For a customer in Denmark, the end blocks of the Linear Unit RHL are milled to minimize the accumulation of dust and dirt inside the linear unit.* ### **Linear Unit RHL - one of Rollco's own solutions** [The Linear Unit RHL](https://www.rollco.eu/products/linear-unit-rhl) is a toothed belt driven unit designed by Rollco. It was developed to meet the market´s demand for short delivery times, while offering a cost-effective and flexible solution. The Linear Unit RHL is today a well-proven product that has been part of Rollco's product portfolio for many years. Since all manufacturing takes place locally in Helsingborg, there are excellent opportunities to easily customize the linear unit if needed. This flexibility can be more challenging when production is outsourced or when purchasing from an intermediary. ### **Machining of end blocks reduces the risk of dust and dirt accumulation** In environments with a lot of dust and dirt, there is a risk that contaminants penetrate the linear units and affect both their performance and lifespan. This is exactly the challenge that one of Rollco's customers faced. To solve the problem, they decided to machine the underside of the linear unit's end blocks. This solution prevented dirt and dust from accumulating and building up inside the unit. The milling was performed locally by Rollco's machining department in Helsingborg. ![End block](https://6400841.fs1.hubspotusercontent-eu1.net/hub/6400841/hubfs/%C3%84ndgavel.jpg?width=1200&length=1200&name=%C3%84ndgavel.jpg) *At the bottom, a section of the end block has been milled out, opening up the linear unit to allow dust and dirt to pass through.* ![RHL customization](https://6400841.fs1.hubspotusercontent-eu1.net/hub/6400841/hubfs/RHL_specialbearbetning.jpg?width=1200&length=1200&name=RHL_specialbearbetning.jpg) *The linear unit seen from below, fully assembled with belt in place.* ### **Innovative solutions for longer service life** At Rollco, we see it as an important task to not only deliver standard solutions but also to help our customers optimize their products for specific environments and requirements. Many times, small adjustments can extend the service life of a product or improve its performance. Local manufacturing makes it possible to test and adjust special solutions during the production phase, ensuring that the final product functions optimally in the customer's application. | #### **Features of Linear Unit RHL** - Toothed belt drive - Compact - Suitable for XYZ applications - Stroke lengths of +10 metres - Compatible with common aluminium profile systems | | --- | [![Choose the right telescopic rail with the help of our guide!](https://hubspot-no-cache-eu1-prod.s3.amazonaws.com/cta/default/6400841/interactive-245854267609.png) ](https://blog.rollco.eu/hs/cta/wi/redirect?encryptedPayload=AVxigLLxUb1%2Bs2%2B%2FFhv3XO0QlUPbyikT52A3Fa5rhl4EDTv5vsq1eKeAKrKRrQR4kT8prvmfyES0JOVWmJVs32h08g9Y8Ccl84t10nJCVZAfCeITswsBc0xF51dlBHkWQzaX73zpAqKM%2BPaGuca%2Bg0Xlj9ZujReowG66Cw8CzZe7XzOfjOSYL5TTT6DcvvFRNhQZWSsTbhiL9XcMBCGkxZBqf9U%3D&webInteractiveContentId=245854267609&portalId=6400841) Recommend to a friend or colleague: [![Share on facebook](https://blog.rollco.eu/hs-fs/hubfs/raw_assets/public/Rollco_Mars2022/images/facebook-color.png?width=24&name=facebook-color.png) ](http://www.facebook.com/share.php?u=https://blog.rollco.eu/rollco-customizes-linear-units-for-harsh-environments&utm_medium=social&utm_source=facebook) [![Share on linkedin](https://blog.rollco.eu/hs-fs/hubfs/raw_assets/public/Rollco_Mars2022/images/linkedin-color.png?width=24&name=linkedin-color.png) ](http://www.linkedin.com/shareArticle?mini=true&url=https://blog.rollco.eu/rollco-customizes-linear-units-for-harsh-environments&utm_medium=social&utm_source=linkedin) [![Share on twitter](https://blog.rollco.eu/hs-fs/hubfs/raw_assets/public/Rollco_Mars2022/images/twitter-color.png?width=24&name=twitter-color.png) ](https://twitter.com/intent/tweet?original_referer=https://blog.rollco.eu/rollco-customizes-linear-units-for-harsh-environments&utm_medium=social&utm_source=twitter&url=https://blog.rollco.eu/rollco-customizes-linear-units-for-harsh-environments&utm_medium=social&utm_source=twitter&source=tweetbutton&text=) [![Share on email](https://blog.rollco.eu/hs-fs/hubfs/raw_assets/public/Rollco_Mars2022/images/email-color.png?width=24&name=email-color.png) ](mailto:?body=https://blog.rollco.eu/rollco-customizes-linear-units-for-harsh-environments) - [LATEST POSTS](https://blog.rollco.eu) - [Streamline warehouse flow with smart linear units](https://blog.rollco.eu/streamline-warehouse-flow-with-smart-linear-units) - [Space-saving solution in storage systems](https://blog.rollco.eu/space-saving-solution-in-storage-systems) - [Warehouse automation with vision camera and linear units](https://blog.rollco.eu/warehouse-automation-with-vision-camera-and-linear-units) - [Multi-axis systems of linear units](https://blog.rollco.eu/multi-axis-systems-of-linear-units) - [The planetary gear – a partner to your linear unit](https://blog.rollco.eu/the-planetary-gear-a-partner-to-your-linear-unit) ```json { "@context" : "https://schema.org", "@type" : "BlogPosting", "author" : { "@type" : "Person", "name" : "Rollco", "url" : "https://blog.rollco.eu/author/rollco" }, "dateModified" : "2025-07-24T13:15:34.995Z", "datePublished" : "2025-06-04T10:00:00.000Z", "headline" : "Rollco customizes linear units for harsh environments", "image" : [ "https://blog.rollco.eu/hubfs/RHL_80_toppbild.jpg" ], "mainEntityOfPage" : { "@id" : "https://blog.rollco.eu/rollco-customizes-linear-units-for-harsh-environments", "@type" : "WebPage" }, "publisher" : { "@type" : "Organization", "logo" : { "@type" : "ImageObject", "url" : "https://blog.rollco.eu/hubfs/rollco_logotype.png" }, "name" : "Rollco AB" } } ```
