Cylindrical Roller Bearings for Crane Sheaves

NSK’s special design double-row full-complement cylindrical roller bearings are ideally designed for the rigor of crane sheave applications, contending with extreme loads and volatile operating conditions to deliver both optimal durability and performance.

Cylindrical Roller Bearings for Crane Sheaves

Design Features

  • Special design double row, full complement cylindrical roller bearing
  • Optimized, high-capacity internal design for heavy radial and axial loads
  • Phosphate inner and outer ring surface treatment for long-life corrosion resistance
  • With high performance contact seal for resistance to water or particle ingress
  • Grease is factory-packed into the bearing; replenishing with lithium grease is recommended
  • Also available in shielded and open bearing designs
  • Lubrication groove and holes in the inner and outer ring
  • Outer ring snap ring grooves in accordance to DIN 471; snap rings sold separately
  • For dimension series 50
  • With C-normal and C3 clearance
