The 3204.ZZ.NR RICH, also known as 5204 ZZ NR, is a high-quality double row angular-contact ball bearing, meticulously manufactured by RICH in China. This precision-engineered bearing is designed to support combined loads, meaning it can handle both radial and axial forces simultaneously. With dimensions of 20 mm bore, 47 mm outer diameter, and 20.6 mm width, it offers a compact yet durable solution for a wide range of demanding applications.
This RICH bearing incorporates a robust steel cage that ensures optimal ball separation and reliable operation even under varying load conditions. Featuring a CN (normal) clearance, it is ideal for standard operating environments. Its double-row design enables axial load handling in both directions, making it especially effective in setups with reversing or variable axial forces.
The bearing is equipped with double-sided non-contact shields (ZZ), offering protection against dust and larger debris while enabling higher rotational speeds than sealed variants. The NR designation indicates a groove and snap ring on the outer ring, allowing for secure and precise axial positioning within a housing and simplifying installation and maintenance.
Weighing just 0.16 kg, this compact yet high-performing bearing is suitable for a variety of systems that demand precision, cleanliness, and ease of mounting—such as electric motors, conveyors, gearboxes, and industrial machinery.
