The Bronson Speed Co. G3 skateboard bearings are engineered to roll farther and resist impacts better than any other bearing on the market. Skateboard bearings have essentially stayed the same for the last 30 years, so Bronson Speed Co. thought it was about time to reinvent this overlooked component. More than two years of testing and development were put into the G3, chances are you won't be disappointed.

ABEC 7 - The ABEC scale is essentially a measurement of bearing tolerance for high precision bearings as dictated by the Annular Bearing Engineering Committee (ABEC). The scale runs from ABEC 1 through ABEC 9 using odd integers only. Essentially, the higher up on the scale a bearing is rated the tighter the tolerance is.
Tighter bearing tolerance means that the bearing moves with less resistance at high speeds, giving you a bit more roll for your push. In general most ABEC 3 or ABEC 5 bearings have steel races (shell of the bearing) with hardened steel ball bearings, and most ABEC 7 or ABEC 9 bearings feature steel races with super hard (much harder than steel) ceramic or titanium bearings.
Deep Groove Raceways - Balls sit and roll deeper in the raceway channels than weaker shallow groove designs.
Reduces axial and angular side impact damage and breakage, surfaces stay smooth and fast.
Straight Edge Frictionless Shields - Non-contact rubber shields fit deep in the inner race edge- reduces oil leak and dirt & moisture intrusion.
Free spinning, durable, pop off resistant shields, serviceable, remove-able, easy to clean and re-install.
Micro-Groove Raceway Surfaces - Self-smoothing microscopic linear grooved raceway surfaces improve bearing lubrication and spin.
The micro grooves increase spin by eliminating the standing wave of lubricant just in front of the rolling ball.
Max Impact Cage Design - Strong, non-distortion glass filled nylon cage keep the balls precision spaced and oil circulating.
Ball cage socket surfaces engineered to hold oil and provide continuous ball lubrication.
High Speed Ceramic Oil - Oil is blended with nano-ceramic compounds for anti-wear protection for longer lasting bearings and improved speed.
Light and smooth- with additives that resist rust, moisture, corrosion and oxidation for prolonged oil life.
Hand Inspected for Quality - 100% hand inspected twice and micro-polished and ultrasonic solvent washed 3X prior to final lubrication.
Packaged in nitrogen filled shrink-wrap - reduces metal and oil oxidation until ready to be ridden.
Balls Out Technology - For optimum high speed performance install bearing with the designated balls-out/cage-in orientation (black pinstriped shields facing outside of wheel.) Results in a go fast, stay fast bearing that spins longer by reducing shield and cage contact on impact.
