THK | Warehouse Automation

The rapid growth of e-commerce and the increasing pressure on supply chains to deliver faster and more accurately have made warehouse automation one of the most dynamic sectors in industrial technology. At the heart of automated storage and retrieval systems, conveying equipment, robotic picking systems, and sortation lines are linear motion components that must perform reliably through millions of cycles — often around the clock. THK's LM Guides, Ball Screws, and actuator units provide the durability, load capacity, and smooth operation that warehouse automation equipment demands, supporting both the high-speed throughput of modern fulfillment operations and the positional accuracy needed for reliable item handling. THK components are designed to perform in the varied environmental conditions found in warehouse and distribution center environments — from temperature-controlled cold storage to large-scale ambient facilities — while minimizing maintenance requirements and maximizing uptime. As warehouse operators continue to invest in automation to meet growing demand and address labor challenges, THK's proven motion technology provides the reliable foundation that keeps these systems running at the speed and efficiency that today's supply chains require.

Ball Spline

The Ball Spline is a rolling guide spline bearing. This is an innovative product with a ball rolling on a groove connected to the shaft, realizing allowable loads greater than with linear bushing and enabling torque transmission while making linear movements.

Cam Follower

The Cam Follower is a compact bearing with a high-rigidity shaft and a built-in needle bearing. Most suitable as a guide roller for cam mechanisms and linear motion of automated machines and dedicated machines.

Cross Roller Ring

With the Cross-Roller Ring, cylindrical rollers are arranged crosswise, with each roller perpendicular to the adjacent roller, in a 90゜V groove, separated from each other by a spacer retainer. This design allows just single bearing to receive loads in all directions including, radial, axial and moment loads. Since the Cross-Roller Ring achieves high rigidity despite the minimum possible dimensions of the inner and outer rings, it is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machines.

Linear Actuators

Actuators simplify the design and construction of systems by combining separate components, including Linear Motion Guides, drive system (ball screw, belt, or rack & pinion), and base frame, into one part.
This simplification results in a very compact design as well as significant cost savings. Actuators are a very easy way to quickly build up multi-axis systems, streamlining design time, and allowing to focus on performance instead of implementation.

Linear Motion Guide

The LM Guide (Linear Motion Guide) is our main product, incorporating a part with a linear rolling motion into practical usage for the first time in the world. It realizes the development of high-precision, high-rigidity, energy-saving, high-speed machines with long service lives.

Lubrication

An assortment of lubrication associated products is available to maintain sufficient lubrication of machines.

Roller Follower

The Roller Follower is a compact and highly rigid bearing system. It contains needle bearings and is used as a guide roller for cam discs and straight motion. Since its outer ring rotates while keeping direct contact with the mating surface, this product is thickwalled and designed to bear an impact load.
