Repairs for Spindle Bearing Failure Due to Contamination and Other Causes for All Makes and Models

Don’t leave your spindle subject to contamination and a potential crash

Spindle bearing failure, more specifically failure due to bearing contamination, is a common cause of full spindle failure and SPINTEK’s technicians can help. This problem results when substances enter the spindle and usually, because the spindle seal has failed. Contaminants include all foreign substances — airborne and liquid — and are not limited to; coolant ingress, water and/or condensation, poor lubricant storage, low quality coolant, internal component failure, flying chips and careless assembly or repair.

Apart from contamination additional causes resulting in bearing failure are fatigue, overloading, unbalanced tooling, and chip damage. At SPINTEK we believe in prevention, first and foremost and in finding problems before they become emergencies. The unwanted ingress of any substance through your spindle’s seals is preventable with some simple steps.

Among them, do not let dirt and chips build up around the spindle shafts or seals. Before installing tools, clean the spindle tapers and pilot. Do not tighten cold tools in a hot spindle. Change air supply line filters regularly. Do not blow compressed air or coolant into seals. When removing air or lubrication lines for service make sure to bleed them before reconnection. Check your O-rings for wear and tear frequently and replace.

Precision is key, and Ben Franklin was right. “An ounce of prevention…” Prevention, problem solving. That’s what we’re all about.
