AB 25-1628-HP Wheel Bearings are rubber sealed bearings for additional protection from water and dirt. They feature precision high-speed bearings and double lip seals. Wheel bearings typically fail from water and dirt contamination. Rolling element bearings can be designed for radial loads, axial loads, or both. Load carrying capacity is proportional to the number of rollers and their diameter. High performance bearings pack high capacity into a small volume. They can be designed for a wide range of rotational speeds, including applications where speed varies quickly. In addition, bearing designers can incorporate self-aligning capabilities, which simplifies assembly into mechanisms and reduces costs.

why choose double roller bearing instead of ball bearing in wheel bearing?
All balls 25-1628-HP Double row roller bearing are used where loads tend to be very high speed performance, and a double row ball bearing wouldn’t provide the same life. In general, roller bearings will run faster, and carry heavier loads than ball bearings.
