Durbal DG 18 PW maintenance-free articulated bearing steel/brass+PTFE

Product detailed description

Durbal DG 18 PW is a maintenance-free radial spherical plain bearing designed for applications requiring reliable and long-term operation without the need for additional lubrication. The bearing is made of a combination of steel, brass and PTFE, which guarantees high wear resistance and a low coefficient of friction. The inner diameter of the bearing is 18 mm, the outer diameter is 35 mm and the overall width is 23 mm, with a C width of 16.5 mm.

The bearing is designed with a double-sided widened inner ring and a standard outer ring, which improves its mechanical properties and allows better load distribution. The bore profile is cylindrical, which is a common solution for this type of bearing. The bearing is unsealed, which means it is not protected from external contaminants, but its maintenance-free design ensures that no additional lubrication or maintenance is required during its service life.

The operating temperature of the bearing is in the range of -20 °C to +110 °C, while the material composition allows for short-term loads of up to +200 °C. The weight of the bearing is 0.125 kg, which is optimal for its size and design. Thanks to the use of PTFE (polytetrafluoroethylene) in combination with steel and brass, the bearing provides excellent sliding properties and reduces friction, which extends its service life and increases reliability in demanding conditions.

Durbal DG 18 PW is an ideal solution for applications where low maintenance and high reliability are important, such as industrial machinery, transport equipment or other mechanical systems where smooth and quiet operation is required.
