Double Row Stainless Steel S1305 1305 Self-aligning Ball Bearing Without Seal bearings

The 1305 is a standard double-row self-aligning ball bearing engineered to accommodate radial loads while compensating for slight shaft-housing misalignment (angular deviations up to 2°–3°), widely used in general industrial machinery, textile equipment, and low-to-medium load rotating components. Model breakdown: "13" denotes the self-aligning ball bearing light-wide series (optimized for balanced load capacity and installation flexibility); "05" is the inner diameter code (calculated as code × 5, corresponding to standard inner diameter dimensions). Its self-aligning feature eliminates the need for strict shaft-housing coaxiality, making it ideal for scenarios with inevitable installation errors or shaft deflection.

Interchangeability & Applications

• Interchangeability: Compatible with standard 1305 self-aligning ball bearings from major brands (matching 25×62×17mm dimensions and double-row structure). Verify cage material (typically stamped steel for standard variants) and load rating to ensure consistency with application requirements.
• Main Applications:
  • Textile machinery (spinning frame and weaving machine shafts, compensates for slight shaft deflection during operation).
  • Industrial fans (centrifugal fan impeller shafts, adapts to installation misalignment between motor and fan).
  • Centrifugal pumps (water pump shafts, handles radial loads while tolerating minor coaxiality errors).
  • Agricultural machinery (small tractor auxiliary components, such as conveyor and mixer shafts, withstands variable working conditions).
