Decoding SKF 51340 M
- 513Series
- Thrust ball bearings, 513 series. Series differ in outside diameter and width even when the bore is the same.
- 40Bore
- Bore 200 mm (40 × 5).
- MSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
51340 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 51340 M measures 200 mm across the bore and 340 mm across the outside diameter; its height is 110 mm (200 x 340 x 110 mm).

SKF thrust ball bearings in the 511 M series are designed to handle axial loads in a single direction. They are found in gearboxes, pumps, and compressors where axial capacity and rigidity are required. The single-row ball arrangement and cylindrical bore shaft ring make mounting straightforward and support precise operation. MR Industrial Accessories supplies this series as part of its SKF bearing range.
The part number 51130 M breaks down as follows: the 511 prefix identifies a single-direction thrust ball bearing from the 511 series. The next two digits, 30, are the diameter code that sets the bore size for this series. The M suffix means the cage is machined brass, offering greater strength and suitability for high speeds. Other sizes in the series include 51132 M, 51134 M, and 51136 M, which follow the same design with different dimensions.
These bearings appear in petrochemical, cement, steel, and food processing operations. They are common in centrifugal pumps, industrial fans, gearboxes, and rotary tables. Because they support axial loads, they suit applications where the shaft must be held in a vertical or horizontal position under unidirectional thrust. Lifting equipment and machine tool spindles also use them.
When selecting a bearing, consider the axial load, rotation speed, and environmental conditions. Check that the housing and shaft have adequate hardness and roughness. Lubrication may be grease or oil, depending on the application. Correct alignment between shaft and housing is essential to avoid additional loads. Use suitable tools during mounting to prevent damage to the rings.
For equivalences, SKF 511 M series thrust ball bearings can be interchanged with products from other brands that follow the same dimensional designation. Always verify tolerances and cage type, as these can vary between manufacturers. For replacements, consult a specialist and provide the complete part number. MR Industrial Accessories supplies SKF and offers technical support.

Frequently asked questions
- SKF 51340 M bearing: what are its dimensions?
- SKF 51340 M measures 200 mm across the bore and 340 mm across the outside diameter; its height is 110 mm (200 x 340 x 110 mm). Those are the boundary dimensions standardized in ISO 104 for basic designation 51340.
- What does the suffix M mean in an SKF thrust ball bearing?
- The M suffix indicates a machined brass cage. This provides greater strength and makes the bearing suitable for high-speed or more demanding applications.
- Does this bearing support radial loads?
- No, thrust ball bearings are designed mainly for axial loads in one direction. For radial loads, other bearing types are required.
- How can I know if an SKF thrust ball bearing is compatible with my equipment?
- Check the bore, outer diameter, and width dimensions against those of the original bearing. Also consider axial load and operating speed. Contact us with the part number and we will advise you.
