Double Row 2304-TN9 2304-M 2304-2RS-TVH 2304-2RS-TN 2305 2304 Self-aligning Ball Bearing

The 2304 is a double-row self-aligning ball bearing engineered for automatic compensation of shaft misalignment and stable radial load bearing, widely used in textile machinery, ventilation equipment, agricultural machinery, and light industrial transmission systems. Model breakdown: "23" denotes the double-row self-aligning ball bearing series (optimized for adapting to slight shaft deflection or housing misalignment); "04" is the size code (standard dimension matching—inner diameter calculated by "04×5=20mm", conforming to ISO self-aligning ball bearing size norms). Its spherical outer ring raceway design enables automatic adjustment of rotational concentricity, making it ideal for scenarios with unavoidable shaft/housing misalignment (e.g., long-shaft equipment, vibrating light-duty machines).

Interchangeability & Applications

• Textile Machinery: Roller shafts of spinning frames, drawing machines—compensates for slight shaft deflection during long-term operation.
• Ventilation & HVAC Equipment: Impeller shafts of industrial fans, air conditioner blowers—handles radial loads while adapting to motor-housing misalignment.
• Agricultural Machinery: Transmission shafts of small harvesters, irrigation pump shafts—balances dust resistance (with optional seals) and misalignment compensation.
• Light Industrial Equipment: Printing machine roller shafts, packaging machine conveyor rollers—ensures smooth rotation at speeds up to 9,400 rpm under general radial loads.
