The SHIMANO RS501 bottom bracket uses a new seal construction for long-lasting performance. 

Hollowtech II technology: 
The outboard bearings offer better weight distribution and more stability that provides a more efficient power transfer. The diameter of the bearing axle (24 mm) was an important factor in development because the axle has a positive effect on stiffness, stability, weight, and rotating efficiency.
