Spiracon is a high efficiency planetary roller screw which converts rotary motion to linear movement. Spiracon provides high dynamic load carrying capability up to 1200kN with high duty, life and positional accuracy ratings.
|
|
In roller screws, the load is transmitted from the nut to the shaft through the barrelled surfaces of all the engaged rollers. The diameter of the contact surface is substantially increased as is the number of points of contact.
Benefits
High load ratings (SR-SV)
Very high rotational speed (SR)
High acceleration and deceleration rates (SR)
Long life at high cycling rates (SR)
High reliability (SR-SV)
Resistance to hostile surroundings (SR)
Ability to survive shock loads (SR)
Small displacements with very good repeatability (SV)
Rotating the nut when speed becomes critical (SR)
Frequently removing the nut from the screw shaft (SR-most SV)

|
Nook Planetary Roller Screws are used in the most demanding and precise linear motion applications. With a greater number of contact points a roller screw provides stiffness and higher load ratings compared to a ball screw.
|
|
The screws with satellite rollers Rollvis are elements of machines of precision which are used to transform rotation movements into linear displacements and reciprocally.
The elements of bearing are threaded rollers laid out between the screw and the nut. The great number of contact points makes it possible the screw with satellite rollers to support very strong loads
The programme of sale of Elitec includes/understands screws with satellite rollers without recirculation of the rollers (constructions RV and BRV) and with recirculation of the rollers (construction RVR), that in various classes of precision.
In partnership with various types of nuts, Elitec delivers screws to satellite rollers for all the cases of application where high number of revolutions and/or strong loads are necessary.

Mink round brushes - Highly efficient tools with countless applications
Mink round brushes can be applied to solve problems in a wide range of areas, and our engineers have the ideas to exploit this potential. When it comes to flexibility, no industrial tool can match these brushes. We offer a huge selection of models: roller brushes (with stub shafts), round brushes (with hollow centre spindle, no shaft), the Mink HP-System (two half segments, without shaft) and the Mink Zick-Zack-System (modules, with or without shaft). Finally, there are Mink web spreader brush rolls for modern processing of plastic film, textiles and many other kinds of web.
Advantages:
• Suitable for goods of all kinds
• Versatile and economical
• Maximum cleaning power combined with optimum surface care
• Form and stiffness according to individual requirements
• Less need for cleaning agents thanks to the mechanical action of the bristles – economic and ecological benefits

Mink roller brushes (BW) - Individually configured roller brushes with shafts
Mink roller brushes differ from other Mink round brushes by virtue of their integrated shafts. Owing to the wide-ranging demands made on these brushes, especially in terms of shaft dimensions, there is no advantage in maintaining a stock range. Nevertheless, with our extensive experience in this area we are able to configure special brushes for you very quickly. On account of its extraordinary versatility the Mink Zick-Zack-System can frequently serve as the basis for a reliable solution.
Your advantage:
• Individual configurations for special purposes

Deburring and Roller Brushes
Use Deburring and Roller Brushes for a professional and perfect finish of cut edges. Diameter, filling material, measurements of the brush and the required bore are determined by the appointed machine and the work piece. We exclude any imbalance by evenly arranged filling material and the testing of every brush.
|
|
Deburring Brushes
Specially developed wheel brushes for deburring. These are suitable for all common deburring machines. Although they are heavier than other brushes because of their dense filling, we exclude any inbalance by evenly arranged filling material and the testing of every brush. Filled with high-quality wire, these brushes have a longer service life. All brushes are with double keyway. Please indicate the required bore.
Deburring End Brushes
These brushes are perfect for deburring tubes, profiles or even plane surfaces. Deburring end brushes are used in a set of 8, 16 or 24 single end brushes integrated in one deburring device. The metal bush fits all standard collets.

The modular principle underlying our one-way system of trapezoidal toothed roller brushes provides for fast, low cost changes of brushes. They can be installed and similarly removed by a simple hand operation. The teeth lock securely (and in a non-twist manner); as a result, a gap-free bristle surface is assured. Precise true running is guaranteed at all times. The DT system consists of brush segments which are mounted to the brush core with two locking collars. Due to the special modular principle on which they are based, worn individual segments on a roller brush can be replaced

The secret of our success at Tsubaki is the use of sophisticated computerized production techniques and a dedication to detail. Tsubaki RS Roller Chain bushings are specially produced for perfect concentricity and cylindrical accuracy. Tsubaki carburizes the pin surfaces using an advanced heat treating process. The link plates and rollers are shot- peened, and the surface areas between pins and bushings and between bushings and rollers are pre-lubricated. We then pre-load our roller chains continuously and accurately on multi-sprockets after assembly. The result is a great improvement in performance. We can confidently say that in terms of wear-life, durability, and maintenance cost Tsubaki RS Roller Chain clearly outperforms the competition.

Teleflex Morse coated helical cables and our competitor’s flocked cables were exposed to 240
hours of salt spray testing per ASTM B117. The results showed some red rust at the ends of the
Teleflex Morse cables and very small traces where the gear tooth broke through the plastic coating
after cycle testing. The flocked cables showed severe red rust throughout its length

Steel rods and pipes are mainly heat-treated using roller hearth furnaces. The high temperature consistency and low energy consumption of these furnaces, normally gas-fired, ensure reproducible quality and short treatment times. The processes used for heat treating non-alloyed and alloyed carbon steel pipes at temperatures between 450°C and 1050°C include stress relieving, recrystallizing, normalizing, soft annealing and spheroidizing in indirectly fired continuous roller hearth furnaces. For the spheroidizing of pipes made from high-carbon ball bearing steel, vacuum vestibules to completely isolate the furnace atmosphere from the surrounding air are essential, at least at the furnace entry. Vacuum vestibules are also needed at the entry and exit of continuous roller hearth furnaces for the bright solution annealing of high-alloy austenitic pipes. In the heat treatment of copper alloy bars and pipes, zinc, which can be easily oxidized, is the critical element in the alloy. Rapid cooling is essential to ensure that the zinc is kept in solution. This can be achieved using optional high-convection cooling chambers with a hydrogen atmosphere.
