Suffix description

TB	In The Case Of Bearings Of TB Design, The Axial Load Carrying Capacity Of Cylindrical Roller Bearings Was Significantly Improved With The Aid Of New Calculation And Manufacturing Methods. Optimum Contact Conditions Between The Roller And Rib Are Ensured By Means Of A Special Curvature Of The Roller End Faces. As A Result, The Axial Contact Pressures On The Rib Are Significantly Minimised And A Lubricant Film Capable Of Supporting Higher Loads Is Formed. Under Normal Operating Conditions, Wear And Fatigue At The Rib Contact Running And Roller End Faces Is Completely Eliminated. In Addition, Axial Frictional Torque Is Reduced By Up To 50%. The Bearing Temperature During Operation Is Therefore Significantly Lower
