A FAG B7021-C-P4-UL super precision single-row angular contact ball bearing. Bore 105 mm, outside diameter 160 mm, width 26 mm, in the ISO 7021 envelope. Open faces, universal design.
The B prefix denotes the FAG super precision angular contact series. 7021 denotes the ISO 70 series, bore code 21 giving a 105 mm bore. C denotes a 15° contact angle in the FAG scheme. P4 denotes ABEC 7 precision. U denotes a universal design, ground to stack in any arrangement. L denotes light preload.
A 15° contact angle favours speed and radial stiffness; the 25° FAG execution, coded E, trades speed for thrust capacity. Light preload holds heat generation and running torque down, which suits higher spindle speeds. A single row takes thrust in one direction only.
Bore: 105 mm. Outside diameter: 160 mm. Width: 26 mm. Contact angle: 15°. Precision class: P4, equivalent to ABEC 7. Preload: light. Rolling elements: steel balls, single row. Closure: open both faces.
1 Pc. Universal design, matchable into duplex or triplex sets.
Universal grinding allows this bearing to run alone or to be stacked back-to-back, face-to-face or in tandem, with preload established by the ground ring faces once clamped against square shoulders.
The generic ISO form of this designation is 7021C-P4 at 15°, light preload. A B7021-E variant shares the envelope at 25° and is a related size, as are medium and heavy preload variants.
