... the standards for tool making, mould making, construction 

of jigs and fixtures and production 

Cost consciousness! 

A high quality level and mature technology at affordable prices. The basic 

product for your daily clamping tasks. Your safety: Absolute reliability thanks 

to mechanical-hydraulic power transmission, well-proven in practice. 

Your added value: Can be used together with the well-known HILMA 

interchangeable jaws and the extensive range of accessories. 

Versatile and flexible! 

The classic unit for high demands on quality and flexibility. Well-proven 

power transmission either mechanical-hydraulic or hydraulic for automation. 

Your benefit: The keyways and hole pattern are arranged for accommodating 

step jaws for extra large clamping ranges. Keyways across the width for 

rapid positioning on the machine platen. Can be used with the well-known 

HILMA interchangeable jaws and the extensive range of accessories. 

For the most exacting demands! 

Our premium product for even greater quality, process safety and precision. 

The benefits: Large capacity although with a compact overall length. 

Encapsulated power transmission system, base free from deformation, very 

precise linear guide and much more. Compatible with commercially available 

zero point clamping systems. Existing clamps from the HILMA range can 

be used. All this makes your investment sound for the future. 

Accessories and jaws 

Simply economical! 

An extensive range of quickly interchangeable jaws and convenient 

accessories guarantee exact positioning and clamping of both simple and 

complex workpieces. This significantly enlarges the possible range of uses 

of the clamping element. In many cases, the need for special fixtures can 

be dispensed with. 

Made by HILMA 

Efficient and cost reducing! 

A patented technique for cost-effective manufacture of 2, or optionally 

4 workpieces makes this product a unique means of cost reduction in the 

manufacture of small, medium and large batches. Compact overall 

dimensions, linear guide without play, one-side spindle operation and the 

3 rd hand function are further important advantages. Mechanical and hydraulic 

designs available. 

Light-weight and flexible! 

The standard fixture for a large number of workpieces with complex clamping 

contours, e.g. formed parts. Easy milling of stop, clamping and contact 

surfaces in aluminium jaws. 

Rapid change from one workpiece to another. Aluminium body with hardened 

steel guides ensures a low weight. In many cases, the need for special 

fixtures can be dispensed with.

The optional selection of clamping force (retrofitting possible) enables

Special benefits by the possibility of exact positioning on all machine beds 

provided with grooves as well as optimum use of the machine travel and

For tool making, mould making, construction of jigs and fixtures and production 

This new development meets the most exacting demands on clamping quality. The mechanical-hydraulic power 

transmission and the spindle drive are integrated into the slide body and are fully encapsulated. Easy, user-friendly 

manual clamping using the crank handle. 6-stage clamping force selection and angular drive are available as optional 

extras which may be retrofitted. The non deformable steel base with hardened and ground guideways and the linear 

guide with almost no play guarantee maximum precision.

This is the device we offer for clamping workpieces with complex clamping and contact 

contours. In many cases, expensive special clamping fixtures are no longer required. 

Instead of a complete new fixture just a new set of jaws may be used! 

The aluminium jaws can be completely milled out to suit the required workpiece contour. 

This gives the fastest jaw change without a screwed connection! The aluminium base with 

hardened steel guides results in a low dead weight. The third hand function ensures 

consecutive safe loading and unloading of workpieces.

PROGRESS BY INNOVATION 

For the pioneering idea of using mechanical-hydraulic 

power transmission HILMA was awarded, in 1949, patent 

no. 970520. This was the beginning of the era of power-assisted 

machine vices around the world. Since that time, our products 

have undergone continuous development. 

Today, HILMA is a leading manufacturer of clamping 

systems for machine tools, machining centres, flexible 

production systems and press automation. As a member 

of the Roemheld Group, we make use of numerous 

synergies, as a globally orientated enterprise we are an 

internationally renowned partner for innovative clamping 

technology. 

The consistently high quality of our products, in accordance 

with a quality control system as per DIN ISO 9001, as well as 

highly motivated and efficient staff are the solid basis to 

set standards in the field of clamping technology by 

innovative, creative development which will continue in 

the future.
