0.5mm Lead Ball Screw Series
The 0.5-mm lead ball screw series leads the way in the miniaturization of precision positioning devices.
A series of 0.5-mm lead ball screws has been created to meet requirements for small-sized and fine-feed ball screws necessary for reduced-size precision positioning devices.
This allows further size reductions in machinery and control units.

The LPR Series is a rolled ballscrew offering a lower cost than ground ballscrews. Return tube or end cap recirculation systems are available and square nut designs are offered for ease of installation on these ball screws. Shafts are available in standard, off-the-shelf lengths or can be cut to length.
The HTF-SRC series ballscrew evolved from the best-selling HTF series ballscrew designed for heavy load applications such as injection molding machines and other factory automation applications within the machine tool industry. They feature high speed and low noise. This ball screw series works effectively with heavy load driving machines that require high speed and high acceleration.
NSK's HMC series ball screw is specially designed to provide the high performance and speed required for machine tool applications. This ballscrew offers high speed linear motion, low vibration and noise, high rigidity, high load capacity, and compact nut design.

With eLINE ball screws it is now very easy to realize many different transport applications with standard products where customized solutions were often required up to now. eLINE ball screws are available ex stock, preassembled with nuts in screw-in or flange versions.
Unilateral screw end machining for the fixed bearing permits easy combination with LGL bearing units, complete with matching slotted nuts. Special attention was paid to the load capacity of the bearings. For small screw diameters the bearing journal diameter was enlarged by friction welding, thus increasing the load capacity of the end bearing arrangement.
Less stringent tolerances enable very economical solutions. For example, the mounted nut is always with clearance.
Seals are integrated as standard.

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.

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.

FLI has a wide range of ball screws to be able to provide adequate system for the linear movement.
Today, FLI has a large stock of ball screws :
- Precision rolled class C7 (53 μ m / 300 mm) according to DIN 69051. All the C7 class are on stock.
- FLI can also provide live high precision ballscrews Class C5 (18 μ m / 300 mm) with a deadline for manufacturing 30 to 40 days, depending on the workload of the plant.
However, in order to optimize the delivery time, we do have some class C5 in stock.
All the ballscrews are provided in standard lenght, cut and machining..

MRH-BP2 Series
Features
■Manufactured upon order
These are manufactured upon order because the spring on the nut has to be adjusted at the time of shipment(they cannot be removed).
■Backlash free design
Backlash free construction made possible with double nuts and a spring in between.(Patent pending)
■Custom order
Can be manufactured to order in quantities of one of more.
■Water resistant and corrosion resistant
The shaft is manufactured from SUS304,which gives excellent corrosion resistance and enables use underwater of in humid locations.
■Wide range of lead pitches
Different lead pitches can be selected for each screw shaft outer diameter.
■Lubrication-free
MRH incorporates a lubricating agent so it can be used without oiling.
Also,a polyamide type resin with good sliding properties is employed in the standard MRH nut material.
■Smooth transmission
Uses the same gothic arc grooves as ball screws,ensuring smooth transmission.
