There are two ways to select the lubrication of an INA bearing: oil lubrication and grease lubrication. There are advantages and disadvantages to each of these two lubrication methods.
Grease lubrication
Generally rolling INA bearings are greased. Its main advantages are:
Design is very simple
Grease can seal a lot
Low maintenance costs and long service life
Under normal working and environmental conditions, it is possible for oils to achieve “lifetime lubrication”. If under high load conditions (speed, temperature, load), the grease must be replaced periodically. In order to replace the grease, it is necessary to set up pipes for supplying and removing grease and collecting used grease collectors. For short-term grease replacement, the necessary grease-injected pumps and valves should be provided.
Oil lubrication
When the mechanical parts near the INA bearing have been lubricated with oil or need to be cooled by lubricating oil, the INA bearing should be oil lubricated. There may be heat dissipation requirements when the INA bearing is under heavy load or high speed, or when external heat is introduced.
Micro-lubrication methods, such as drip lubrication, oil mist lubrication or oil and gas lubrication, ensure that the oil loss and INA bearing friction are small.
When air is used as the carrier, the oil can be supplied directly and the gas flow helps to seal.
INA Bearings are extremely fast and require good cooling of the fruit, allowing a large amount of lubricant to be sprayed directly onto all contact surfaces.
