BS2-2209-2RSK/VT143 SKF Spherical Roller Bearing With Tapered Bore and Integral Sealing and Relubrication Features 45x85x28mm

In critical production lines, every minute of down ­time costs. Contaminated environments, heavy loads in applications prone to mis ­alignment or shaft deflections are daily issues for many industries. Leaking grease and frequent relubrication in potentially hard-to-reach places also add to growing costs. For many, simply making it to the next planned mainte­nance stop without machine failure is a challenge.

With sealed SKF Explorer spherical roller bearings, you are equipped to meet these challenges. Pre-lubricated with a specially formulated grease and sealed with high-performance contact seals, they can protect the bearing and lubricant from contam ­inants that might otherwise cause premature bear­ing failure. Their high load carrying capacity and ability to accommodate misalignment further helps you prolong bearing service life.
