High precision ball bearings - Import export

Based on our many years of experience in developing and manufacturing high-quality machine components, GMN has specialized in the area of high-precision ball bearings as well as the production of high-performance and long-lived deep groove and spindle ball bearings to meet – or even exceed – the highest precision classes P4 and ABEC 7. Certification under international standards ensures the highest precision in the development and manufacturing of GMN ball bearings and guarantees constant, outstanding qualities related to speed suitability, stability and longevity. The broad product range includes a large selection of standard solutions as well as requirements-tailored special designs.

GMN offers a complete range of sizes, types and designs with its spindle ball bearings in standard sizes S, SM and KH. In conventionally oil-lubricated spindle bearings, lubricant is supplied through a lateral oil supply. GMN spindle bearing designs +A, +AB, +L and +LB provide direct oil supplies to the lubrication point through a bore in the outer ring. GMN spindle bearing designs +AG ensure the highest possible machine running times without complex oil supply systems. These feed the lubricant directly into the lubricating point through holes in the outer ring. The developed high-performance, separable BNT and BHT designs ensure fast and uncomplicated handling, especially with regard to assembly and maintenance.

The use of high-precision radial groove ball bearings is especially recommended when axial forces are supported in two directions, but the installation space makes the use of a spindle bearing pair impossible; plus when the best-possible guide for rotating components is needed, but the RPM requirements are less important. Depending upon the load capability and the installation space available, GMN provides deep groove ball bearings in sizes 60 and 62 as per DIN 625. A large selection of various cages, lubricants and covers make it possible to adapt GMN deep groove ball bearings to any application.

Compact Rail is a linear system consisting of steel linear rails with induction hardened raceways and high precision radial ball bearing sliders, also made of hardened steel. Thanks to their self-aligning capabilities, Compact Rail linear guides simplify the project, improve the performance and reduce the overall cost of application. Compact Rail linear guides are easy to install on all types of surfaces, including non-machined ones. Compact Rail linear guides feature a robust steel slider with ball bearings, self-centering heads with wipers, longitudinal seals to protect the internal components and a top sealing strip. The slider body is accurately finished with matte longitudinal edge chamfer and a shining ground flat surface. The slider heads are equipped with special slow release felt pads and are free to rotate with respect to the slider body, so that the felts are always in contact with the raceways to ensure optimal lubrication.

Silicon Nitride Ceramic Balls are widely used on bearings with extreme performance requirements, such as: High-speed bearings, high precision bearings, vacuum bearing, high / low-temperature bearing, non-magnetic bearing, high precision ball screw; it is also used as valve ball, measuring ball for the chemical pump, heat pumps, metering pumps. Its excellent properties including: Good corrosion resistance withstands attacks from harsh chemicals and environments. High-Temperature Hardness is twice that of steel, Silicon nitride ceramic balls retain their strength and hardness up to 1800 degrees F.Lightweight, silicon nitride ceramic balls’ density is 3.20g/cm3 and weighs 45% less than steel which reduces centrifugal force, skidding and wear under high speed and acceleration, so greatly extending the service life. Superior Surface Finish is conducive to improving working speed and reach higher accuracy.

Inspired by customer inquiries, SEPA EUROPE has developed a new, modular assembly for the efficient cooling of chips. The core component is a SEPA axial fan that is mounted on a 40 mm pure aluminium heat sink – a so-called Kühligel®. It is equipped with a finger guard and a double-sided adhesive heat pad for screwless mounting on the housing or inside the device. Thanks to the compact design, the light weight and the screwless mounting, this assembly enables accurate positioning and thus effective cooling of the hot spot. The chip cooler HXB40FGK is equipped with a high precision ball bearing and can be used at ambient temperatures between -10 and +85 °C thus opening up a wide range of application possibilities. A further advantage is the long service life of the fan with 350 000 h (MTBF) at 40°C. The chip cooler assembly HXB40FGK is supplied as a standard component. It can however, be customized.

All of our products fulfil the most stringent requirements of the standards that are in line with DIN and ISO. The high precision of our ball and roller bearings matches the characteristics of comparable world-renowned ball bearing brands. Ball bearings in almost any ranges can be quoted and delivered upon request. SLF can fit your bearing requirement needs with special material, special lubrication, special heat treatment, special backlash and higher levels of precision. We also produce high quality thin section bearings for the semiconductor, scientific and robotic industries. Our portfolio of services also includes the reconditioning of ball bearings.

Marteau & Lemarie ball specialists since 1922, selling all types of industrial balls on the market: Our company is renowned for the quality of its precision balls and also supplies polishing and grinding balls. Our different type of precision balls include: precision steel, stainless steel and plastic balls, and other precision balls (tungsten carbide, ceramic, glass, bronze and brass balls). Precision steel and stainless steel balls are defined by their nominal diameter, the raw material from which they are made and by their degree of precision. Grinding & polishing balls we stock mainly steel balls, stainless steel balls and glass balls. Our technical sales team is at your disposal for any further information and requests for quotes. So don't hesitate to contact us.
