NORD SK 2282 UNICASE Parallel Shaft Gearmotor
The NORD SK 2282 is a compact, high-efficiency 2-stage parallel shaft helical gearmotor featuring NORD DRIVESYSTEMS' benchmark UNICASE single-piece cast iron housing[cite: 23]. Engineered for applications with tight mounting profiles[cite: 23], the SK 2282 provides superior torsional stiffness, leak-proof operational reliability, high overhung load capacity, and quiet gear transmission[cite: 23]. Available across flexible mounting configurations—including hollow shaft with keyway (SK 2282A), shrink disc (SK 2282ASH), B5 flange (SK 2282AF), B14 face flange (SK 2282AZ), keyless GRIPMAXX™ system (SK 2282AFMH), and rubber buffer torque arm (SK 2282G)[cite: 23]—it is widely specified in agitators, belt conveyors, crane hoists, wastewater aerators, and automated warehouse systems[cite: 23].

Expert Selection & Retrofit Engineering Notes
When retrofitting an existing installation featuring older SK 1282, SK 2282, or competitor parallel shaft gearboxes[cite: 23], upgrading to current UNICASE block housing gearmotors ensures complete dimensional interchangeability while substantially increasing radial load capacity and oil seal longevity. Simply provide us with your existing NORD serial number or nameplate code, and our engineering team will deliver a 100% compliant replacement specification and proposal.
