✨What are the Benefits of choosing 32252-DF-A500-550 bearings?

  • DB (Back-to-Back): Provides high rigidity and anti-overturning properties, withstands bidirectional axial loads and tilting moments, suitable for cantilever shafts and machine tool spindles.
  • DF (Face-to-Face): Allows for some installation error compensation, withstands bidirectional axial loads, suitable for short shafts and easily deformable housings.
  • DT (Tandem): Significantly increases unidirectional axial load capacity, multiple sets of bearings jointly bear huge unidirectional thrust, suitable for heavy-duty thrust conditions.
  • The 32252-DF-A500-550 Tapered Roller Bearings adopts a Anti-tipping, fault-tolerant installation, ultra-high thrust design, Reference FAG technology, with dimensions an inner diameter of 260 mm, an outer diameter of 480 mm, a width of 274 mm, featuring Two (row) construction from 32200 DF series (322..-XL-DF-A500-550) (series), optimal operating temperature is generally -30 to 200 degrees Celsius. With grade precision of PN and ensure the equipment operates more stably , and the maximum speed can reach (Limit Speed Ratings (grease) rpm:473 Limit Speed Ratings (oil) rpm:1459)for applications Precision machinery and heavy equipment

🏭 What are the applications of the 32252-DF-A500-550 bearing?

  • DB (Back-to-Back): Used in machine tool spindles, cantilever gearboxes, and worm gears. Provides extremely high rigidity, effectively resisting tilting moments and ensuring precise shaft positioning.
  • DF (Face-to-Face): Used in short-shaft pumps, automotive differentials, and applications with relatively weak bearing housing rigidity. Can compensate for certain installation errors or shaft thermal deformation, reducing additional loads.
  • DT (Tandem): Used in heavy-duty rolling mills, large wind turbines, and the thrust end of marine propellers. Multiple sets of bearings share the enormous unidirectional axial force, significantly increasing load-bearing capacity.
