IGUS

IGUS is a German manufacturer specializing in motion plastics, with a product portfolio centered on plain bearings, linear guides, cable carriers, and robotic systems. Founded in 1964 in Cologne, the company has developed a range of polymer-based components designed to operate without external lubrication, targeting applications where maintenance access is limited or where contamination from grease or oil must be avoided. The product families available through 3G Electric include sleeve bearings, flanged sleeve bearings, radial ball bearings, cable carrier mounting brackets, and collaborative robot arms. These components are engineered for use in industrial automation, packaging machinery, material handling, and other sectors where low friction, wear resistance, and corrosion resistance are required. IGUS bearings are typically made from engineered polymers such as iglidur, which offer self-lubricating properties and operate across a temperature range from -40°C to 80°C for standard variants, with some high-temperature grades extending to 200°C. The cable carrier systems, including the Series 15 mounting brackets, are constructed from Igumid TE, a reinforced polymer that provides mechanical stability and resistance to UV and chemicals. The IGUS Rebel cobot arm, with 4 degrees of freedom and a 3 kg payload, uses a BLDC rotary joint drive and the Igus Robot Control system, achieving a positioning accuracy of ±1 mm. 3G Electric stocks over 260 SKUs from IGUS, covering inch and metric sizes, with bore diameters from 3 mm to 1 inch and outer diameters up to 1.25 inches. The bearings are supplied in multi-packs for convenience, and the mounting brackets are available as sets with locking mechanisms for secure installation. All components are designed for dry operation, eliminating the need for lubricants and reducing maintenance intervals. The polymer construction also provides electrical insulation and resistance to moisture, making these parts suitable for cleanroom environments or food processing areas where washdowns are frequent. 3G Electric supports global procurement with detailed specifications, dimensional data, and part numbers for each SKU, enabling engineers to select components based on load, speed, and environmental conditions without relying on marketing claims.

Frequently asked questions

Common questions about IGUS from 3G Electric.

What materials are used in IGUS plain bearings?

IGUS plain bearings are made from engineered polymers, primarily from the iglidur family. These materials are self-lubricating, meaning they do not require external grease or oil. The specific polymer grade varies by application: for example, iglidur G is a general-purpose material for dry running, while iglidur J is optimized for low friction on soft shafts. The bearings are typically matte gray or dark red, depending on the series. The polymer construction provides corrosion resistance, electrical insulation, and operation in temperatures from -40°C to 80°C for standard grades.

Are IGUS cable carrier mounting brackets compatible with standard cable carriers?

Yes, the IGUS mounting bracket sets, such as the 1025-12PZ, are designed for standard cable carriers in Series 15. These brackets feature a zipper-style locking mechanism and are made from Igumid TE, a reinforced polymer. They accommodate one channel with a cavity height of 0.67 inches and a cavity width of 0.98 inches. The brackets are fixed-end types, meaning they attach to the stationary end of the cable carrier, and are available in black. They are sold as sets and include the necessary hardware for installation.

What is the maximum operating temperature for IGUS polymer ball bearings?

The IGUS polymer ball bearing model B623B1E, which is a 623-size open radial ball bearing, has a maximum operating temperature of 80°C. This temperature limit applies to the polymer ring and ball retainer. The bearing is designed for dry operation and does not require lubrication. For applications exceeding 80°C, IGUS offers high-temperature polymer grades that can withstand up to 200°C, but those are not included in the standard product range available through 3G Electric.

How does the IGUS Rebel cobot achieve positioning accuracy?

The IGUS Rebel cobot (model REBEL-4DOF-02) achieves a positioning accuracy of ±1 mm through its BLDC rotary joint drive system and the Igus Robot Control software. The drive system uses brushless DC motors with integrated encoders for feedback, while the control system manages trajectory planning and joint coordination. The cobot has 4 degrees of freedom, a maximum reach of 543 mm, and a payload capacity of 3 kg. The accuracy is specified for static positioning under rated load conditions.

Can IGUS sleeve bearings be used in washdown environments?

Yes, IGUS polymer sleeve bearings are suitable for washdown environments because they are corrosion-resistant and do not require lubrication. The polymer material does not rust or degrade when exposed to water, detergents, or steam. For example, the GSI-0708-08 and GFI-1011-08 bearings are dirt- and dust-resistant, making them appropriate for food processing or pharmaceutical applications where frequent cleaning is necessary. However, the maximum operating temperature of 80°C should be considered for hot water or steam cleaning cycles.

What sizes are available for IGUS low-friction sleeve bearings?

IGUS low-friction sleeve bearings, such as the RSI series, are available in inch sizes with bore diameters ranging from 3/16 inch to 1 inch. Outer diameters range from 5/16 inch to 1.25 inches, and overall lengths vary from 1/2 inch to 1 inch. These bearings are supplied in 5-packs and are dark red in color. The polymer material provides low friction coefficients against steel shafts, typically in the range of 0.08 to 0.15, depending on load and speed. Metric sizes are also available in other IGUS bearing families.
