The year-round outdoor operation of metro and high-speed rail systems places great demands on the durability of vehicle linkage mechanisms, and the need for a clean interior environment implies that moving parts may not use lubricants.
Train Brake System
CRG high-load filament-wound bearings: used in train brakesystem; these durable bearings can withstand 160Mpa radial pressure, and can operate outdoors under high loads maintenance-free;
EPB12 plastic plain bearings:enables superior movement under high load conditions; can be used in door system open/close actuating mechanisms;
LIN plastic linear bearings: used in door system switch motion guidance mechanisms;achieves true maintenance-free,noiseless operation;
EPB3 plastic plain bearings: used in the seat system back angle adjustment mechanism, and achieves smooth, noiseless adjustment; EPB3 plastic plain bearings suffered nearly imperceptible wear after 250,000 cycles of testing under a heavy load while used on CSB high-speed rail seats;
EPB3 plastic plain bearings: used in windshield linkage mechanism;offers permanent maintenance-free operation;
CRB fiber-wound bearing sand EPB5 plastic sleeves: used in the swinging portion of high-speed rail pantograph joints, and achieve maintenance-free operation;
