Thin Section Bearing Introduction



Thin Section Bearins Overview                  

DRE product line consists of a family of seven open and five sealed series of thin section bearings ranging in bore diameters from 1.000 inch to 40.000 inch. Series range from 187 x .187 inch to 1.000 x 1.000 inch in cross section. When required, we can provide internal fit up, lubricants, separators and other features to meet the most demanding application requirements. To obtain corrosion resistance,DRE can provide corrosion protection series of bearings which are equal to or better than a full AISI 440C stainless steel bearing and can be supplied with very short lead time.We also have stock for thin section bearing.
