This is a sapphire ring gauge. It is a high-precision, high-hardness, and wear-resistant ring gauge.
This is a sapphire ring gauge developed in-house as an outer diameter verification gauge for optical communication-related products (ferrules, sleeves). Due to its material being single crystal sapphire, it offers excellent precision, is highly resistant to wear, and is a high-quality ring gauge.
Our motto is "Think of ways to do it before thinking of reasons why it can't be done."

We design and manufacture custom ring gauges.
Our company is a gauge and tool manufacturer. We can design and manufacture ring gauges based on your product drawings. Additionally, it is also possible to produce based on the drawings you provide. There are many examples of designing and manufacturing special ring gauges that cannot be obtained as standard products.
【Precision Measuring Gauge】 【Jig】 【Lap Processing】 *Various brochures are currently available*
【Precision Measurement Gauges】 We have been manufacturing custom-made gauges tailored to our customers' needs with micron-level precision. If you have concerns such as "the accuracy required by the customer is too strict to manufacture," "the measurement gauge currently in use wears out quickly and is problematic," or "we are unable to guarantee inspection accuracy with our measuring instruments," please feel free to consult with us. Additionally, we can accommodate standards that are stricter than JIS specifications. We will produce gauges tailored to your company's needs through made-to-order production. Since we have our own inspection facilities, we can ensure that the products meet the specifications before delivery, providing peace of mind. 【Jigs and Lap Processing】 Our company is capable of high-precision processing. In addition to the precision of machining, we utilize our unique technology of hand lap processing to achieve precision down to the micron level. We understand the customer's intent even in areas that are difficult to express in drawings, and with our inherent assembly adjustment skills, we perform final adjustments by hand to correct any misalignments down to the 1μ level during the assembly of parts.
Fast and high quality
Measurements are being taken in a 20°C constant temperature room. If you need something quickly or of high quality, please contact us. We will make every effort. An ISO traceability certificate is also available.
Master of small hole grinding technology Φ0.3 mm T3 mm
We respond to customer needs with the highest level of precision for all products. We guarantee this in a temperature-controlled room at 20°C or 23°C using sub-micron measuring instruments from Heidenhain, Johansson, Mobotireet, and others. We will do our best to meet your requests. Please let us know your desired delivery date. We will deliver in a very short timeframe. For more details, please contact us or refer to our catalog.
It has high precision, a tough and reliable structure, requires no maintenance, and has no running costs.
This is an electronic manual ring gauge with a built-in full bridge (LVDT) transducer that supports outer diameter measurements from 4 to 100 mm. It is ideal for measurement points close to the shoulder. It can be used to measure directly on the workpiece, or it can be used as a simple bench with optional support.
Making shaft measurement easier! Standard measurement from 5mm to 125mm, with the capability to measure larger diameters as well.
The "M4 Star MRG" is a mechanical ring gauge that measures shaft and pin-type components with diameters ranging from 5mm to 125mm using a dial indicator. The C dimension can be customized from 1mm to 6mm to allow measurement near the flange. For the 5-60mm range, it has one holding handle, and for the 60-120mm range, it has two small holding handles, making it easy to handle during measurement. It can also be mounted on a stand. 【Features】 ■ LVDT or HBT transducer ■ Standard measurement range from 5mm to 125mm, with the capability to measure larger diameters ■ Wireless or cable connection (cable outlet axial or radial) ■ Custom-designed: flexible customization options ■ Optional: gauge stand (with/without setting pin slot) *For more details, please refer to the PDF document or feel free to contact us.
A gauge with measuring end faces based on the maximum and minimum allowable dimensions of the axis.
We would like to introduce our "Limit Ring Gauge." This product is a type of through and stop gauge that has measuring end faces based on the maximum and minimum permissible dimensions of the shaft, in order to achieve compatibility for the fit between holes and shafts. Please feel free to contact us when you need assistance. 【Features】 ■ A type of through and stop gauge that has measuring end faces based on the maximum and minimum permissible dimensions of the shaft, in order to achieve compatibility for the fit between holes and shafts. *For more details, please refer to the PDF document or feel free to contact us.
It is possible to significantly reduce labor costs and equipment costs for in-house proofreading!
