NTN 7212CGD2/GNP4 angular contact ball bearings, supplied as a universally flush ground matched pair. Bore Diameter: 60 mm. Outside Diameter: 110 mm. Overall Width: 22 mm per bearing, 44 mm across the pair. Contact Angle: 15°. Precision Class: ABEC 7 / P4. Preload: Normal. Cage Material: Polyamide. Cage Type: Fibreglass-reinforced, one-piece. Rolling Elements: Ball. Bearing Material: High carbon chrome steel. Bore Type: Straight. Closure Type: Open. Number Of Rows: 1 per bearing. Item Weight: 1.52 kg (3.35 lb) for the pair. Unit Quantity: 2 Pcs.
72 — ISO dimension series 02 angular contact ball bearing, the medium section for a 60 mm bore.
12 — bore code. Multiplied by five it gives the 60 mm bore.
C — 15° contact angle. The shallow angle favours speed and radial stiffness.
G — universal flush ground faces. Inner and outer rings are the same width and the face steps are set at manufacture, so the pair mounts back-to-back, face-to-face or in tandem and reaches the same preload either way.
D2 — supplied as two bearings, matched as a set.
GN — normal preload.
P4 — ISO Class 4, equivalent to ABEC 7.
Dynamic Load Rating: 104,000 N for the pair. Static Load Rating: 99,000 N for the pair. Both figures are the matched-set values, which is why they sit above the single-bearing numbers for a 7212C.
Limiting Speed: 7,700 rpm grease; 10,000 rpm oil. Oil takes heat out of the contact that grease leaves behind, and the gap between the two figures is that cooling.
Contact Angle: 15°. A shallow angle puts more of the load path into the radial direction and lets the bearing run faster. A 25° or 30° execution of the same size trades speed for thrust capacity.
Preload: Normal. Preload sets running stiffness and removes the play that would let a spindle chatter. Because the set is preloaded, there is no running clearance to specify.
Cage Material: Polyamide. The fibreglass-reinforced nylon cage is quiet, light and low-friction, and it suits the speed range this bearing is built for.
Chamfer r: 1.5 mm. Chamfer r1: 1.0 mm. Shaft shoulder da min: 68.5 mm. Inner-ring abutment db min: 65.5 mm. Housing shoulder Da max: 101.5 mm. Outer-ring abutment Db max: 104.5 mm. Abutment fillet ras max: 1.5 mm, r1as max: 1.0 mm.
Inner ring recess diameters d1: 77.0 mm and 96.0 mm. Outer ring D1: 96.0 mm, D2: 102.9 mm.
Universal flush grinding means no custom spacer is needed to reach the stated preload; clamping the rings solid delivers it.
Two bearings, factory matched. Unit Quantity: 2 Pcs. Mounting Arrangement: universally matchable, back-to-back, face-to-face or tandem.
Every cross listed sits on the same 60 x 110 x 22 mm envelope at 15°. The variables that decide whether one is a straight swap are the precision class, the preload level and the grinding scheme, and each cross states where it differs.
A set ground for light preload will not deliver the same stiffness or the same running temperature as a normal-preload set, so match the preload code as well as the size.
Searchable forms of the number: 7212CGD2/GNP4, 7212CGD2GNP4, 7212 CG D2/GNP4, 7212CG D2 GNP4, 7212C.
