Features of Ball Square Linear Guide Pair

Self-aligning capability

The circular-arc groove design with contact points at 45 degrees allows the ball square linear guide pair to absorb most installation errors due to surface irregularities. This enables smooth linear motion through the elastic deformation of rolling elements and the shift of contact points, providing self-aligning capability, high accuracy, and smooth operation with easy installation.

Interchangeability

The precision dimensional control of the ball square linear guide pair ensures that any blocks and rails within the series can be used together while maintaining dimensional tolerance. Additionally, a retainer is added to prevent the balls from falling out when the blocks are removed from the rail.

High rigidity in all four directions

The design of the ball square linear guide pair provides equal load ratings in the radial, reverse radial, and lateral directions. The circular arc groove allows for a wide-contact width between the balls and the groove raceway, enabling large permissible loads and high rigidity.

Applications of Ball Square Linear Guide Pair

Linear Actuators

Because of their ability to sustain moment loads, ball square linear guide pairs are frequently used as the guide mechanism for actuators driven by belts, screws, or pneumatic cylinders.

Overhead Transport Systems

Ball square linear guide pairs are ideal for guidance when loads are positioned directly below the rail and bearing block, which is often the scenario with overhead transport systems.

Gantry Robots

A gantry system features two X axes and sometimes two Y and two Z axes. Each axis typically operates via a screw or belt and pulley mechanism and is composed of a single ball square linear guide pair.

Linear Stages

Stages typically require high precision, so ensuring accurate travel and minimal deflection is essential.

Machine Tools

For high-quality production, machine tools, similar to stages, demand exceptional travel accuracy and rigidity. Deflection is reduced by employing two parallel rails, frequently equipped with two bearing blocks on each rail.

Precautions for Using Ball Square Linear Guide Pair

Ambient temperature control: The ambient temperature should not exceed 80°C, and the instantaneous temperature should not exceed 100°C.

Installation and removal of the slider: When removing or replacing the slider, a dummy rail should be used to assist in installation, and the guide rail should be avoided from being removed unless necessary.

Use in special environments‌: Special attention should be paid when using in special environments such as frequent vibration, high dust, high and low temperatures.

Lubrication and maintenance‌: Wipe the anti-rust oil first and then seal the lubricating oil for use to avoid mixing lubricating oils of different properties. When using lubricating oil for lubrication, adjust according to different installation methods. After filling the lubricant, push the slider back and forth for at least 3 slider lengths, repeat more than 2 times, and confirm that the oil film on the surface of the guide rail is uniform.

Storage and protection measures‌

When storing linear guides, make sure to apply anti-rust oil and seal them in the designated envelope, place them horizontally, and avoid high and low temperatures and humid environments.

Handling and protection‌

When carrying heavy linear guides, more than 2 people or use handling tools to avoid personal injury or damage to the workpiece.

Safety and protection precautions‌

The slider and guide rail may fall due to weight after tilting, so be careful. Avoid disassembling the slider by yourself to prevent foreign matter from entering or adversely affecting the assembly accuracy.

FAQ

Q: How does a linear guide work?

A: A linear guide is a machine element that utilizes bearings, which were developed for rotary motion, in order to move heavy objects easily in a straight line.

Q: What does linear guidance mean?

A: Linear guides provide a controlled and low-friction mechanism for heavy loads or objects to move straightly with high precision. The mechanism involves rolling balls as recirculating elements between rails and blocks, greatly enhancing the machinery's motion.

Q: What are the different types of linear guide rails?

A: When specifying linear guides for your applications, there are two types of guide rails from which to choose: square (profile) and round (shafting). Your application will dictate which types of linear guide rails should be used.

Q: What is the difference between linear guideways and box ways?

A: The key lies in choosing the configuration that best meets your machining needs: Box Way: Focuses on high rigidity, heavy cutting, and stability. Linear Guideway: Excels in high-speed machining and precise positioning.

Q: How much weight can linear rails hold?

A: Below are the features of heavy duty linear guide rails: High load capacity: Designed to support heavy objects, typically over 500 kg (1100 lbs). Durability: Made of strong materials such as hardened steel to withstand wear and tear.

Q: How to size linear bearings?

A: Generally you don't just choose a linear bearing by the dimensions of the bearing. When choosing a bearing size, you want to understand the loading capacity of the linear bearing block and linear rail system together. Size the bearing based on the load capacity and the required life span needed for your application.
