What Makes Sonic Bearings Different?

Feature
Sonic
Most Brands
Note
52100 chrome steel
Premium steel is made in Japan – most brands use steel from China
Heat treated steel
Strengthens the steel and increases wear resistance
Honed races and balls
Precision honed for fast and smooth performance
Deep groove raceways
Provides lateral stability for turns and stops
Stepped inner race
Stepped inner race keeps dirt out – protects bearing interior
Polymer cage
Polymer cages are lighter than brass or steel & dampen vibration
Non-contact rubber seal
Non-contact rubber seals keep dirt out without adding drag – fully serviceable
Synthetic gel lubricant
Most brands use a petroleum grease or oil
Premium quality
Taiwan-made – stringent manufacturing standards

What’s a stepped inner race?

Inline skate 608 bearings have 2 races – inner and outer. The outer race contacts the wheel hub and the inner race contacts the axle. To see the complete inner race, the shield or seal needs to be removed.

Our bearings feature an inner race with a step (think of a step on a flight of stairs). The inner step makes it very difficult for dirt and debris to reach the ball bearings. Clean bearings roll smoother, faster, and longer.

On bearings without a stepped inner race, dirt has a direct path to the ball bearings. The stepped inner race adds manufacturing costs but the result is a superior product.
