Decoding RKB 51412
- 514Series
- Thrust ball bearings, 514 series. Series differ in outside diameter and width even when the bore is the same.
- 12Bore
- Bore 60 mm (12 × 5).
51412 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
RKB 51412 measures 60 mm across the bore and 130 mm across the outside diameter; its height is 51 mm (60 x 130 x 51 mm).

When a shaft carries a load along its axis rather than across it, an RKB thrust ball bearing is often the right choice. This bearing uses balls and raceways to handle predominantly axial forces in a single direction, running smoothly in equipment where weight or force must travel along the shaft. You will find it in conveyors, mixers, lifting gear and similar machinery.
The series code tells you the bore size: a base number identifies bore and outer diameter. For example, 510/500 is a thrust bearing with a 500 mm bore. In 510/530, 510/560 and 510/600, the digits after the slash give the bore in millimeters. Suffixes can signal design variants such as steel or brass cages, or special tolerances. Always check the manufacturer's tables to read a code correctly.
These bearings appear in food processing, cement, steel and mining operations. They suit grinding equipment, presses, cranes and table rotation systems, as well as gearboxes and clutch mechanisms. Their strength in axial load makes them a fit wherever force is transmitted along the shaft, such as drill columns or propeller shafts.
Selection starts with the axial load, rotation speed and environmental conditions. Because the bearing is not self-aligning, confirm that shaft and housing line up properly. Mounting surfaces must be parallel and rigid. Grease or oil lubrication works depending on the application. Sealing depends on contaminants; in dirty settings, add extra protection.
Thrust ball bearings from different brands can be interchanged when the main dimensions and load capacity match. European and Asian equivalents are common. To find a replacement, compare bore, outer and height diameters plus axial capacity. MR Industrial Accessories can help you identify a compatible alternative.

Frequently asked questions
- RKB 51412 bearing: what are its dimensions?
- RKB 51412 measures 60 mm across the bore and 130 mm across the outside diameter; its height is 51 mm (60 x 130 x 51 mm). Those are the boundary dimensions standardized in ISO 104 for basic designation 51412.
- What does the code 510/500 mean?
- It identifies a thrust ball bearing with a 500 mm bore. The digits after the slash give the bore in millimeters. For outer diameter and height, consult the manufacturer's tables or ask for the data sheet.
- Does this bearing support radial loads?
- Thrust ball bearings are intended mainly for axial loads. Using them for significant radial loads is not recommended because their capacity in that direction is limited. For combined loads, consider other bearing types.
- How can I request a quote?
- Send the part number or the bearing dimensions via WhatsApp or email. We will reply promptly with the information you need. If the designation is unclear, we can also help you identify it.
