About ITEM Roller Guide Track Rollers
The item product portfolio comprises more than 4000 high-quality components designed for use in machine bases, work benches, automation solutions and lean production applications.
After the usage of aluminium profiles in stationary designs, Linear slide elements were added to the product portfolio. Instead of being screwed into place, the steel shafts of these elements were pressed into the standard grooves of the profile. That was a brand new and low-cost solution - for guides of virtually any length. It also saved a great deal of assembly time. This modular linear guide system based on the Line 8 profiles of the MB system became the first in a long line of dynamic applications.

Outstanding Performance in Linear MotionDesigned to support and guide linear motion applications, the ITEM Roller Guide Track Rollers ensure smooth, stable, and precise movement along track systems. The combination of a single-row design, deep groove ball bearings, and pre-lubrication enables minimal friction while maintaining excellent load-bearing capabilities and extended service life.
Built for Durability and ResistanceManufactured from high-grade steel and surface-treated with zinc plating, these rollers are engineered to resist corrosion-even in more demanding conditions. Their heat-treated steel bushes and contact seals guard internal components, ensuring consistent performance in temperature ranges from -20C to +120C. This robust construction protects against premature wear and environmental impacts.
Versatile and Easy InstallationWith a bolt-on mounting type, these rollers are quick to install and suitable for a wide range of industrial setups, from factory automation to material transport. Their compact, precise dimensions and low-noise performance provide flexibility and comfort for integration within existing or new track systems, especially in German engineering environments.
FAQ's of ITEM Roller Guide Track Rollers:
Q: How do you install the ITEM Roller Guide Track Rollers in a linear motion track system?
A: Installation is straightforward with the bolt-on mounting type. Simply align the roller with the track, secure it using suitable bolts through the provided bore size of 12 mm, and ensure that the assembly is well-tightened to maintain smooth motion.
Q: What benefits does the zinc-plated surface treatment provide for the rollers?
A: The zinc-plated surface significantly enhances corrosion resistance, protecting the high-grade steel from rust and environmental wear. This extends the roller's lifespan, even in challenging industrial settings or humid environments.
Q: When is it necessary to replace the ITEM Roller Guide Track Rollers?
A: Replacement is recommended if you notice increased noise, diminished smoothness, or visible signs of wear after prolonged use. Even with pre-lubrication and high durability, inspecting the rollers as part of regular maintenance ensures continued optimal performance.
Q: Where are these rollers typically used, and can they operate in harsh conditions?
A: These rollers are extensively used in industrial machinery, conveyors, and automation systems that require precise linear guidance. Their temperature range from -20C to +120C, corrosion resistance, and sturdy construction enable reliable operation in both standard and harsh environments.
Q: What is the process for maintaining the pre-lubricated ITEM Roller Guide Track Rollers?
A: Routine maintenance mainly involves periodic inspections to check for debris or uncommon wear. Since the rollers are pre-lubricated and sealed, lubrication intervals can be extended, reducing downtime and maintenance requirements.
Q: How does the deep groove ball bearing type enhance roller performance?
A: Deep groove ball bearings offer low-friction, efficient high-speed rotation up to 8,000 RPM and support both radial and axial loads. This ensures quiet, steady operation and precise motion control-key for track systems needing dependable guidance.
Q: What are the main benefits of using a single-row precision track roller bearing structure?
A: A single-row bearing structure minimizes friction while delivering high load capacity (up to 750 kg) and excellent running accuracy. This design ensures a compact size and lightweight form (only 0.23 kg), optimizing efficiency for linear motion applications.
