Bearings with solid lubricants

Ložiska s tuhým mazivem
Thanks to advanced development and technologies, a new type of maintenance-free bearing has been developed. These bearings do not need to be lubricated because they are filled with a solid, porous resin that is impregnated with lubricating oil. As the bearing moves, this lubricant is continuously released through capillaries to ensure its smooth running.
 
Since the oil is maintained in a solid material, there is a minimum probability of leakage from the bearing, prolonging the service life of the bearings in applications where there is high centrifugal force or vibration. A space filled with a lubricated material also prevents dirt from entering the bearing, but does not replace seals.
These bearings are welcomed in clean plants, especially in the food industry and in operations where it would not be possible to lubricate. Stainless steel bearings with this type of lubricant are a highly resistant option for operation in wet, water or polluted environments and achieve more than twice the service life of conventional bearings. They are used for conveyors, cranes and many other industries.
Certain manufacturers use different brands for these bearings:
 

NSK – Solid lube

  • Eight grease types: Standard (designation 1), for low temperature (8), for low speed and high load (4), two types for high temperatures (5 and 6), for high speed (A) and two types of food grease (B and 7).
  • For all types of bearings.
 

NSK – Molded-Oil

  • Two grease types: Common use or high-speed.
  • Stainless steel version.
  • Special design for highly contaminated environments, water and for food applications.
  • For ball bearings, spherical roller bearings and tapered roller bearings.
  • For bearing units with stainless steel bearings with solid lubricants.
 

IKO – Capilube

  • Lubricating oil is contained in a porous synthetic resin.
  • Can be used for all types of needle bearings.
  • For temperatures from -15 to +80° C.
 

NTN solid grease

  • Two types of solid grease bearings: LP03 for general use and LP09 for the food industry.
  • For all types of bearings and for bearing units.
