Therefore, this criterion applies only when the fit surface has a width sufficient as a reference face. 3 When determining a tolerance for permissible form accuracy, the reference dimensions used are shaft diameters da and db. For example, when using a JIS class 5 bearing for a dia. 50 mm shaft, the tolerance of roundness is

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.
