miniature linear bearings

Deep groove ball bearing with seals or shields

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.Integral sea

Miniature linear bearings are precision components designed for applications where space is limited but high performance is required. These bearings are essential in various industries, including semiconductor, medical, surgical, robotics, and precision machinery, where compactness and reliability are critical. Here's a detailed introduction to miniature linear bearings:

What Are Miniature Linear Bearings?

Miniature linear bearings are small-scale linear bearings that facilitate precise linear motion in a straight line. They are designed to handle high accuracy requirements and repeatability, making them suitable for applications where components need to be moved along a defined path with minimal deviation.

Key Features of Miniature Linear Bearings

1. Small Size: Miniature linear bearings are available in sizes ranging from 1 to 25 mm, which makes them ideal for applications with space constraints.

2. High Load Capacity: Despite their small size, these bearings are designed to handle significant loads and are often preloaded to ensure optimal performance.

3. Low Maintenance: Many miniature linear bearings come with an integrated lubrication system that reduces the need for regular maintenance. For example, IKO's miniature linear guides use a built-in lubricating element called C-Lube, which provides long-lasting, maintenance-free operation through capillary action.

4. Corrosion Resistance: Miniature linear bearings are often made from materials that promote corrosion resistance, making them suitable for use in environments where exposure to moisture or corrosive substances is a concern.

5. Versatility: They are available in various styles, including double-row and four-row configurations, offering different load capacities and rigidity.

Types of Miniature Linear Bearings

• Double-Row Miniature Linear Ball Bearing and Guideway Assemblies: These units have two rows of rolling elements in four-point contact with the raceways, providing moderate load-carrying capacity and moderate to high torque load-carrying capacity.

• Four-Row Miniature Linear Ball Bearing and Guideway Assemblies: These are ready-to-fit guidance systems with high to very high load-carrying capacity and rigidity, suitable for unlimited stroke lengths.

Applications of Miniature Linear Bearings

Miniature linear bearings are used in a variety of applications where precise and controlled linear motion is required in a compact space, such as:

• Semiconductor Manufacturing: For wafer fabrication and other precision processes.

• Medical Equipment: In diagnostic procedures and surgical robotics.

• Robotics: In the joints and actuators of precision robots.

• Automated Manufacturing Systems: For conveyors and material handling systems.

Selection Considerations

When specifying miniature linear bearings, consider factors such as the bearing's width, length, inside diameter, dynamic load capacity, and the type of material used. The bearing housing can be flanged, none or open, rectangular, and pillow block, and the bearing may be open or closed.Features and options include adjustable preload, clean room use, lubrication port, recirculating bearings, self-aligning, vacuum compatible, and wipers or seals.

In summary, miniature linear bearings offer maximum performance in a small package, making them indispensable in industries where precision, reliability, and compact design are paramount.
