Lubrication intervals and amounts of grease needed for replacement

The first relubrication and grease change of the bearing should be done immediately after the bearing is installed before the grease has evaporated from the sealing seals all the way around the circumference.

The grease (or oil) will deteriorate over time due to the mechanical stress to which it is subjected. Therefore, according to the conditions and frequency of use, the bearing grease should be replaced at regular intervals.
Diagram 1 shows the recommended values for grease change based on experience. Curve 1 represents values for bearing grooves and curve 2 represents values for the bearing. For operating temperatures above 70°C, in dusty and humid environments, the lubricant change intervals should be shortened.

The amount of fresh grease depends on the size of the bearing. Diagram 2 shows the amount that is recommended to be applied to the grooves during each relubrication. Curve 1 is shown for single-row bearings with balls or rollers and curve 2 is for bearings with two or three rows of rollers.

If it is necessary to use a centralized automatic or semi-automatic lubrication system, the bearing should be rotated during lubrication change to ensure proper distribution of material.

The new grease must be identical or capable of mixing with the grease already in the bearing. Mixing two immiscible greases will adversely affect the effectiveness of the grease.

To ensure good protection and lubrication, the space between the rings must be completely filled.
Lubricant can be applied to the gear by brush, spraying, or any other suitable method (the amount depends on the method chosen).
Before relubricating, the tines should be cleaned of any contaminants.
