details Industrial grease is a kind of grease, the key for industrial production and manufacturing, divided into three categories: general purpose grease, long-acting grease, special grease。General-purpose greases are mainly greases with mineral oil as the base oil and lithium as the thickener, which are applied to the general temperature range and general standards。If you need a grease with unique ingredients or a wider temperature range, this is the time to use long-acting greases, special greases forBe uniqueStandard lubrication。Each type of grease is packaged in a different color: white - general purpose grease, light yellow - long-acting grease, dark gray - special grease。
The selection of grease is immediately related to the service life and function of the rolling bearing。In order to make the rolling bearing work well.Ideally, the selection of lubricants needs to pay attention to the following criteria:
· Operating temperature
·负载
· Type of rolling bearing (rollover or drag)
· Speed ratio
· Lubrication method (splash lubrication, management center lubrication, etc.)
· Natural environment (moisture, acid value, whether it is in contact with food)
Application level
Includes NLGL grade, base oil type, base oil viscosity, thickener, etc
NLGL requires the following application levels of greases:
1#2#3# grease is used for roller bearings, where 2# grease is.familiar。In the management center lubrication system software, generally used soft greases, from 000 to 2
The type of base oil can be mineral oil, synthetic oil or edible oil。Synthetic oils have a wide range of application temperatures。The viscosity of the base oil determines the thickness of the oil slick. The greater the viscosity, the smaller the speed ratio allowed by the rolling bearing. When the viscosity is low, the speed ratio is high。
.Common greases are: calcium base grease, calcium base grease, lithium base grease。Some solid preservatives, such as molybdenum disulfide or high purity graphite, can also be added to greases to improve their boundary lubrication properties。
Calcium-based greases do not dissolve water and have good organic chemical reliability and can be used at high temperatures of 100 ° C。
Calcium grease can not touch water, so it can not be used in wet cold rolling bearings, but this kind of commodity stiffness is good, can be used for toothed such as transmission gear such lubrication。
Lithium base grease application.Universal, good fire resistance hydraulic oil and wide application temperature range。
The resulting grease can be used at higher temperatures, has high organic chemical reliability, moisture resistance to corrosion, high resistance to fire and hydraulic oil, and has a longer service life than traditional greases。
