
3. Size the drive: choose profile and pitch, check transmittable torque, minimum pulley diameters, wrap angles and center distance.
4. Mechanical verification: number of grooves, ratio, rim speeds, expected vibration and noise.
5. Install correctly: align pulleys, set tension per table, and re-check after the initial run-in period.

Highlighted product lines

• SUPER XE-POWER PRO M=S: next-gen V-belts for high specific power and long life.
