In situations where stability is important, RK tube connectors require considerably fewer clamp connectors than simple sheet metal alternatives.

R28 Adapter Sleeve - New reducing bushes enhance flexibility and compatibility with tube connection systems

In industry, Lean applications like transport trolleys, in-line workstations and the like are often built on the basis of 28 mm tubes and corresponding sheet metal connectors. The new reduction sleeves from RK Rose+Krieger now allow these lightweight systems to be easily extended with the aluminium clamp connectors and tubes from the RK Rose+Krieger Solid Clamps system. The 28 adapter sleeve reduces the 30 mm internal diameter of the aluminium clamp to the standard 28 mm tube size. In this way, it allows for a direct connection between the two systems, giving the user greater freedom with regards to system design.



The adapter sleeve makes it easy to combine systems

The reducing bushes couldn't be easier to mount. They still, however, have a reliable axial and rotation locking feature.

Lightweight systems using sheet metal connectors are comparatively cheap and therefore widely available on the market. They are often suitable for applications where stability and load-bearing capacity requirements are not very high. In cases where such requirements are high, however, selective reinforcements are required at individual connections or entire constructions must be fitted with sturdier elements, like the modules available in the Solid Clamp system from RK Rose+Krieger. Up until now, it was not possible to combine the two systems. But thanks to the new adapter sleeves, users can now connect up 28 mm lightweight systems that use sheet metal connectors and Solid Clamps from RK Rose+Krieger. The reducing bushes are very easy to mount and have axial and rotation locking.
This alternative gives the user the benefit of the considerably greater variety that the Solid Clamps system from RK Rose+Krieger offers. More than 170 basic types are currently available in more than 400 different variations. The selection of variants, clamp diameters and range of combinations is vast.
RK Rose+Krieger developed the tube connector – made of cast aluminium or extruded aluminium – specially for the medium to heavy load range. These Solid Clamps not only offer variability but, above all, good mechanical properties and maximum value for money.

Although they cost slightly more than sheet metal connectors initially, they redeem themselves by being much easier to install and use comparatively fewer materials (fewer components to achieve the same stability). This saves you time and money in the long term.

Adapter sleeves for three diameter ranges

RK Rose+Krieger offers the new adapter sleeves for three diameter ranges, since the dimensions of 28 mm tubes can vary from one manufacturer to another:
  • Variant 1:    27.5 – 27.9 mm
  • Variant 2:    28.0 – 28.3 mm
  • Variant 3:    28.4 – 28.8 mm
