Frequently Asked Questions

Types of Linear Bearings We Stock

We stock a wide variety of Linear Bearings to suit different load capacities, space constraints, and precision requirements. Below is a breakdown of the types of Linear Bearings:

• Cam & Roller Followers - Designed to follow the cam lobe profiles or tracks, these bearings are ideal for high-load applications requiring accurate linear motion with minimal wear.
• Crossed Roller Bearings - Known for their high rigidity and compact size, these bearings are perfect for applications needing precise linear movement and limited space.
• Crossed Roller Way - Offering smooth and accurate linear motion, this system provides excellent rigidity and load-bearing capability in compact assemblies.
• Linear Bushings - Also known as linear ball bearings, these components are perfect for use with round shafts and provide smooth motion with low resistance.
• Linear Slide Units - Pre-assembled units that combine a linear bushing and housing, ideal for simplifying installation and ensuring precise alignment.
• MH High Rigidity Series - Designed for demanding applications, these linear bearings offer enhanced rigidity and strength, ideal for heavy-load and high-speed systems.
• ML Miniature Series - Compact and lightweight, these bearings are perfect for applications requiring small-scale components without sacrificing performance.

What is a Linear Bearing used for?

Linear bearings are designed to facilitate smooth, low-friction motion in a straight line. They’re commonly used in applications like CNC machines, 3D printers, robotics, and automation systems, where precision, speed, and stability are essential. By supporting the moving parts and guiding linear movement, they help improve accuracy and efficiency in machinery.

How do I choose the right linear bearing for my application?

Choosing the right linear bearing depends on several factors, including the load it needs to support, the required level of precision, environmental conditions and the available installation space. Be sure to consider whether your application needs high rigidity or compact dimensions. If you require expert help, contact the Quality Bearings Online team today.

What’s the difference between Linear Bushings and Linear Slide Units?

Linear Bushings are cylindrical bearings that slide along a shaft, offering smooth movement with low resistance. Linear Slide Units, on the other hand, are pre-assembled systems that include both a linear bushing and a housing. Slide units simplify installation and alignment, making them ideal for setups where consistent positioning and easy maintenance are important.

Do you offer bearings for high-speed or high-load applications?

Yes, we stock several options suited for demanding environments. Our MH High Rigidity Series and Crossed Roller Bearings are specifically designed for high-speed, high-load applications where stability and precision are critical. These bearings offer enhanced strength and durability, making them a top choice for industrial machinery and automation systems.

Can I order Linear Bearings in bulk or get custom recommendations?

We accommodate bulk orders for commercial and industrial clients and can provide tailored product recommendations based on your specific technical requirements. Whether you need a one-off replacement or a large volume for a production run, our team is here to ensure you get the right bearings quickly and efficiently. Contact us today for more information.
