6202ZZ -Koyo Bearings

The 6202ZZ bearings, classified as deep groove ball bearings, are meticulously engineered components designed to meet the demands of various applications requiring efficient radial and axial load support. Featuring an inner diameter (d) of 15 mm, an outer diameter (D) of 35 mm, and a width (B) of 11 mm, these bearings offer compact dimensions ideal for space-constrained installations. Their impressive load-bearing capabilities, with a basic dynamic load rating (Cr) of 9.55 kN, ensure reliable performance across diverse operating conditions. Additionally, with a basic static load rating (C0r) of 3.75 kN and a fatigue load limit (Cu) of 0.290 kN, they exhibit robustness and durability in demanding environments. Operating at a factor (f₀) of 13.2, these bearings are optimized for efficiency, coupled with a limiting speed of 20,000 min⁻¹ under grease lubrication, ensuring smooth operation and minimal friction. Meticulously specified mounting dimensions, including minimum inner ring diameter (da), maximum inner ring diameter (da max), maximum outer ring diameter (Da max), and maximum radial clearance (ra max), facilitate easy installation and alignment, contributing to overall system efficiency and longevity. Despite their robust construction, these bearings are lightweight, weighing only 0.045 kg each, minimizing inertia and reducing energy consumption, making them an ideal choice for applications where efficiency, reliability, and longevity are critical considerations.
