- Patented design provides superior belt alignment and tension for improved drive efficiency and life
- Long-lasting steel pulleys with dust shields to protect internal bearings from contamination
- Double row bearings carry more load and last up to 3X longer than two individual bearings
- Chrome-silicone round torsion spring for less flex-fatigue than flat-spring designs
- Optimized components engineered for maximum strength and durability
