GripCon

The optimum component connection
Cost reducing – Powerful – Unique

SCHAAF GripCon takes all of the leading design principles and advantages of ExpaTen and raises hydraulic coupling bolt design and performance levels to a new level. Designed for weight, cost and space saving applications, GripCon offers maximum product safety, cost saving, reliability and total performance for all power bolt connections. The patented SCHAAF design technology offers a complete lifetime guarantee even after a multiple installations and removals.

GripCon Formschlüssige Bauteilverbindung — Form fit component connection

which takes up highest axial and radial loads

SCHAAF GripCon Montagezylinder — SCHAAF GripCon mounting cylinder

GripCon Positionierring zum Festhalten der Konushülse — Positioning ring

for fixation of the Conical Sleeve while the Tapered Bolt is pulled into the Conical Sleeve. Expansion of the Conical Sleeve, gives a press fit and interlocking into the bore is the result.

GripCon Anschlussbohrung — Connecting bore

e for assembling and dismounting of GripCon

GripCon Gewährleistete Wiederverwendbarkeit nach Demontage — Guaranteed reusability

y when dismounted even after years of use. Again and again.

GripCon Druckverteilnuten auf der Kegelfläche — Pressure distribution grooves on tapered surface

for easy removal and installation even after years of service

GripCon Außenoberflächenstrukturierte Konushülse und Kegelbolzen — An internally Conical Sleeve and Tapered Bolt of high strength steel

for transmitting radial shear forces and high axial forces.

GripCon µ ≥ 0,9 Reibkoeffizient — µ ≥ 0,9 friction coefficient

between Conical Sleeve and bore wall.

Advantages

Due to expansion and interlocking of the sleeve into the bore surfaces, the following advantages are given compared to normal bolt connections:

No nuts for flange connections, thus significant cost reduction
An approximate 50 % weight reduction
Lower manufacture investment for significantly less connection elements
No more thread cutting in stud holes necessary
No protruding threads or nuts – better design and higher efficiency of rotation machines

More Advantages

No conventional bolt connection elements
Significant mounting time reduction because of less connection elements
Significant less mounting and dismounting space needed
100 % form fit and frictional connection anytime after mounting, no slipping of flanges
Simple and quick installation and removal of GripCon even after years of use
Reusability after removal again and again – no spare parts necessary

Versions

The standard version of the SCHAAF GripCon comprises the following components:

Tapered Bolt and Conical Sleeve of high-strength quenched and tempered steel for maximum shear strength and axial load capacity
Conical Sleeve with friction value maximised outer lateral area
Pressure connection bore and pressure distribution grooves on the taper for easy removal and mounting of the Tapered Bolt

Areas of Application

SCHAAF GripCon are the optimum solution wherever high forces (axial and radial) must be transmitted in smallest construction spaces and, at the same time, easy removal must be ensured, for example ship drive shafts, flywheel fixings for large motors, gear box manufacturing, heavy equipment manufacturing and wind power plants.

Quality Assurance

All GripCon 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

GripCon are, of course, supplied packaged, ready for installation and use. SCHAAF GripCon 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.
