Pacific Bearing delivers innovative products for Smooth & Quiet Linear Motion™, solving the toughest linear & rotary problems. Pioneering the first two-piece bonded Simplicity® linear bearing, we went on to create Dolphin Guides®, Mini Rail®, Redi-Rail® and Hevi-Rail® linear guides and linear bearing systems.
With a steel retainer and the right lubrication, chrome steel tiny bearings can be used in temperatures from 120°C to 150°C. However, chromium steel’s load capacity decreases at higher temperatures.
Chrome steel should not be used for small bearings in corrosive situations because chrome steel is not corrosion-resistant. Miniature bearings made of chrome steel are protected from moisture by a layer of preservative oil. It is not advised to use chrome steel bearings in a dry environment because they are prone to corrosion.
Condensation inside the protective packing may cause corrosion during storage or transportation. In addition, a dry bearing cannot have protective oil sprayed on its exterior since the protective oil would seep inside and render the bearing no longer "dry."
Most miniature bearings made of chrome steel can be delivered open or with metal shields. Manufacturers may offer larger sizes with low friction, non-contact rubber seals, or contact seals made of rubber.
Applications of Miniature Bearings
Small bearings are good for high-speed applications. These bearings provide modest performance levels regarding frictional torque, noise, and vibration. One may find small bearings in aerospace model drones, miniature motors, pan-tilt motors, dental drills, crushers, stepper motors, massage chairs, push rod motors, mechanical equipment, medical equipment, or precision instruments.
Tiny bearings can accommodate radial, thrust, and combination loads. They’re often used in tape recorders, precision instruments, domestic appliances, and fractional horsepower motors.
Many manufacturers offer miniature bearings for pulley, guide roller, and pinch roll applications with various bore diameters. Miniature bearings offer the benefits of low inertia, low torque, accurate running characteristics, and less wobble.
Benefits of Miniature Bearings
Miniature precise bearings help save space in semiconductors, medical instrumentation, and other equipment. They eliminate friction between pieces that must move independently. Bearings provide smooth inner and exterior surfaces for balls to roll against to reduce friction. These balls or rollers "transport" the weight so that the apparatus may spin smoothly. Thin and tiny ball bearings are widely used in robotics because of their design advantages.
Miniature bearings are lightweight and require very little storage space. They’re easy to install, assemble, or disassemble. A simplified production process makes bearings affordable. However, these small items have a powerful effect. Bearings can dampen vibrations to soften the sound of operating machines. In addition, they can support weight for a long time.
Challenges of Miniaturization
Miniature bearings are flexible but pose maintenance and flexibility issues; the smaller the bearing, the more vital it is to be aware of these issues. Miniature bearings require regular maintenance to ensure longevity and smooth performance. Regular lubrication or built-in bearing lubrication is crucial to ensuring this.
Additionally, the sizing and capacity options for miniature bearings are constrained, which poses a problem for higher-load projects. Make sure the necessary bearings or customization services are available if the application calls for various sizes or widths.
Depending on the design and use of the bearings, they may require additional cooling. Consistent lubrication is essential for keeping the bearings in good condition. Finding small bearing options may take time, making it difficult to finish a workable project.
Choosing the Correct Miniature Bearing Supplier
To make sure you have the most beneficial outcome when purchasing a miniature bearing from a miniature bearing supplier, it is important to compare at least four suppliers using our miniature bearing directory. Each miniature bearing supplier has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the supplier for more information or request a quote. Review each miniature-bearing company website using our proprietary website previewer to get an idea of what each business specializes in, and then use our simple RFQ form to contact multiple miniature-bearing companies with the same quote.

Linear Bearings Power Pages
Linear bearings are a type of bearing that "bear" or support the load of the carriage during its single-axis linear movement and provide a low friction sliding surface for the guide rails. In a linear guide, the carriage is the component that travels in a straight line, back and forth, along the length of the guide rail...
A linear actuator is a means for converting rotational motion into push or pull linear motion, which can be used for lifting, dropping, sliding, or tilting of machines or materials. They provide safe and clean...
Linear slides, also referred to as linear guides or linear-motion bearings, are types of bearings that allow smooth and near-frictionless motion in a single axis. Machine tools, robots, actuators, sensors, and other mechanical equipment often require moving components in a straight line in any of the three-dimensional axes...
Ball bearings are types of rolling-elements bearings that carry loads, reduce friction, and position moving machine parts while facilitating motion. They reduce surface contact and friction across moving planes by...
Ball screws are mechanical linear actuators that consist of a screw shaft and a nut that contain a ball that rolls between their matching helical grooves. The primary function of ball screws is to convert rotational motion to linear motion. Ball nuts are used in...
A lead screw is a kind of mechanical linear actuator that converts rotational motion into linear motion. Its operation relies on the sliding of the screw shaft and the nut threads with no ball bearings between them...
