2202 / 2202-2RS Self-Aligning Ball Bearing | Wide Double Row Sealed And Open Bearings

The 2202 self-aligning ball bearing is a wide-body double-row radial bearing upgraded from the standard 1200 series, available inopen type 2202 and double rubber sealed 2202-2RS versions. Featuring a spherical outer raceway for automatic shaft alignment, this bearing efficiently compensates for shaft deflection, assembly misalignment and operational vibration. It supports heavy radial loads and slight bidirectional axial loads, delivering stable medium and high-speed operation. The 2202 series is widely recognized for high durability and versatile adaptability for general and harsh industrial working conditions.

2202 And 2202-2RS Core Advantages

Compared with standard narrow self-aligning bearings, the 2202 series adopts a widened internal structure with larger steel ball contact area, providing higher load capacity and better structural stability. The open 2202 model allows easy lubrication and low maintenance for clean indoor environments. The upgraded 2202-2RS double sealed version features rubber contact seals on both sides, effectively blocking dust, moisture and debris, preventing grease leakage and internal contamination. Both versions offer excellent self-aligning performance, eliminating abnormal noise, jamming and premature wear caused by shaft offset, ideal for long-cycle continuous operation.

2202 Bearing Material Types And Industrial Applications

Chrome Bearing Steel: Standard industrial bearing material with high hardness, outstanding wear resistance and fatigue resistance. It maintains stable precision under long-term heavy-load and medium-speed operation with high cost performance. Suitable for industrial fans, conveyor machinery, textile equipment, general automation and conventional light industrial transmission systems.

304 Stainless Steel: Excellent anti-rust and anti-oxidation properties, adapting to humid, dusty and open working environments. It ensures stable low and medium-load operation, serving as an economical anti-corrosion option for light industrial machinery, civilian automation and general indoor precision equipment.

420 Stainless Steel: Balanced hardness and mechanical toughness with mild chemical corrosion resistance. It resists frequent start-stop wear and weak medium erosion, retaining accurate self-aligning performance. Widely used in precision instruments, optical devices and portable electromechanical equipment.

440C Stainless Steel: Ultra-high hardness and superior abrasion resistance, perfect for damp workshops and moderately corrosive environments. It effectively avoids bearing aging, wear and jamming, ideal for automated production lines, light chemical machinery and precision heavy-duty transmission assemblies.

316 Stainless Steel: Premium corrosion-resistant material with excellent salt spray, acid and alkali resistance. It operates reliably in harsh corrosive and high-humidity scenarios, applicable for food sanitary machinery, marine auxiliary equipment, chemical instruments and sterile industrial facilities.

Features And Industry Application Scenarios

The 2202 and 2202-2RS wide self-aligning ball bearings feature enhanced heavy-load capacity, reliable misalignment compensation, low-vibration operation and multi-material customization. The 2202-2RS sealed variant is specially designed for dusty, humid and poorly protected working conditions, greatly extending service life and reducing maintenance costs. These bearings are widely applied in industrial automation, light manufacturing, ventilation and conveying systems, food processing, chemical and marine equipment, providing cost-effective and durable radial bearing solutions for various medium-speed mechanical systems.
