- Providing the latest sealing system for hydraulic cylinders from Hallite! The slipper seals, which combine high-quality Armorlene high-performance PTFE and engineering plastic seal rings and O-rings like HLX, offer low friction with no stick-slip and enable high-speed strokes. They are compatible with standard ISO7425-2 grooves and come in a wide range of options in both metric and inch sizes. 【Features】 ■ Low starting friction resistance ■ Design that suppresses stick-slip occurrence ■ Excellent dynamic and static sealing properties ■ Long lifespan with excellent extrusion resistance ■ Absorbs shock loads from pressure spikes 【Operating Conditions】 ■ Maximum speed: 15.0 m/sec ■ Temperature range: -45 to 200℃ ■ Maximum pressure: 60 MPa ■ Buffer seal/pressure spike: 80 MPa Hallite is a group company of Michelin. M.O. Tech Co., Ltd., a specialized trading company for sealing systems, is the only officially certified distributor of Hallite in Japan.

Proposal for a state-of-the-art sealing system to address the main challenges of V-packings. [Main Challenges] - There are instances of replacing V-packings with other types, leading to discontinuation without updating molds, making them increasingly difficult to obtain. - Lubrication is hard to reach throughout the entire V-packing, resulting in increased friction due to lack of lubrication, which leads to shaft wear. - Stick-slip is likely to occur during startup and at low speeds. - Stick-slip makes precise positioning accuracy difficult, resulting in vibrations and noise. - The design requires a large amount of space. *These main challenges can be resolved.
