Double acting metal wiper DKBW 25x37x6/9 PU95 + SPCC WYS/Korea, KOMATSU 07016-00256,VOLVO 9564-20250
Double acting metal wiper, design DKBW.
The DKBW profile is a double-acting seal made of thermoplastic PU95 bonded by a phosphating process to a base of SPCC (Steel Plate Cold Rolled Commercial – standard, widely used cold-rolled carbon steel.).The hot phosphating process protects the steel base from surface rust during storage in the warehouse and guarantees eternal molecular adhesion between the metal and the polyurethane under high pressure.

ØD=30 mm ; Ød=42 mm ; t=6 mm ; H=9 mm
Advantages
Very good wiping effect, both internally and externally
Excellent abrasion and wear resistance
