RODOGRIP tapered shaft hubs: reliable and innovative solutions for gears and pulleys

11/06/2025

RODOGRIP is a line of keyless tapered shaft hubs designed for mounting gears and pulleys on shafts. Developed in collaboration with the Hungarian company Bervina Kft., these tapered shaft hubs provide an advanced solution that simplifies installation and ensures maximum reliability.

Perfect for a wide range of industrial applications, RODOGRIP shaft hubs offer precision, stability, and ease of installation. This line is based on the principle of frictional locking, which eliminates the need for the traditional keyway system. This approach reduces the risk of play between the parts and removes the need for specific machining on the shaft, simplifying installation and enabling faster, more precise assembly. Additionally, these bushings provide compactness, zero play, and low inertia, enhancing the overall performance of the assembly.

RODOGRIP® keyless shrink disk bushings are a simple and effective technical solution for solidly and reliably coupling shafts with sprockets or pulleys.
The principle is friction fit: there is no keyless shaft coupling, which is often the source of backlash, and therefore no need for specific machining or keyways on the shaft.
This technical solution brings many advantages:
● compactness
● small footprint
● easy installation, quick assembly
● simple, single-point clamping
● no backlash
● low mass and inertia
● excellent performance/cost ratio
● easy removal, no locking
● compatible with shafts with slots

  • The RTBS Series, made out of AISI 303 stainless steel, includes a range of standard sizes for shafts with diameters from 4 to 20 mm. The choice of stainless steel ensures corrosion resistance and long-lasting durability in challenging environments.
