Engineered for high-torque requirements in Japanese machinery.
Japan’s industrial sector is renowned for its pursuit of "Monozukuri" (perfection in manufacturing). In the realm of hydraulic transmission, the transition from traditional linear cylinders to compact helical rotary actuators like the WL20 Series has become a defining trend. Whether it is for high-precision construction attachments or advanced material handling in the Port of Yokohama, the WL20 series offers the high-torque density required for Japan's space-constrained yet demanding environments.
The Japanese market is currently undergoing a massive wave of "Construction DX" (Digital Transformation) and automation. With a shrinking labor force, equipment must be more versatile and easier to maintain. The WL20 series, as a helical hydraulic rotary actuator, eliminates the need for complex external linkages and bearings, fitting perfectly into the modular design philosophy of modern Japanese OEMs like Komatsu, Hitachi, and Kobelco.
Japanese engineers demand zero internal leakage and precise positioning, a core strength of the WEITAI WL20 series.
With narrow streets in Tokyo and Kyoto, compact WL20 actuators enable machinery to operate in restricted spaces.
WL20 actuators are increasingly integrated with sensors for semi-autonomous hydraulic systems in Japan.
Entering the Japanese market requires more than just high-quality hardware; it requires adherence to local standards. Our factories ensure that all WL20 components can be adapted to JIS (Japanese Industrial Standards) regarding thread types (BSPT/JIS threads) and sealing materials that withstand Japan's diverse climate, from the sub-zero winters of Hokkaido to the humid summers of Kyushu.
As a leading mobile hydraulic supplier in China, WEITAI leverages a sophisticated supply chain that offers a strategic "Information Gain" to Japanese buyers. By sourcing from our ISO-certified factories, Japanese companies benefit from:
The WL20 uses multiple helical splines to convert linear piston motion into powerful rotation. This design provides significantly higher torque than standard cylinders.
Unlike competitors, our WL20 series integrates heavy-duty bearings that can handle high axial and radial loads, reducing the total bill of materials (BOM).
Ideal for Japanese "Mini" machinery, delivering up to 2700 Nm of torque in a footprint that is 50% smaller than traditional pivot systems.
Used in tilt-rotators for Hitachi excavators in Saitama infrastructure projects, allowing 180-degree tilting of buckets.
Ensuring the safety and stability of man-lifts used in Tokyo’s skyscraper maintenance.
Custom WL20 actuators for tunnel boring machines in Shinkansen expansion projects.
