21315 EK Double Row Spherical Roller Bearing

21315 EK Double Row Spherical Roller Bearing

The 21315 EK is a double-row spherical roller bearing with a 75mm bore and 160mm outer diameter, crafted from sturdy chrome steel. It manages combined loads up to 65419 lbf and operates smoothly at speeds up to 5600 RPM.

Its open design allows for easy lubrication, while the steel cage ensures durability. The bearing performs reliably in temperatures ranging from -30°C to 200°C.

With a tapered bore (1:12 ratio), it fits securely on shafts, reducing slippage. The lubrication groove and holes make maintenance straightforward.

Ideal for heavy-duty applications like industrial gearboxes or mining equipment, where high radial and axial loads are common. Compliant with RoHS and REACH standards, it’s a dependable choice for replacements, interchangeable with SKF models. Weighing 3.75kg, it balances strength and practicality.
