01. Extended Wide Thin-Wall Profile

Featuring an optimized 10×19×7 mm layout, this design provides a wider tracking footprint than standard 6800 bearings. This extra width delivers greater radial stiffness and handling capacity for light combined loads without increasing the overall housing diameter.

02. Frictionless Non-Contact Shielding

Dual pressed-steel shields (ZZ) provide robust protection against particulate ingress without inducing mechanical drag. This zero-contact method keeps operational temperatures low and prevents energy loss, maximizing battery runtimes in portable electronic devices.

03. Industrial-Grade Chrome Steel (GCr15)

Forged from ultra-clean, vacuum-degassed GCr15 high-carbon chrome steel, both the rings and balls undergo precise thermal treatments to ensure exceptional Rockwell hardness and wear resistance. Pre-packed with premium grease, these bearings offer silent, smooth operation right out of the box.
