Specifications Repeat Robotics 2207 Hubmotor Weapon Shaft While we offer this shoulder bolt and locknut as a weapon shaft for the 2207 as a convenience, the actual length of the shoulder bolt should be based on the motor thickness plus the thickness of the uprights holding the weapon drive. The 1.5″ thickness we offer is for two 1/4″ supports. Other sizes are readily available from most hardware sources. Specifications Shaft Length 1.5″ Shaft Width 0.25″ / 6.35mm Threads 10-24 Locknut Type Nylon Hex Size SAE 1/8″ Nut Size (Socket) SAE 3/8″ weight (shoulder bolt locknut) 15g / 0.53oz Notes A 1/4″ shoulder bolt or similar through shaft is required for use. Without the shoulder bolt, the rotor is not fully constrained and may be damaged. The 1/4″ x 1.5″ shoulder bolt is great for bots with 2x 0.25″ uprights. The 2207 hub motor drivetrain is designed to be used in combat, where anything can happen. The manufacturer is unable to accept returns for battle damaged products. ItGresa Robotics is proud to support the builder community by offering and marketing their products.
