SKF Energy Efficient (E2) ball bearings and units
Minimize friction and maximize service life for optimized field performance
SKF E2 insert bearings
To meet the ever-increasing demand to reduce friction and energy use, SKF E2 insert bearings are characterized by a frictional moment that is at least 50% lower when compared to the same-sized standard insert bearing (diagram 1).
This substantial reduction of the frictional moment is achieved by a highly effective contact seal and applying a specially formulated, low-friction grease. Due to the reduced frictional moment, SKF E2 insert bearings run at up to 30 °C (55 °F) cooler than standard bearings (diagram 2), extending grease life and service life, where grease life is limiting (diagram 3).
SKF E2 ball bearing units - fully assembled, ready-to-mount
In addition to the energy savings offered by SKF E2 insert bearings, we have expanded our offering to meet more application needs for more customers.
We now provide fully assembled SKF E2 ball bearing units combining SKF E2 insert bearings and SKF composite housings.
Helping to reduce total cost of ownership, these lightweight, cost-effective and ready-to-mount units are particularly well suited for applications where high speeds, moderate loads, reliability and minimal maintenance are all key parameters. Available with different combinations of SKF E2 insert bearings and SKF composite housings, SKF E2 ball bearing units are relubrication-free.
They can be optimized for specific applications and conditions, helping customers reduce energy use and total cost of ownership.
