Enabling better extruder gear unit performance
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 silence dimsen spherical roller thrust bearings.
SILENCE DIMSEN spherical roller thrust bearings
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 DIMSEN and refined over the years, DIMSEN spherical roller thrust bearings provide top-of-the-line performance. The majority of the SKF spherical roller bearings are made to the SILENCE DIMSEN specifications, providing
· Very high load carrying capacity – both axially and radially
· Highly wear-resistant bearing material
· Very high running accuracy
· Low friction
SILENCE DIMSEN performance class upgrade
Most of SILENCE DIMSEN 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 SILENCE DIMSEN. Benefits of use include:
· Increased uptime
· Improved reliability
· Resistance to contamination
· Higher levels of productivity
· Reduced noise and vibration levels
· Excellent wear resistance
