Cost effective Non-Pull Out with Improved Vibration Dampening
Our Non-Pull out design utilizes a standard 3mm hardened dowel pin. This pin can be used to secure a Weldon flat or any radial groove. Due to the mass of the BC locking nut and the un-like materials BC provides superior vibration dampening over shrink systems. Adding the grease to the taper as shown in the video provides higher locking torques and easy dis-assembly. This modification is performed at Pioneer in Elk Grove Village, IL. We can locate the pin to match up with your cutting tool. Please note the minimum depth of insertion of the cutting tool to create a coolant seal.
