A single-row super-precision angular contact ball bearing in the 72-series, 100 mm bore, 180 mm outside diameter, 34 mm width. It carries radial load together with thrust in one direction and is built to be mounted singly or stacked with like bearings.
7220 — single-row angular contact ball bearing, 100 mm bore, 72 dimension series
C — 15° contact angle in the RHP/Timken scheme
TR — phenolic (laminated fabric) cage
SU — single, universally ground faces
L — light preload when a set is stacked
P4 — ABEC 7 precision class
A 15° contact angle biases the bearing toward speed and radial stiffness, carrying less thrust than a 25° or 40° execution of the same envelope. The phenolic cage is light and self-lubricating, which suits high spindle speeds and grease or oil-mist lubrication, and sets a lower temperature ceiling than a machined bronze cage. ABEC 7 running accuracy holds tight radial and axial runout, the reason this class is used in machine-tool spindles and precision gearboxes.
1 Pc. Universally ground faces allow this bearing to be assembled back-to-back, face-to-face or in tandem with other SU bearings of the same designation, giving light preload in a set.
The bearing seats against a square, clean shoulder, and the loaded shoulder faces the thrust direction marked by the high-shoulder side of the outer ring. Universally ground rings are stacked with the etched face markings aligned per the intended arrangement, and clamping is done through the rings rather than the cage.
Same-spec equivalents are 15° ABEC 7 single universally ground 7220-size bearings under other schemes, such as a Fafnir 2MM220WI CR SUL. Executions of the same 100 x 180 x 34 mm envelope with a 25° angle, a different preload letter or a duplex-only grind are related sizes rather than interchanges.
