Differences Between ABEC-3, ABEC-5, and MAX Bearings
The ABEC standard (Annular Bearing Engineering Committee) defines the manufacturing precision of a bearing. The higher the number, the tighter the tolerances, which improves smoothness and efficiency. However, a higher ABEC rating does not always mean better durability for cycling applications.
The best balance between smoothness, durability, and price. Widely used on versatile bikes.
Ideal for:
All types of bikes
Hubs
Bottom brackets
More precise and smoother bearings, designed to optimize performance and efficiency.
Ideal for: Hubs, Bottom Brackets
SGM bearings feature a riveted cage that keeps the balls securely in place — far more effective than standard ball retainers.
These bearings are also available with a Black Coating surface treatment, which provides increased corrosion resistance and extends durability.
Specifically designed for MTB suspension pivots subjected to heavy loads and impacts. Unlike a standard bearing, the MAX design uses the maximum number of balls without an internal cage (“full complement”), increasing load capacity by 35–40% as well as overall durability.
Ideal for:
Enduro / DH
Suspension pivots (frames)
