Tolerance symbols and definitions → table

1) SP tolerances for 1:12 tapered bore → table
2) Tolerances t_Δds and t_ΔDs apply to NNU design bearings with an outside diameter D ≤ 630 mm.
Tolerances t_Δdmp and t_ΔDmp apply to larger NNU design bearings and to N and NN design bearings.
3) Tolerance values have become half the values in accordance with the revised ISO standard (2014) because
SD is defined as perpendicularity of outer ring outside surface axis with respect to datum established from the outer ring face.
