G1-10
Concentricity Gage
The Universal Punch G1-10 is the smallest member of the G1-Series Side Checker family. Its defining architecture is the front carrier, which positions the indicator for side-oriented access while the workpiece is supported and rotated on precision rollers.
A small-part Side Checker with a distinct front-carrier architecture.
The Universal Punch G1-10 is a G1-Series Side Checker Concentricity Gage for the -10 part-size class. Published model data lists a part-diameter range of 1/8–1 in (3–25 mm), with workpiece length up to 4 in (102 mm).
The model name matters because Universal Punch concentricity gages are not separated by capacity alone. The G1 designation identifies the Side Checker / front-carrier measurement architecture, while -10 identifies the small-part size class. That distinction helps engineers and quality teams compare the G1-10 correctly against B-, E-, F-, and G2-Series systems that may share a similar dimensional envelope but use a different carrier or measurement arrangement.
In practical selection, the G1-10 should be evaluated when a small cylindrical part needs rotational inspection and the measurement feature is best accessed using the G1 front-carrier layout. The final system is then completed around the support lands, roller geometry, indicator position, stops, and accessories required by the actual part.
Start with the G1-10 when the workpiece is in the -10 size class and a Side Checker with front-mounted carrier access is more appropriate than a standard or vertical-carrier arrangement. Send Universal Punch the part print so the roller and indicator geometry can be confirmed before ordering.
Carrier architecture is the defining difference.
Several Universal Punch concentricity gages can cover small cylindrical parts. The G1-10 is not simply another 3–25 mm platform: it is the G1 Side Checker, defined by its front-carrier arrangement and the way that arrangement presents the indicator to the workpiece.
Published for parts from 1/8–1 in / 3–25 mm diameter and up to 4 in / 102 mm long.
The G1 family is specifically identified as a Side Checker architecture within the Universal Punch model system.
The front-carrier arrangement distinguishes G1 from the G2 Side Checker, which uses a vertical carrier.
Roller style, indicator access, stops, and optional accessories are selected from the actual inspection requirement.
G1-10 specifications at a glance.
The values below consolidate published Universal Punch model data and established G1-Series selection references. Capacity is a starting envelope, not a substitute for application review. Roller geometry, indicator access, support lands, and the inspection tolerance still determine the final configuration.
Gage model. Main rollers. Indicator & accessories.
The Universal Concentricity Gaging System is most useful when the configuration is broken into separate engineering decisions. The G1-10 establishes the platform and carrier architecture; the rollers establish how the part is supported; the indicator and accessories establish how the actual feature is observed.
Choose the G1-10 when the workpiece fits the -10 envelope and the G1 Side Checker / front-carrier arrangement matches the required indicator access.
Published -10 roller choices include Full Plain, Half Plain, Quarter Plain and Zero Style variants. Thin Zero rollers are also listed for applications requiring the smallest supported diameters.
Indicator style, carrier position, contact geometry, stops, fine adjustment, SPC requirements, and other accessories should be matched to the actual print and inspection workflow.
Common published choices include 110-10FP Full Plain, 110-10HP Half Plain, 110-10QP Quarter Plain, 110-10FZ Full Zero, 110-10HZ Half Zero, 110-10QZ Quarter Zero, and 110-10TZ Thin Zero roller sets. Final selection should be based on the actual support surfaces and part diameter.
Indicator selection is part of the system configuration and should be confirmed on the quote. If the inspection requires digital output, SPC compatibility, specialized contact geometry, or controlled rotation, specify that requirement when sending the application to Universal Punch.
Capacity tells you where to start. The print determines the setup.
A G1-10 selection should never be made from diameter alone. Universal Punch should understand where the part can be supported, where the indicator must contact, what feature is being evaluated, and what tolerance or runout requirement must be resolved.
That engineering discipline is what separates a model-selection page from a useful inspection system: the G1-10 defines the architecture, but the part defines the configuration.
Five disciplined views of the same G1-10 architecture.
The hero establishes the complete product. These four supporting views focus on the full profile, front/side carrier and indicator relationship, roller/support area, and rail/adjustment architecture without speculative diagrams or unnecessary callouts.
Similar size envelope. Different measurement architecture.
The G1-10, G2-10, and B-10 all address small cylindrical parts, which is why model names must be explained by architecture rather than diameter alone. The G1-10 uses the front-carrier Side Checker arrangement; G2-10 uses a vertical carrier; B-10 uses the Basic Extended / standard-carrier arrangement.
If you are unsure which architecture is correct, send the part drawing and measurement location. Universal Punch can determine whether front, vertical, or standard carrier access is the most practical approach before the gage is configured.
