DIMECO roll feeder range results from a combination of 5 mechanical models and 3 numerical control packages. They fulfil your needs for strips from 0,1mm to 10 mm thickness and up to 2000mm wide.
Cutting edge roll performances are reached thanks to an optimized inertia to reach up to 1000 rpm and 150m/mn. Rolls are hardened, chromed and sand blasted for a better grip.
The use of a comprehensive electronic package (sensors, motors, controls) provided by the same supplier selected among worldwide leading O.E.M. provides outstanding positioning accuracy and reliability (+/- 0,05mm).
You can select the HMI that most fits your needs: simple but efficient with ECODRIVE, sophisticated with SIMOSTAR370, which offers access to the entire operating and maintenance data on a 12” colour touch screen.
With PFS and ADA functions, feeding line machines speeds and accelerations are synchronized according to press rate, feeding angle and pitch. Material strains are therefore avoided, loop length may be reduced and machine lifetime is increased.
Built-in electronic cams and active safety device controls are programmed directly from the feeder terminal. |

| 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)

| 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. |

| High performance roller chains and bush chains for drive and conveyor systems are available from stock. Every day new items are developed and applied for special applications successfully. We produce roller chains up to size 400 with 127 mm pitch, oilfield roller chains and marine-diesel roller chains. |
|
| All standard roller chains undergo continuous quality assurance and quality inspection. Iwis chains are pre-stretched, have a highly effective initial lubrication and are extremely wear-resistant with a service life significantly above the average. |

RKB double row taper roller bearings can take up heavy loads.
The basic styles are two row converging TDI configuration and two row diverging TDO configuration.
RKB bearings in TDI configuration have a double cone assembly and two single cups and they are generally supplied with a cup spacer.
The cup spacer is face ground after accurate measurement of the distance to obtain a predetermined internal play. Spacers or components may not be interchanged.
RKB also produces the taper roller steep contact angle TDIS version with higher thrust capacity than the TDI type.
These TDIS bearings have combination of face slots (e.g. N, N1, N2) and bore key-way for locking the cone on the shaft.
Also helical groove in the bore and lubrication grooves in side faces of double cone and/or retention sleeve with annular groove and lubrication holes can be provided.
RKB bearings in TDO configuration have a double cup, two single cone assemblies and can be supplied with a shaft supported cone spacer.
The TDO style bearings are mainly used in a floating cup mounting. Additional features of a lubrication groove and oil holes in the double cup for simplified lubrication through the outer ring are included (suffix CD).
In the TDO type the contact angle diverges, so the rigidity of the shaft mounting is increased.
Bearing sets with steep contact angle and intermediate ring, pierced rollers and steel pin-type cage (TDOS design), bearing sets with extended inner rings which abut each other (TDONA and TDONASW designs), bearing sets with heavy wall cup (TNASWH design) and bearing sets with shields of pressed steel (TDO 4422 design) are also in RKB manufacturing program. |

RKB four row taper roller bearings are installed as complete assemblies and take axial loads in addition to heavy radial loads.
For quick roll changes, they have a loose fit on the roll necks, but there is the disadvantage that the inner rings wander on their seatings causing wear. To reduce these negative effects they have a helical groov.
RKB produces these bearings in two base designs, TQO and TQI configuration.
The TQO type is composed in its standard configuration of two double cone assemblies, one central double cup, two single cups and factory adjusted cup and cone spacers.
Lubrication grooves and oil holes are provided.
The TQI type is composed in its standard configuration of one double cone assembly, two single cone assemblies and two double cups.
A four separated individual single cups configuration is also available.
It is also available the version with tapered bore (designation TQIT and TQITE).
In RKB sealed TQOS type sets, they have been developed to improve the lubrication in service.
The seals are produced in several designs depending on bearing size and application needs; the most common are the integrated lateral unitized seals (european version), the integrated lateral narrow seals (compact seal concept) and the loose flange lateral unitized seals (japanese version).
RKB seals have been redesigned in new type to increase seal durability and efficiency: these seals optimize the available space.
Phosphate treatment for rings, rollers and spacers (suffix PT4) is also available.
RKB produces special executions of TQO made of four single cups and two double cone assemblies (design without spacers). |

RKB multi row have low cross section, high load carrying capacity, stiffness and are used for metal rolling equipment in mills.
They are of separable design that considerably simplifies mounting, maintenance and inspection.
They can tolerate moderate to high shaft speeds. The rollers and outer races are carefully matched to ensure the best load distribution.
Inner rings (designation L) are interchangeable with other assemblies (designation R).
They have cylindrical bore and some sizes are also available with tapered bore.
The use of them in metal rolling mills exposes them to very heavy stresses.The rings and rollers can be manufactured with very high quality case hardened carburizing alloy steels. Deep case depth and special heat treatment ensure superior size stability, fracture toughness and reliability.
Where the bearings are mounted with a loose fit on the roll neck, RKB multi row cylindrical roller bearings have C2 internal radial clearance and are supplied with a helical groove in the bore and/or lubrication grooves in the side faces of the bearing rings for the efficient lubrication (e.g. suffix AC).
RKB produces the multi row cylindrical roller bearings in several construction.
The various designs differ basically in the number of inner and outer rings, in the number of loose or integral flanges on the outer ring, in the cage type, in the number of rollers in the cage pocket.
Furthermore, on order RKB can produce the bearings sealed at both sides by radial rubbing seals or with wider inner ring.
They are produced with the normal precision grade for roll neck bearings, conform to class P6 for dimensional and running accuracy to ISO 492. |
