Marginal-lubricating Bearings

HLDB Metal-polymer marginal-lubricating bearings consist of low carbon steel and sintered bronze in the middle with POM compounded on the surface. Low-carbon steel provides exceptionally high load carrying capacity and excellent heat dissipation. Sintered bronze powder provides good thermal conductivity away from the bushing surface , also serves a reservoir for the resin mixture. POM has a high wear resistance and low friction with a pattern of circular indents which should be filled with grease when assembling the bearing. HLDB-20 series sliding bearings is suitable for rotating and oscillation movement, less maintenance requirements due to the long re-lubrication intervals by its good abrasive resistance and low friction factor.
