Technical Advantages & Materials
High-Quality Component Features
Premium Housing: ADC12 Die-cast aluminum with aging treatment and high-durability powder coating (>0.2mm). Heat resistance up to 150°C.
Advanced Transmission:
①Worm Gear: Aluminum bronze alloy forged for strength.
②Shaft: 40Cr heat-treated steel with anti-rust blackening.
③Spline Connection: Ensures high torque transfer and prevents shaft fracture.
Industrial Motor: Designed for 1.3-1.5x rated torque to handle frequent starts and heavy-duty cycles.
Precision Bearings: Uses EMQ (ZV2) P6-grade low-noise bearings for smooth operation.
Sealing & Lubrication: Equipped with German Oberst double-lip TC oil seals and Mobil synthetic grease for maintenance-free long life.

Rigorous Quality Control (Testing Process)
Every OMK-05B unit undergoes four strict tests before delivery:
-
Torque Test: Verified to reach 1.3x rated torque safety margin.
-
Insulation Test: 1500V high-voltage breakdown test for 1 minute.
-
Load Test: Batch samples are tested under full load for 48 hours.
-
Sealing Test: Submerged IP68 test with 0.2Mpa internal air pressure to ensure zero leakage.
