There are several reasons why it's essential to confirm the end pitch of the guide rail before installing it. First and foremost, the end pitch determines the clearance between the slider and the rail. If the end pitch is incorrect, it can result in excessive clearance, causing the slider to wobble or vibrate during operation. This can lead to reduced accuracy and premature wear of the guide and slider.
Another reason to confirm the end pitch is that it affects the preload of the linear guide. Preload is the tension applied to the guide rail to eliminate the clearance between the slider and the rail. The correct end pitch ensures the correct amount of preload, which ensures accurate and smooth motion.
Additionally, the end pitch affects the parallelism of the guide rails. If the end pitch is not uniform across the guide rails, it can result in misalignment and cause the slider to tilt or bind during operation, resulting in reduced accuracy and premature wear.
Confirming the end pitch of the guide rail is a crucial step in the installation process of linear guides. PINSI recommends checking the end pitch before installation and ensuring that it is within the manufacturer's recommended tolerance. If there is any doubt about the end pitch or any other aspect of the installation process, it's best to consult with a professional to ensure the optimal performance of the linear guide system.
In conclusion, the end pitch of the guide rail is a critical factor in ensuring the smooth and accurate motion of linear guides. Confirming the end pitch before installation is essential to avoid excessive clearance, incorrect preload, misalignment, and premature wear. PINSI offers high-quality linear guides and ball screws, and its commitment to precision and quality is reflected in its products.
