SKF Self-aligning ball bearings Series Ball Bearing, 40mm Inside Diameter, 90mm Outside Diameter - 1308 EKTN9/C3


This ball bearing is a self-aligning, double-row unit designed to accommodate shaft misalignment and support rotating components in industrial assemblies. It operates with an open-end configuration and a tapered bore for secure mounting in applications where angular displacement between housing and shaft may occur.

Features and Benefits:


• C3 internal clearance reduces the risk of internal contact at elevated temperatures
• 9,500 rpm limiting speed supports high-speed rotational applications
• 33.8 kN dynamic load rating extends service under fluctuating loads
• 11.2 kN static load rating resists heavy static forces during stoppage
• Non-metallic cage reduces friction and lowers noise generation
• Steel balls provide consistent rolling contact and wear resistance

Applications


• Suitable for agricultural machinery with shaft misalignment
• Ideal for high-speed pumps and electric motors
• Used with tapered adaptor sleeves for mounted shafts
• Can be used for conveyor rollers under variable loading
• Used for industrial gearboxes requiring radial and angular support

How is the bearing mounted on the shaft with the tapered bore?


The tapered bore accepts a tapered sleeve or adaptor to create an interference fit for axial positioning and secure mounting.

What operational condition necessitates the specified internal clearance?


The greater-than-normal clearance accommodates thermal expansion and prevents premature contact at elevated operating temperatures.

What benefit does the open-end design provide during maintenance?


The open configuration allows Visual inspection and easier access for lubrication without disassembly.

How does the cage material affect service life under contamination?


The non-metallic cage can reduce particulate abrasion compared with some metallic cages but still requires appropriate sealing or filtration to limit contamination ingress.

What rotational limit should operators observe to avoid overstress?


The bearing should not be rotated above 9,500 rpm to prevent excessive centrifugal loads and heat generation.
