Product Name: BIT Piston Large Sealing O-ring PACKING. Compatible Model: YAMAHA YS12 High-speed Mounter BIT Nozzle Shaft Piston Assembly. Product Properties: Brand New Original, FKM Fluororubber Material. Product Description: The main large sealing o-ring for the BIT shaft piston, used together with the small o-ring. O-rings tend to age and swell after long-term reciprocating movement, which causes head vacuum leakage, unstable component picking and placement offset. It is a core wearing part of the head maintenance kit.
YS12 BIT Large O-ring, special sealing o-ring for the BIT piston of Yamaha YS12 mounter, brand new original, made of high-quality fluororubber. It features anti-aging performance, resistance to reciprocating friction, and can withstand erosion from workshop dust and oil contamination. As the main seal for the BIT piston, it maintains the tightness of the head vacuum circuit, reduces vacuum decay, and improves faults such as component slipping during pickup, component dropping and poor placement accuracy. It is an SMT Yamaha YS12 head maintenance spare part with sufficient stock. It can be purchased as a set together with the BIT small o-ring, and sample orders and bulk orders are supported.
