Precision Linear Bearings for Industrial Applications
Linear Motion Bearings in Semiconductor Manufacturing

Semiconductor fabrication, testing, and inspection require ultra-precise motion components that operate reliably in cleanroom, vacuum, and high-temperature environments. Del-Tron provides linear ball slides and crossed roller slides engineered for exceptionally smooth, low-friction travel, as well as precision linear actuators capable of micron-level positioning. Our portfolio also includes some of the smallest linear slides in the industry, which are ideal for compact, high-density semiconductor tools where space and accuracy are critical.
Linear Motion Bearings in the 3D Printing Industry

3D printing has evolved from rapid prototyping to large-scale manufacturing, producing everything from automotive components to medical and dental prosthetics. These systems require motion components that deliver accuracy, repeatability, and smooth travel across X, Y, and Z axes. Del-Tron offers recirculating ball slide guides with travel ranges from 25 mm to 2 meters, along with lead screw actuators and ball screw actuators for motor-ready integration. Our linear ball slides and crossed roller slides are available in multiple precision grades and can be customized to meet the requirements of advanced additive manufacturing equipment.
Linear Motion Bearings for Defense and Aerospace Applications

Defense and aerospace systems demand motion components that deliver precision, durability, and reliability in mission-critical environments. Del-Tron manufactures linear slides, crossed roller bearings, and ball screw actuators engineered to meet the exacting standards of aircraft interiors, imaging and targeting systems, missile guidance, pilot helmet assemblies, and surveillance platforms. As a U.S. manufacturer, we provide a domestic supply chain for projects that require materials and manufacturing sourced within the United States, along with the capability to design custom solutions for specialized aerospace and defense applications.
Other markets we serve with our linear motion bearings include machine tool, factory automation, optical, laser, packaging, food processing, robotics, and test & measurement.
Frequently Asked Questions About Linear Motion Bearings
What are linear motion bearings?
Linear motion bearings use rolling elements to reduce friction and guide precise movement along a single axis. They are commonly integrated into OEM equipment for medical, aerospace, semiconductor, and factory automation applications.
What are precision linear bearings, and when should I use them?
Precision linear bearings are built for tighter tolerances, smoother travel, and higher repeatability than general-purpose bearings. Choose them when micron-level positioning, low friction, and long service life are required.
Is Del-Tron a linear motion manufacturer or a distributor?
Del-Tron is a U.S. linear motion manufacturer. We design and build linear motion bearings, slides, and actuators, and can customize solutions for your load, accuracy, and environmental needs.
How do I choose the right linear motion bearing for my application?
Match bearing type to load, stiffness, travel, and environment. Ball slides favor higher speeds. Crossed roller slides provide higher rigidity and load capacity. See our Product Selection Guide or contact us for assistance.
What’s the difference between linear ball slides and crossed roller slides?
Linear ball slides deliver low friction and higher speeds, while crossed roller slides offer superior rigidity and load capacity with exceptionally smooth, straight-line motion.
Are your linear motion bearings suitable for cleanroom or vacuum environments?
Yes. We offer stainless and low-outgassing options, non-magnetic variants, and lubricants compatible with cleanroom and vacuum use. Contact us for recommendations based on your process conditions.
Do you provide custom linear motion bearings or precision linear slides?
Yes. As a manufacturer, we can tailor linear motion bearings and precision linear slides to specific size, load, travel, and environmental requirements, including special materials and mounting patterns.
