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.
