Greases are lubricants in solid or semi-fluid form consisting of a mixture of base oil, thickener and additives. Unlike liquid mineral oils, they do not tend to move away from the lubrication point. Greases with various thickener types (calcium, lithium, urea, etc.) contain additives specific to the applications they will be used in. They extend the life of the system by protecting both the system components and the general construction by reducing the wear on toothless, geared and moving metal systems, especially in industry. Greases, which reduce maintenance and repair stops, also help to increase the efficiency of production with these features.

The main points to be considered in the selection of grease are as follows:

• Working environment

• Expected temperature resistance range

• The load to be exposed

• Movement speed in the system

Adhesives are a general name given to 1 or 2 component substances used for bonding, holding or fixing 2 surfaces. They are widely used both for daily use in homes and for production and maintenance and repair purposes in industry. There are adhesive types that are shaped according to many features such as the intended use, the parts to be bonded, the surface and the way of use. For this reason, the main points to be considered in the selection of adhesive for the success of the application can be listed as follows:

• Type of surface to be applied
• Surface cleaning
• Desired curing time
• Desired curing force
• Chemical type of adhesive
• Temperature resistance range
• Environment
