As a purchasing manager or technical director in the USA, you demand reliable linear motion components for CNC machines, automation systems, and robotics. But sourcing lead screw end supports often leads to frustration.
- High Prices: Competitors charge 20-50% premiums due to middlemen and import tariffs, eroding your ROI.
- Low Quality: Cheap imports fail prematurely, causing 37% downtime increase per industry reports from AMT – The Association For Manufacturing Technology.
- High Shipping Costs: Slow ocean freight adds $500-2000 per order and weeks of delay from unreliable suppliers.
- Inconsistent Quality: Poor tolerances lead to vibration, misalignment, and 25% reduced lifespan in high-speed applications.
- Limited Customization: Off-the-shelf units don't fit OEM needs, forcing expensive modifications.
- Supply Chain Risks: Disruptions from non-factory sources mean stockouts during peak production.
These issues cost US manufacturers $1.2 billion annually in linear motion failures (Rockwell Automation study, 2025). Ready for a better option? Explore YIDI's solutions below.

Technical Specifications: In-Depth Guide
Lead screw end supports (also called end support units) are critical for maintaining alignment, reducing deflection, and handling axial/radial loads. They feature angular contact bearings for preload, pillow block housings, and locking mechanisms. Our units support trapezoidal, ACME, and ball lead screws.
Key Parameters (1/3 of focus): We offer fixed (A-type, e.g., FK/FF) for drive-end thrust, floating (B-type, e.g., BK/BF) for free-end thermal expansion, and adjustable models. Materials: High-strength aluminum alloy (6061-T6) or steel for heavy duty. Bearings: ABEC-5 P5 precision, grease-lubricated for 10,000+ hours L10 life.

Frequently Asked Questions on Lead Screw End Supports
What is a lead screw end support unit?
A bearing block that mounts at screw ends to support rotation, handle loads, and prevent misalignment. Fixed types take thrust; floating allow expansion.
Can you customize lead screw end supports for USA applications?
Yes, full OEM/ODM: sizes 4-100mm, materials, preload. Compliant with RoHS/REACH for easy USA import.
What are shipping times and costs to the USA?
DHL/FedEx: 7-14 days, $100-500 (volume-based). Free samples under 5kg.
What payment methods do you accept?
T/T (30% deposit), PayPal, L/C, credit card for small orders. USD pricing.

Do you offer warranties and after-sales?
1-year warranty, lifetime tech support. Returns within 30 days, money-back guarantee.
How do fixed vs. floating end supports differ?
Fixed (FK/FF): Angular bearings for thrust. Floating (BK/BF): Cylindrical for radial only, prevents binding.
Are your products compatible with US regulations?
Yes: CE, RoHS, FCC, full traceability docs for customs.
