We offer a range of quality lubricants to supply an exact match to each application.

CeramicSpeed offers a range of commercially available quality lubricants to supply an exact match to each application and customer.

Lubricants are critical in allowing ball and roller bearings to function optimally. Correct lubrication is essential for the service life of the bearing as well as for the temperatures and noise levels. 

Properly lubricated, CeramicSpeed bearings have even longer service lives, are more reliable and even better protected against contamination and corrosion.


Lubricant composition

Bearing lubricants contain three main ingredients:

  • Base oil: Mineral or synthetic oils
  • Soap/thickener to ensure that the oil remains in place
  • Additives to optimise lubricant properties

How to choose the right lubricant

There are several factors to consider when choosing the right lubricant:


Temperature range

The lubricant must match the operating temperature range of the bearing - a poorly matched lubricant will significantly reduce bearing life time.


Base oil viscosity

Generally speaking, high loads and low RPMs require high base oil viscosity. Low loads and high RPMs require low base oil viscosity. If in doubt, contact us and we will assist you.


Typical choice of viscosity:

  • Spindle bearings > 10,000 RPM/min: 20 - 40 [cSt]
  • Electrical motors < 3,000 RPM/min: 80 - 120 [cSt]
  • Main bearing in wind turbine rotor < 20 RPM/min: 200 - 400 [cSt] at 40 °C

CeramicSpeed SLT

CeramicSpeed SLT is a polymer matrix saturated with lubrication oil. The matrix secures to retain oil right on the functional surfaces of the bearing under even very harsh conditions, while at the same time preventing moisture and foreign particles from entering the bearing. Focus applications: Environments with sever particle contaminating, Applications in moist surroundings - even under splash water influence, Chemical, pharmaceutical or other applications, where no liquid lubricant can be allowed.

Other important factors

The choice of lubrication is also impacted by factors such as:

  • Food industry requirements (FDA/EC 1935)
  • Noise limitations
  • Corrosion protection


Lubrication intervals

The optimal lubrication interval is 0.5 - 0.7 times the theoretical lubricant service life. This can be found in the technical documentation of the lubrication supplier.


Lubrication volume

The correct lubrication volume can be found using this formula:

 D*B*X = M


D = bearing outer diameter in mm

B = bearing width in mm

X = 0.002 (weekly lubrication / 0.003 (monthly lubrication) / 0.004 (annual lubrication)


Miscibility matrix

Base oil miscibility (+ = miscible / +/- = partly miscible / - = immiscible)
