Features and Benefits:
Bolttech is known for solving the toughest bolting problems found in the industrial world today. These basic practices go into every design and manufacturing detail of our stud tensioning line of tools. We design our tensioners with quality, simplicity and versatility of the specific application and user in mind. Bolttech's Delta Series bolt tensioners maximize efficiency and minimize size for specific single stud size applications.
- Patented high pressure/low friction seals are designed to outlast the competition and provide accuracy within .5% with a calibrated pumping unit.
- Environmentally friendly, using water-filled tensioning systems.
- The direct axial load is applied to the bolt and inaccuracies created through friction are alleviated. |

In its standard range of hydraulic tensioners, SKF Equipements offers no less than 6 different types of tensioners with characteristics which are both different and complementary.
The product range includes multi- purpose, powerful, thin, compact and other types of tensioners, covering a wide range of bolt dimensions from M8 to M160 (5/16” to 6”), and able to apply pre-tightening loads ranging from 50 kN to 8500 kN.

The RotaBolt® range provides you with either finger-tip, visual or remote measurement of tension throughout the life of the bolted joint. They surpass traditional tightening methods such as:
- Hydraulic Tensioners
- Flogging
- Torque Systems
which have severe control limitations and can result in unpredictable bolt tension and joint failure.
RotaBolts are setting new safety standards in a wide variety of sectors where joints are subject to fatigue, vibration, pressure containment and structural slippage.

In some critical bolting applications, factors such as friction or bolt/joint geometry are such that the measurement of applied torque alone will not provide the degree of accuracy necessary to control the preload within the required limits. Likewise, many critical applications also demand that bolt preload be monitored over the service life of the fastener as part of a predictive or preventative maintenance program. In these applications, ultrasonic measurement of fastener elongation and/or load has frequently proven to be the most accurate, reliable and cost effective solution.
Ultrasonic measurement of bolt preload is made possible by introducing a sonic pulse at one end of the fastener and accurately measuring the time of flight (TOF) required for the echo to return from the opposite end; using material constants, the USM-II converts this TOF into an "ultrasonic length" of the fastener, providing a baseline from which future measurements will be made. When the fastener is tightened, the TOF increases and the USM-II will again utilize material constants to eliminate the effects of stress and temperature variations on sound velocity, providing an accurate elongation or load measurement.
The USM-II uses state of the art hardware and software to achieve these measurements with maximum automation, and minimizes the need for operator interpretation. Offering digital recordation and transmission of data, as well as calibrated analog signal output the USM-II provides a complete system for measurement, recordation, and control of fastener tension in the most demanding applications. |
