Description

The Ceramic  ABEC 5 bearings have ceramic balls and steel races.

Balls:
Silicon Nitride Ceramic Si3N4 balls are made from pure Silicon Nitride material with extreme high density from uniform compaction, the micro-structural development of this material during manufacturing is second to none. These high precision grade 5, Si3n4 pure ceramic balls are 5/1,000,000″ from exactly round in sphericity, 60% lighter weight, and 7 times harder than steel.
The balls are Grade 3, Silicon Nitride (Si3n4).  These are the roundest balls you can buy without a military license.

Seals:
We use Silicone LLB.
