DSG2020 Nut Housing

DSG2020 Nut Housing

Product Profile
The DSG2020 Nut Housing is a precision-engineered mounting bracket designed specifically for high-velocity 20mm ball screws, such as the SFE2020 and SFY2020 series. Unlike standard 20mm housings-which typically feature a 36mm bore-the DSG2020 is custom-machined with a 39mm bore to accommodate the larger nut bodies required for high-lead, high-speed motion.
 

Guaranteed Parallel Alignment
In high-velocity linear motion, alignment is the critical factor for longevity. If a high-lead ball screw is not perfectly parallel to the guide rails, the system will experience violent vibration ("whip") and premature fatigue. The DSG20H is precision-milled to an exact center-height tolerance. When paired with standard support units (e.g., BK15/BF15), it guarantees your ball screw remains perfectly parallel to the machine bed, ensuring smooth, vibration-free travel even at maximum RPMs.
 

Lightweight & Robust Construction
Machined from a solid block of high-strength aluminum alloy and finished with a corrosion-resistant anodized coating, the DSG2020 is engineered to handle the aggressive acceleration profiles of rapid automation. Its lightweight design minimizes the moving mass of the carriage, significantly improving system responsiveness and enabling sharper direction changes.

Key Features & Engineering Advantages
Precision-Engineered 39mm Bore: Specifically machined to accommodate the larger nut bodies of SFE2020 and SFY2020 high-lead ball screws, ensuring a secure, vibration-free interface.
High-Rigidity Aluminum Alloy: Constructed from premium, high-tensile aluminum alloy. This material provides an optimal balance of structural strength and low mass, which is critical for high-speed, dynamic motion systems.
Durable Anodized Finish: Features a professional-grade black anodized surface, providing superior resistance to oxidation and wear in demanding industrial environments.
Optimized Geometry: Specifically shaped to manage the increased momentum and vibration profiles associated with high-lead (20mm pitch) ball screws, ensuring long-term operational stability.
Precision Center Height: Milled to exact tolerances to ensure perfect parallel alignment with your linear guide rails, preventing premature binding or wear.
Standardized Mounting Interface: Equipped with industry-standard hole patterns, facilitating rapid, accurate integration into linear actuators, CNC gantries, and automated carriages.
