[IMG: Master Gears]

[H1] Master Gears
Spline Gauges Ltd is a world-leading manufacturer and supplier of high-precision master gears, renowned for our commitment to quality and reliability.
Our expert team and state-of-the-art equipment allow us to produce top-quality master gears quickly, satisfying the time constraints and demands of our global customer base.
[H2] Leading International Master Gear Manufacturer
Our expertise enables us to manufacture to a wide range of internationally recognised specifications (DIN, AGMA & ISO).
Master gears manufactured by Spline Gauges are trusted globally and across every industry—so much so that even our competitors turn to us for their gear needs!
[H2] Top Quality Master Gear Supplier
External and internal Master Gears are used for the composite checking of components. This is generally achieved by putting the master and component gears in hard mesh on a machine that records the deviation of centre distance during the rotation of the gears.
External master gears may also be used for evaluating a gear system for noise, vibration and harshness (NVH), known as single flank roll testing. Whereas internal master gears are used to verify the accuracy of internal gear teeth and ensure proper mesh and alignment.
[H2] Design & Quality
As a global master gear manufacturer and supplier, Spline Gauges Ltd specialises in manufacturing both internal and external master gears and we pride ourselves on our supreme quality.
We are also able to offer master gears in a wide range of internationally recognised standards to meet any customer requirements across the world, ranging from DIN 867 or ISO 53 standard 20⁰ pressure angle profiles to more complex asymmetric master gear tooth profiles.
[H2] DIN 867 and ISO 53
DIN 867 and ISO 53 provide guidelines for the basic rack tooth profile used in the manufacture of involute teeth on cylindrical gears. These standards define the fundamental geometry of the tooth form, including pressure angle, addendum, dedendum, and root clearance, ensuring consistent meshing characteristics and interchangeability between gears produced by different manufacturers. Compliance with DIN 867 and ISO 53 supports accurate gear generation, predictable load distribution, and reliable performance across a wide range of industrial applications.

[H2] External Master Gear Specifications

Applications
Master gears are utilized for composite checking of components, assessing total composite error, tooth-to-tooth error, runout, and functional tooth thickness. This process is typically carried out by tightly meshing the master gear with the component gear on a machine that measures the deviation in center distance as the gears rotate.

[H2] Spline Gauge Calibration & Gear Calibration – ISO/IEC 17025 UKAS Accredited Laboratory
Spline Gauges has an ISO/IEC 17025 UKAS laboratory where we issue certificates for both new and used gauges traceable to international standards. Our team are specialists in spline gauge calibration and gear calibration, providing this service to clients worldwide including our competitors!
At Spline Gauges, we have the capability to calibrate gauges, gears, and components, using various accredited methods. Our spline and gear inspection services ensure that all calibrated items meet precise specifications and international standards. To enable us to calibrate, we require a gauge, gear, or component drawing, spline or gear data, along with the standard or a previous inspection certificate. Click on the UKAS logo to view our schedule of accreditation.
Spline Gauges is fully committed to its customer support, and we will always look to provide re-calibration of any existing gauge in service, even from our competitors! Ask our sales team today for our calibration service charges by filling out the form.

[H2] Surface Superfinishing & Gear Polishing
Isotropic Superfinishing offers significant advantages in various applications like aerospace or motorsport. This treatment yields smoother gear surfaces, resulting in reduced friction, lower heat generation and decreased wear. Clients often request motorsport superfinishing and gear polishing due to the performance improvements it provides.
In the machining and grinding processes, machined parts often exhibit high and low areas, which are remnants of the manufacturing process. These elevated spots serve as initial contact points, potentially creating localized hotspots that can lead to failures. Isotropic Superfinishing also known as gear polishing effectively reduces the likelihood of such issues.
[H2] What are the key benefits of Isotropic Superfinishing?
One notable advantage of gear superfinishing is the elimination of stress risers at the edges of components, along with decreased friction on metal-to-metal interfaces. The superfinishing process eliminates the amorphous surface layer, extending the lifespan of parts by reducing wear and tear while improving sealing capabilities.
[H2] Motorsport Superfinishing
This process consistently delivers a uniform finish in all directions, ensuring repeatability and predictability. We incorporate this process into many of our Motorsport builds, given the compelling real-world results it delivers. If you prioritize reliability, strength, and performance, and seek a competitive edge, Isotropic Superfinishing is a must-have.
