SKF Roller Bearing, 45mm Inside Diameter, 65mm Outside Diameter - 81109 TN
This roller bearing is a single-row component designed to support rotating assemblies where axial enclosure is required. It is constructed from steel with a cylindrical bore and a closed-end type, intended for applications demanding Compact radial support and containment within housings. The bearing balances load-bearing capacity with controlled rotational speed for mechanical systems.
Features and Benefits:
• 153 kN static load rating delivers high resistance to stationary loads
• 45 kN dynamic load rating supports moderate rotating loads
• Non-metallic cage reduces friction and noise during operation
• Limiting speed 4,500 r/min permits use in medium-speed mechanisms
• Closed end prevents contamination and retains internal components
• 45 kN dynamic load rating supports moderate rotating loads
• Non-metallic cage reduces friction and noise during operation
• Limiting speed 4,500 r/min permits use in medium-speed mechanisms
• Closed end prevents contamination and retains internal components
Applications
• Suitable for conveyor rollers requiring contained bearings
• Ideal for driven shafts in industrial machinery
• Used for support in gearboxes with moderate rotational speeds
• Can be used for idler rollers in material handling systems
• Appropriate for rotating elements with cylindrical bores

What is the internal bore specification and mounting interface?
The bearing has a cylindrical bore with an inside diameter of 45 mm suitable for slip-fit or press-fit mounting depending on shaft tolerance and application.
What materials affect wear characteristics and maintenance intervals?
The races and rollers are steel while the cage is non-metallic, which typically reduces lubrication frequency due to lower internal friction but requires compatible lubricant selection.
How does the closed end influence sealing and contamination control?
The closed-end type provides a barrier to ingress, aiding retention of lubricant and limiting particulate entry in confined installations.
What dimensional envelope should be considered for housing design?
The outside diameter is 65 mm and the race width is 14 mm, which determine the bore housing and axial space requirements.
How many rolling element rows are present and what does that imply for load distribution?
It is a single-row design, which concentrates load in one plane and is suited to primarily radial load cases with limited axial capacity.
