TZ Series - TZH-CA/HA
Roller Linear Guides – Square Type
TZ series roller linear guides use roller components, not steel balls in traditional linear motion parts, designed to achieve super-high rigidity and load capacity. Keeping the 45-degree contact angle design, TZ series linear guides show us a good performance in reducing elastic deformation. It allows the overall linear guide to achieve this high rigidity and high load capacity in multiple directions.
TZH-CA/HA model is a linear guide rail with square-type block, which has two lengths:
-CA for normal length and -HA for extra length of block.
They have different performances on load capacities and assembly space requirements.
Main features are as below:
- Customizable
- Ultra-high rigidity in all four directions
- Super heavy load capacity
- Extended life
- Durable
TZH-CA/HA
IMTEK Roller linear guides with rolling components can achieve smooth motion, low friction, and convenient maintenance for long-term service. What’s more, optimized lengths and diameters of the rollers are good at reducing elastic deformation and achieving super high rigidity.
TZH-CA/HA model is a linear guide rail with a square-type block, which has two lengths:
-CA for normal length and -HA for extra length of block. High-speed automated industrial machinery and equipment with high rigidity requirements are more likely to utilize TZ series Roller linear guides.

In these applications, TZ linear guides provide superior rigidity, high load capacity, and resistance to deformation, ensuring stable machining accuracy, smooth motion, and extended service life under demanding working conditions.


Q: Why are roller linear guides better for heavy-duty machining?
Roller-type linear guides provide line contact instead of point contact, which significantly increases contact area. This results in:
- Higher load capacity
- Improved stiffness
- Better resistance to deformation
This makes TZ series ideal for heavy cutting, mold machining, and large equipment.
Q: What is the main advantage of TZ series roller linear guides?
The main advantage of TZ Series roller linear guides is their high rigidity and load capacity. Compared with standard ball-type linear guides, the roller design provides line contact with the raceways, offering several practical benefits:
- Higher Load Capacity: Distributes heavy loads over a larger contact area.
- Greater Rigidity: Reduces elastic deformation under demanding operating conditions.
- Strong Moment Resistance: Supports pitch, yaw, and roll moments more effectively.
- Stable Machine Motion: Helps maintain positioning accuracy in CNC machines, gantry systems, and other heavy-duty equipment.
