SKF Self-Aligning 2 Row Ball Bearing 35 mm ID 80 mm OD 31 mm Race Width C3 Clearance Non-Metallic Cage Steel 2307 ETN9/C3

SKF 2307 ETN9/C3 is a high-performance self-aligning 2 row ball bearing engineered for demanding industrial use. It has a 35 mm inside diameter and 80 mm outside diameter with a race width of 31 mm, incorporating steel balls arranged in two rows supported by a non-metallic cage. This bearing is designed open-ended with a cylindrical bore to facilitate ease of installation and accommodate shaft misalignment of up to 3°.

The bearing features a C3 internal clearance which enables thermal expansion under operational loads, optimizing performance and durability. Its dynamic load rating of 39.7 kN allows it to sustain significant radial loads, while the static load rating of 11.2 kN provides resistance to heavy stationary loads. The limiting speed is rated at 12,000 rpm, suitable for applications requiring high rotational speeds without compromising stability.

This bearing is well-suited for use in conveyor drive systems where shaft deflections may occur, motor and gearbox assemblies in automation setups, electrical motors that demand high running speeds, and various mechanical actuators and linkages. Its robust construction and Italian manufacturing ensure exceptional quality and reliability in industrial, manufacturing, and maintenance scenarios.

Features two rows of steel balls and a non-metallic cage for smooth operation and longevity. Allows angular misalignment for flexible shaft positioning and reduced wear. High dynamic and static load ratings for sustained and heavy load conditions.

C3 internal clearance ensures thermal tolerance during operation. Open design facilitates easy maintenance and inspection. Ideal for rotary bearing applications in industrial, HVAC, and manufacturing systems. Manufactured to strict quality standards in Italy.
