Joyce/Dayton - Established 1873
Joyce Ball screw jacks feature a ball nut with integral ball bearings that recirculate along the surface of the manufacturer of ball screw. The significantly reduced friction between the ball nut and screw results in greater efficiency, with up to 2/3 less input torque required to move the load than a similarly rated machine screw jack.
Compared to Machine Screw jacks, Joyce Ball Screw Jacks
- Require less motor horsepower
- Allow higher travel speed
- Provide an extended duty cycle
Joyce Ball Screw Jacks are available in translating screw or rotating screw (keyed for traveling nut) designs. Translating screws are available with threaded, load pad, clevis or plain ends. Options include limit switches manufacturers, professional encoders, geared potentiometers, direct drive and reducer mounts, and protective professional boots. Joyce Ball Screw Jacks are ideal for single or multiple jack systems.
Unlike Machine Screw Jacks, Ball Screw Jacks are not self-locking. Because they will lower under load, a braking motor or other external braking mechanism is required.

| Roller screw jack provide higher performance compared to ball screw jacks. Ideally suited to applications where a high dynamic load, high accuracy, high speed and a long life are required. |

This unit is able to fulfil the highest requirements for a wide range of applications. By entering the load and output into your customer system, the air supply system automatically and directly adapts to the given requirements. The frequency-controlled drive unit offers a wide control range with optimised demand matching. In addition to energy savings and higher efficiency, this also results in lower maintenance requirements. The non-contact, oil-free screw unit ensures high air flows with low pulsation and lends itself to "master/slave" operation. Integrated accessories include a non-return cock, intake industrial filter, sound absorbers and ventilation/bleed system. An air blast industrial cooler is also available.

KRAL pumps with magnetic coupling are hermetically tight, the pump station as well as the site itself stays clean. As magnetic couplings work without wear and maintenance-free, the life cycle costs are favourable comparative to conventional sealing systems.
Please consider that we are a manufacturer of high quality displacement pumps and flowmeters for liquids. The products (pumps with magnetic couplings, high pressure flowmeters and flowmeters – chemically resistant) mentioned on this portal are only part of our product range. Please find more detailed information on our website or directly from us. |

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 manufacturer/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 professional 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 professional 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. |
