Timken MM35BS72QUH Angular Contact Ball Bearing Quad Set

Timken MM35BS72QUH is a super precision angular contact ball screw support bearing quad set designed for high-accuracy CNC machine tool spindles and ball screw support systems. The quadruplex arrangement contains four bearings (bore 35 mm, outside diameter 72 mm, width 15 mm per bearing) for a total set width of 60 mm, with a 60° contact angle and steel balls in a phenolic outer land riding cage. Dynamic radial load rating Ce is 36,300 N and static radial load rating C0 is 45,400 N, with limiting speeds of 2,900 rpm (grease) and 5,800 rpm (oil) to support high-speed operation and precise positioning. Common applications include CNC machining centers, precision milling machines, CNC lathes, and grinding machines, or other high-precision automation equipment, and common replacements include SKF BSD3572CG-4, NSK 35TAB07U/GMP4, and FAG BSB3572-SU-4.
