Product Description

Door-Hinge solutions PTFE Bushings 

PTFE lined self-lubricating bearing also called DU bushing, dry bushing, DU bearing, bushing,PTFE coated bearing,SF-1 oilless bearing,PTFE liner metal polymer composite bearing and PTFE based plain bearing. This type of DU bush takes PTFE layer as sliding layer which makes products can perform very well under dry condition or oil condition.

self-lubricating bearing bushings material has good thermal conductivity, and wear resistance. The stainless steel backing improves the mechanical strength of the bearing as well as to allow thicker bearing wall designation requirement. Stainless steel has a good chemical resistance feature.

Standard Wall Thickness mm 0.75   Max.Load Room Temp 120N/mm²
1.00 Max.speed Dry running 1m/s
1.50 Operation Temperature range -195℃~+260℃
  Friction coefficient 0.03~0.20

Advantages

 

Improved energy efficiency with the low friction performance of PTFE-enriched overlay;
Extended service life with a high wear-resistant bronze layer;
Zero maintenance as self-lubricating bearings can operate dry without grease;
Greater reliability than bimetallic bearings by avoiding potential shaft/bearing seizure under boundary lubricated conditions and frequent stop/start operation;
Compact, lightweight designs with thin-wall bearing construction;
Reduced noise with no metal-to-metal contact between the bearing and the shaft;
Quick, simple assembly without expensive mounting tools.
