NACHI 240 Series Spherical Roller Bearings (Cylindrical, K Bore)

NACHI 240 Series Spherical Roller Bearings (Cylindrical, K Bore)

NACHI 240 series double-row spherical roller bearings, bore 120 to 800 mm, with cylindrical bore or tapered bore (suffix K = 1:12 taper, K30 = 1:30 taper).

Key features

  • Self-aligning design for applications where misalignment can arise from mounting errors or shaft deflection
  • Maximum permissible misalignment of about 2 degrees under general service conditions
  • High radial load capacity with axial load capacity in both directions
  • Outer rings are often made with lubrication holes and groove (W33) for feeding lubricant
  • Each size listed with cylindrical bore and tapered bore designation (K or K30)
