📖 The importance of the broken key in competition

In mechanical sports and competitive karting, transmissions undergo a blazing constraints: brutal acceleration pairs, violent decelerations with permanent braking and vibration. A game in the assembly of a hub or pinion can compromise the efficiency of the chassis and driver safety.

Thanks to the addition of 2 positioning pins of Ø7.5 mm spaced 30 mm, this adjustable key provides a mechanical lock reinforced with respect to traditional flat key keys. It is mortimetric to completely remove the axial micro-movements and guarantee an integral transmission of the effort.

🔧 Michel's trick

"Michel, our technical expert, recommends you: when setting up these adjustable pin keys on your axle or sprinkle, check the cleanliness of the bores and housing. EmPart the pins well flat without forcing through not to mark the worn. Remember to regularly inspect the status of pins and clamping screws during your periodic revisions in the paddock. "

⚠️ Security Council: Never use a key whose pins or edges have shear or deformation signs. A game in the mechanical training in the track can result in a loss of control or damage irretrievably your trees and hubs.

❓ FAQ: your frequent questions

Q: What is the interest of the 2 pins of Ø7.5 mm on this key ?

A: The 2 spacé pins of 30 mm allow anchoring and an extremely precise mechanical coupling between the shaft and the components (hub, pinion, pulley), completely eliminating the game and the risk of slippage.

Q: Are these keys adapted only for karting ?

A: Although ideal for karting axles and hubs, they are ideal for many high-performance mechanics and mechanical sports applications that require locking pulleys, flywheels or gears.

Q: Are they sold individually or pair ?

A: This product is provided in set of 2 units, allowing you to simultaneously equip several elements or have a spare part in your toolbox.
