6805 Thin Wall Deep Groove Ball Bearing – Precision & Durability for High-Performance Cycling

Ultra-Slim Design
– 25x37x7mm thin-walled construction reduces weight without sacrificing load capacity, ideal for space-constrained bike components like hubs and bottom brackets.
Premium Material
– High-carbon chromium steel races and balls ensure exceptional hardness (HRC 62+) and corrosion resistance, extending lifespan under heavy cycling stress.
Dual Protection
– Choose between ZZ (metal shield) for high-speed stability or 2RS (rubber seal) for superior dust/water resistance in wet or muddy conditions.
Precision Machining
– Mirror-polished grooves and ±0.001mm tolerance reduce friction, enabling smoother pedal strokes and lower energy loss.
Multi-Scene Use
– Perfect for road/MTB wheel hubs, e-bike motors, fitness equipment, and industrial gearboxes requiring compact, high-RPM bearings.
Bulk Discounts
– Global wholesale pricing with MOQ flexibility, backed by ISO 9001-certified manufacturing.
