Lead Screw End Support

Manufactured in one piece using a CNC precision machining center, the coaxiality error between the main hole system and the installation datum is ≤0.003mm. Equipped with high-precision paired bearings, it effectively controls the radial runout and axial clearance of the lead screw, increasing the equipment's transmission accuracy by over 30% and meeting high-end needs such as precision positioning and micro-feeding.

The main body is made of 45# steel with quenching and tempering treatment (hardness reaching HRC28-32). Key stress-bearing parts adopt a fillet reinforcement design, enabling them to withstand large radial and axial forces without deformation or cracking under heavy-load conditions. Compared with ordinary cast iron support blocks, its load-bearing capacity is increased by 50%, and its service life is extended by more than twice.

• Quick-install positioning structure: Precision positioning pin holes are reserved on the base, eliminating the need for repeated calibration during installation and enabling quick alignment;
• Upgraded sealing protection: Adopts a double-lip dust-proof sealing ring to effectively block dust and oil from entering the bearing, adapting to harsh industrial environments;
• Optimized maintainability: The bearing end cover features a detachable design, facilitating later bearing replacement and lubrication maintenance, and reducing maintenance costs.

A variety of combinations of support types, materials, and precision grades are available. Customized production can be carried out according to requirements such as lead screw type (ball screw, ball spline), equipment working conditions (high-speed, heavy-load, low-noise), and installation space (compact/spacious). It can be perfectly adapted to both small precision instruments and large CNC machine tools.
