SNFA super-precision angular contact ball bearing in the 71822 envelope, an extra-thin-section spindle bearing. SNFA was a French specialist in high-speed spindle and ball-screw support bearings, acquired by SKF, so SNFA designations are a common obsolescence trail into current SKF super-precision numbering.

Extra-thin-section bearings get a large shaft, spindle nose or rotary table through a bearing without a correspondingly large housing. A 16 mm-wide bearing on a 110 mm bore carries less than a 70-series bearing of the same bore, and the thin ring conforms closely to the housing and shaft it is clamped into, so seat roundness transfers directly into raceway runout.
A 15° contact angle is the high-speed, low-heat choice, running faster and cooler than a 25° bearing at correspondingly lower axial stiffness and thrust capacity.
Application Types: Large-diameter machine-tool spindles; rotary tables; indexing heads; positions where a large shaft must pass through a shallow bearing section.
