The INKOMA KSH Bevel Gear High-Speed Screw Jack is a modular system available in 3 sizes, each offering two gear ratios (2:1 and 3:1). These jacks are made with high-quality materials and are designed to deliver optimal performance in demanding lifting applications.
Features:
- Sizes: Available in 3 sizes with two gear ratios (2:1 and 3:1)
- Materials: Gear housings are made of GG 25 grey cast iron, and the bevel gears are manufactured from high-quality alloy steel, case-hardened for durability.
- Bevel Gear Design: Utilizes spiral bevel gears of Klingelnberg form, lapped together for precision, which contributes to high efficiency and smooth operation.
- Efficiency:
- Ball screw option: Up to 75% efficiency, with lifting speeds up to 30 m/min.
- Trapezoidal spindle option: Up to 40% efficiency, with lifting speeds up to 13.5 m/min.
- Durability: Robust rolling bearings support both the input shaft and lifting spindle, ensuring a long service life with minimal maintenance.
- Modular Design: All drive components are compatible with one another, allowing flexibility for a variety of applications.
Additional Information:
- Available with both rotating and translating spindle versions, and compatible with trapezoidal and ball screw spindles.
- Flanged nut dimensions conform to DIN 69051 standards for ball screws.
- Comprehensive range of accessories available to meet specific application requirements.
For any inquiries or specific design needs, customers are encouraged to consult INKOMA’s local sales office or factory engineers for expert advice and assistance.
