Sterilizable Motors EC 13 and EC Size 5

Small, precise and extremely fast! Maxon presents the sterilizable 50 Watt drives “EC Size 5” and “EC 13” For the use in high speed medical applications of up to 90’000 rpm. Stand-alone, or as motor/gear combination, the drives stand out by high power, extremely low-noise and low-vibration operation, marginal heat generation and minimal size – welcome characteristics particularly in medical handheld power tools.

.

.

All models are designed the same way and comparable in terms of performance and characteristics. On the other hand, their external dimension is suitable for the geographic market for which it is intended. Size 5 variant are consistent with the US dimensions: Customary Units. Their diameter is therefore of half-inch while the shaft is 0.125 inch. Motors are also equipped with “Servo Mount”, a type of fixing system widespread on this market. On the contrary, the EC 13 variant / GP 13 is intended for markets that use metric: outside diameter is 13 mm and the shaft is 3 mm. The motor is equipped with a flat flange with 3 threads on the front.

Application

  • Hand tools that can be sterilized, such as bone saw, bone drilling and grinding machine
  • Dermatological and dental tools
  • Infusion pumps

Shut-off screws Z94 and Z940 now available in a new size: M9x1 !

Hasco has added a small new product with a large savings potential to its portfolio. The proven conical shut-off screws Z94/… and the cylindrical version Z940/… have now been supplemented with the intermediate size M9x1.

.

The core hole diameter of M9x1 corresponds to the cooling channel diameter of 8 mm. This dispenses with the need for complicated and time-consuming mould changes and drilling work on the moulding machine. The thread can be cut immediately after production of the cooling channel diameter.

Through this addition to the Hasco product range, a time saving of up to 30% per shut-off screw, depending on the material, is guaranteed

Five years instead of six months…

“DryLin R” linear plain bearings from igus GmbH, Cologne, are lubricant-free, robust and corrosion resistant. The linear bearings with highly wear-resistant polymers are replacing metallic bushings in numerous cases. Maintenance intervals are shortened, service life increased.

A few examples
In a seat cover testing machine belonging to the American automotive components supplier, Lear Corporation in Allershausen, the “DryLin R” flange bearings have been in use without any failures for more than one and a half years. The load exerted on them is high in both Y and Z direction, and normally runs at a short stroke, (10 to max. 40 mm). In contrast, the linear guidance systems used before had to be replaced after only three months.

An even more drastic example can be found at a rubber factory in Gießen, Poppe Gummiwarenfabrik. Here, ball linings used in a cutting unit for rubber hoses failed after six months. The main reason was because of heavy talcum soiling. In the meantime, self-adjusting “DryLin R” linear plain bearings have been doing the job without any problems whatsoever for the past five years now.
Another prime example is The Austrian Montan University in Leoben, Steiermark. Here, the decision was taken to use linear plain bearings in a stone cutting machine used to saw enormous stone blocks after bearing guides had previously failed.

Picture: igus GmbH, Cologne. “DryLin R” linear plain bearings from igus GmbH, Cologne, are lubricant-free, robust and corrosion resistant. The dimensions correspond to those of linear ball linings.

“DryLin R”: Wear-resistant polymers especially for linear technology
“DryLin R” linear plain bearings from igus are based on highly wear-resistant polymers developed especially for linear technology. The standard gliding films are made of “iglidur J” material for excellent gliding friction coefficients, the high-temperature gliding films made of “iglidur X” ensure use with a long-term application temperature of up to 250°C. The dimensions of linear plain bearings are compatible with those of linear ball linings. DryLin bearings run on standard round shafts, and can be used with virtually any shaft material.

Built to last and corrosion-free due to special design
The special geometry makes “DryLin R” linear bearings robust even in heavy-duty environments, and ensures a very high level of safety even when running in coarse dirt. The design of the bearing surface with individual bridges and the interruptions in between is particularly advantageous here – as is the fact that no lubricant is required. Even if damp dirt does get onto the shaft, it is wiped off by the individual slide ways and pushed back into the contactless paths. The bridges of the bearing surfaces then slide over the path, which has been wiped free of all soiling.
The “DryLin R” range comprises gliding films and press-in bushings, linear plain bearings, housing bearings, flange housings as well as slides and linear housings. Suitable shafts and supported shafts as well as yokes and shaft brackets are also available ex stock.

Proportional Screw-in Cartridges with Slip-on Coil

The Swiss manufacturer Wandfluh AG develops and produces high-grade oil hydraulic control and closed-circuit control devices as well as digital amplifier – and control electronic circuits for world-wide utilisation. Wandfluh presents its new  proportional screw-in valves with slip-on coil.

The exchangeable coil significantly simplifies the logistics, because the solenoid coil can also be retrofitted. The various alternatives make the proportional screw-in cartridges a very flexible system. Different plug – voltage alternatives are available ex stock and are complemented with respect to individual adaptations – with the customary Wandfluh flexibility. In addition, the performance of the valves has been increased by the improved solenoid coil. Therefore also ambient temperatures of up to 70°C can be accepted without any performance loss. With the improvement of the corrosion protection of the solenoid coil, depending on the version, the valves achieve a salt-spray resistance of over 500h.

wandfluh
Available are valves with the standard cavities M22 and M33 in accordance with ISO 7789. Pressure relief valves are available as direct operated and pilot-operated versions up to volume flows of over 230 l/min and pressures of up to 350 bar. Apart from the optimised proportional throttle for volume flows of up to 63 l/min, the All-In-One valve QSPPM33 (tight seating volume flow controller) with mechanically preset Imin is in the Wandfluh product range. By the preset Imin the series spread of the valves is reduced to a minimum, in order to guarantee a simplification of the valve commissioning.
Typical applications for the qualitatively high-grade proportional screw-in cartridges are:

  • Sensitive adjustment of pressure, resp., volume flow
  • Speed control of hydro-motors
  • Cylinder control – and positioning
  • Individual adjustment of clamping – and tensioning force

Further information about the new compact proportional screw-in cartridges can be found under www.wandfluh.com.
