SNN Modular Pillow Blocks | Lightweight, Rigid & Versatile Housings

Design Features

  • Highly rigid and lightweight split bearing housing design manufactured from cast iron grade 200
  • Modular design permits one housing to accommodate multiple bearing types and diameters
  • Support plain shafts with tapered bore bearings mounted with an adapter sleeve
  • Dimples on the housing surface facilitate additional holes for sensors, lubrication, mounting bolts or locating pins
  • 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
  • For plain shafts and tapered bore bearings mounted with an adapter sleeve
  • 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 20 to 140 mm, 3/4 to 5-1/2”

Operating Benefits

  • Split design facilitates simplified mounting and dismounting without dismantling the shaft or other components
  • Square shaped base and center marks facilitate alignment during installation
  • 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
