Self Aligning Ball Bearings 2309-2RSTN

Self Aligning Ball Bearings 2309-2RSTN

The 2309-2RSTN is a self-aligning ball bearing with a 45mm bore and 100mm outer diameter, crafted from sturdy chrome steel. It manages radial loads up to 8775 lbf and operates smoothly at speeds up to 4300 RPM.

Its double-row design and sealed construction help it stay aligned and protected from dust, while the nylon cage reduces friction. The bearing works in temperatures from -30°C to 110°C.

This model is interchangeable with SKF bearings, offering a reliable alternative for replacements. It’s well-suited for machinery where misalignment or heavy radial loads are expected, like conveyor systems or agricultural equipment.

Weighing 1.3kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards, it’s a safe choice for various industrial applications.
