SKF 61811 Series Ball Bearing, 72mm Outside Diameter, 55mm Inside Diameter - 61811-2RZ
This ball bearing is designed to provide rotational support in machinery where sealed, steel components are required for durability and contamination resistance. It fits into assemblies requiring a cylindrical bore and offers single-row deep-groove performance for radial and moderate axial loads in both directions. The sealed ends help maintain internal conditions while the sheet-metal cage supports internal elements during operation.
Features and Benefits:
• Sealed end type reduces ingress of contaminants
• Steel balls deliver robust rolling-contact performance
• Single-row deep-groove design supports bidirectional axial loads
• Sheet-metal cage maintains ball spacing under load
• CN internal clearance compensates for thermal expansion
• Dynamic load capacity 8.84 kN enhances load-bearing life
• Steel balls deliver robust rolling-contact performance
• Single-row deep-groove design supports bidirectional axial loads
• Sheet-metal cage maintains ball spacing under load
• CN internal clearance compensates for thermal expansion
• Dynamic load capacity 8.84 kN enhances load-bearing life
Applications
• Suitable for electric motor shaft support
• Ideal for conveyor roller axles
• Used with gearbox idler shafts
• Can be used for pump rotary assemblies
• Suitable for industrial fan spindle bearings

What bore Interface does it require for installation?
It requires a cylindrical bore sized to the specified inside diameter for a press or interference fit.
How does the internal clearance affect operation under temperature change?
The CN internal clearance provides a nominal axial and radial gap that accommodates moderate thermal growth without excessive preload.
What rotational speed can be expected in typical service?
The component is rated for a limiting speed of 9,500 r/min under appropriate lubrication and load conditions.
How do the static and dynamic capacities relate to service selection?
The static rating of 6.8 kN indicates resistance to non-rotational loads during stoppage, while the dynamic rating of 8.84 kN indicates fatigue life under continuous rotation.
Which structural elements assist in maintaining cage stability at high speeds?
The sheet-metal cage restrains rolling elements and preserves geometry to limit skidding and maintain separation at elevated speeds.
