Spindle failure caused by contamination is all too common across all industries. Here we will review sealing options followed by a few tips on how to prevent contamination of your business critical machine tool spindles.<\/p>\n

Contact seals<\/span><\/strong> work the best whereever you can implement them. Unfortunately they wear out and need exchanged regularly. They will not work in High Speed applications due to heat generation caused by friction (rotating surface contact).<\/p>\n

Labyrinth seals<\/span><\/strong> work well in high speed applications but are vulnerable to contamination by design and require strict attention to environment to perform to their peak. They are cost-friendly and maintenance-free.<\/p>\n

Air sealing systems<\/span><\/strong> are a labyrinth seal upgrade. They provide better sealing in the same high speed application. Positive air pressure is forced \u00c2\u00a0through the labyrinth seal from the interior of the spindle to the outside to prevent penetration of contaminants.<\/p>\n

Custom seal systems<\/span><\/strong> are available in different variations. Most of them have certain applications in which they work best. The spindle repair experts<\/a> can upgrade your current seal system or implement a new system better suited to\u00c2\u00a0your application. Sometimes a combianation of sealing systems will be required to achieve the desired result.<\/p>\n
