Manufacturer: Kyowa Kogyo Co., Ltd.
Model: SP Type

Features

The Standard (S) series provides excellent rotational accuracy and transmission capacity while maintaining minimal backlash.
It supports an inner diameter range of 3 to 50 mm and uses original dimension standards.
In addition, it offers a wide variety of standard options, including pin types, keyway types (new JIS and old JIS), and quick-change types, so it can meet diverse application needs.
Its compact design improves usability while maintaining high transmission capacity and functional performance.
The product achieves stable and superior rotational accuracy through a unique grinding process.
All major components use SCM415 material and undergo carburizing and quenching, so they ensure outstanding durability and long service life.
Overall, this spinning top joint balances accuracy, strength, durability, and cost, making it a highly reliable and well-rounded solution.
