Lubricant selection
Selecting a grease can be a delicate process. SKF has developed several tools in order to facilitate the selection of the most suitable lubricant. The wide range of tools available includes those from easy-to-use application driven tables to advanced software allowing for grease selection based upon detailed working conditions.
Basic grease selection
The basic grease selection chart provides you with quick suggestions on the most commonly used greases in typical applications.
| Basic grease selection table | ||
|---|---|---|
| Generally use if: |
|
|
| Speed: rotational speed1) up to 300 000 2)
Temperature: 50 to 100 °C (120 to 230 °F) Load: C/P ~8 3) | LGMT 2 | General purpose |
| Unless |
|
|
| Expected bearing temperature continuously > 100 °C (210 °F) | LGHP 2 | High temperature |
| Expected bearing temperature continuously > 150 °C (300 °F), demands for radiation resistance | LGET 2 | Extremely high temperature |
| Low ambient –50 °C (–60 °F), expected bearing temperature < 50 °C (120 °F) | LGLT 2 | Low temperature |
| Shock loads, heavy loads, frequent start-up / shut-down | LGHB 2 | High load |
| Food processing industry | LGFP 2 | Food grade |
| Biodegradable, demands for low toxicity | LGGB 2 | Biodegradable |
1) rotational speed = rotational speed, r/min x 0.5 (D+d), mm.
2) for ball bearings, spherical roller bearings, tapered roller bearings and CARB bearings rotational speed up to 210 000 and for cylindrical roller bearings rotational speed up to 270.000.
3) C/P = load ratio, where C = basic dynamic load rating, kN , and P = equivalent dynamic bearing load, kN.

Grease selection chart
The Grease selection chart (PDF, see link below) provides you with a complete overview of SKF greases. The chart includes the main selection parameters, such as temperature, speed and load, as well as additional performance information.
LubeSelect for SKF Greases
LubeSelect for SKF Greases (see link below) provides you a user friendly online tool to select the right grease and suggest lubrication frequency and quantity, while taking the particular conditions of your application into account. General guidelines for typical greases for different applications are also available.
