MAX bearings are designed without retainers and have 40% more balls than standard ABEC 3 or 5 bearings. This design allows them to carry a higher load and makes them ideal for frame pivots. They are also packed with CRC Marine Grease, which is water-resistant and will not wash out or break down when wet. This ensures that your frame bearings will last even longer.
