Deep Groove Ball Bearings SKF 61800
SKF’s compact deep-groove ball bearing 61800, measuring 10 × 19 × 5 mm, for space-saving shaft mountings in industry and precision engineering.
The SKF 61800 single-row deep groove ball bearing is designed for applications with very limited installation space. With an inside diameter of 10 mm, an outside diameter of 19 mm and a narrow width of 5 mm, this design is classified as a thin-section bearing. The open bearing, made from standard rolling-element bearing steel 100Cr6, primarily accommodates radial loads as well as moderate axial forces. Thanks to its sheet steel cage and standard radial clearance, it is suitable for constant speeds in many industrial applications.
What is the 61800 deep groove ball bearing suitable for in industrial applications?
Design engineers primarily use this narrow roller bearing where compact dimensions and low weight are required. It is used in compact drive units as well as in precision mechanical mountings with very limited installation space. As the bearing is open at both ends, lubricant can circulate freely. However, this requires a clean installation environment or an external housing seal to protect against dirt particles and moisture.
What are the key features of the open design with a sheet steel cage?
The open design, without integrated sealing washers, keeps rotational resistance low and allows flexible lubrication with oil or grease. The guided sheet steel cage maintains a uniform spacing between the rolling elements and is designed for a temperature range of –20 to +120 degrees Celsius. Manufactured to tolerance class P0 (ABEC 1) and without a ring groove or flange on the outer ring, the 61800 deep-groove ball bearing can be fitted directly into cylindrical housing bores.
What design advantage does the 61800 deep-groove ball bearing offer?
As a thin-section bearing, the 61800 deep-groove ball bearing is characterised by a particularly narrow cross-section with a shaft diameter of 10 mm. Design engineers use this design to minimise the installation space required and reduce the weight of rotating assemblies, without compromising on the precise guidance provided by a single-row radial ball bearing.
What are the dimensions of this roller bearing?
The bearing has a bore of 10 mm, an outside diameter of 19 mm and a width of 5 mm. The outer ring is cylindrical in shape and has neither a flange nor a retaining ring groove, which facilitates installation in standardised housing seats.
Why does the 61800 deep-groove ball bearing have an open design?
The open design does not feature integrated seals, which means there is no sliding friction against the cover plates. You should opt for this variant if the bearing operates in a sealed oil bath or if the housing is already protected against contamination by external sealing elements.
What does the specification for standard radial bearing clearance mean?
The standard bearing clearance refers to the manufacturer’s specified clearance between the rolling elements and the raceways when the bearing is in its unassembled state. This standard value helps to ensure that, once pressed onto the shaft and subject to operational heating, the rolling elements roll freely without any harmful jamming occurring.
Within what temperature range can the bearing be operated?
The permissible operating range is from -20 to +120 degrees Celsius. This range is limited by the 100Cr6 material and the sheet steel cage. When selecting a lubricant, you should ensure that the grease or oil is also suitable for these temperatures.
Which tolerance class does the component fall into?
The component complies with tolerance class P0 or PN, which corresponds to class ABEC 1. This classification covers the standard dimensional and runout tolerances in mechanical engineering and ensures consistent runout on dimensionally accurate shafts.
