Motor Shaft Suitable For Thrust?

Joe AutoDrill · 2011-08-10T14:04:22+00:00

I've got a customer who wants me to make him a chuck to go on to a 5/8" motor shaft. No problem.My question is whether the motor shaft is suitable to receive a chuck since he will be forcing the drill into material with around 400-500 lbs. of thrust.My thinking is that the motor shaft may shift in the housing and damage the motor...Am I right here or are there motors out there designed to take this type of load I'm not aware of, etc.?Regards,Joe Agro, Jr.(800) 871-5022 x11301.908.542.0244Flagship Site: / Pneumatic Drills: Spindle Drills: Tapping: V8013-R

motor external chuck drill bearing

This is what's being suggested. Mount your motor to it's support plate. Choose a thrust bearing through which the motor shaft will pass, and which will support the chuck in thrust, either by supporting the shaft, by letting the chuck ride on the bearing (bad style), or by attaching the chuck to a shaft which passes through (and is supported by) the bearing and is nailed down to the motor.

The "bearing at the rear" variation just puts the thrust bearing at the back, and leaves you hoping that nothing buckles.
