Ultra-Precision 627 Miniature Bearing – Built for Performance & Versatility
Crafted with high-carbon chromium steel for superior hardness (HRC 62+) and corrosion resistance, ensuring extended durability under heavy loads. Precision-ground raceways and polished balls (G10 grade) minimize friction, delivering smooth rotation at up to 30,000 RPM—ideal for high-speed applications. Triple-sealed design (rubber shields on both sides) prevents dust/water ingress, perfect for outdoor gear like skateboards, bicycles, and electric scooters. 7mm inner diameter x 22mm outer x 7mm width—compact yet robust, engineered for tight spaces in DIY projects, RC cars, and industrial mini-motors. Direct factory pricing: Bulk orders available at unbeatable rates, backed by global logistics for fast wholesale fulfillment.
