Coatings, what we usually call paint is just one of them. Refers to a type of liquid or solid material that is applied to the surface of an object to form a thin film under certain conditions to protect, decorate or otherwise perform special functions (insulation, rust prevention, mildew proofing, heat resistance, etc.). Solvent-based paint is a kind of volatile paint formulated with macromolecule synthetic resin as main film-forming substance, organic solvent as diluent, a certain amount of pigments, fillers and auxiliaries, mixed, stirred and dissolved, and ground. After brushing on the outer wall, the film-forming substance and other non-volatile components together form a continuous and continuous thin film, ie coating, as the solvent contained in the paint volatilizes. Due to the tightness of the coating, it usually has good hardness, gloss, water resistance, acid and alkali resistance, good weather resistance, and pollution resistance. However, due to the volatilization of organic solvents that are easily tolerated during construction, it is easy to pollute the environment.

The film has poor air permeability and hydrophobicity. If it is applied on a wet grass floor, it can easily cause peeling and peeling. For these reasons, the amount of such exterior paints at home and abroad is lower than that of emulsion-type exterior wall paints. The solvent-based acrylic exterior wall coatings developed in recent years have outstanding weather resistance and decorative properties. The durability period is more than 10 years. The construction period is also short and can be used at lower temperatures. Overseas weather resistance and water resistance are very good, and it has a high elasticity polyurethane exterior wall coating. The durability period can reach more than 15 years.

Pillow blocks are advanced applied in places with simple equipment and spare parts, such as agricultural machines, convey system or construction machines. One unit of pillow block consists of deep groove ball bearings with spherical outer rings closed in double sides and a housing made by gray cast iron or punches steel.
A Pillow Block Bearing (Plummer block) is a mounted bearing used to provide support for a rotating shaft with the mounting surface on a parallel line with the axis of the shaft.
Pillow block bearings are generally self-lubricating.
Pillow block bearings are a form of mounted bearing used to provide load support for a rotating shaft axis. The bearing housing mounts to a surface parallel to the shaft axis. Selection of the appropriate bearings can be accomplished based on the shaft size and the radial and thrust load requirements. Pillow block bearings are designed to support a shaft: the mounting surface is on a parallel line with the axis of the shaft. Elongated bolt holes in the base or feet of the unit allow for some adjustment and easy mounting of the pillow block bearing.
