4 Point Principle

Our Wire Race Bearings are based on a simple yet ingenious principle: Individual race rings made of wire are fitted with a raceway that is designed precisely to match the diameter of the rolling elements. Therefore, the rolling action does not take place directly between the rolling elements and mating structure, but rather with low-friction on the four open race rings. This engineering principle permits free design of the mating structure in terms of its geometry and material selection.

Wire Race Bearings are extraordinarily compact and fit snug in even the tiniest mounting spaces. They are available either as bearing elements (consisting of race rings, rolling element and cage), or as ready-to-use bearing assemblies together with the mating structure.

Advantages

Maximum design freedom, without compromising precision or load capacity.

Principle

4 Point Contact

Freedom of Design

4 Point contact principle to take load from all directions. the rolling process does not take place directly between the rolling elements and the mating structure, but rather on special race rings, giving maximum freedom of design.

Compact

Minimal Mounting Space

Minimal Mounting Space

Requiring only a small mounting space, the compact and highly resilient four-point geometry of Franke Bearings gives you maximum freedom of design, making an ideal design component for your application.

Rotary Applications

CT Scanner
CT Scanner
Requirements
Element responsible for ensuring that precise images are delivered. Ability to run quietly and with low vibrations, even at high speeds. Guaranteeing exact radial and axial run-out.

Advantages
Extremely smooth running at up to 300 rpm. The elastomer suppresses the noise generation (60dBA). The bearing possesses a low rotational resistance (< 20Nm) and electrical insulation between the inner and outer ring. Loads in excess of 1000kg are possible.

Articulated Robot
Articulated Robot
Requirement
Lightweight robot used as a service and mobile robot. The net weight of 10kg with a rated load of 3kg. Franke Bearings were used in the movement axes, their main requirements were high stiffness, low weight and small mounting space.

Solution
Bearing elements in the LEZ64 and LEL84 series.

Satellite Antenna
Satellite Antenna
Requirements
A bearing weighing no more than 1kg. Smooth running with simultaneous tilting stiffness must be guaranteed.

Solution
LDB200 made from aluminium, with inner ring geared on the outside.

Advantages
Complete bearing assembly, ready for installation, made of aluminium and with tooth belt gear. Large open centre and low mounting space due to compact structure.

Circular Knitting Machine
Circular Knitting Machine
Requirements
The main bearing in the knitting machine plays a crucial role in the quality of the knitted goods. The highest standards are placed in the precision and operating performance of the bearing, despite the high mechanical and thermal load. The required speeds are up to 60 rpm.

Solution
A ground bearing element from the LEL series with a ball pitch diameter of 400 to 1500mm, made of chromium-silicon, ensures even, smooth running, even in the smallest mounting space. High precision of the bearing in axial and radial runout (<0.03mm) and the outstanding surface quality of the raceways ensure a constantly high quality of the machine.

Azimuth Bearings for Solar Panels
Azimuth Bearings for Solar Panels
Requirements
Bearing assembly to swivel the solar panel. Very slow-moving worm gear to follow the path of the sun. High stiffness to cope with any wind pressure.

Solution
The system uses wire diameters of 7mm and ball diameters of 20mm, to achieve the requisite load rating and stiffness. Other modifications: Special osculation and spherically seated design.

Advantages
Low mounting space thanks to direct integration in the cast housing of the rotary drive. High load rating and stiffness, also attractive series price and other advantages.

Satellite Antenna on Seagoing Vessels
Satellite Antenna on Seagoing Vessels
Requirements
A bearing which required high stiffness across its entire service life (shock stress due to waves and swell). The system needed to possess non-corrosive properties and provide constant rotational resistance across temperature ranges from –25°C to +60°C.

Solution
Bearing assembly LDA166 steel version, with adjusting ring, including coating and LER bearing element.

Advantages
Steel solution delivers constant rotational resistance across the entire temperature range. An additional inlet process with readjustment guarantees high stiffness over the whole service life.

Hubless Rim
Hubless Rim
Requirements
The aluminium-carbon rim on an electric race car should be designed to accommodate the drive and braking systems in its center. The bearings used must require very little mounting space and possess a large open center. Plus they need to securely transfer substantial forces and torques.

Solution
Integrated directly in the housing components of the rim as double row angular contact ball bearings. The Wire Race Bearing handles the prevalent loads and works independent of the material used in the mating components.

Advantages
LEL with wire diameter of 4mm, ball diameter of 3/8’’, 8, 10 or 12 mm. The carrying angle is 45°; in special cases even 53°, due to the mainly axial load. Standard speed are at 30 rpm, and up to 60 rpm for smaller ball pitch diameters The axial load caused by the machine cylinder is around 4000N, depending on the machine type.

Aerial Camera
Aerial Camera
Requirements
Light, customised bearings are required for the articulation of the cardanic suspension; they must possess high stiffness while at the same time remaining smooth and with low breakaway torque and rotational resistance. Forces and torques occur from all directions. The bearings must not impede the camera’s imaging quality.

Solution
LDB155 on high-strength aluminium with customized bore pattern. Anodized-orange by request of the customer.

Advantages
Bearing material, design and coating based on customer specifications. The 4-point contact bearing can accommodate forces from all directions and is insensitive to temperature fluctuation and vibrations. Smooth bearing with concomitant, high stiffness, at a favorable price.
