SPS uses various styles of seals when rebuilding spindles. Lip seals are used on slow-turning spindles because they make shaft contact and generate heat. When spindle speeds increase, we go with the brass non-contact seals to keep debris out of the bearings. Some seals, like those made by Garlock, replace the whole front cover of the spindle. Using quality spindle seals, some of our customers have seen up to a 60% reduction in spindle failures.
