Why You Want To Work With A Company That Exceeds ...

When it comes to industrial machinery, precision in every detail is essential in order for the work being done to remain safe and efficient. There are a variety of industrial machines used in various industries that require lead screws to translate turning motion into linear motion. Lead screws are typically a small part of the overall machine, but they play an integral role in the function of the machine. From the biomedical industry to engraving, prototyping, heavy product or part lifting, robotics, and even data storage, lead screws are responsible for creating smooth, precise, quiet, and maintenance-free operation.

Other industrial machinery parts, such as helical gears, worm gears, Acme screws, square thread screws, and buttress thread screws, all play a part in the function and efficiency of a machine. However, over the course of a machine&#;s life, these parts will wear down and can begin to cause operation and performance issues.

At REMPCO, we specialize in manufacturing industrial machinery replacement parts, including lead screws. Whether you need a part replaced or you can&#;t find a specific part for your machine, we can manufacture or reproduce an array of components to exact specifications. The REMPCO team fully understands the importance of having the highest quality spare parts for your manufacturing equipment: because precision in every part is crucial. We strive to provide customers like you with parts that don&#;t simply meet your needs, but exceed expectations and industry standards.

There are various issues that can occur when lead screws and other threaded parts do not meet industry standards, such as additional noise and vibration, bending of the screw, greater backlash, and reduced accuracy. When these issues are bad enough, they can begin to affect the quality of the work, which in some cases may be significant.

• Vibration: Vibration can be caused when certain components are imbalanced, misaligned, worn down, or loose. When vibration is a symptom of a problem rather than due to normal operation, it can speed up the wear of the machine, use excess power, and when bad enough, can cause safety issues.
• Noise: Lead screw and nut systems generally operate without much noise, but excess noise can occur due to the material used to manufacture the screw or nut, the alignment of the system, or the orientation of the system. Although noise from lead screw systems isn&#;t a significant issue for small scale operations, noise pollution in some industrial machinery applications can be dangerous.
• Bending: Under certain loading conditions, lead screws could bend and lead to quality issues. To combat this, lead screws need to be manufactured with the greatest strength. Intermediate supports can also be used during operation to prevent bending.
• Backlash: The small space between the lead screw and the nut, backlash can cause movement of the components and inaccuracy, which is especially problematic in certain industrial machinery applications where precision is crucial.
• Reduced Accuracy: When there are issues with the thread of the screw or a failure to meet industry standards, shortcomings with the lead and pitch, or problems with the backlash of the screw, these can all reduce accuracy, resulting in severe quality issues.

In many industrial machining applications, accuracy is a necessary part of the operation that ensures reliable, high-quality finished work. To reduce the issues that lead to inaccuracy, one of the most important factors is utilizing lead screws that meet and even exceed industry standards. REMPCO has been manufacturing and reproducing industrial machinery parts since . Over our 40 years, we have been committed to providing customers with components made to their exact specifications with minimal to zero defects and no margin of error.

 Key advantages of Lead Screws:

• Zero maintenance
• No lubrication required
• Lower particulate generation (clean option)
• Longer life with non-catastrophic failure
• Quieter operation (no re-circulating ball noise)
• High helix/Fast leads (greater than 100mm/rev)
• Fine threads (as small as 0.3mm/rev)
• Non-backdriving (self-locking) leads
• Multi-function nuts
• Easily customized nut designs
• Zero-backlash with extremely light pre-load/low drag
• Much lower cost/selling price &#; 25 to 90% less!

Using both patented and proprietary technology, we build on these advantages and offer additional benefits.

 Champion Advantages of Haydon Kerk Lead Screws:
&#; Precision thread rolling offers lead accuracy of .mm/mm at approximately one tenth the cost of ground screws and lengths up to 4m.
&#; Polymer composite nut materials that provide high strength (dynamic loads of 250kg.), long life (over 750 million cm. of travel) while being molded to custom shapes to provide additional functionality.
&#; Anti-backlash nut designs that automatically compensate for wear.

 Ball Screw Applications
If the application can tolerate the high cost, the design limitations, the noise and the reduced life, the best ground ball screws offer greater maximum speed, lead accuracy and load capability. Rolled ball screws are less expensive than ground ball screws but have compromises that reduce these advantages. The user gets a high load rating but is left with a higher maintenance component, shorter life and less design flexibility, that may still cost several times more than a precision rolled Lead Screw assembly.

 High Speed Automation Applications
Lead Screws are successful in high-speed automation applications including semiconductor handling, laser scanning, engraving, transportation door actuation and valve actuation. Our thread rolling process produces fast leads available up to l00mm/rev that are both accurate and efficient.

 Medical and Lab Applications
Quiet operation is key in many medical and lab environments which can be a challenge for ball screws. The metal to metal contact of recirculating balls in a ball screw nut can generate
significant audible noise especially at high or even moderate speeds. The sliding action of a polymer nut on a steel Lead Screw is a much better option where audible noise is not acceptable.

 Food and Beverage Applications
Food and beverage wash-down environments are no problem. The materials used and the lubricant-free operation of Lead Screws allow total immersion in water, or many other fluids.

 Long Travel Length Applications
Long travel lengths over 4m are both possible and practical with leads of more than 75mm/rev and diameters of 20 to 25mm. This would be impossible for a ball screw. Thread grinding cannot produce these high-helix leads and the cost of a 4m ground screw would be huge. Yet the best Lead Screws are produced in many leads with accuracy of 0.mm/mm and special accuracy to 0.000lmm/mm. Rolled multi-start threads also avoid thread drunkenness caused by pitch-to-pitch error of ground or cut multi-start threads.

 High Helix, Fast Lead Applications
High helix, fast leads are possible in smaller diameters as well. We produce screws of 3mm diameter with leads of l0mm/rev. Screws with 6mm diameter and 25mm/rev leads are very popular in all types of equipment, including printing and scanning, data storage, medical analysis, paper handling, and semiconductor handling applications.

 Miniature Footprint Applications
Miniature Lead Screws, with and without anti-backlash compensation provide precision motion in a package size unmatched by other technologies. The ability to produce a high accuracy screw and nut, 2 to 4mm in diameter, with custom features has succeeded in bringing the latest data storage drives and telecommunications equipment to market.

 Self-Locking Vertical Axes Applications
Due to the mechanics of rolling elements, ball screws have higher theoretical efficiencies than Lead Screws. In practice, the differences are often smaller because of the effects of lubricant viscosity and manufacturing tolerances. It is these same efficiencies that prevent ball screws from offering self-locking, non-backdriving leads. Varying the material in a Lead Screw assembly enables fine and moderate leads to be non-backdriving.

 Money, Time and Space Savings
Saving money, time and space are some of the benefits of multifunction, custom-molded lead nuts. Using a variety of materials, Lead Screws offer higher performance at lower costs. Additional examples of multifunction nuts are shown to the right. Imagine how many parts would be needed to perform the functions if only a standard nut configuration was available. Then try to imagine getting this type of customization in a ball nut. Complex assemblies are reduced to single components. Complete solutions are custom engineered and delivered at a lower cost, and usually in less time than standard offerings from competitive technologies. A great option for design flexibility.

 Simplified Assemblies
Simplification of assembly and alignment, the nut incorporates the carriage and linear guide block. Although this is a high value Lead Screw, the customer sees reduced component costs and dramatically reduces assembly time. These Lead Screws have nuts with added functions that reduce part count, reduce tolerance stack-up, outlive, outperform and reduce overall product cost compared to more expensive ball screws and less expensive competitors&#; Lead Screws. These are 4 and 6mm diameter with fast leads used in data storage systems where precision, speed and cost are critical.
