Product Description

 

OVERVIEW

SHAC linear ball screws

The Ball Screw is a high-efficiency method of converting rotary motion to linear motion by using a recirculating ball mechanism between the screw shaft and the nut. Compared with a conventional sliding screw, the ball screw requires driving torque of one-third or less, making it ideal for saving drive motor power.

 

SHAC designs and manufactures different series of ball screws suitable for various industries ranging from general machinery to CNC machinery, etc.

 

 

Main Series:
SFDC, DFDC,SFNU,DFNU,SFNI,DFNI,SFA,SFS,DFS,SFY,SFK,SCI.
Diameter from 6MM to 100MM with difference pitch,C3/C5/C7/C10 grade. 

Performance: Low noise, High precision, Good rigidity, Easily assembly, Long lifetime, Imported raw material.
Support to customize different length, special size screw nuts, OEM/ODM available.

High efficiencyWith the Ball Screw, balls roll between the screw shaft and the nut to achieve about 90% efficiency. Its required driving torque is only one third of the conventional sliding screw, and will generate little heat, so it's capable of high speed feed.High accuarcySHAC's screws and nuts are precision machined, assembled and inspected in a constant temperature workshop. The temperature and humidity are strictly controlled to ensure high precision and quality to be capable of micro feeding.High durabilityWe strictly control the design, materials and heat treatment, and use high-quality imported alloy steel and scientific heat treatment technology to give the screw and nut high rigidity, wear resistance and other mechanical properties to make the product more durable.

ABOUT SHAC

 

SHAC company development path

Founded in 2007, Lishui Yingte Bearing Co., Ltd. is a modern enterprise specializing in the research and development, manufacturing, sales, and after-sales service of linear transmission components, including linear guides, ball screws, and linear modules. In 2007, Yingte launched its first production line for ball screws and subsequently invested 16 million dollars to establish three modern production lines for rolled ball screws, ground ball screws, and precision ball screw nuts.

In 2011, the company expanded its R&D capabilities by establishing Taiwan Dinghan Transmission Technology Co., Ltd. in Taiwan.

By 2013, Yingte had invested an additional 21 million dollars to register Lishui Jiexiang Technology Co., Ltd. as a manufacturing base to enhance the production of linear guideways and blocks.

In 2016, Jiexiang was recognized as a national high-tech enterprise and adheres strictly to international standards such as ISO 9001 and ISO 14001, implementing rigorous control from raw material procurement to product sales to ensure the highest quality.

In 2020, Zhejiang Jianzhuang Transmission Technology Co., Ltd. was registered, and a second factory base, spanning approximately 65,000 square meters, commenced production. Yingte has built a regional direct sales network across over 30 domestic regions and established partnerships in more than 50 countries. To maintain product quality, Yingte has introduced and developed various testing equipment, including the Slider Finished Product Testing Line, Screw Lead Tester, Rockwell Hardness Tester, and Contour Graph, ensuring the delivery of high-quality products to customers and fostering stable development.
