NORD DRIVESYSTEMS Gearmotors & Speed Reducers
NORD DRIVESYSTEMS is world-renowned for developing the revolutionary UNICASE block housing[cite: 13], providing maximum radial and axial load capacity, superior torsional strength, and quiet operation[cite: 13]. Explore our comprehensive selection of NORD Standard Gearmotors (NORDBLOC.1 Helical, Parallel Shaft, NORDBLOC.1 Bevel, and UNIVERSAL Worm) and MAXXDRIVE® Heavy-Duty Industrial Gear Units[cite: 13]. WE DRIVE HONGKONG LIMITED supplies 100% original NORD gearmotors, AC motors, and drive electronics with fast worldwide express delivery.
Invented by NORD in 1981, the single-piece UNICASE block housing integrates all bearing seats into a single solid casting, completely eliminating split-casing joints and sealing surfaces under heavy overhung loads[cite: 13].
Engineering Advantage & Technical Ecosystem:
• UNICASE Housing Stiffness: Maximum gear mesh precision, long fatigue life, and absolute leak-proof reliability even under continuous vibration.
• High Power Density & Efficiency: IE3 and IE4 energy-efficient motor options paired with high-performance helical gear stages achieving up to 98% efficiency.
• nsd tupH Surface Treatment: Sealed corrosion protection treatment for aluminum housings, making NORD gear units corrosion-proof against washdown chemicals in food, beverage, and pharmaceutical plants.
• WE DRIVE HONGKONG LIMITED provides technical sizing, ratio verification, and global express supply.
Compact inline, right-angle, and parallel shaft geared motors for material handling, intralogistics, and process automation.

NORD UNICASE Replacement & Technical Retrofit Guide
Direct replacement guide for upgrading conventional split-case gearboxes to rigid NORD UNICASE units:
| Conventional Split-Housing Gearbox | Common Failure / Maintenance Risk | Current NORD UNICASE Equivalent | Key Mechanical & Performance Upgrades |
|---|---|---|---|
| Split-Casing Inline Helical Gearbox | Oil leaks at housing split seam due to torsional frame flexing | NORD NORDBLOC.1 Helical 100% UNICASE Block | Solid single-piece casting completely prevents oil leaks and gear misalignment. |
| Cast Iron Drive in Food/Washdown Zone | Paint chipping and rust under caustic cleaning chemical washdown | NORD Aluminum Unit + nsd tupH nsd tupH Treatment | Sealed corrosion protection makes aluminum casing 20x harder than standard paint. |
| Conventional Shaft Reducer on Conveyor | Shaft keyway wallowing and difficulty in disassembly | NORD Parallel Shaft with SafeomiX® Keyless Bushing | Keyless shrink disc / SafeomiX hub enables easy mounting and 100% torque transmission. |
