SKF Energy Efficient (E2) Y-bearings and units

Minimize friction and maximize service life for optimized field performance

SKF E2 Y-bearing units

SKF E2 Y-bearings

To meet the ever-increasing demand to reduce friction and energy use, SKF E2 Y-bearings are characterized by a frictional moment that is at least 50% lower when compared to the same-sized standard Y-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 Y-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 Y-bearing units - fully assembled, ready-to-mount

In addition to the energy savings offered by SKF E2 Y-bearings, we have expanded our offering to meet more application needs for more customers.

We now provide fully assembled SKF E2 Y-bearing units combining SKF E2 Y-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 Y-bearings and SKF composite housings, SKF E2 Y-bearing units are relubrication-free.

They can be optimized for specific applications and conditions, helping customers reduce energy use and total cost of ownership.
