How to choose a good bearing for your skateboard?

(1) Is ABEC the only thing that you need to know to decide how good a Bearing is for skateboard?
It Helps, and is a good general reference, but it is not the only consideration that you should know. Some of the BEST Bearings have a lower ABEC rating than their performance in skateboard would indicate. This is primarily due to the design of the Race Curvature allowing Axial Thrust.

(2) What makes a good Roller Skateboard Bearing?

A. Free Rolling with minimal Radial Play (which reduces the ball to ball load transfer).
B. Plenty of Axial Play or Axial Thrust. This is what allows a Skateboard Bearing to work well. The tighter Axial tolerances of a higher ABEC Rating is not always what is needed for Roller Skating.
C. How much noise the Bearing makes is not of supreme importance. Bearing Noise is more often an indication of proper lubrication, or lack there of.

(3)What is the Cage and what Type of Cage is best for Skateboard Bearing?

The cage, also referred to as the retainer or separator, is the component that separates and positions the balls at approximately equal intervals around the bearing raceway. Proper selection of a bearing cage is critical for meeting the load, speed and temperature requirements for skateboard bearings. For Roller Skating, Brass or Stainless Steel Retainers provide the most roll, but also require the most care in cleaning and especially maintaining the lubrication properly so as to NOT let dry metal run against dry metal. A Snap Retainer of Synthetic or GlassFibre Reinforced Synthetic does not provide quite as much roll (but fairly close), and are much easier to maintain the cleaning and lubrication.
Roll-Line has introduced the Carbon impregnated Synthetic Snap Retainer. The Carbon J Snap Retainer provides some protection against under Lubricating the Skateboard Bearing and increases the ROLL.

(4)Are Shields and Seals Needed or Useful for Roller Skateboard Bearings?
Shields and seals are used in ball bearings to retain lubricants and prevent particulate contamination from reaching the critical surfaces. Shields are popular for most applications; seals are used where minimal clearance to light contact is required. Seals offer greater deterrence to particulate contamination, but increase torque and limit operating speed. The shields also make a little harder to clean as well. The suggestion is to just clean and lubricate the Skateboard Bearings a little more often and especially before any big competition or event.

(5)How to Handle and Work with Skateboard Bearings
Ball bearings are very precise mechanisms that, in many cases, have geometrical tolerances measured in millionths of an inch. When handling, inspecting or mounting bearings, one should treat them as precision instruments. The user's poor handling techniques cause most bearing failures.
Foreign particulate matter entering a bearing also shortens its life, and provides one or all of the following unsatisfactory operating conditions:
Increased Noise
