Product Description

22 Series -- Introduction

The 22 series bearings cover three core types: 22200/22300 spherical roller bearings and N2200 cylindrical roller bearings. Made of high-quality chrome steel (GCr15), they perform excellently in high-temperature, heavy-load and precision scenarios, complying with international standards and trusted globally.

The 22200 series spherical roller bearings have self-aligning capability to compensate coaxiality errors. With separable inner rings for easy maintenance, they balance rigidity and flexibility, suitable for general industrial machinery like conveyors and gearboxes.

Designed for heavy-duty use, the 22300 series features a wider inner ring and strong structure. It resists shock loads and operates stably in harsh environments, with low maintenance for large equipment like steel mill machinery.

The N2200 series cylindrical roller bearings prioritize high speed and precision. With compact structure and low friction, they ensure smooth rotation, ideal for precision equipment like motor spindles and CNC lathes.

22 Series -- Applications

With diverse advantages, 22 series bearings are widely used in multiple industries:

22200 Series: Conveyors, pumps, gearboxes, CNC accessories and agricultural equipment, ideal for general industrial use.
22300 Series: Vibrating screens, steel mill equipment, wind power parts and forging machinery, suitable for harsh heavy-duty conditions.
N2200 Series: Motor spindles, precision gearboxes, printing machinery and CNC lathes, meeting high-precision requirements.

Popular models (22205-22212, 22305-22310, N2205-N2210) cover diverse dimensions for customized needs.
