About NOGA

NOGA is a manufacturer of precision tooling and workholding accessories, with a product line that includes magnetic-base indicator holders, articulating arms, and centering tools. The brand is known for its modular indicator-holder systems, which are used in metalworking, machining, and quality-control environments to position dial and test indicators securely on ferrous surfaces. NOGA products are distributed globally, and 3G Electric supplies the line to industrial buyers who require repeatable measurement setups and durable workholding components.

The core of the NOGA offering is the magnetic-base indicator holder family. These units combine a magnetic base with an articulating arm, allowing the user to position an indicator at various angles and distances from the mounting surface. Many models feature a Fine Adjust Base (FAB) or Fine Adjust Top (FAT) mechanism, which provides controlled, incremental movement for precise contact with the workpiece. The magnetic bases are equipped with an On/Off knob, enabling the user to engage or disengage the magnetic force without moving the base. This is particularly useful when repositioning the holder or removing it after a measurement. Base dimensions vary across the range: compact models such as the LC6210 have a base measuring 30 mm W x 25 mm H, while larger units like the DG6160 and MG71003 have bases measuring 60 mm L x 50 mm W x 55 mm H. Thread sizes for indicator attachment include M5 and M8 x 1, accommodating a variety of indicator stems. Some models, such as the MG10533, have base dimensions of 2-23/64 in L x 1-31/32 in W x 2-5/32 in H, reflecting the inch-based sizing available in certain part numbers.

The articulating arm design allows the holder to be adjusted through multiple planes, which is essential when the measurement point is not directly accessible from the base location. The arm segments can be locked in place, providing a rigid setup that minimizes vibration and movement during measurement. This rigidity is critical for accurate readings, especially when using test indicators with low contact force. The Fine Adjust mechanisms—whether at the base or the top—allow the user to make small, controlled movements to bring the indicator stylus into contact with the feature being measured. This is often used in applications such as checking runout on shafts, verifying flatness on machined surfaces, or aligning workpieces on machine tables.

NOGA also produces centering tools and other accessories that complement the indicator-holder line. These tools are used in setup operations to locate the center of a bore or to align a workpiece with a machine spindle. While the sample products provided focus on magnetic-base indicator holders, the broader NOGA catalog includes a range of arms, clamps, and adapters that extend the functionality of the system. The modular nature of the products means that components can often be interchanged or combined to create custom setups.

3G Electric supports the NOGA line by stocking a selection of magnetic-base indicator holders and related accessories. The product data includes manufacturer part numbers, dimensions, thread sizes, and adjustment features, allowing buyers to match the holder to their specific indicator and application. For plant engineers and maintenance managers, this means access to components that are used in routine machine setup, preventive maintenance, and quality inspection. The holders are constructed from materials suitable for industrial environments, with magnetic bases designed to hold securely on ferrous surfaces. The On/Off knob feature reduces the risk of accidental movement when the magnetic force is disengaged, and the articulating arms are built to withstand repeated adjustments. 3G Electric provides global shipping and technical support for the NOGA range, with the ability to source specific part numbers and provide dimensional data for integration into existing measurement systems.

Common Applications

  • Machine tool setup — NOGA magnetic base indicator holders (e.g., MG10533) used to indicate workpiece alignment on milling machines and lathes.
  • Quality inspection — NOGA articulating arm holders with Fine Adjust Top (e.g., MA61003) for checking runout and flatness on machined parts.
  • Maintenance and repair — NOGA magnetic base holders (e.g., LC6210) for positioning indicators during shaft alignment and pump maintenance.
  • Toolroom and die maintenance — NOGA holders with Fine Adjust Base (e.g., NF1024) for precise measurement of dies and molds on surface plates.
  • Production floor — NOGA heavy-duty magnetic bases (e.g., DG6160) for holding indicators on large workpieces during in-process inspection.
  • Assembly and alignment — NOGA centering tools and indicator holders for aligning components on assembly fixtures and test stands.

Frequently asked questions

Common questions about NOGA from 3G Electric.

What is the difference between NOGA magnetic base indicator holders with Fine Adjust Top (FAT) and Fine Adjust Base (FAB)?

NOGA magnetic base indicator holders are available with either a Fine Adjust Top (FAT) or a Fine Adjust Base (FAB). The FAT mechanism is located at the top of the articulating arm, near the indicator attachment point, and allows for precise positioning of the indicator relative to the arm. The FAB mechanism is integrated into the magnetic base, providing fine adjustment at the base level. Some models, such as the NF6160, feature both FAT and FAB for maximum adjustability. The choice depends on the access and adjustment needs of the measurement setup. Both types include an On/Off knob for the magnetic base.

What thread sizes are available on NOGA magnetic base indicator holders?

NOGA magnetic base indicator holders use different thread sizes depending on the model. For example, the MG10533 and DG6160 feature an M8 x 1 thread, while the LC6210 and NF6160 use an M5 thread. The thread size determines which indicator stems or adapters can be attached directly. It is important to match the thread size to the indicator being used. Adapters may be available to convert between thread sizes, but the native thread is specified for each part number. Buyers should verify the thread size when selecting a holder for a specific indicator.

How do I choose the right size NOGA magnetic base for my application?

The size of the NOGA magnetic base affects holding force and stability. Smaller bases, such as the 30 mm W x 25 mm H base on the LC6210, are suitable for compact setups with light indicators and limited space. Larger bases, such as the 60 mm L x 50 mm W x 55 mm H base on the DG6160 and MG71003, provide greater holding force and are better for heavier indicators or setups where the arm is extended. The base dimensions also determine the footprint on the machine or surface. Consider the available space, the weight of the indicator, and the required reach when selecting the base size.

What does the On/Off knob do on a NOGA magnetic base indicator holder?

The On/Off knob on a NOGA magnetic base indicator holder controls the magnetic force of the base. When turned to the 'On' position, the magnet engages and holds the base securely to ferrous surfaces. When turned to 'Off', the magnetic force is disengaged, allowing the base to be repositioned or removed without sliding or scratching the surface. This feature is useful for quick setup changes and for protecting finished surfaces. It also reduces the effort required to remove the holder after measurement. The knob is typically a mechanical switch that rotates the internal magnet assembly.

Are NOGA magnetic base indicator holders suitable for use with test indicators?

Yes, NOGA magnetic base indicator holders are commonly used with both dial indicators and test indicators. The articulating arm and fine adjustment mechanisms allow for precise positioning of the indicator stylus against the workpiece. The rigidity of the arm and base helps maintain contact during measurement. Test indicators, which often have lower contact force, benefit from the fine adjustment to avoid over-travel. The thread sizes (M5 or M8 x 1) accommodate many standard indicator stems. However, users should verify that the indicator stem matches the holder thread or use an appropriate adapter.

What is the difference between the NOGA MG10533 and the NOGA MA61003?

The NOGA MG10533 and MA61003 are both magnetic base indicator holders with articulating arms, but they differ in adjustment features and dimensions. The MG10533 features a Fine Adjust Base (FAB) and has dimensions of 2-23/64 in L x 1-31/32 in W x 2-5/32 in H with an M8 x 1 thread. The MA61003 features a Fine Adjust Top (FAT) and has a magnetic base with an On/Off knob, though specific dimensions are not provided in the sample data. Both are part of the NOGA line and are used for mounting indicators on ferrous surfaces. The choice depends on whether fine adjustment is needed at the base or top.
