The logarithmic profile of the rollers provides superior load distribution. The design of the flange/roller-end contact area reduces edge loading and promotes the formation of a lubricant film even under arduous operating conditions. The optimized finish of all contact surfaces maximizes the effectiveness of the lubricant. These features significantly decrease noise, temperature and vibration levels, and virtually eliminate temperature peaks.
New small sealed SKF Explorer spherical roller bearings with improved performance are pre-lubricated with a specially formulated grease and sealed with highly effective contact seals. The seals retain lubricant in the bearing while resisting the ingress of contaminants that might otherwise cause premature bearing failure.
Thanks to their optimized materials and design, these bearings can deliver robust, reliable performance for the life of an elevator’s drive system.
