OKS Speciality lubricants for Rolling bearing lubrication

Product catalog summary

Introduction
OKS specializes in high-performance lubricants for rolling bearings, focusing on reducing friction, wear, and corrosion. With 40 years of expertise, their products are developed in Germany, known for quality and reliability.

Functional Principle of Rolling Bearings
Rolling bearings enable friction-reduced rotary movements between machine components. They consist of inner and outer rings with rolling elements like balls or rollers, separated by a cage to minimize friction and wear. Ball bearings are ideal for high speeds, while roller bearings handle high loads.

Tasks of Rolling Bearing Lubricants
The primary goal of lubrication is to prevent metal contact and reduce sliding friction, enhancing wear protection, extending bearing life, and improving operational reliability. Lubricants also provide corrosion protection, heat extraction, noise damping, and support sealing effects.

Grease vs. Oil Lubrication
Grease lubrication is preferred for 90% of rolling bearings due to its low constructional demand, good sealing support, long usage periods, low frictional torque, and noise-dampening properties. Greases are suitable for a wide range of speeds and loads, except for axial spherical roller bearings.

Characteristics of Greases
Greases consist of a base oil bound by a thickener, providing effective friction and wear protection. Additives enhance corrosion and wear protection, load-bearing capacity, and resistance to aging.

Selection Criteria for Rolling Bearing Grease
Selection depends on bearing design, cage material, application conditions, temperature, speed, pressure, and environmental influences. Key characteristics include NLGI grade, drop point, four-ball test rig value, DN factor, and SKF-Emcor value.

Lubrication Procedures
Continuous lubricant supply is crucial for reliability. Follow manufacturer instructions for initial and renewed greasing. Relubrication should be done during operation, with quantities adjusted to avoid over-lubrication. Before switching greases, ensure compatibility and thorough cleaning.
