シールテック List of Products and Services

This is a mechanical seal type single passage rotary joint, primarily focused on examples of center-through coolant for machine tools, with a diverse track record in Japan. By selecting and designing the materials for the mechanical seal section, we can accommodate conditions that are difficult to meet with standard products. 【Features】 ■ Extensive track record in coolant transport applications for machine tools ■ Customizable options available ■ Many models capable of dry running ■ Models available that can simultaneously handle 20MPa coolant and dry air ■ Models available that can accommodate high flow rates of 100L/min coolant ■ Side-entry types available for cases where the shaft end cannot be used *For more details, please refer to the PDF document or feel free to contact us.

◆ Center Through Coolant Rotary Joint 'ROTODISK' - Compatible with high-speed spindles up to 42,000 min-1 - Supports high-pressure coolant at 20 MPa + dry air/dry run with the same unit - Capable of handling large flow coolant up to 120 ℓ/min ◆ High-Speed Rotary Table Rotary Joint 'ROTOSTAT' - Achieves low torque and long-term maintenance-free operation through "non-contact seal technology" - Provides a high-function model with a multi-port rotary joint including the spindle cooling circuit ◆ Composite Integrated Rotary Joint 'ROTOKOMBI' - Capable of simultaneous supply and discharge of different fluids - Integrated model available that combines a rotary joint with a slip ring for power and signal transmission *For more details, please refer to the PDF document or feel free to contact us.

This is a cartridge-type single-channel rotary joint developed for tool holders. It incorporates a small mechanical seal inside. By integrating it with the shaft and bore prepared by the customer, it enables fluid transport from the radial direction without using the shaft end. We offer various sizes, so please feel free to contact us. 【Features】 ■ Cartridge-type single-channel rotary joint ■ Achieves side entry of fluid without using the shaft end ■ Maximum operating pressure: 7 MPa ■ Maximum rotational speed: 6,000 rpm / 10,000 rpm (HM model)

"ROTOSTAT" is a rotary joint that employs a "non-contact (gap) seal." Since it adopts a non-contact method that automatically aligns under pressure, there is no wear on the contact parts. It can transport fluids maintenance-free for long periods, even under high pressure and high-speed rotation. It operates while slightly leaking liquid, so fluid recovery from the drain port is necessary. Customization is also available, so please feel free to consult us. 【Features】 ■ Usable for long periods of continuous operation ■ Compatible with various fluids such as oil, water, and air ■ Multi-port compatibility ■ Integration with other models is also possible *For more details, please refer to the PDF document or feel free to contact us.

Our company serves as the exclusive domestic agent for GAT, a German manufacturer specializing in rotary joints and slip rings, which are rare in Japan, providing a variety of products. We offer a range of rotary joints with diverse sealing methods and slip rings for power, analog signals, Ethernet, and video signals, and we can propose compact "integrated products" for robotic arms. If you are facing any of the following issues, please feel free to consult us! - "I want to send fluids or power/signals to the rotating part of a robot." - "I want to integrate the rotary joint and slip ring into a compact design." - "I am looking for low-torque rotary joints or slip rings." - "The robot moves quickly, causing hoses or cables to break." - "I am experiencing signal disruptions with Ethernet, leading to intermittent stops." 【Features】 - We can propose integrated rotary joints and slip rings. - Supports Ethernet (100BASE-TX/1000BASE-TX) and video signals up to 2.5 Gbit/s. - Hollow shapes can also be manufactured.

【Issues】 Conventional rotary joints use contact seals on the rotating axis, making it difficult to handle high PV (pressure-velocity) conditions. Additionally, they have the drawback of requiring maintenance, such as seal replacement, due to high rotational torque. 【Improvements and Effects】 This product is adopted for high-speed rotating tables and spindles in machine tools, achieving low rotational torque. 【Delivery Examples】 ■ Wind Turbines: For hydraulic blade pitch control ■ Machine Tools: For high-speed rotating tables and spindles ■ Testing Machines: For high-speed rotation *For more details, please refer to the PDF document.
