Preload values vary by model, with some single bearings rated to 330 N and others to 1,300 N. GMN labyrinth seals are non-contact seals for rotating shafts, available in various inside and outside diameters and body widths. These seals protect bearings in pumps, gearboxes, electric motors, and other rotating equipment. Some variants include a drain groove, while others do not. 3G Electric supplies GMN bearings and seals as part of its industrial equipment portfolio. The product line includes multiple SKUs, such as the KH 6009 matched duplex bearing, the KH 6008 single bearing, the S 6009 and S 6210 bearings, and labyrinth seals like L200X230X20, L90X110X10, L20X28X10, and L20X30X10. These components are used in applications where precision, speed, and reliability are critical. 3G Electric provides logistics support for worldwide delivery and can assist with product selection and quoting. The company serves plant engineers, maintenance managers, and procurement specialists who require technical specifications and availability information. GMN products are manufactured to standards including ABMA, DIN 628-6, and ISO, ensuring interchangeability and performance consistency. The bearings are suitable for machine tool spindles, robotics, instrumentation, and high-speed rotating equipment. The seals are used in pumps, gearboxes, and electric motors to protect bearings from contamination and extend service life. 3G Electric maintains inventory of these GMN components and can source additional items as needed. For technical buyers, the key specifications include bore diameter, outside diameter, contact angle, closure type, cage material, preload, and precision rating. These parameters determine the suitability of each component for a given application. GMN's product documentation provides detailed dimensional and performance data, which 3G Electric can supply upon request. The company's focus on precision engineering makes its components suitable for demanding industrial environments. 3G Electric's role is to make these components accessible to a global customer base, with efficient order processing and shipping. Whether you need a single bearing for a repair or a matched pair for a spindle rebuild, 3G Electric can provide the GMN part you require. The product range is continuously updated, and 3G Electric's catalog reflects current availability. For specific part numbers or technical questions, contact 3G Electric's support team.

Frequently asked questions

Common questions about GMN from 3G Electric.

What are the key specifications of GMN high-precision angular contact bearings?

GMN angular contact bearings are available in metric sizes with contact angles of 17° or 25°. They are rated to ABEC P4 precision and come in single or matched duplex configurations. Closures include open and double-sealed (2RZ) designs, and cages are phenolic. Preload values vary by model, with some single bearings rated to 330 N and others to 1,300 N. They meet standards including ABMA, DIN 628-6, and ISO. Typical applications include machine tool spindles, robotics, and instrumentation.

What sizes of GMN labyrinth seals does 3G Electric supply?

3G Electric supplies GMN labyrinth seals in various sizes, including inside diameters from 20 mm to 200 mm and outside diameters from 28 mm to 230 mm. Body widths range from 10 mm to 20 mm. Examples include L20X28X10, L20X30X10, L90X110X10, and L200X230X20. These non-contact seals are used to protect bearings in pumps, gearboxes, electric motors, and other rotating equipment. Some variants include a drain groove, while others do not. 3G Electric can source additional sizes as needed.

How do I select the right GMN bearing for my application?

Selection depends on factors such as bore diameter, contact angle, closure type, cage material, preload, and precision rating. For high-speed applications, a 17° contact angle may be suitable, while 25° offers higher axial load capacity. Matched duplex pairs provide minimal runout and are used in spindle applications. Open bearings allow for higher speeds but require lubrication, while double-sealed bearings offer protection against contaminants. Consider the operating environment and load conditions. 3G Electric can provide technical data and assist with selection.

What are the benefits of GMN labyrinth seals?

GMN labyrinth seals are non-contact, meaning they do not wear against the shaft, reducing friction and heat generation. They protect bearings from dust, dirt, and moisture in rotating equipment such as pumps, gearboxes, and electric motors. The labyrinth design creates a tortuous path that restricts contaminant ingress. They are available in various sizes and with or without drain grooves. These seals help extend bearing service life and reduce maintenance requirements. 3G Electric supplies these seals for a range of shaft diameters.

Does 3G Electric provide worldwide shipping for GMN products?

Yes, 3G Electric offers logistics support for worldwide delivery of GMN bearings and seals.
