A NORD gearbox nameplate contains all the critical data needed to identify the gearbox, order spare parts, verify installation configurations, and match replacement units. It includes various “identity information” and “parameters” for the machine. Among all the details, the two most important fields are the NORD Gearbox Model (Type) and Serial Number, which together uniquely identify your gearbox. In reality, to read a NORD gearbox nameplate, you only need to focus on 3 core things.

Where is the Nameplate and How to Find It Quickly?

If your equipment is an integrated “motor + gearbox” unit, do not look at the aluminum plate on the motor (that handles electricity and power). Instead, look for the “big chunk of iron (gearbox)” rather than the cylinder (motor). The nameplate is affixed directly to the cast iron or aluminum gearbox housing that connects to the mechanical equipment. It is usually located on the top, side, or near the output shaft of the housing, looking like a reflective silver metallic sticker.

Quick Search Tips:

  • Look for a reflective silver metallic card (or durable industrial sticker) usually printed with the NORD logo and a barcode/QR code.
  • Scan the flat, unobstructed surfaces on the outside of the gearbox (typically on the top, side, or near the output shaft area).
  • If the machine is covered in grease or dirt, use a flashlight to spot it easily.

Nameplate Fields and Their Meanings

  • Type / Model (e.g., SK 9032.1): The “floor plan” and series number of this reduction gearbox. It tells you how big the machine is and how much force it can handle.
  • Serial No. (Serial Number): The ID card of this machine (a unique number).
  • Ratio/i (Transmission Ratio, e.g., i = 25.43): How many revolutions the motor turns for every 1 revolution of the output shaft.
  • n2 (Output Speed, in rpm): How fast the gearbox finally outputs its rotation speed.
  • Torque / M2 (Output Torque, in Nm): How much “strength” the machine has.
  • Lubrication (Lubricant Information): Tells you what type of oil to add (e.g., ISO VG 220) and how many liters are needed.
  • Mounting Position: How the machine is positioned (e.g., M1, M2), which directly determines where the oil should be filled and how much is required.

If you only need to look at the 2 most critical data points on the entire nameplate for daily life:

  • Type (e.g., SK 9032.1): Represents its series and size, acting as the “ID/floor plan size” of the gearbox.
  • Serial No. (e.g., a long string of numbers): Whenever you want to buy accessories or contact manufacturer support, taking a photo of this serial number and sending it to NORD allows them to instantly pull up all factory archives for this machine.

How to Read a Nord Gearbox Nameplate？

During your daily work or maintenance, what exactly should you look at when you receive the nameplate? We have summarized the most crucial purposes into three key steps:

Step 1: Buy Spare Parts or Contact Support — Look for “Type” and “Serial Number”

If you need to purchase replacement parts from the manufacturer or consult technical support, never just report a general appearance. Write down the Type and Serial No. directly from the nameplate. With this serial number, NORD’s official team can pull up all original factory blueprints and configuration files from that year in a single second, ensuring that the parts you buy match 100%.

Step 2: Check Machine Performance — Look at “Ratio”, “Speed”, and “Torque”

If your equipment cannot handle the load or the speed is incorrect, compare it against the Ratio and n2 (output speed) on the nameplate. This helps you quickly judge whether the current workload exceeds the design limits of the machine, or ensures the correct parameters are chosen when buying a replacement unit.

Step 3: Daily Maintenance and Refueling — Look at “Mounting Position” and “Lubrication”

When it is time to change the oil for the gearbox, first look at the Mounting Position and Lub. (lubrication specifications) on the nameplate. Different placement orientations (such as horizontal vs. vertical mounting) require completely different fill port locations and oil volumes. Strictly following the oil grade and quantity marked on the nameplate prevents internal premature wear or overheating.

If you are looking to add oil, change oil, or inspect the machine, you only need to check these lines:

  • Ratio / i: e.g., i = 25.43.
  • Mounting Position
  • Lubrication
