Introduction
A 1000mm linear rail is a precision mechanical component designed to provide smooth, rigid, and low-friction linear motion in automation and machinery. It typically consists of a hardened steel rail with a precision-ground raceway and a square-shaped block (the carriage) that houses recirculating ball bearings. This square profile offers high load capacity in all directions-radial, reverse radial, and lateral-ensuring exceptional stability and moment resistance. Square linear guides are fundamental in applications requiring high accuracy, repeatability, and the ability to handle heavy loads, such as in CNC machines, robotics, and industrial automation systems Products Description

Our Advantage
1)High Rigidity & Stability
The square shape can effectively resist the up and down, left and right moments and loads, prevent tilting, vibration or deformation in the process of operation, so as to ensure the extreme stability of the whole system under high speed and heavy load.
2)Excellent Load Capacity
Can withstand radial (down), reverse radial (up) and lateral (left and right) loads at the same time, with similar rated load capacity in each direction
3)High Precision & Smooth Motion
High positioning accuracy and repeated positioning accuracy: almost no gap in the movement to ensure the accuracy of the stop position.
Micro-scale operation: smooth movement even at very low speed, no "crawling" phenomenon, very suitable for precision machining and measurement applications.
Low friction and low wear: extends service life and reduces energy loss.
4)Long Service Life & High Reliability
High positioning accuracy and repeated positioning accuracy: The almost gap-free movement ensures the accuracy of the stop position.
Microscale operation: It can move smoothly even at very low speeds without "crawling", which is very suitable for precision machining and measurement applications.
Low friction and low wear:It extends the service life and reduces energy loss.
5)Long Service Life & High Reliability
The guide rail and slider are hardened to high hardness and wear resistance. The sealing system effectively prevents dust, chips and other contaminants from entering and maintains lubrication, thus ensuring long service life and reliable performance in harsh industrial environments.
6)Ease of Installation & Maintenance
Easy installation:Many brands provide matching reference planes to simplify leveling and alignment. Some models also come with reference edges for easy installation.
Keep it simple:Typically equipped with oil filling nozzle and high efficiency seals for easy re-lubrication and long maintenance intervals.
7)High Speed & Acceleration
Due to its low resistance characteristics, the drive system (such as a servo motor) can drive the load more efficiently, achieving faster high-speed reciprocating motion and shorter cycle times, significantly improving the production efficiency and throughput of the equipment.

FAQ
FAQ
Q1: What is the difference between square linear guide and circular shaft linear bearing? What are the main advantages?
A: Square linear guides excel in three key areas: exceptional rigidity, precision engineering, and load-bearing capacity. Their unique square-shaped structure combined with high-precision raceway design enables them to withstand loads and torques from all four directions-up, down, left, and right-delivering smoother operation and longer service life. In contrast, cylindrical linear bearings are typically used in applications requiring light loads, lower precision, short stroke movements, and cost-sensitive requirements.
Q2: How to choose the right rail size and model for my application?
A: The selection process is primarily based on four key parameters: Load: Calculate all loads including workbench weight, workpiece weight, and cutting forces, then determine their direction and magnitude. Precision Grade: Choose according to your equipment's positioning accuracy requirements (such as standard grade, advanced grade, precision grade, or ultra-precision grade). Operating Speed & Acceleration: High-speed applications require more stable structures and better dust-proof designs. Service Life: Use the service life calculation formula to estimate lifespan based on load and speed, ensuring compliance with equipment design specifications.
(Note: We recommend contacting our technical support engineers for free selection calculations and recommendations.)
Q3: What is prepress? Which prepress grade should I choose?
A: Prepressing is an internal load applied to the slider before leaving the factory to eliminate the gap between the ball and the raceway.
Light pre-press:Suitable for low vibration, low impact, smooth motion applications.
Intermediate prepress:Most commonly, a good balance is achieved between rigidity and smoothness of motion.
Heavy prepress:Suitable for high rigidity, high precision, heavy cutting force and vibration impact (such as machining center). Prepressing increases will increase rigidity, but also slightly increase friction and temperature rise.
Q4: What are the most important precautions when installing the guide rail?
A: The most critical aspect is ensuring proper parallelism of the two guide rails and flatness of the mounting base surface. Improper installation can lead to excessive wear, increased resistance, reduced precision, or even premature failure. Always use a torque wrench to tighten bolts according to the recommended torque and sequence. We provide detailed installation guidelines and instructional videos.
Q5: How to install and adjust the parallelism of multiple guides correctly?
A: The standard procedure involves using a leveled and tightened guide rail as the reference.A dial indicator is then applied to measure and adjust the second guide rail along its side surface until the reading variation across its entire length falls within the allowable tolerance range. Finally, all bolts are securely fastened.
Q6: After installation, the slider does not move smoothly or has a sense of sticking. What is the reason?
A: Potential causes include:
1.Parallelism deviation of the guide rail causing uneven internal force distribution in the slider;
2.Insufficient flatness of the mounting base surface leading to rail distortion after forced locking;
3.Impact damage to the guide rail or slider, resulting in roll raceway or ball surface indentations (contamination from debris may also contribute);
4. Incorrect bolt locking sequence or excessive torque application.
Q7: Do square linear guides need lubrication? What lubricant is recommended?
A: Yes, lubrication is essential! It reduces wear, lowers noise, prevents rust, and extends service life. Grease: The most commonly used option, easy to maintain, suitable for most applications. Oil: Ideal for high-speed operations, low-temperature environments, or friction-reducing needs. Select our recommended grease or oil models based on operating speed, temperature, and load conditions.
Q8: How often should lubrication be maintained?
A: The lubrication cycle depends on the operating conditions (speed, temperature, load, environment). The general recommendations are:
Initial lubrication:Fill the roller with grease before installation.
Supplementary lubrication:Replenish regularly according to operating time or mileage. In harsh environments (high dust, high temperature), shorten the lubrication cycle.
Q9: How to effectively prevent dust?
A: We provide a variety of grades of sealing end caps and oil scrapers:
Standard seal:Suitable for general industrial environment.
metal scraper:Suitable for heavy cutting, large amount of debris environment (such as machine tools).
labyrinth packing :Combined with magnetic sealing, it provides the highest level of protection and is suitable for extreme environments.
Q10: How to determine whether the guide rail or slider has been damaged and needs to be replaced?
A: The following signs usually indicate the end or damage of life:
The operational resistance has significantly increased, accompanied by severe jamming sensations. The clearance is excessively large, causing noticeable vibrations when manually pushing or pulling the slider. The precision has permanently deteriorated and cannot be restored through adjustment. Abnormal noises (such as sharp metal friction sounds and clamping noises) are present. Visible roller raceway indentations or peeling are observable on the exterior surface.
