Slim Bearings
Franke slim bearings deliver a convincingly smooth run, require an extremely compact mounting space and are simple to assemble. Slim bearings consist of one inner and one outer race ring with hardened and profiled raceways and a plastic cage with retained balls. The rolling elements touch the race rings at two points each, hence ensuring the 4-point system. The race rings are separated; their diameter can therefore be altered elastically for mounting.

Bearing Type
- 2 Race rings with profiled raceways
- Plastic cage with retained balls
- Franke slim bearings of type LSA deliver a convincingly smooth run, require extremely compact mounting space, ensure simple assembly and come at a favorable price.
Characteristics
- Simple, compact integration, LSA, infinitely variable Ø range
- Cost-effective alternative to standard slim bearings
- Not preloaded bearings
- Slim bearings type LSA consist of one inner and one outer race ring with hardened and profiled raceway and a plastic cage with retained balls. The rolling elements touch the race rings at two points each, hence ensuring the 4-point system. The race rings are separated; their diameter can therefore be altered elastically for mounting.
Diameter Range
- Infinitely variable from 4″ to 30″
Mating Structure
Slim bearings type LSA consist of one inner and one outer race ring with hardened and profiled raceway and a plastic cage with retained balls. The rolling elements touch the race rings at two points each, hence ensuring the 4-point system. The race rings are separated; their diameter can therefore be altered elastically for mounting.
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 ContactFreedom 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 SpaceMinimal 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.
