All single tapered roller products of the company are optimally designed, thoughstandardizing installation dimensions, so they can be interchangeableworldwide. The internal structure is optimized and enhanced in design,the inner ring raceway, outer ring raceway and roller rolling surfaceare with a crown, eliminating the edge stress concentration andthus in working the apex of the cone surface intersects at apoint of the bearing center line, realizing pure olling, safetyand reliability. This series is ideal for heavy duty andshock loads and already widely used in automobile,mill, mining, metallurgy and plastics machineryamong others.
