Heavy Load Linear Ball Guides - TO Series
TOW-CA/HA: Flange Type
TO series linear ball guides is a kind of linear guideway with heavy load capacity. It’s widely applied in CNC machine tools, grinding machine and some other automated machines. In general, IMTEK linear guide blocks are divided into flange type and square type. The flange linear bearing blocks have a low combined height and a large bearing area, which is suitable for the occasions that bear the load of the distance.
- Different linear guide block fixing method:
Lock from above(TOW-CA/HA);
Lock from below(TOW-CB/HB);
Lock from above or below(TOW-CC/HC). - Different length of TO series Flange type:
-CA/CB/CC for normal length
-HA/HB/HC for extra length of linear guide block. - Different materials of IMTEK linear ball guides:
-Alloy steel for normal series products.
-Stainless steel material, a new version for special application environment. - If you hope a better performance on rust corrosion resistance, please contact IMTEK for further recommendation about the stainless steel version linear guide rails and block.
How to Select Right Linear Guides for Applications?
Choosing a right linear guides system for your application, the precision, durability and cost-effectiveness are all quite essential problems. At IMTEK, complete catalogs and online product selector can help you make correct choices.
First, Define the Application Requirements
Start by clarifying the working conditions: load capacity, travel length, motion accuracy, and working environment. For example, linear guide rails and blocks for CNC machine demand high rigidity and precision, while those for 3D printer focus on compact size and smooth move.
No.2. Select Material & Structure of linear ball guides
Stainless steel version linear guides and carriages → Best for high corrosion resistance and cleanroom environments (e.g., food, medical, or semiconductor equipments).
Alloy steel linear guides → Superior hardness and wear resistance, ideal for heavy-duty automation.
Aluminum version → Lightweight and suitable for equipment requiring reduced mass.
(Tip: compare alloy steel vs stainless steel properties to match your priorities.)
No.3. Check Load & Accuracy Class Demonds
Use a linear guides load calculator or consult our engineers to determine proper size and preload. For heavy loads, roller linear guides are recommended while standard linear ball bearing are suitable for most industrial applications.
No4. Consider Installation & Dimensions
Confirm rail sizes, linear guide rail’s dimensions, and mounting method (top or bottom) to ensure compatibility with your machine base. Correct linear guide installation directly impacts long-term stability.
No.5. Lubrication & Maintenance of linear guides
Choose standard grease fittings or self-lubricating. Proper linear guide lubrication minimizes friction, reduces wear, and extends linear guides service life.
IMTEK can offer you expert consultation, CAD files, and a complete linear guide rail set for quick assembly. Our engineers provide tailored solutions, whether you need precision linear guides for robotics or curved linear guides for special applications.

Q: What is the smooth running characteristics of the linear ball bearing sliders source?
The linear slide rail has the ability to self-align.
The DF (45°-45°) combination from the arc groove is installed with the elastic deformation of the steel ball and the transfer of the contact point, even if the mounting surface is deviated, it can be absorbed by the linear rail slider, resulting in the effect of automatic centering ability and obtaining high-precision and stable smooth movement.
Moreover, the use of four-row circular arc groove, with the four-row steel ball and other 45 ° contact angle, so that the steel ball can achieve an ideal two-point contact structure, can bear the load from the up, down, left and right directions, and can improve the rigidity of the slide rail through preload adjustment, so as to achieve the requirements of high precision.
For the Ball type linear guide, because it is a precision inner design of point contact, the more point contact surfaces, the better when grinding.
Q: Is it feasible to utilize IMTEK linear guide in particular environment?
The standard applicable temperature is within -20 to 80 degree; we should be mindful of actual temperature in where we are and choose appropriate lubricant to fill. IMTEK can also offer you linear guides to special environment solutions. Please contact us for more details before your ordering.
