THK Co., Ltd. (Minato-ku, Tokyo; President: Takafumi Teramachi; hereinafter, THK) is pleased to announce the commencement of orders for its fixed-side support unit 'FKT Series' for ball screws.
Ball Screw Support Unit 'FKT Series'
A support unit is a dedicated bearing component used in conjunction with a ball screw. The fixed-side support unit incorporates angular bearings, while the supported-side support unit uses deep groove ball bearings.
Conventional fixed-side support units used a 2-row configuration of angular bearings. In some operating conditions, such as when ball screws are used vertically, the load capacity could be insufficient, failing to meet required performance. The 'FKT Series' achieves stable durability even under high-load conditions by employing a 3-row configuration of angular bearings. This contributes to higher precision and longer service life for mechanical equipment, as well as improved design flexibility and easier product selection. A total of six model numbers, FKT10 to FKT30, will be offered to meet a wide range of needs.
Moving forward, THK will continue to develop and provide products that meet customer needs, leveraging the technology and expertise cultivated as a top manufacturer of linear motion guides.

Features
・High Axial Rigidity and High Load Performance
By distributing the applied load through a 3-row back-to-back arrangement, it enhances axial rigidity in one direction and exhibits high load performance.
・Optimal Bearing Adoption
Considering the rigidity balance with ball screws, angular bearings with high rigidity and low torque specifications are adopted.
・Compact and Easy Installation
It has a compact structure designed to accommodate installation space. Furthermore, since the bearings are incorporated with preload adjustment, they can be assembled as is, contributing to a reduction in assembly man-hours and an improvement in assembly precision.
[About THK Co., Ltd.]
Since its founding in 1971, THK has focused on developing various products as a creative and development-oriented company. In 1972, the following year, it commercialized the 'LM Guide (Linear Motion Guide),' which was the first in the world to achieve the 'rolling transformation' of linear motion parts in machinery. This dramatically improved the performance of mechatronic equipment such as machine tools. In recent years, it has been used in railway vehicles, medical equipment, high-rise buildings and residences, and amusement equipment, bringing various innovations worldwide.
