Linear Bearings

Linear Bearing Products

Linear bearings, also referred to as linear bushings or linear bearing slides, are crucial components in linear motion systems.

They facilitate smooth and precise movement along a linear shaft by reducing friction and providing support to moving components.

Kiwi Motion offers a comprehensive range of linear bearings and shafts, designed to meet diverse application requirements.

Understanding Linear Bearing Types

Kiwi Motion provides various types of linear bushings, each with unique features and benefits:

Flanged and Flanged Long Linear Bushings

Features:

• Flanged Design: These linear motion bearings feature a flange that provides additional stability and guidance.
• Interchangeability: Designed to European standards, ensuring compatibility with other components.
• Low Friction: Engineered to minimise friction, allowing for smooth and efficient movement.
• Corrosion Resistance: Equipped with double rubber seals to protect against corrosion.
• Easy Mounting: Designed for easy installation and maintenance.

How They Work:

Flanged linear bushings consist of an outer sleeve with a flange and an inner sleeve containing ball bearings. The flange helps to guide the bearing along the shaft, while the ball bearings reduce friction and enable smooth linear motion. These bearings are typically mounted on a shaft using mounting holes or set screws.

Unflanged and Unflanged Long Linear Bushings

Features:

• Interchangeability: Designed to European standards for compatibility and interchangeability.
• Low Friction: Engineered to minimise friction, ensuring smooth and efficient movement.
• Corrosion Resistance: Equipped with double rubber seals to prevent corrosion.
• Easy Mounting: Designed for simple installation and minimal maintenance.

How They Work:

Unflanged linear bushings operate similarly to flanged types but do not feature a flange. Instead, they rely on the inner sleeve and ball bearings to guide and support the moving components along the shaft. These linear motion bearings offer flexibility in mounting options and are suitable for applications where a flange is not required.

Housed Standard and Long Linear Bushings

Features:

• Aluminium Housing: Housed bearings feature a rigid aluminium housing for enhanced stability and support.
• Interchangeability: Designed to European standards for compatibility and interchangeability.
• Self-Aligning: Housed bearings are self-aligning, allowing for optimal performance even in misaligned conditions.
• Low Friction: Engineered to minimize friction, ensuring smooth linear motion.
• Corrosion Resistance: Equipped with double rubber seals to protect against corrosion.
• Easy Mounting: Designed for easy installation and maintenance.

How They Work:

Housed linear bearings consist of a ball bearing assembly housed within a rigid aluminium housing. The housing provides support and stability, while the ball bearings facilitate smooth linear motion along the shaft. The self-aligning feature allows the bearing to adjust to misalignments, ensuring consistent performance.

Super Linear Bearings

Features:

• High Load Capacity: Super linear bushings offer three times the load rating of standard linear bearings, making them suitable for heavy-duty applications.
• Extended Life: These linear motion bearings provide 27 times longer travel life compared to standard linear bushings, ensuring durability and reliability.
• Silent Operation: Engineered for silent linear motion, ideal for noise-sensitive environments.
• Interchangeability: Designed to European standards for compatibility and interchangeability.
• Self-Aligning: Super linear bushings are self-aligning to 0.5 degrees, ensuring precise operation.
• Low Friction: Engineered to minimise friction, ensuring smooth and efficient movement.
• Corrosion Resistance: Equipped with double rubber seals to protect against corrosion.
• Easy Mounting: Designed for easy installation and minimal maintenance.

How They Work:

Super linear bushings feature an advanced design that allows them to withstand higher loads and provide extended travel life compared to standard linear bearings. They operate similarly to other linear bearings but are optimised for heavy-duty applications where reliability and durability are essential.

Linear motion bearing applications

Linear bushings find application across various industries and scenarios, including:

• CNC Machining: Linear bushings are integral components in CNC machines, providing smooth and precise movement for cutting, milling, and engraving operations.
• 3D Printing: Linear bushings play a crucial role in 3D printers, facilitating accurate movement of the print head along the X, Y, and Z axes to create intricate three-dimensional objects.
• Industrial Automation: Linear bearing slides are widely used in automated machinery and robotics for precise movement control in assembly lines, packaging systems, and material handling equipment.
• Medical Equipment: In medical devices such as diagnostic equipment and surgical robots, linear bushings ensure smooth and accurate movement, contributing to patient safety and treatment precision.
• Aerospace and Defence: Linear bushings are employed in aerospace applications such as aircraft seating systems, cargo handling equipment, and missile guidance systems, where precision and reliability are paramount.
• Automotive Manufacturing: In automotive production processes, Linear bearing slides are used in robotic welding systems, painting booths, and assembly line equipment to achieve consistent and accurate movement.
• Renewable Energy: Linear bushings support the movement of solar panels and wind turbine components, ensuring optimal positioning for maximum energy capture and efficiency.
