Reduce Downtime with Reliable 2221M Self Aligning Ball Bearing

Equipment failure due to bearing issues costs manufacturers thousands in lost production each year. Misalignment, premature wear, and inconsistent quality from uncertified suppliers often lead to unexpected shutdowns. Many buyers struggle with minimum order quantities that force overstocking or long lead times that delay repairs.

Engineered for Industrial Machinery Performance

Our 2221M Self Aligning Ball Bearing addresses these challenges with precision engineering and flexible supply. As an integrated manufacturer with ISO9001 and ISO14001 certifications, we ensure each bearing meets P0-P4 precision standards and Z2-Z4 noise grades. The double row steel cage design provides stability for industrial machinery, while our 1-piece MOQ and 10-15 day delivery time support both scheduled maintenance and emergency repairs.

Optimal Performance in Demanding Conditions

This double row bearing excels in applications with moderate radial loads and minor shaft misalignment, common in machine tools and agricultural equipment. Its 60-degree contact angle enhances load distribution, while the unseparated design simplifies installation. Whether operating in dusty factory environments or outdoor agricultural settings, the bearing steel construction ensures durability under continuous use.

Technical Features That Matter

The 2221M’s precision rating directly impacts operational efficiency—P0 for general industrial use, P5 for high-speed applications, and P4 for precision machinery. Clearance options (C0, C3, C4) allow customization for thermal expansion and preload requirements. The choice between steel and brass cages offers flexibility: steel cages provide cost-effective strength for standard operations, while brass cages reduce friction in high-speed scenarios. At 95×170×32 mm, this bearing fits common industrial gearbox and conveyor configurations.

Why Quality Bearings Lower Total Costs

Choosing uncertified bearings may save upfront costs but often leads to higher expenses later. Poor quality components typically fail within 30-50% of the expected lifespan, requiring repeated replacements and unplanned downtime. Our bearings, backed by a 12-month global warranty, reduce these risks. Each unit undergoes rigorous QC testing, from raw material inspection to final dimensional checks, ensuring consistent performance that minimizes maintenance costs over time.
