5215-2NS - NACHI

The Nachi 5215-2NS double-row, deep-groove, angular contact ball bearing is designed to bear extremely heavy loads and resist deformation pressure. It is also meant to handle both radial and axial loads simultaneously. It has a basic, static load-bearing capacity of 85,500 Newtons and a basic, dynamic load-bearing capacity 96,000 Newtons. When lubricated with grease, it can function at a maximum rotational speed of 3,400 revolutions per minute. When lubricated with oil, the maximum rotational speed goes up to 4,700 revolutions per minute.

The bearing also has two non-contact rubber seals, giving it an excellent ability to keep out both dust and water. The seals also make it particularly precise at low speeds though grease may sometimes leak from the bearing at high temperatures. It is generally functional at temperatures between -25 and 100 degrees Celsius.
