Companies worldwide trust Retlaw Industries to produce custom thermoplastic idler pulleys used in belt-driven systems. As a start-to-finish manufacturer, Retlaw performs all phases of the pulley production process in-house, including design and engineering, tooling, molding and assembly.

Benefits of Plastic Idler Pulleys
| Plastic Pulleys | Metal Pulleys | |
|---|---|---|
| Weight | Lightweight — easier handling, lower shipping & installation costs | Heavier — adds system weight |
| Corrosion & Solvent Resistance | Won’t corrode in damp, oily or dirty environments | Prone to rust, corrosion and solvent damage |
| Friction, Heat & Noise | Lower friction and heat transfer — quieter operation | Higher friction and more heat transfer |
| Fatigue & Design Durability | Single-piece molded — no rivet fatigue, resists high-speed fatigue | Multi-piece — prone to rivet fatigue and separation |
| Maintenance & Lifespan | Longer pulley and belt life, less maintenance needed | More frequent maintenance, shorter lifespan |
