Linear guides are a staple component in machine design where linear motion and load transfer is a requirement. The typical structure of a linear guide consists of a rail and a block with recirculating balls inside. The balls are retained with a ball retainer. This is very important because if balls fall out, this will cause an uneven loading condition in the block and can lead to catastrophic failures over time.
While we do not recommend taking the block off of the rail as it may introduce misalignment and unwanted particles into the system, it may be necessary to do so depending on your assembly and build requirements. In this video, our Engineers quickly illustrate how to properly remove a block from its rail without the balls falling out and reassemble the linear guide. Enjoy!
