HEF - Bushings

PEL bushings have an excellent resistance to wear and seizure thanks to the combination of a duplex surface treatment and a special surface topography. This cross hatching topography provides grease reservoirs in the loaded area and enables removing of abrasive particles. They are appropriated to work in severe working conditions: high pressure, abrasion, shocks and corrosion. PEL LV bushings are an alternative with no cross hatching on the ID. They offer really good performances (wear and seizure resistance…) under high static loads (low dynamic pressure) and by small oscillating movement.

HEF DURFERRIT - Bushings for Industrial Applications

PEL® bushings are engineered with advanced duplex surface treatment and a unique hatching topography, enhancing resistance to wear, seizure, and abrasion. This design incorporates grease reservoirs in critical areas and aids in the removal of abrasive particles, making them suitable for challenging environments characterized by high pressure and corrosion. The PEL® LV variant offers high performance under static loads with small oscillations, excluding cross hatching on the ID. Optimal performance requires a mating shaft with surface roughness below Ra 0.8 μm and hardness above 56 HRC. PEL® bushings extend lubrication intervals up to 50 hours, depending on specific working conditions. They find applications across industries such as steel, glass, construction, railways, agriculture, and other production sectors.
