INKOMA JWH (High-Lead Ball Screw Type) offers significantly higher operational speeds, up to four times that of the JWB type, using the same input shaft rpm.
Features:
- High Operating Speed: The high-lead ball screw allows for a maximum screw shaft speed of up to 7.5 m/min, making it ideal for high-speed applications.
- Low Noise: Due to its design, it requires less input rpm for the same output speed as the JWB type, resulting in quieter operations.
- Primary Components: The jack features a high-lead ball screw and a precision worm gear for enhanced performance.
- Brake Requirement: As the high-lead ball screw lacks a self-locking feature, a brake unit is necessary for secure operation.
This model is designed for high-speed, quiet applications that require efficient and reliable performance.
