✨What are the Benefits of choosing 3205A bearings?

  • Bidirectional Load Capacity: A single bearing can simultaneously withstand bidirectional axial and radial loads, eliminating the need for paired installation.
  • High Rigidity and Anti-Overturning: A large contact angle design effectively resists tilting moments, ensuring shaft system stability.
  • Compact Structure: Occupies minimal axial space, simplifying housing design and facilitating installation.
  • The 3205A Double row angular contact ball bearings adopts a withstand radial and bidirectional axial loads simultaneously, has a compact structure, and good rigidity design, Reference NTN technology, with dimensions an inner diameter of 25 mm, an outer diameter of 52 mm, a width of 20.6 mm, featuring 2 (row) construction from 32 series (32..A) (series), optimal operating temperature is generally -40 to 120 degrees Celsius. With grade precision of P0 (ABEC 1) and a clearance of CN, ensure the equipment operates more stably , and the maximum speed can reach (Limit Speed Ratings (grease) rpm:7238 Limit Speed Ratings (oil) rpm:9783)for applications Various industrial applications requiring moderate loads and speeds that can withstand bidirectional axial forces and have simplified designs.

🏭 What are the applications of the 3205A bearing?

  • Gearboxes/Reducers: Used in industrial gearboxes and planetary reducers. Withstands bidirectional composite loads, provides high rigidity support, and ensures smooth transmission.
  • Pumps/Compressors: Used in centrifugal pumps, screw pumps, and refrigeration compressors. Precise axial positioning, compact structure, and space-saving installation.
  • Agitators/Worm Gear Drives: Used in agitators, worm gear reducers, and machine tool indexing heads. Effectively resists tilting moments; a single bearing solves bidirectional axial positioning.
