China 286320 Finger for CNH Combine Harvester | OEM Replacement Manufacturers, Factories

We manufacture this guard from premium chromium-silicon spring steel 55SiCrA / 54SiCr6. Compared with ordinary carbon steel alternatives, this material delivers better fatigue resistance and stability under long-hour high-frequency reciprocating cutting. We adopt hot forging molding, followed by local induction hardening on the finger tips. Hardened contact surfaces resist abrasion, while the main body retains proper toughness to avoid cracking when hitting rocks and stubble.
All dimensions strictly follow OEM specifications. Square mounting openings match original installation standards, enabling direct bolt-on replacement without any modification. Well-controlled assembly clearance ensures smooth cooperation with sickle sections, lowering cutterbar vibration and extending the service life of the whole cutting set.
