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.
We have the below types for your reference:
Open Radial Contact Thin Section Ball Bearings (KAA,KA,KB,KC,KD,KF,KG series)
Open Angular Contact Thin Wall Ball Bearings (KAA,KA,KB,KC,KD,KF,KG series)
Open Four Point Contact Thin Section Ball Bearings (KAA,KA,KB,KC,KD,KF,KG series)
Sealed Radial Contact Thin Wall Ball Bearings (JHA,JA,JB,JU.JG series)
Sealed Four Point Contact Thin Section Ball Bearings ( JHA,JA,JB,JU,JG series)
