HRB Harbin Thin Wall Deep Groove Ball Bearing 61806tn ZZ 2RZ – Precision Engineering for High-Performance Applications

Premium thin-wall design with 30mm inner diameter and 42mm outer diameter, optimized for space-constrained installations while maintaining load capacity. Precision-ground steel races and high-grade balls ensure smooth rotation and extended service life under radial loads.

Dual shielding (ZZ) and rubber seals (2RZ) options provide superior dust and moisture protection, ideal for harsh environments like industrial machinery, automotive components, and electric motors.

Ultra-slim 7mm thickness reduces weight without compromising durability, perfect for robotics, medical devices, and compact gearboxes. Heat-treated chrome steel construction resists wear and deformation under high-speed operation.

Globally sourced materials and ISO-certified manufacturing guarantee consistent quality. Bulk pricing available for OEMs and distributors – wholesale rates unlock unmatched value for volume buyers.

Friction-optimized design lowers energy consumption, making it a sustainable choice for precision applications requiring minimal maintenance. Backed by HRB"s reputation for reliability in bearing technology.

Note: Specify ZZ (metal shields) or 2RZ (rubber seals) when ordering to match your contamination protection needs.
