Description
This is a NORD SK series parallel / inline helical speed reducer (gearbox) designated SK 5282AZ SEP215. It’s built for industrial duty, designed to take a higher-speed input (from an electric motor) and reduce its speed while increasing torque for use in heavy machinery. The cast iron housing, engineered internals, seals, and modular design make it suitable for demanding environments.
What It Does
- Receives rotational input from a motor or power source
- Reduces that input speed via internal helical (parallel shaft) gearing
- Delivers high torque output to drive mechanical equipment (rollers, screws, extruders, etc.)
- Maintains alignment, supports loads, and protects internal gears via sealing and lubrication
Capabilities
- Transmit high torque loads (24,419 lb-in as per nameplate)
- Operate continuously under moderate to heavy duty
- Handle radial and limited axial loads (depending on gear geometry and bearings)
- Withstand industrial environments with dust, vibration, and possible particulate ingress (with proper sealing)
- Be used in processes like plastic extrusion lines where precise, smooth torque is needed
Core Function
- Speed reduction (lower output rpm than input)
- Torque multiplication (higher force at slower speed)
- Load transmission and mechanical coupling
- Vibration damping / alignment control
- Lubrication and protection of internal components
Design Features & Benefits
- Rigid one-piece casting (UNICASE style): prevents distortion, keeps seals and bearings in alignment
- Helical gearing: smoother and quieter than spur gear, better efficiency
- Advanced sealing (multi-lip, possibly “QuadraLip” style in NORD’s line): helps retain lubricant and exclude contaminants (as found in other SK models)
- Auto-vent breather (or “AUTOVENT” style) to regulate internal pressure and reduce seal stress (common in NORD SK line)
- Modular input/output adaptability: NORD’s gearboxes often allow different shaft or flange input configurations, hollow or solid output shafts, etc.
- Corrosion and wear resistance: protective coatings and durable surfaces (standard in NORD SK catalog)
- Service features: fill / drain ports, inspection covers (depending variant)
Applications & Industries
- Plastic extrusion lines (drive extruder screws, pullers, haul-offs)
- Material handling (conveyors, belt drives)
- Mixers, agitators, shredders
- Pumps, fans, blowers
- Packaging and processing equipment
- Mining, chemical, plastics, food, bulk material industries
- Anywhere a precise, reliable low-speed, high-torque drive is needed
Machine Overview & Summary
This NORD SK 5282AZ SEP215 speed reducer is an industrial-grade parallel / inline helical gearbox built for durability and performance. With a rated torque of approximately 24,419 lb-in and a service factor of 1.00, it’s suited for medium to heavy-duty applications. The robust cast housing, helical gear design, and advanced sealing features help ensure smooth, reliable
