By eliminating lubricants and reducing maintenance to reduce costs and increase service life, all products are available from stock – this is the core philosophy and goal of all Romiller engineering plastic bearings.

Linacent? engineering plastic linear bearing is a linear motion system with self-lubricating characteristics. The difference between it and metal linear bearing is that the metal linear bearing is rolling friction, and the point contact between the bearing and the cylindrical shaft is suitable for low-load high-speed movement; The plastic linear bearing is sliding friction, and the bearing is in surface contact with the cylindrical shaft, which is suitable for high-speed medium-low speed movement.

Romroll? joint bearings are designed to withstand harsh environments. Plastic bearings are resistant to corrosion in wet or watery areas and are resistant to weak acids and weak bases. Operating temperatures range from -30 to 80 °C. It is characterized by dirt resistance, dust, lubrication-free, maintenance-free, able to withstand certain loads, and good shock absorption.

Gear? engineering plastic helical gears, the most common spiral bevel gears and hypoid gears, have found important applications in many industries, particularly in the automotive industry. The helical gear is one of the main parts of the mechanical transmission system. Its tooth surface structure is complex, the structure of the cutting machine and its machining adjustment are the most complicated. At the same time, the machining tool, machine tool parameter setting, loading deformation and assembly error will cause its meshing, bearing and vibration. The change in performance makes the quality control of the helical gear in design and manufacture extremely difficult.

Polyimide parts have high chemical stability, mechanical toughness, natural lubrication and high temperature insulation. It can reduce the weight of parts, extend the maintenance interval or life, and reduce the overall cost by increasing the process uptime. It is an ideal design material with long-term use temperature of -196-300 °C and short-term temperature of 380 °C.

The long-term use temperature of such materials is between 150 ° C and 400 ° C. They retain good performance during long-term high temperatures, such as sliding friction and chemical resistance. Adding glass fiber, glass beads or carbon fiber to the material can further improve the thermal deformation resistance and rigidity of the material. The addition of additives such as PTFE, graphite and aramid fibers to the material can improve the sliding friction properties of the material, and the addition of metal fibers and carbon black can improve the electrical conductivity of the material.
