Rolling bearing filling grease refer to the following principles:

(1) The general bearing should not be filled with grease, in order to load into the bearing cavity of the whole space of 1/2-3/4 can be;

(2) the horizontal bearing is filled with 2/3 to 3/4 of the inner cavity space;

(3) The vertically mounted bearing is filled with 1/2 (upper side) and 3/4 (lower side) of the cavity space;

(4) In the environment prone to pollution, for low or medium speed bearings, all the space in the bearing and bearing box should be filled;

(5) High-speed bearings should be placed in high quality lubricating oil before greasing, generally soaked in the base oil of the bearing grease to be filled, so as not to burn out the bearing due to insufficient friction surface grease when starting.

The addition of grease should be appropriate

How to prevent grease from adding more? First of all, the reasonable amount of grease should be determined. In addition, the operating specifications for the amount of grease to be added should be formulated. After adding and replacing grease, attention should be paid to temperature, noise, vibration, etc., and whether there is oil leakage. Specialized monitoring tools can also be used for critical equipment. Reasonable amount of grease specified:

The amount of grease added to bearings can refer to this formula:

G=0.005 DB

Here:

G=weight of fat, grams

D=bearing outer diameter, mm

B=bearing width, mm

or

G=0.114 DB

Here, D and B are in inches.

If you use butter gun grease, you should calculate how much grease the butter gun can hit each time, you can use an electronic scale, use a good butter gun, calculate how many times to hit.

How to prevent excessive addition of grease?

In addition to knowing the amount of grease added, certain methods also help prevent excessive fatting:

When adding fat, stop adding fat if you feel difficulty, obstruction or start to feel a large reaction force.

When adding grease, the grease outlet should be kept unobstructed to prevent dry grease from blocking the hole.

If necessary, small accessories such as butter gun pressure gauge, pressure relief grease nozzle can also be used to facilitate the effect.

Slow greasing, too fast and too fast easy to cause sealing problems, is not conducive to the uniform distribution of grease in the bearing.
