ABEC 5 angular contact bearings with 20 mm internal diameter, 32 mm external diameter, 7 mm thickness and light-contact double-lip seals, creating a labyrinth seal.
In standard radial bearings, only 3 or 4 balls come into contact with the load at any one time. In angular contact (A/C) bearings, ALL the balls are in contact, spreading the force over a larger area to reduce friction and minimise wear.
