Vacuum Filtration Device: This device performs precise filtration of cutting fluid used in machine tools by utilizing the negative pressure on the pump suction side. By maintaining the cleanliness of the cutting fluid, it extends its lifespan. It also offers benefits such as extending tool life and improving finishing accuracy. Managing contamination helps improve maintenance efficiency, such as preventing clogging in the machine's overall piping. Hybrid Cleaning Machine: This is a compact and precise cleaning device that combines cleaning, drying, and filtration of the cleaning solution.

This is an oil burner that uses kerosene and A heavy oil as fuel. It is portable and is used for drying and preheating ladles in casting equipment. It can be used anywhere as long as fuel and air pressure can be supplied, so if a portable pressurized tank is provided, it can be moved within the facility. Ignition is done using a spark or a torch burner, etc.

• Heating device

The German hydraulic equipment manufacturer Haiduck handles a wide range of hydraulic-related products, including filters, accumulators, measuring instruments, and heat exchangers.

• Hydraulic Equipment

The nitrogen gas generation device utilizes nitrogen present in the air to produce and supply high-purity nitrogen. Since it can be produced by ourselves when needed, it reduces costs and eliminates the hassle of management compared to purchasing in cylinders. The cold air generation device and jet cooler can generate air that is up to 40 to 60 degrees Celsius lower than the inlet air temperature without requiring power or operation by supplying compressed air.

• Pneumatic Equipment

Nihon Seiki is a comprehensive manufacturer of pneumatic equipment, handling pneumatic actuators, directional control valves, and circuit accessories. Additionally, they offer a lineup of distinctive products such as air dryers and high-performance air filters.

• Pneumatic Equipment

Azbil TACO is a manufacturer of pneumatic equipment such as valves, filters, regulators, lubricators, and lubrication devices for machine tools.

• Pneumatic Equipment

This is a maintenance-free oil-less bearing from Sankyo Oil-less Industries. Oil-less bearings are sliding bearings used in situations where oil lubrication is difficult or where there are impacts. They have self-lubricating properties, which prevent issues related to oil depletion. They provide excellent lubrication effects even under high load and low-speed sliding conditions, and can resolve problems such as seizure and galling.

• Metal bearings

The TAB series of bearings for ball screw support is designed to support ball screws used in various high-precision machine tools, precision measuring devices, and actuators for precision feeding, such as robots, with high precision and high speed. The retainers are made of resin, and by increasing the number of balls compared to conventional angular contact ball bearings, rigidity is enhanced. The combined bearings come with a predetermined preload, eliminating the need for complex assembly adjustments such as preload adjustment with shims or torque measurement. With a contact angle of 60 degrees, they can simultaneously and appropriately handle both radial loads and axial loads. As a result, the bearing section becomes simple and compact. The sealed types include both contact seals and non-contact seals, allowing for the selection of the appropriate type based on the application.

• Metal bearings

Various hydraulic valves are available in the hydraulic system, including high-pressure manual stop valves, electromagnetic switching stop valves, and maintenance valves.

• Hydraulic Equipment

A hydraulic servo valve is a valve that converts input analog or digital electrical signals into hydraulic control. It may be used when very precise control is required by feeding back information such as pressure, flow rate, and position.

• Hydraulic Equipment

The power package is a compact hydraulic unit that incorporates a gear pump, electric motor, tank, and valve. Depending on the type, there are versions that can be driven by DC power in addition to AC power, making it possible to integrate them into portable devices. The gear pump is made from aluminum alloy or cast iron and is small in size, suitable for a wide range of applications. Equivalent products to the discontinued old GP series produced by Nachi-Fujikoshi are also included in the lineup.

• Hydraulic Equipment

You can attach and detach without stopping the system, even under pressure. By adding test points to the valve and port, you can safely bleed air without oil leakage. Using the test point as the main valve for the pressure gauge reduces oil leakage to a minimum, decreases the labor involved in piping, and extends the lifespan of the pressure gauge.

• Hydraulic Equipment

When the liquid level in the tank fluctuates, such as during the operation of the actuator, outside air is usually drawn in and expelled through the air breather at the top of the tank. At this time, the contraction and expansion of the balloon adjust the fluctuation of the air inside the tank in response to the liquid level changes, preventing dust and other particles from the outside air from entering the tank.

• Hydraulic Equipment

Japan Pillow Block is a specialized manufacturer of pillow blocks (rolling bearing units and bearing units). We offer a wide range of products from standard items to those for special environments.

• Metal bearings

The pressure gauge is filled with glycerin, which provides durability. Various measuring instruments such as dampers for pressure gauges, gauge valves, switching valves, digital pressure switches, flow sensors, as well as high-pressure nylon hoses for pressure lines and check valves are also available. Gauge valves and check valves made of SUS for water use are also included in the lineup.

• Hydraulic Equipment

There are constant displacement types that discharge a constant flow rate depending on the rotation speed, as well as variable displacement types. There are also motor pump types that are integrated with a two-stage pump or electric motor. These are primarily relatively low-pressure pumps up to a pressure of 7 MPa.

• Positive Displacement Pump

OMRS (Osaka Magnet Roll) "magnetic separators and sorting machines" can remove iron pieces, fine iron powder, stainless steel abrasion powder, etc., from liquid and powder products. It can be modified to set up existing equipment or integrated into a unit. Products include magnetic separators, barrel separators, and conveying equipment.
