CHARACTERISTICS OF WINKEL VULKOLLAN AND POLYAMIDE BEARING : 



Since more than 39 years WINKEL GmbH are working in the field of linear system and material handling. They are market leader in the field of heavy load linear systems and have delivered thousands of handling systems.

Winkel Offer two types of Bearings: Vulkollan Bearing and Polyamide Bearings.

Vulkollan Bearing:

When any System requires Speed + Silent Operation Vulkollan bearing is Preferred. The max speed of the bearing is 6 m/s whereas Std bearing has max peed of 1.5 m/s

Material Specification: 

  • Outer rings are made from case-hardened steel UNI 16 CrNi 4 hardened at 62+2HRC 
  • Inner rings are made from bearing steel En 31-SAE 52100 hardened at 62-2 HRC 
  • Cylindrical rollers have flat ground heads, made from En 31-SAE 52100 steel hardened at 59 – 64 HRC. 

 Advantages:  

  • Excellent resistance to mechanical wear.  
  • High rebound resilience, even in hard grades.  
  • Good tear propagation resistance.  
  • Low compression set.  
  • Good resistance to mineral oils, greases, petrol and a wide range of solvents.  
  • Best dynamic performance of all urethanes. 

Polyamide Bearings:

When any system requires Speed + Force in operation Polyamide bearing is preferred. The max speed of the bearing is 6 m/s whereas standard bearing has max speed of 1.5 m/s.  

It has higher load carrying capacity than Vulkollan Bearing. 




Material Specification:  

  • Outer rings are made from case-hardened steel UNI 16 CrNi 4 hardened at 62+2HRC 
  • Inner rings are made from bearing steel En 31-SAE 52100 hardened at 62-2 HRC 
  • Cylindrical rollers have flat ground heads, made from En 31-SAE 52100 steel hardened at 59 – 64 HRC

Advantages: 

  • High wear resistance.  
  • High thermal stability.  
  • Very good strength and hardness.  
  • High mechanical damping characteristics.  
  • Good sliding properties. 
  • Good chemical resistance

  Electric Actuators : Green solution against pneumatic and hydraulic actuators .         As the industrial world becomes increasingly connected, the designer’s need for intelligent components that can communicate with each other and operate without the need for manual interaction is growing.   Hydraulic- Pneumatic Actuators :    Pneumatic linear actuators consist of a piston inside a hollow cylinder. Pressure from an external compressor or manual pump moves the piston inside the cylinder. As pressure increases, the cylinder moves along the axis of the piston, creating a linear force. The piston returns to its original position by either a spring-back force or fluid being supplied to the other side of the piston.   Accuracy Requires expensive position sensing and precise electrohydraulic valving to implement. Has tendency to creep.   Hydraulic linear actuators operate similarly to pneumatic actuators, but an incompressible liquid...
