SAF Split Pillow Blocks

NSK’s SAF series pillow blocks are designed to ensure optimal bearing performance and service life in a wide range of industrial applications. They accommodate heavy loads and misalignment, possessing the engineered strength to also withstand mechanical shock, corrosion, contamination and extreme temperatures.

SAF Split Pillow Blocks | Durable Housings for Heavy-Duty Applications

Design Features

  • Split bearing housing design manufactured from cast iron (SAF), ductile iron (SAFD) or cast steel (SAFS)
  • Dimension series 500, 600 and 000K support plain shafts with tapered bore bearings mounted with an adapter sleeve
  • Dimension series 200 and 300 support stepped shafts with cylindrical bore bearings mounted on a cylindrical seat
  • Machined to accommodate bearings in locating and non-locating positions
  • For spherical roller bearings in normal to heavy load applications, self-aligning ball bearings in light load, high-speed applications
  • Equipped to facilitate grease re-lubrication and oil-bath lubrication
  • Contact and non-contact seal design options to suit a wide range of mechanical and environmental operating conditions
  • For shafts ranging from 1-7/16 to 10-1/2”

Operating Benefits

  • Split design facilitates simplified mounting and dismounting without dismantling the shaft or other components
  • Preserves optimum bearing lubrication and prevents ingress of contaminants
  • Resistant to corrosion, mechanical shock and resilient in extreme temperatures
  • High performance seal design options for severely contaminated environments

Fields of Application including

  • Concrete and cement
  • Conveyors and material handling
  • Fans and blowers
  • Mining and construction machinery
  • Paper making machinery
  • Steel making machinery
