Screw Jacks
Bevel Gear Ball Screw Jack
Bevel gear ball screw jacks achieve fast travel speeds and are rated for near-continuous operation. Bevel gear high-speed screw jacks are precision screw jacks that use spiral bevel gear sets. These bevel gears are lapped together in pairs. High-quality alloy steel is used in their manufacture, and they are case-hardened. Robust rolling bearings support the input shaft and the lifting spindle axis giving long and trouble-free life.

Bevel gear ball screw jacks achieve fast travel speeds and are rated for near-continuous operation. Bevel gear high-speed screw jacks are precision screw jacks that use spiral bevel gear sets. These bevel gears are lapped together in pairs. High-quality alloy steel is used in their manufacture, and they are case-hardened. Robust rolling bearings support the input shaft and the lifting spindle axis giving long and trouble-free life. Bevel gear high-speed screw jacks provide a fast lifting speed with ball screws and trapezoidal spindles. Due to the high efficiency of the integral bevel gears, high overall efficiency is provided.

Best Materials
Raw materials decide the screw jack’s overall quality. At LiftingMotion, we use the best materials to guarantee the performance & lifetime of the ball bevel gear ball screw jack you purchased.
- Housing: Ductile iron housings. Compared with gray cast iron, it has higher plasticity and toughness, better mechanical properties, and its comprehensive properties are close to steel.
- Worm gear: ZQAl9-4 or ZCuSn10Pb1, high hardness, excellent wear resistance, not prone to seizure, good casting performance, and cutting performance.
- Worm shaft: 20CrMnTi, Surface carburizing and hardening treatment has good workability, small processing deformation, and fatigue resistance.
- Lifting Screw: C45, GCr15 or 316, 304. This series uses TBI-brand ball screws.
- Bearings: Tapered or ball thrust bearings, anti-friction, and provide rugged reliability.
- Grease lubrication. Offers easy maintenance.
