SKF Explorer spherical roller thrust bearings

Enabling better extruder gear unit performance

SKF Exporer spherical roller thrust bearing
Extruder gear units operate in very tough conditions. Demands on key positions include heavy torque to the screw, very heavy and fluctuating axial loads created in the screw and sudden shock loads due to imperfect melting conditions in the barrel.

The result? The spherical roller thrust bearing at the end of the barrel is highly vulnerable. The SKF solution? High performance SKF Explorer spherical roller thrust bearings.

SKF Explorer spherical roller thrust bearings

Spherical roller thrust bearing - cut open
Spherical roller thrust bearings are characterized by their self-aligning ability and very high load-carrying capacity. They are designed to accommodate axial load or combined axial and radial loads.

Invented by SKF and refined over the years, SKF spherical roller thrust bearings provide top-of-the-line performance. The majority of the SKF spherical roller bearings are made to the SKF Explorer specifications, providing
  • Very high load carrying capacity – both axially and radially
  • Highly wear-resistant bearing material
  • Very high running accuracy
  • Low friction

SKF Explorer performance class upgrade

Most of SKF Explorer spherical roller thrust bearings have been upgraded to the new SKF Explorer performance class specifications, featuring a combination of high-quality steel and an improved heat treatment process. The result: a superior balance between hardness and toughness, enabling up to twice the service life as the original SKF Explorer. Benefits of use include:
  • Increased uptime
  • Improved reliability
  • Resistance to contamination
  • Higher levels of productivity
  • Reduced noise and vibration levels
  • Excellent wear resistance
