EP-NMRV063 Medium-Duty Aluminium Worm Reducer
Cái EP-NMRV063 is where the NMRV series transitions from light-duty to genuine medium-industrial capability. At 6.2 kg with 63 mm centre distance, it delivers up to 167 Nm output torque – enough for multi-lane conveyor drives, construction hoist mechanisms, and heavy-duty packaging machinery that smaller frames simply cannot handle. The NMRV063 accepts IEC motor frames from 56 to 90, covering input powers up to 1.1 kW – adding frame 90 support that the NMRV050 does not offer. A unique five-flange option set including FA, FB, FC, FD, and FE provides the widest mounting flexibility in the entire NMRV range. Output shaft is Ø25 mm standard with optional Ø28 mm for applications requiring heavier shaft load capacity. For extreme ratios, the NMRV063 pairs with NMRV130 as output stage reaching 5000:1 in double-stage configurations with up to 2430 Nm output torque.

✓ Các tính năng và lợi ích chính
Handles multi-lane conveyors, construction hoists, and heavy packaging drives that exceed NMRV050 capacity. The first truly medium-duty frame in the NMRV aluminium series.
FA, FB, FC, FD plus the FE flange unique to the NMRV063 – a compact PCD option for tight-space direct machine mounting. The widest output flange selection in the entire NMRV range.
Accepts motors from 0.25 kW micro-drives to 1.1 kW medium-duty applications. Frame 90 support makes the NMRV063 the smallest NMRV size suitable for 1.1 kW motor input.
Still approximately half the weight of a comparable cast iron reducer – practical for field installation on construction and mining equipment where manual handling is required.
⚙ Ứng dụng trong công nghiệp
Hoist mechanisms, concrete mixer drives, and portable conveyor head drives for construction sites. The aluminium weight advantage is critical for mobile equipment that must be transported between job sites.
Head and tail drives for light-to-medium duty ore and aggregate conveyors. 167 Nm handles loaded belt tension at moderate conveyor speeds. 6.2 kg enables underground installation without overhead crane.
Multi-lane product conveyors, palletiser infeed drives, and carton accumulation belt drives exceeding NMRV050 capacity. FE compact flange solves tight-space mounting on palletiser frames.
Clarifier drives, screw conveyor feed mechanisms, and sludge pump drives in treatment plant environments. Aluminium housing resists the humid and chemically aggressive atmosphere.
⚙ Hướng dẫn lựa chọn và vị trí lắp đặt
Select the NMRV063 for output torque requirements between 60 Nm and 167 Nm at input power up to 1.1 kW. Step up to the NMRV075 at 233 Nm for heavier loads. The NMRV050 at 89 Nm is more cost-effective for lighter applications. The NMRV063 is the first NMRV size offering 5 output flange options including the FE compact flange.

★ Đánh giá của khách hàng
“NMRV063 on our portable aggregate conveyor. 6.2 kg means two workers can lift and bolt it in 15 minutes on-site. 167 Nm handles the loaded belt without issue. Very impressed with the build quality.”
Craig M. – Desert Mining Services (Australia)
“The FE flange solved our tight-space mounting problem on the palletiser infeed. Direct machine mount without any bracket needed. Very versatile unit – five flange options from one product is excellent.”
Sophie L. – EuroPack GmbH (Germany)
“Running 5 units on our water treatment screw conveyors 24 hours a day, 7 days a week for 18 months. Aluminium handles the damp plant environment perfectly. No corrosion, no leaks.”
