Technical Advantages & Materials
1. Robust Housing & Sealing
-
Material: ADC12 Die-cast aluminum alloy.
-
Finishing: Shot-blasting and powder coating (>0.2mm thickness) with thermal resistance exceeding 150°C.
-
Sealing: Equipped with imported German Oberst double-lip TC oil seals and O-rings.
2. High-Precision Transmission System
-
Worm Gear: Forged aluminum bronze alloy.
-
Output Shaft: Made of 40Cr heat-treated steel with a black rust-proof finish.
-
Spline Connection: Uses a reliable spline interface between the output shaft and gear to prevent the torsional fractures common in integrated structures.
