SKF Explorer steel/steel plain bearings

Virtually maintenance-free and extremely robust

SKF Explorer spherical plain bearings

SKF Explorer steel/steel spherical plain bearings are initially lubricated and sealed to eliminate the need for relubrication in applications with low to moderate levels of contamination, such as those in off-highway applications. This generates significant savings by reducing maintenance costs and grease consumption. These virtually maintenance-free1) bearings also improve reliability by eliminating failures due to missed lubrication intervals and improper lubrication practices. All of this adds up to reduce the Total Cost of Ownership (TCO).

SKF Explorer steel/steel plain bearings have been optimized to provide field performance advantages. Combining improved corrosion resistance, heavy-duty sealing and a relubrication-free design with a steel/steel sliding combination makes SKF Explorer steel/steel plain bearings more robust than ever. Plus, extensive research and testing under extreme loads has resulted in increased dynamic load ratings for SKF Explorer steel/ steel plain bearings, an increase of 50% when compared to conventional steel/steel bearings.

  1. 1) Virtually maintenance-free means that the bearing should function as intended without being relubricated as long as the tribological system is not compromised. The term maintenance-free does not imply that these bearings should not be inspected as part of a regularly scheduled maintenance programme.
