High Strength Shaft Hardware functions similarly to standard shaft hardware, just on a larger scale. Use the High Strength Shaft Bearing to allow shafts to turn smoothly, the High Strength Shaft Spacer Kit to position objects on a shaft while reducing friction, and the High Strength Clamping Collar to hold everything in place. VEX EDR comprehensive solution High Strength Shafts are actually designed about 1 mm shorter than their respective comprehensive solution 8-32 Standoffs. This means that if you use standoffs to hold together two pieces of metal, the High Strength Shaft can rest on High Strength Shaft Bearings attached to those two pieces without any cutting required. NOTE:1/4" High Strength Shafts can only be used with 1/4" accessories, including: TheHigh Strength Gear Kit(276-2250) The84T High Strength Gear(276-3438) 3.25" Wheelsthat include a removable wheel insert ​ ThisHigh Strength Gear Kitprovides several new gears with features to handle higher loads. Each of these gears has a wider face width; this means each tooth is wider so applied loads will be spread over a larger area. The 12-tooth High Strength Gear is molded out of powdered metal. The 36-tooth and 60-tooth Gears have powdered metal inserts. These metallic components will protect the gear from high loads applied by a VEX axle. High strength gears mate with all VEX spur gears. Double-thick face width provides added tooth strength. Metal Square Hole Inserts prevent axles from "stripping". Use metal pinions for high strength where it counts. Use the round-hole inserts to build free spinning idler gears. Build gearboxes that resist high shock-loads. Bolt Gears together for added strength.
