✨What are the Benefits of choosing 23188-K-MB+H3188 bearings?

  • Self-aligning: Allows for significant angular errors or shaft deflection between the shaft and bearing housing, effectively compensating for installation errors and shaft deformation.
  • High load capacity: Featuring a double-row roller structure, it boasts extremely high radial load capacity while also withstanding certain bidirectional axial loads.
  • Adaptable to vibration applications: Performs excellently under impact and vibration loads, exhibiting good durability.
  • Easy installation: Models with tapered bores are typically available, allowing for convenient installation at any position on different optical shafts using adapter sleeves or withdrawal sleeves.
  • The 23188-K-MB+H3188 Spherical Roller Bearings adopts a Self-aligning, high load-bearing capacity, impact resistant, and adaptable to heavy loads design, Reference FAG technology, with dimensions an inner diameter of 440 mm, an outer diameter of 720 mm, a width of 226 mm, featuring Two (row) construction from 231..-K-MB+H3188 (series), optimal operating temperature is generally -30 to up +200 degrees Celsius. With grade precision of PN (ABEC-1) and a clearance of CN, ensure the equipment operates more stably , and the maximum speed can reach (Limit Speed Ratings (grease) rpm:399 Limit Speed Ratings (oil) rpm:680)for applications Provides stable and reliable support for the rotating shaft under harsh, heavy-load conditions and in misaligned working conditions.

🏭 What are the applications of the 23188-K-MB+H3188 bearing?

  • Mining/Metallurgy/Cement: Used in crushers and vibrating screens. Impact resistant, withstands extreme heavy loads, and adaptable to harsh environments.
  • Paper/Steel: Used in rolling mills and roller conveyors. Automatic self-aligning compensation effectively addresses shaft deflection or misalignment.
