SKF Ball bearing 61904-2RS1 / 6904-2RS1

Performance class bearings SKF Explorer

By combining their expertise in bearing design, tribology, metallurgy, lubrication and manufacturing, SKF engineers have spent years maximizing the life of SKF bearings. The result is a new standard of excellence in both bearing performance and precision manufacturing processes, still unrivalled on the market today.

Bearings designed for optimum performance
Several features help optimize performance in the most challenging applications and conditions:
Optimized internal geometry reduces friction, wear and heat generation, while enabling SKF Explorer bearings to withstand higher axial and/or radial loads.
Optimized bearing elements address load distribution and reduce vibration levels.
Improved cages ensure better guidance of rolling elements and optimize lubricant effects.
Advanced surface finish reduces friction and improves hydrodynamic lubrication film formation.
ultra -pur steel with exceptionally pure materials gives SKF Explorer bearings unrivalled strength and longevity.
SKF Explorer bearings' unique heat treatment process delivers maximum hardness for superior service life, with high dimensional stability.
