Hydraulic Road Roller Compactor Small-sized road rollers are also called walk-behind rollers. At present, small-sized road rollers produced in China are divided into three types: walk-behind single-wheel rollers; walk-behind two-wheel rollers; and ride-on rollers.

The methods of impregnation are:
1. The impregnation is brought into a molten state and vacuum impregnated.
2. A hardening liquid is used as a carrier, and the impregnation is placed therein for impregnation.
3. Using a volatile liquid as a carrier, the impregnation is dispersed therein for impregnation, and then the liquid is volatilized.
4. The impregnation is vaporized and then impregnated.
The impregnate not only acts as a lubricant, but also increases the strength of the matrix material.
Engines are divided into diesel engines and gasoline engines.
Mainly composed of engine, hydraulic system, steel ring, vibration exciter and operating handle
The structure of the roller is very simple, small in size, compact in structure, easy to transport, powerful in work, and high in efficiency.
Impregnated composite bearing
The porous material is impregnated with a porous material to form a solid-lubricated impregnated composite bearing, and the solid lubricant stored inside the bearing bush continuously supplies a solid lubricant to the friction surface as the bearing pad wears. A typical composite bearing is made of carbon graphite as a matrix material, impregnated with soft metal, polytetrafluoroethylene or inorganic material (BaF2).
