The 217001 set is engineered to replace high-friction plastic bushings or worn-out factory bearings. In the world of 1/18 scale racing, where motors are small and every bit of torque counts, a "draggy" bearing is the same as a slow car. These bearings ensure that your drivetrain and steering components spin with near-zero resistance.
Detailed Technical Specifications
1. High-Precision Chrome Steel
-
Reduced Rolling Resistance: Manufactured to strict tolerances to ensure a smooth, vibration-free rotation at the 30,000+ RPMs seen in brushless power systems.
-
Durability: Chrome steel races and balls provide superior hardness compared to standard carbon steel, resisting "pitting" and flat-spotting under heavy landings.
2. Performance Sealing
-
Low-Friction Protection: These bearings typically feature high-quality shields or seals designed to keep track grime and carpet fuzz out of the internal raceways while maintaining a low-drag profile.
-
Pre-Lubricated: Factory-treated with a lightweight high-speed oil, making them ready for immediate "drop-in" competition use.
3. Critical Fitment Applications
While these bearings fit various custom applications, they are most commonly used in:
-
Steering Bellcranks: Replacing bushings with bearings here eliminates steering "stiction" and allows your servo to center the wheels more accurately.
-
Gearbox/Transmission: Used on specific internal shafts within the Mini-T 2.0 and Mini-B transmission to ensure maximum power transfer to the rear wheels.
