SKF 2309 EKTN9/C3

SKF 2309 EKTN9/C3 Self-aligning Ball Bearing Description The SKF 2309 EKTN9/C3 is a high-performance self-aligning ball bearing designed to accommodate static and dynamic misalignment. The bearing has two rows of balls and a common sphered raceway in the outer ring, which allows for angular misalignment of the shaft relative to the housing. This item is new in its original packaging (New Old Stock).

What is the significance of the ‘K’ and ‘C3’ suffixes in the 2309 EKTN9/C3 designation? The ‘K’ indicates that the bearing has a tapered bore (taper 1:12), which allows it to be mounted on a tapered shaft or on a cylindrical shaft using an adapter sleeve. The ‘C3’ suffix signifies that the bearing has a radial internal clearance that is greater than ‘Normal’, which is necessary for applications with temperature differences between the inner and outer rings or for high-speed operation. Question? What is the proper mounting procedure for a bearing with a tapered bore like this one? Mounting a tapered bore bearing involves driving it up the tapered seat. The correct fit is achieved by controlling either the axial drive-up distance or by measuring the reduction in radial internal clearance. Using an adapter or withdrawal sleeve is common. It is crucial to follow SKF’s guidelines and use proper tools to avoid damaging the bearing. Question? Is the polyamide cage (TN9) suitable for all operating environments? The glass fibre reinforced polyamide 6,6 cage (TN9) offers an excellent combination of strength and elasticity. However, its suitability can be affected by temperature and certain chemicals. It is generally stable up to 120 deg C (250 deg F). For applications involving specific synthetic oils, greases with synthetic base oils, or aggressive coolants, it is recommended to check for chemical compatibility with polyamide.
