TT Series – TTH-SA/CA
Low Profile Linear Ball Guides – Square Type
IMTEK TTH-SA/CA is a low profile square type linear ball guide from the TT Series, designed for compact machines that require smooth motion, reliable rigidity, and reduced installation height. With a four-row steel ball structure, wide rail design, and precision-ground raceways, the TTH-SA/CA series is ideal for semiconductor equipment, electronics assembly, medical instruments, inspection systems, and other high-precision automation applications. Available sizes include 15, 20, 25, 30, and 35, with rail lengths from 100 to 6000 mm.
- TTH series: -H means square type linear guide blocks
- Fixing method: -A means Locking from above
- Different length of linear bearing blocks:
–SA is for shorten length of linear guide blocks; –CA is for a normal length of linear guide blocks
If you are looking for a better performance on high temperature or rust corrosion resistance, IMTEK can give you further recommendation.

The reduced installation height helps engineers design smaller, lighter, and more space-efficient machines without sacrificing motion stability.
Square Block Structure for Stable Mounting
The square type carriage provides a stable mounting platform for automation modules, precision stages, tooling systems, and compact motion axes.
Four-row Ball Circulation for Smooth Motion
A four-row steel ball structure delivers smooth linear movement, balanced load distribution, and reliable performance in high-cycle automation environments.
Multiple Sizes and Material Options
TTH-SA/CA is available in sizes 15, 20, 25, 30, and 35, with alloy steel or stainless steel rail options to match different machine environments.
Suitable for OEM and Custom Machine Design
IMTEK supports OEM machine builders with flexible rail lengths, model selection support, and linear guide solutions for compact automation platforms.
Wide Rail Design for Improved Rigidity
The wide rail profile improves structural support and helps maintain motion accuracy under medium-load and offset-load conditions.
Semiconductor and Electronics Automation
TTH-SA/CA low profile linear guides are suitable for semiconductor handling systems, PCB assembly equipment, inspection modules, dispensing machines, and compact pick-and-place mechanisms.
The low installation height helps reduce equipment size, while the square block design provides stable mounting for precision motion modules. Smooth ball circulation supports repeatable movement in high-cycle production environments where stable positioning and compact machine layout are both important.
Recommended for:
– Semiconductor handling modules
– PCB assembly and inspection equipment
– Compact pick-and-place systems
– Dispensing and testing machines
– Electronics production automation
Precision Inspection and Measurement Systems
TTH-SA/CA linear guides are well suited for compact inspection and measurement systems that require smooth travel, stable support, and repeatable movement. The low profile structure allows engineers to design slim inspection axes while maintaining reliable carriage guidance.
Typical applications include optical inspection equipment, camera positioning modules, sensor adjustment stages, and precision measurement devices.
Medical and Laboratory Equipment
For medical instruments and laboratory automation systems, machine designers often need linear motion components that are compact, smooth, and reliable. TTH-SA/CA linear guides help support stable movement in limited-space equipment such as sample handling systems, diagnostic instruments, laboratory analyzers, and small precision stages.
Stainless steel rail options are available for applications that require better corrosion resistance or cleaner operating conditions.
Recommended for:
– Medical diagnostic equipment
– Laboratory automation systems
– Sample handling modules
– Small precision stages
– Compact testing instruments
Compact Automation and Small Machine Modules
TTH-SA/CA is a practical choice for compact automation axes, small CNC modules, light-duty machine tools, and custom motion platforms. The square block design offers convenient mounting, while the low profile rail helps reduce the overall machine height.
For OEM machine builders, the TT Series provides a flexible linear guide platform for designing compact, reliable, and cost-effective motion systems.
