Linear Bearing

Product Details:

A Linear Bearing Housing is an essential component that holds and supports the linear bearing, ensuring smooth and stable linear motion in machinery and equipment. It works in conjunction with linear bearings (such as ball or roller bearings) to allow for precise, low-friction movement along a straight path, often used in applications like CNC machines, automated systems, robotics, and linear motion systems.

Here’s an overview of the Linear Bearing Housing:

• The linear bearing housing serves as the framework or enclosure that holds the linear bearing in place. It supports the bearing while maintaining proper alignment between the bearing and the rail or guide, which is crucial for smooth motion.
• The housing ensures that the bearing remains stable and securely positioned, even when subjected to varying loads, forces, or vibrations during operation.

• Housing Shell: This is the outer casing or structure that surrounds the bearing. It is typically made of high-strength materials like aluminum, steel, or plastic to provide durability and support under load.
• Linear Bearing: The actual bearing that allows for smooth motion along a rail. This can be a ball bearing, roller bearing, or magnetic bearing, depending on the application.
• Mounting Holes: The housing will have mounting holes or brackets for securing the bearing system to the machine or equipment.
• Seals and Shields: Some linear bearing housings include seals or shields to protect the bearing from contaminants, like dust, dirt, or moisture, which could negatively impact performance or lead to premature wear.

Product Details:

A Housing Long Type Linear Bearing is a type of linear bearing that is designed to provide smooth, low-friction linear motion while offering a longer housing length compared to standard linear bearings. This extended housing provides additional stability and support, making it ideal for applications requiring higher precision, better load distribution, and more robust performance.

1. Longer Housing:

   • Extended Length: The housing is designed to be longer than traditional linear bearings, allowing for better support and stability over longer travel distances.
   • Improved Load Distribution: The extended housing helps evenly distribute the load across a larger area, which is beneficial for applications with high load demands or requiring longer travel paths.

2. Linear Motion:

   • These bearings enable smooth and precise linear movement, which is essential for applications that require accurate motion along a single axis, such as in CNC machines, 3D printers, and automation systems.

3. Low Friction:

   • The ball or roller type linear bearings inside the housing minimize friction, ensuring that the system operates smoothly and with less wear over time.
   • Pre-lubricated or Self-lubricating: Some models come pre-lubricated or have self-lubricating features, reducing the need for regular maintenance and improving the lifespan of the bearing.

4. Durability:

   • The materials used in the housing are typically made from high-strength aluminum or steel, offering excellent durability and resistance to wear and environmental factors like corrosion.
   • The housing also provides protection for the internal rolling elements (balls or rollers), preventing contamination and prolonging the bearing's lifespan.

5. Types of Rolling Elements:

   • Ball Type: Balls are used as the rolling elements inside the bearing. These provide smooth motion and are commonly used in applications where load capacity is moderate.
   • Roller Type: Rollers are used as rolling elements in some housing long type linear bearings. They offer higher load capacities than ball bearings and are suitable for heavy-duty applications.

6. Mounting and Installation:

   • The housing typically has holes or slots that allow easy mounting on a rail or another structural component.
   • These bearings are compatible with profile rails or round shafts, and they can be easily installed into various mechanical systems, allowing for simple integration into automation or motion control setups.

Product Details:

A Two Row Linear Ball Bearing is a type of bearing used to provide smooth linear motion in machinery and equipment, especially in applications where precise movement and high load capacities are required. Unlike traditional ball bearings, which typically operate in a rotational motion, a linear ball bearing allows for movement along a straight line (linear motion) while minimizing friction between the moving components.

1. Design:

   • As the name suggests, two rows of balls are arranged inside the bearing raceway.
   • The two rows of steel balls roll between the inner and outer races, allowing for smooth movement along the axis of the bearing.
   • The outer race is typically a cylindrical or rectangular shape, while the inner race is designed to fit onto a shaft or rail for linear motion.

2. Ball Arrangement:

   • The balls are arranged in two parallel rows within the bearing assembly.
   • The advantage of having two rows of balls is that it can handle higher loads and provide more stability in comparison to single-row bearings.

3. Load Capacity:

   • Due to the double row ball arrangement, these bearings can handle both radial (perpendicular to the axis) and axial (along the axis) loads simultaneously.
   • This design makes them ideal for applications where both types of loads are present.

A Standard LM Shaft refers to a linear motion shaft typically used in conjunction with linear bearings, such as LM (Linear Motion) Bearings. These shafts are part of linear motion systems that enable smooth, precise, and controlled movement along a linear path. LM shafts are commonly found in machinery, automation, robotics, and various industrial applications.

Here’s a more detailed breakdown of Standard LM Shafts:

• Material: Standard LM shafts are typically made from high-quality carbon steel, stainless steel, or alloy steel to provide durability, corrosion resistance, and long service life under mechanical stress.
• Surface Treatment: Often, these shafts undergo surface treatments like hard chrome plating or nitride coating to improve wear resistance, reduce friction, and protect against corrosion.
• Precision Ground: The shaft is precision ground to ensure smoothness and accuracy in linear motion. This is crucial for applications where precision is key.

• Standard Sizes: LM shafts come in various standard diameters and lengths. Common sizes include diameters from 6 mm to 50 mm, but custom sizes can be manufactured based on specific needs.
• Tolerances: The shafts are manufactured with tight tolerances to ensure minimal deviation, providing high precision and smooth movement when used with compatible linear motion bearings.

• Support for Linear Bearings: The primary function of an LM shaft is to serve as a guide for linear bearings (LM bearings). The bearings slide along the shaft, allowing for smooth and frictionless linear motion.
• Guide for Motion: LM shafts provide a linear track along which a load can move with minimal resistance and high stability, often used in X-Y tables, actuators, and other automated machinery.
