What this part is

SKF 7026 CDGA/P4A super-precision, high-capacity, universally matchable single-row angular contact ball bearings. Bore Diameter: 130 mm. Outside Diameter: 200 mm. Overall Width: 33 mm. Contact Angle: 15°. 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: 3.18 kg (7.01 lb) per bearing.

Decoding the designation

70 — ISO light dimension series 10. A 130 mm bore carries a 200 mm outside diameter in a 33 mm section.

26 — bore code. 26 × 5 = 130 mm.

C — 15° contact angle. The shallow angle favours running speed and radial stiffness.

D — high-capacity internal design.

GA — universally matchable, extra light preload.

P4A — SKF super-precision tolerance class: P4 dimensional accuracy with running accuracy held tighter still.

What these specs mean in practice

Dynamic Load Rating: 148,000 N. Static Load Rating: 156,000 N. Both figures are per bearing. At this section the static rating sits above the dynamic one, which is normal for the 70-series light section and sets a high permanent-deformation limit at rest.

Contact Angle: 15°. Radial load is carried together with axial load acting in one direction. Contact type is normal, two-point. Both rings are one piece.

Closure Type: Open, supplied unlubricated and preserved for spindle-shop cleaning and grease or oil charging at build.

Mounting data

Mounting Arrangement: universally matchable back-to-back, face-to-face or tandem. Bore Type: Straight. Item Weight: 3.18 kg (7.01 lb) per bearing. Harmonization Code: 8482.10.50.

Quantity and configuration

Unit Quantity: 2 Pcs. Two universally matchable GA-class bearings, mountable in any of the three arrangements or usable singly.

Interchange guidance

Same envelope, same 15° angle, same super-precision class: Timken/Fafnir 2MM9126WICRSUL, FAG B7026-C-T-P4S-UL, NSK 7026CTRSULP4, RHP 7026X2TRSULP4.

Preload class is part of the identity. GB (light preload) and GC (medium preload) are different parts on the same envelope.
