DNB03 is a solid lubricant plugged type bearing using a newly developed high hardness special copper alloy as base metal. Under a high bearing pressure, it exhibits excellent wear resistance.
Features
¡ñApplicable to high loads even higher than DNB02
¡ñOutstanding wear resistance for high load and low velocity operations

Service Range
Lub state Self-lub Periodical lub
Service temperature range -40~+150
