Bearing boundary grease injection method

The skf bearings boundary lubrication has the following advantages:
1, the surface of the plastic layer can be left in the molding process a certain margin, own processing after the assembly pressure holing hole to better assembly size.
2, the products are mainly used in automotive chassis, metallurgical machinery, mining machinery, irrigation machinery, construction machinery, agricultural machinery, steel rolling equipment, etc..
3, suitable for high load low speed rotary motion, rocking movement and often load open and close frequently difficult to form hydrodynamic lubrication occasions.
Under boundary lubrication conditions for long periods of refueling and maintenance, refueling over layer so fag bearings last longer.
Whether the high-pressure, low-pressure, high-temperature, low temperature, oil lubrication oil lubrication or water lubrication can adapt. The product matrix Colliers brass, doubling than the copper sleeve hardness, wear resistance more than doubling.
nsk bearings grease injection method has four main, they are fat cup smear method, fat the marksmanship and concentrated to fat method.
The first: grease cup
Open a small hole leading to the grease cup bearing next, constantly replenished by cup grease to the bearing. Should be set to the high speed bearings seborrheic valve, the TIMKEN bearings excessive lipid thrown by the effect of centrifugal force when the bearing rotation, in order to reduce the friction of the bearings and the high speed rotation to bring the temperature increases.
Second: smearing
When applied to use special tools, can not use bare hands. The fatliquoring amount is required to comply with the above requirements, the grease covered all require lubrication INA bearings surface. Used after a certain period in the grease, the need for fat or grease filling.
Third: fat marksmanship
Pressure grease gun through the grease through the the fatliquoring hole into the bearing, the method used to make up the grease.
Fourth: centralized greasing Law
Bearing parts pump unified exports through the pipeline will be fat, the flow of new oil line should be able to squeeze the old and fat make up the new grease into the lubrication point.
