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. |

| Kinney SDV Dry Screw suppliers of vacuum pumps operate without any sealing liquid in the pumping chamber. Without metal-to-metal contact inside the pumping chamber, wear is greatly reduced. |

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. |

Optimum contact ensured through the patented and renowned clamping yoke system which is based on the classical increase of force of the screw. Requring only small effort, the screw thread produces high contact power.
A high contact force is only effective when continuously excerted on the conductor. The Weidmüller clamping yoke system works as follows: When the clamping screw is tightened, the resultant force causes the upper thread overlap to spring open, thus causing a locking action to be exerted on the screw. Movement of the connected conductor is compensated by the elastic behaviour of the clamping yoke.
Result:
The connection is vibration-resistant and makes retightening of the clamping screw unnecessary. |

The screw connectors supplier are intended for stranded and solid aluminium and copper cables, carrying low and medium voltages of up to 36 kV. The range covers cross-sectional areas of 6-630 mm² for round cable and 25-300 mm² for sector cable.
Connection to the conductors is achieved by tightening the screws in the through connector or terminal to a predetermined torque. Tightening takes place into a partially threaded nut. The tightening torque is correct when the screw breaks at its notch. It does this thanks to an innovative double-ended shear-off screw, as shown in the illustration |
