NSK is a premium brand that can only be purchased through Authorized Distributors and Dealers. Selected for their reliability, knowledge and experience, NSK Distributors work diligently to meet our standards, and yours.

Managing inventories of critical spare bearings for our customers is standard practice, but proper handling of slewing rings transcends “on the shelf” measures. Improperly stored slewing rings can be impacted with corrosion damage, challenging their suitability for operation and presenting the prospect of extended downtime for costly bearing reconditioning.

NSK offers extended service to our customers to manage the condition of slewing rings stored at an NSK approved facility or stored at our customer’s facility. Services include:

The applications for slewing ring bearings in the metal-making process are decidedly challenging and unique. In Electric Arc Furnaces and Ladle Turrets, slewing rings must support massive loads with motion that is slow, restricted in range of rotation, and reliably repeatable. For an extremely long service life.

For slewing rings in operation, NSK Experts support our customers to manage bearing performance over the slewing ring’s operating life, as well as to manage the bearing life-end with predicted and scheduled replacement.

Our experienced bearings specialists are on hand to offer practical solutions to your problems and can assist with an on-site visit.

Slewing ring bearings from NSK are designed to transfer very high forces, supporting radial, axial and moment loads up to very large diameters. Lubrication features – designed to accommodate our customers’ systems – facilitate grease replenishment to reduce friction and wear with a clean supply of lubricant. Seal and shield options promote long-life reliability, an essential prerequisite in these applications.
