ExpaTen Connecting Bolts for Ships Propellors
ExpaTen
The ideal connecting bolt
Free from backlash – Powerful – Reusable
SCHAAF is leading the way with ExpaTen bolts in order to revolutionize detachable flange connections of propulsion shafts of the shipbuilding industry. Not only are the bolts 100% non-positive and form fitting, which transfers high torque, but even after high stress they can be easily disassembled and reused. The bending and rotating resistant connection absorbed shock like changes of revolutions, torque as well as turning direction dependently. The system is made of heat treated steel, which is a safety plus during torque transfer. The safety factor in comparison to regular screws is 5. ExpaTen is easy to handle since all tools and hydraulic high-pressure pumps for assembly and disassembly are adjusted to the system. ExpaTen is certified by well-known buyers.
Advantages
SCHAAF is certified in accordance with
DIN EN ISO 9001:2000

Expansion and pretensioning result in the following advantages compared to conventional bolts:
High torque transmission, completely free from backlash
100 % positive locking and frictional connection
Torsionally and flexurally rigid connection even with sudden changes in the rotational speed, the torque, or direction of rotation
Reduction of flange dimensions possible due to fewer number of bolts for torque transmission
Maximum torque transmission in minimum space
More security
Simple and quick installation and removal of ExpaTen even after years of use and in restricted spaces
Reusable after removal
Cost-saving
Areas of Application
SCHAAF ExpaTen Bolts are the optimum solution wherever high forces (torques) must be transmitted and, at the same time, easy removal must be ensured.
Quality Assurance
All ExpaTen Bolts are checked for material quality, dimensional accuracy, correct functioning and load-resistance. During order execution, they are subject to continuous quality assurance measures and are supplied together with detailed technical documentation.
Services
ExpaTen Bolts are, of course, supplied packaged, ready for installation and use.
SCHAAF ExpaTen Bolts are user-friendly, reliable, and manufactured in accordance with the highest level of technical know-how. Our highly-motivated staff would be pleased to train your personnel, in situ or at our works, in mounting and dismantling the bolts.
