SKF Single Row Deep Groove Ball Bearing 55 mm ID, 72 mm OD, 9 mm Race Width, Sealed Sheet Metal Cage 61811-2RZ

SKF 61811-2RZ is a high-quality single row deep groove ball bearing featuring a 55 mm inside diameter and 72 mm outside diameter with a 9 mm race width. The bearing includes sealed ends with a sheet metal cage and steel balls, designed to provide reliable rotational support in industrial machinery. Its design supports bidirectional axial loads, making it ideal for various mechanical applications.

The sealed end type significantly reduces ingress of dirt and contaminants, enhancing durability and longevity in harsh environments. The sheet metal cage maintains ball spacing and ensures cage stability even at high rotational speeds.

The CN internal clearance accounts for thermal expansion ensuring smooth operation under temperature variations without inducing excessive preload. This bearing maintains high performance with a limiting speed of up to 9500 rpm, suitable for high-speed industrial applications.

Static and dynamic load ratings measure the bearing's capacity to withstand non-rotational and rotational forces, respectively; with a static load rating of 6.8 kN and dynamic load rating of 8.84 kN, this bearing delivers excellent fatigue resistance and operational reliability.

Applications encompass electric motor shaft supports, conveyor roller axles, gearbox idler shafts, pump rotary assemblies, and industrial fan spindle bearings, making it a versatile choice across manufacturing, HVAC, and mechanical equipment sectors.
