Main Spindle Bearings - NTN Glob

preload for DF, DB, and DT sets, but it is possible only if the combined bearings have the same clearance/preload symbols. The flush grinding technique is employed for standard BNT series, 0 series, and 2 series bearings designed for main spindles of machine tools, and for 2A-BST thrust angular contact ball bearings

Ball & Roller Bearings - Pooley In

DB and DF matched pair bearings and double-row bearings can accommodate radial load and axial load in both directions. DT matched pair bearings are used for applications where axial load in one direction is too large for one bearing to accept. □ HAR type high speed bearings were designed to contain more balls than.
