WESTport provides a full range of Spline Ring and Plug gages to meet your quality specifications. Company accreditations include ISO/IEC 17025, ISO 9001, compliancy to ISO 10012-1, ANSI/NCSLZ540-1 and former MIL-STD-45662A.

Spline gauges can be manufactured from 5mm up to 500mm. Spline gage profiles include involute, serration, and parallel (straight or helical). Full form go ring gages for checking major diameters, minor diameters, and tooth thickness.

Spline ring gauges (internal spline gauges) are used to check tooth thickness on an external spline component. Ring gauges can also be manufactured to fit new or existing taper master plug gauges (see taper master plug gauges for more information).

Western Pegasus offers a full line of spline ring and plug gauges. Spline ring and plug gauges provide the most basic and simple inspection of spline components. Go Composite Ring Gauges provide a basic check of the maximum effective tooth thickness of an external spline component.

Thread Check Inc. offers Go and No Go spline gauges that conform to ISO, DIN, AGMA, and JIS standards. Spline gauges can be manufactured from 5mm up to 500mm. Spline gauge profiles include involute, serration, and parallel (straight or helical).

EST designs and manufactures spline gauges for involute, serration and straight sided spline inspection and measurement requirements. We offer a wide variety of spline gages including: Go/No Go Functional Spline Gages; Helical plug and ring gages; Tooth thickness/space width variable gages; Measurement over/under balls (MOB or MUB) gages

STC manufacture Spline Ring Gauges as per various standards or customer requirement. These are the best inspection tools to check internal or external splined profiles for index and profile errors.

Jul 20, 2023 · Spline Ring Gages: Spline ring gauges check the splines on gears, shafts, and couplings. These gages have splines that match the part being inspected. This helps check that the splines are within the required limits. Spline ring gages come in go and no-go options, like threaded ring gages.

Variable Gauging (Spline Variable) is a segmented concept that is pre-set to a master plug or ring gauge and is designed to accurately measure the effective or actual tooth thickness or space width within 0.0001” (0.0025mm).

Mercury provides a full range of Spline Ring and Plug gauges in order to meet your quality specifications. Firstly, our gauges are hardened, then each is precision lapped and polished because superior accuracy, optimum gauge surface finish and longer wear life are essential.
