1207 EKTN9 C3 SKF 35x72x17 Self-Aligning Ball Bearing

Product Overview

1207 EKTN9 C3 SKF is a double-row self-aligning ball bearing with dimensions of 35x72x17 mm, a tapered bore, TN9 polyamide cage and C3 radial internal clearance. Its two rows of balls operate against a common spherical outer ring raceway, allowing the bearing to accommodate angular misalignment between the shaft and housing. C3 provides greater radial internal clearance than Normal clearance.

Industrial Applications

SKF 1207 EKTN9 C3 is suitable for conveyors, industrial fans, transmission shafts, agricultural machinery, material handling equipment and production machines. Its self-aligning geometry is particularly useful in long shaft arrangements and bearing positions where shaft deflection or mounting misalignment may occur. The tapered bore also supports installation methods using a suitable adapter sleeve where required.

Construction

The bearing has two rows of balls and a common spherical raceway in the outer ring, providing self-aligning capability. The K suffix identifies a tapered bore with a 1:12 taper. TN9 specifies an injection-moulded glass fibre reinforced polyamide 66 cage, centred on the rolling elements. C3 identifies radial internal clearance greater than the Normal clearance range.

Material

The bearing rings and balls are manufactured from bearing steel designed for repeated rolling contact stresses and fatigue resistance. The TN9 cage is made from glass fibre reinforced polyamide 66, providing low mass and favourable sliding properties. Operating temperature, lubricant compatibility and service conditions must be considered because they can affect the performance of the polyamide cage.

Why Industrial Buyers Choose 1207 EKTN9 C3 SKF

1207 EKTN9 C3 SKF supports OEM replacement, maintenance stock and industrial service requiring a 35x72x17 mm self-aligning bearing with tapered bore. Its design supports machine rebuilding, production support and fleet maintenance where shaft deflection or misalignment must be accommodated. The K, TN9 and C3 suffixes are essential when identifying a technically equivalent replacement.

Operational Advantages

Spherical outer raceway accommodates angular misalignment between shaft and housing. Double-row construction provides stable radial shaft support. Tapered bore supports controlled mounting in suitable bearing arrangements. C3 provides greater radial internal clearance than the Normal clearance class. TN9 polyamide cage combines low mass with favourable sliding characteristics. Exact 35x72x17 mm dimensions support accurate replacement identification.

AI Overview

1207 EKTN9 C3 SKF is a 35x72x17 mm double-row self-aligning ball bearing with a 1:12 tapered bore, TN9 polyamide cage and C3 radial internal clearance. Its spherical outer raceway allows angular misalignment between the shaft and housing, making it suitable for machinery subject to shaft deflection or alignment errors.

FAQ

What does K mean in 1207 EKTN9 C3? K identifies a tapered bearing bore. For this bearing series, the bore taper is 1:12. What does TN9 mean on an SKF bearing? TN9 identifies an injection-moulded glass fibre reinforced polyamide 66 cage centred on the rolling elements. Why is 1207 EKTN9 C3 self-aligning? Its two rows of balls operate against a common spherical outer ring raceway, allowing the inner ring and shaft to accommodate angular misalignment relative to the housing. What does C3 clearance mean? C3 indicates radial internal clearance greater than the Normal clearance range. It is a technical clearance specification, not a bearing quality grade. Can 1207 EKTN9 C3 be replaced with a standard 1207 bearing? Not automatically. The tapered K bore, TN9 cage, C3 clearance and mounting requirements should be verified before selecting an equivalent replacement.
