Sintered Iron Oil Retaining Bearing

DALON SINTERED IRON BUSHING INTRODUCTION:

DALON SINTERED IRON BUSHING are manufactured of pressed iron powders by sintered technology and impregnated with lubricating oil and high porosity.

Increased iron content makes these SINTERED IRON BUSHING stronger and more resistant to shock loads than standard oil-embedded bushing; they can operate at lower speeds.

Startup friction causes these porous SINTERED IRON BUSHING to release a thin layer of oil on the bearing’s surface. The oil contained in the porosity provides a constant lubrication between bearing and shaft, which resulting in a very low friction coefficient and maintenance-free for general engineering applications.

Load Direction:

All Sintered Iron Oil Retaining Bearing is designed to handle radial loads, thrust loads, or a combination of the two. Radial loads are perpendicular to the shaft.

Thrust loads are parallel to the shaft.

Sleeve bearings handle radial loads.

Flanged sleeve bearings handle both radial and thrust loads.

Thrust bearings handle thrust loads.

DALON BUSHING ADVANTAGE:

With no moving parts, Sintered Iron Oil Retaining Bearing are the simplest type of bearing. Compared to ball and roller bearings, they generally handle higher temperatures and perform better in dirty environments. They are also intended by design to be self-lubricating, maintenance free and low cost.
