Contaminants, swarf, dust or cooling lubricants can significantly affect the service life and performance of a ballscrew. HIWIN therefore offers a range of wipers and wiper systems for ballscrews, which reliably protect the shaft’s tracks from contaminants and enhance operational reliability.
Thanks to the optimal coordination of the ballscrew and the wiper system, users benefit from a longer service life, reduced maintenance effort and consistently high positioning accuracy, even under demanding environmental conditions.All available scraper variants are listed in the HIWIN Configurator, where they can be configured and ordered directly alongside the desired ballscrew.
Furthermore, our experienced engineers are happy to assist, if required, in the selection of the optimal type for the specific application.

What is the function of wipers in ballscrews?
Wipers protect the tracks of ballscrew shafts and ballscrew nuts from dirt and contaminants. They remove particles from the screw surface before they can enter the recirculation system, where they could cause increased wear or malfunctions. As a result, wipers make an important contribution to high operational reliability, a long service life and the sustained precise operation of the ballscrew.
They provide reliable protection against:
- Chips
- Dust
- Dirt particles
- Cooling lubricants
- Foreign objects
- Other contaminants
Why are wipers important in ballscrews?
The requirements for protecting a ballscrew vary considerably depending on the operating environment. The right type of scraper reliably protects the tracks from contamination and helps to maintain precision, operational reliability and service life in the long term.
Advantages at a glance:
- Longer service life of the ballscrew
- Less wear
- Longer maintenance intervals
- Greater process reliability
- Reduced downtime
- Lower operating costs
Which scraper type is right for my application?
The choice of the appropriate wiper type depends on the ambient conditions as well as the requirements for protection, lubrication and temperature resistance.
- NBR wiper (N): A universal solution offering high sealing performance, low friction and very good chemical resistance.
- NBR finger wiper (K): Ideal for use in highly contaminated environments with coarse swarf and dirt particles.
- Felt wipers (F): Particularly suitable for applications with increased requirements for temperature resistance and lubrication.
- Felt wipers (F): Particularly suitable for applications with increased requirements for temperature resistance and lubrication.
For which applications are ballscrew wipers particularly important?
Ballscrew wipers are particularly recommended for applications in which contaminants such as dust, swarf or cooling lubricants can impair the function and service life of the ballscrew. They provide reliable protection for the tracks and help to maintain precision and operational reliability in the long term.
Typical areas of application include:
- Machine tools and machining centres
- Packaging machines
- Wood and plastics processing
- Automation and production systems
- Special-purpose machine construction
- Applications involving cooling lubricants
- Environments with high levels of dust or dirt
Frequently asked questions about scraper variants for ballscrews
What is a wiper on a ballscrew?
A wiper removes contaminants from the ballscrew shaft and prevents dirt particles from entering the ballscrew nut.
Why are wipers important?
Wipers protect the tracks from contaminants and help to reduce wear and extend the service life of the ballscrew.
For which applications are special wipers required?
Wiper designs are particularly useful for machine tools, machining centres, packaging systems or applications involving dust, swarf or cooling lubricants.
Can wiper systems be customised?
Yes. HIWIN offers various wiper variants as well as bespoke solutions for specific environmental conditions and requirements.
Do wiper systems affect the service life of a ballscrew?
Yes. An optimally designed wiper system protects against contamination and can significantly increase both the service life and operational reliability of the ballscrew.
Which wiper variant is suitable for high levels of contamination?
NBR finger wipers (K) and felt finger wipers (V) are particularly suitable for applications involving coarse dirt particles, swarf or heavy contamination. They offer enhanced protection for the spindle raceways and prevent contaminants from entering the ballscrew nut.
