Bore Clamp

ROEMHELD RHI-S026 Bore Clamps eccentric design, seat check + clamping and unclamping monitoring, for bore holes

• Bore holes: Ø 8 – 12 mm,
• Double acting
• Max. operating pressure: 120 bar

ROEMHELD B1.480 pull-type, single and double acting, with anti-rotation device max. operating pressure 500 bar

• Maximum pulling force is 24.5 kN
• Single & double acting
• Clamping stroke, pulling - 6.0 mm
• Operating pressure 500 bar maximum

This Hydraulic Threaded-Body Clamping Module was designed for screwing in into standardized housings, fixture bodies or manifold blocks and fixture base plates or intermediate plates for pallets or machine tool tables. With single and double acting features and anti-torsion device.

ROEMHELD B1.481 Pull Type Double-Acting Bore Clamp with centering function, a compact design with high clamping force and repetitive clamping accurtacy of 0.005mm

• Bore diameter ranges from 16 to 46 mm
  
• Maximum low-clamping force ranges from 0.6 to 7.9 kN
  
• Admissible torque 15 - 300 Nm
  
• Double acting 

This Bore Clamp is a combination of a double acting pull-type cylinder equipped with a segement clamping bushing, which is pulled by a tie rod over a fixed cone. Thereby the segment clamping bushing expands radially to the bore diameter of the workpiece to be clamped.

ROEMHELD B1.4841 Bore Clamps: Block-type, without centring function, double acting, for bore diameter 7.8 - 17.7 mm, max. operating pressure 250 bar

OBSOLETE ITEM - CONTACT HYQUIP

• Double acting
• Operating pressure 250 bar maximum
• Bore hole diameter ranges from 7.8 to 17.7 mm
• Maximum low-clamping force 5.1 - 9.8 kN
• Expansion force , radial: 9 - 14 kN

This bore clamp is a double-acting pull-type cylinder. An exchangeable clamping bushing is fixed to the piston. The four segments of the clamping bushing are radially expanded with spring force by a pyramid-shaped clamping bolt. Thus the expansion force is always the same and independent of the hydraulic clamping pressure.

ROEMHELD B1.4842 Bore Clamps: Flange type, without centring function, double acting, for bore diameter 7.8 - 17.7 mm, max.operating pressure 250 bar

ROEMHELD B1.4843 Bore Clamps: Cartridge type, without centring function, double acting, for bore diameter 7.8 - 17.7 mm, max.operating pressure 250 bar

• Double acting
• Operating pressure 250 bar maximum
• Bore hole diameter ranges from 7.8 to 17.7 mm
• Maximum low-clamping force 5.1 - 9.8 kN
• Expansion force , radial: 9 - 14 kN

The four segments of the clamping bushing are radially expanded with spring force by a pyramid-shaped clamping bolt. Thus the expansion force is always the same and independent of the hydraulic clamping pressure.

ROEMHELD B1.485 Bore Clamp: Block-type eccentric, for bore diameter 6.6 to 13.8 mm, double acting, max. operating pressure 250 bar

• Double acting
• Operating pressure 250 bar maximum
• Clamping ranges from 6.6 to 13.8 mm
• Maximum pull force 3.8 - 6.3 kN
• Axial clamping force 210 - 720 N

In the body of the bore clamp a double-acting hydraulic cylinder is mounted. By screwing in the clamping screw the piston actuates via a dowel pin a drive pin that is eccentrically arranged at the edge of the housing. The clamping ring is centred on a taper sleeve and hold by the head of the clamping screw. The clamping screw is secured by means of a thread coating against loosening. Penetration of liquids and swarf is avoided by the connection of positive air pressure protection.
