Slewing bearings are specially designed to handle heavier loads while enabling rotational motion and are absolutely critical components in the field of heavy machinery. Slewing bearings consist of an inner and outer ring, one of which usually contains a gear. Together with the connecting holes on the two rings, they enable optimized power transmission through simple and quick connection between adjacent machine parts.

Boost productivity and improve operator comfort

Selecting the right slewing bearing can be a challenge, especially when technical, reliability or economic requirements are stringent.The mining industry’s demanding conditions and heavy loads present tough challenges for excavators, bucket wheel excavators and stacker/reclaimers. Slewing bearing solutions are critical to the performance and reliability of these applications.

Maintenance and service tips

Maximizing the performance and life of your slewing bearing requires regular maintenance, including seal checks, addressing any misalignment as soon as possible, and protecting the bearing from harmful contaminants and corrosion. Doing so can prevent problems and reduce downtime. NSAR is pleased to offer you a wide range of products, from small single-row ball slewing bearings for light applications to large three-roller slewing bearings for demanding heavy applications, as well as gear bearings for all applications in between. Our slewing rings are designed for durability and stability.
