THK Linear Guide: Main Series Overview

/0 Comments/in /by

THK is one of the most recognized manufacturers of linear motion systems, and its linear guideways are widely used in CNC machines, industrial automation, semiconductor equipment, robotics, measuring instruments, and precision manufacturing systems. THK linear guides are designed to provide smooth, accurate, and low-friction linear movement while supporting high loads and maintaining long-term positioning accuracy. The main THK linear guide models can be grouped into several series according to structure, load capacity, accuracy, and application requirements.

One of the best-known THK series is the HRS series, which uses a compact ball guideway design for applications where installation space is limited. HRS linear guides are suitable for automation equipment, inspection machines, and other compact mechanisms that require reliable linear movement. Their relatively small size makes them a practical choice for lightweight and space-sensitive applications.

The HSR series is one of THK’s classic and widely used linear guide series. It features a four-way equal-load design, allowing the guideway to handle loads from radial, reverse radial, and lateral directions. HSR guides are available in many rail sizes and block configurations, making them suitable for CNC machine tools, industrial machinery, and general automation equipment. Common models include HSR15, HSR20, HSR25, HSR30, HSR35, and larger sizes.

For applications requiring higher rigidity and greater load capacity, the SHS series is another important THK product family. SHS linear guides feature a structure designed to provide high load capacity and good running accuracy while maintaining smooth motion. They are commonly used in machine tools, production equipment, and precision automation systems. Different block lengths and mounting configurations allow engineers to select the appropriate SHS model for their application.

The SSR series is designed for compact and lightweight linear motion systems. Compared with larger guideway series, SSR guides are especially suitable for equipment where installation space and moving mass must be minimized. They are frequently found in small automation systems, electronic manufacturing equipment, measuring devices, and precision mechanisms.

For extremely high-precision applications, THK also offers specialized series such as the SRG and SR series. These guides are designed for applications requiring high rigidity, excellent running accuracy, and stable performance under demanding operating conditions. They can be used in high-precision machine tools, semiconductor manufacturing equipment, and advanced positioning systems.

Another important category is the LM Guide series with Caged Ball technology, which helps reduce contact between rolling elements and can provide smoother operation, lower noise, and improved long-term performance. THK has developed several guideway structures using this technology for applications where operating stability and service life are particularly important.

If space is limited, the SNS-N compact type and HRW wide linear guide are good choices. HRW has a wide slider base, delivering strong anti-torsion performance without extra support structure, often used in single-axis moving platforms.

When selecting a THK linear guide, engineers should consider more than just the rail size. Important factors include load capacity, moment load, required accuracy, preload, block length, mounting dimensions, operating speed, environmental conditions, and available installation space**. For example, an HSR30 guide may be appropriate for a heavy-duty machine application, while an SSR15 may be better suited to a compact automation mechanism.

PMI linear guideways

PMI Linear Guideway Product Introduction

/in /by

PMI (Precision Motion Industries), established in 1990, is a Taiwan-based manufacturer of precision motion components. Its linear guideways are widely used in machine tools, industrial robots, semiconductor equipment, and automation systems, offering high precision, low friction, and long service life.

Core Technical Advantages

PMI linear guideways utilize a rolling motion design where steel balls circulate between the carriage and rail. This structure gives them significant advantages over traditional slide guides:

High Positioning Accuracy: With a friction coefficient of only 1/50 that of sliding guides, the difference between dynamic and static friction is minimal, eliminating stick-slip and enabling micron-level positioning accuracy.

Four-Directional Load Capacity: The 45° contact angle design of the ball grooves allows the guideway to bear loads in all four directions—radial, reverse radial, and two lateral directions—making it adaptable to complex load conditions.

Low Friction and Long Life: Friction resistance is only 1/20 to 1/40 of conventional slide systems. The design also incorporates a lubrication port on the carriage, simplifying maintenance and ensuring long-term accuracy retention.

Interchangeability and Easy Installation: Through strict manufacturing control, PMI carriages and rails within the same series are interchangeable. This allows replacement of individual components without complex scraping processes, significantly simplifying maintenance.

Thin section bearings

Thin section bearings introduction

/in /by

Thin section bearings, as the name implies, are a specialized class of rolling element bearings defined by a unique dimensional characteristic: a very small cross-sectional profile relative to their bore diameter. While a standard bearing’s cross section scales up significantly with a larger bore, a thin section bearing maintains an exceptionally slender and nearly constant cross section, regardless of whether the inner ring diameter is four inches or forty inches. This fundamental design principle unlocks a world of engineering possibilities, making them indispensable in applications where space, weight, and precision are paramount.

The defining feature of a thin section bearing is its square cross section. In these bearings, the radial cross section—the distance from the inner raceway to the outer raceway—is remarkably small and remains constant across a wide range of bore sizes. This is typically expressed as a series. For example, a bearing in the “KA” series may have a cross section of just 0.1875 inches, while a larger “KB” series is only 0.25 inches. This design yields a significant reduction in weight, often up to 85% less than a conventional bearing of comparable bore diameter. The reduced mass is not merely a shipping convenience; it translates directly to lower inertia, allowing for faster acceleration and deceleration in dynamic systems, which is critical for precision machinery.

Thin section bearings are available in three primary configurations: radial contact (deep groove), angular contact, and four-point contact. The radial contact type handles moderate radial loads and some thrust. The angular contact type is designed for combined loads, offering higher capacity in one direction. The four-point contact bearing is a versatile hybrid, capable of supporting radial, bidirectional thrust, and moment loads simultaneously, thanks to a single split inner raceway that contacts the balls at four points. This makes it an excellent, space-saving alternative to pairing two angular contact bearings.

Applications for these bearings are found where every millimeter matters. In robotic arms, they provide smooth, low-friction rotation for joints. In medical imaging equipment like CT scanners, their large, open bore and minimal cross section allow the heavy gantry to rotate precisely around a patient. Within astronomical observatories, thin section bearings support massive telescopes, enabling them to track celestial objects with minimal stiction. They are also crucial in semiconductor manufacturing, satellite mechanisms, and military turrets.

Areswin Precison Machinery Company can supply all kinds of thin section bearings with cheap price and good quality. The thin section bearing can replace with Kaydon thin section bearing.

Please contact us if you need thin section bearing:Inch Size Thin Section Open Bearings Supplier | Thin Section Bearings

In conclusion, the thin section bearing is a masterpiece of minimalist engineering. By decoupling the cross section from the bore diameter, it provides the robust, precise rotational support of a large bearing without the excessive weight and space penalty. For any design engineer tasked with creating compact, high-performance, and lightweight rotational systems, the thin section bearing is not just a component—it is an enabling technology.
