Chain Tensioner Wheel Roller Bearing 7/8 Wide

The Ti22 PERFORMANCE Chain Tensioner Wheel Roller Bearing 7/8" Wide (SKU TIP3865) is a precision-engineered idler wheel designed for micro and mini sprint applications where reliable chain management directly impacts performance and longevity. Built with integrated roller bearings, this tensioner wheel maintains consistent chain tension while minimizing friction losses across the drivetrain.

The 7/8-inch width accommodates standard micro and mini sprint chains, while the included roller bearings ensure smooth rotation under load. At just 0.34 lbs, this wheel contributes minimal unsprung weight to the drivetrain assembly—a critical consideration in small-displacement racing where every gram affects acceleration and handling response. The compact dimensions (6 x 1.55 x 8.5 inches) allow straightforward integration into tight engine bay and frame configurations typical of sprint car builds.

This component serves builders and racers who demand reliability in high-RPM applications where chain slack or bearing wear can cause loss of power transmission or catastrophic failure. Ti22 PERFORMANCE specializes in precision drivetrain components for competitive sprint racing, and this tensioner wheel reflects that focus on durability under sustained racing conditions. Whether you're assembling a new micro sprint platform or upgrading an existing chain drive system, proper tensioning is essential to prevent chain jump, reduce noise, and extend both chain and sprocket life.

Micro and mini sprint competitors rely on purpose-built components to maintain consistency lap after lap. This idler wheel, with its integrated bearing design, eliminates the common problem of tensioner slippage or misalignment that plagues improvised solutions. For serious racers building or maintaining a competition-ready micro or mini sprint, the Ti22 PERFORMANCE chain tensioner wheel roller bearing represents a direct investment in drivetrain reliability and power delivery consistency.
