SKF 71932 ACD/P4A super-precision, high-capacity single-row angular contact ball bearing, supplied to the TBTG375 matched-set execution. Bore Diameter: 160 mm. Outside Diameter: 220 mm. Overall Width: 28 mm. Contact Angle: 25°. Precision Class: P4A. Number Of Rows: 1. Rolling Elements: Ball. Bore Type: Straight. Closure Type: Open. Cage Type: Outer-ring shoulder-guided. Bearing Material: Bearing steel. Item Weight: 2.64 kg (5.82 lb) per bearing.
719 — ISO extra-light dimension series. A 160 mm bore carries a 220 mm outside diameter in a 28 mm section.
32 — bore code. 32 × 5 = 160 mm.
AC — 25° contact angle. The higher angle carries more axial load and raises axial stiffness.
D — high-capacity internal design.
P4A — SKF super-precision tolerance class: P4 dimensional accuracy with running accuracy held tighter still.
TBT — triplex set arrangement: two bearings in tandem sharing thrust in one direction, the third set back-to-back against them to take thrust the other way.
Dynamic Load Rating: 124,000 N. Static Load Rating: 153,000 N. Both figures are per bearing. At this section the static rating sits above the dynamic one, which is normal for the extra-light 719 series and sets a high permanent-deformation limit at rest.
Contact Angle: 25°. Radial load is carried together with axial load acting in one direction, with the steeper load line favouring thrust capacity and axial stiffness over top speed.
Closure Type: Open, supplied unlubricated and preserved for spindle-shop cleaning and grease or oil charging at build. Contact type is normal, two-point. Both rings are one piece.
Mounting Arrangement: TBT triplex — two in tandem, one back-to-back. Bore Type: Straight. Item Weight: 2.64 kg (5.82 lb) per bearing. Harmonization Code: 8482.10.50.
Unit Quantity: 1 Pc. One bearing from a factory three-bearing TBT set, ground to the same matched execution as its two mates.
Same envelope, same 25° angle, same super-precision class: Timken/Fafnir 3MM9332WICR, FAG B71932-E-T-P4S, NSK 7932A5TRP4, RHP 71932X3TRP4.
