Decoding SKF 51276 F
- 512Series
- Thrust ball bearings, 512 series. Series differ in outside diameter and width even when the bore is the same.
- 76Bore
- Bore 380 mm (76 × 5).
- FSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
51276 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 51276 F measures 380 mm across the bore and 520 mm across the outside diameter; its height is 112 mm (380 x 520 x 112 mm).

For equipment that handles thrust in a single direction, the SKF 511 Series thrust ball bearing provides a straightforward solution. It is built to carry axial loads and is commonly found in gearboxes, pumps, compressors, and spindles. The design uses balls running between flat washers to keep operation smooth. MR Industrial Accessories supplies this series and can help you match the right size to your application.
Reading the part number is the first step in selecting a replacement. The 511 prefix identifies a single-direction thrust ball bearing with flat washers. A suffix such as F points to a stamped steel cage. In designations like 51172 F and 51180 F, the digits 51172 or 51180 set the bore and outside diameter, while the F confirms the cage type. Understanding this structure simplifies ordering and cross-referencing.
These bearings appear in demanding industries including metallurgy, cement, paper, and food processing. Typical uses are low-speed, high-axial-load positions: rotary tables, presses, vertical centrifugal pumps, gear reducers, and lifting equipment. They also show up in steel production machinery, flour mills, and aggregate processing plants. When radial forces are minimal and thrust is the main load, this bearing type is a practical choice.
Proper selection depends on the axial load, rotation speed, and operating environment. Alignment between the washers is critical because these bearings cannot accommodate angular misalignment. Lubrication with grease or oil helps extend service life and minimize wear. In contaminated settings, add extra sealing protection. During mounting, keep the support surfaces flat and parallel to prevent eccentric loads that can damage balls and raceways.
Interchangeability is possible with thrust ball bearings from other manufacturers that share the same dimensional designation, such as FAG, NSK, or NTN. However, tolerances and cage styles can differ, and not every suffix matches. Always compare the bore, outside diameter, and height before substituting. Our team can advise on equivalents without risking equipment performance.

Frequently asked questions
- SKF 51276 F bearing: what are its dimensions?
- SKF 51276 F measures 380 mm across the bore and 520 mm across the outside diameter; its height is 112 mm (380 x 520 x 112 mm). Those are the boundary dimensions standardized in ISO 104 for basic designation 51276.
- What does the F suffix mean in an SKF thrust ball bearing?
- The F suffix indicates a stamped steel cage. This cage guides the balls and handles moderate temperatures. Check that the cage suits your lubrication and speed conditions.
- Does this bearing support radial loads?
- No, thrust ball bearings are designed for predominantly axial loads. Radial loads should be minimal or none. If your application combines axial and radial loads, consider another type such as an angular contact bearing.
- How is a thrust ball bearing mounted?
- Mount it with the washers aligned and the support surfaces flat and parallel. Apply the axial load uniformly. Do not strike the washers during mounting, and lubricate properly before start-up.
