Smoothy Screw
Outline
The smoothy screw is a high-efficiency screw that integrates the characteristics of a nut and ball screw.
The smoothy screw consists of 2 simple components, a nut made from PET (polyethylene terephthalate) and SUS (stainless steel) screw.
Features
- – High transmission efficiency (50%)
Higher efficiency than that of trapezoidal screws. - – Smooth operation without lubrication (oil, grease)
The new material nut ensures smooth operation without lubrication. - – Long operation life, low friction
The high-strength nuts are extremely durable and can be used safely for a long period of time. - – High quality
Able to deliver high-quality products due to processing, assembling, and inspecting our products in our quality-controlled factory.
