Our Advantage

Engineered for Peak Precision and Reliability
The Zhejiang Baili ball screw locking nut, a core component of motion systems, features a unique preload adjustment design that precisely compensates for wear and eliminates clearance. This ensures long-term backlash-free stable operation, maintaining the machining accuracy and repeatability of high-end CNC equipment and precision instruments.

Superior Durability Under Demanding Conditions
The locking nut, made of certified alloy steel and advanced heat treatment, combines toughness and wear resistance. Its special surface coating provides corrosion resistance, micro-wear resistance, and anti-greasing properties, making it suitable for environments with contaminants, humidity, or temperature fluctuations. This reduces maintenance frequency and total cost of ownership.

Optimized for Efficiency and Ease of Integration
We prioritize seamless integration. The nut's user-friendly design simplifies installation and adjustment, reducing downtime. Its compact size and dimensional consistency ensure compatibility with various ball screw models, enabling quick upgrades. Choosing Baili guarantees enhanced productivity and minimized operational risk.

Our factory
At Zhejiang Baili Guideway Co., Ltd., our development of the Ball Screw Lock Nut is rooted in a foundational principle: critical components define the limits of your machinery's performance. We are not merely a supplier, but an engineering specialist dedicated to solving the core challenges of precision motion control. For years, we have observed that the lock nut is often the unsung determinant of long-term system accuracy and stability. This insight drives our entire approach.
Our R&D team, equipped with advanced simulation and testing labs, focuses exclusively on perfecting these vital interface components. We treat every lock nut as a system integrity guardian, subjecting it to failure-mode analysis and life-cycle testing far exceeding typical industry standards. This depth of focus allows us to engineer solutions for high-demand sectors such as precision machine tools, robotics, and medical imaging systems, where a micron of deviation or a moment of instability is unacceptable.
Choosing Baili means partnering with a company whose identity is intertwined with the mastery of precision mechanics. We bring a relentless focus on the minutiae that others overlook, ensuring our Ball Screw Lock Nut becomes the definitive factor in your equipment's reliability, quiet operation, and extended service life.
FAQ
Q1: How does Zhejiang Baili's lock nut design ensure long-term zero backlash compared to standard lock nuts?
A1: Our solution incorporates a proprietary multi-point axial pre-load mechanism, not a single-point lock. This design applies uniform radial force, actively compensating for microscopic wear over time. Combined with a precision-ground thread form, it maintains consistent pre-load force for over 10,000 hours of continuous operation in most applications, effectively eliminating performance degradation due to backlash.
Q2: What is the recommended procedure for initial installation and pre-load adjustment of your lock nut?
A2: We provide a detailed, step-by-step digital installation guide with torque specifications. The key is our patented graduated adjustment collar, which allows for micron-level pre-load setting using a standard spanner, eliminating the need for complex gauges. Our technical support team can also conduct a complimentary virtual installation review for your first-time setup.
Q3: Can you provide lock nuts compatible with ball screws from other major manufacturers (e.g., THK, NSK, Hiwin)?
A3: Yes, interoperability is a core design principle. We manufacture a comprehensive range of lock nuts with precise dimensional compliance to match the flange dimensions, thread specifications, and ball circle diameters of all major international ball screw brands. Please provide the competitor's part number or detailed drawings for a perfect match guarantee.
Q4: For applications in corrosive or high-temperature environments (>150°C), what specific material or coating options do you offer?
A4: Beyond standard hardened steel, we offer specialized alloys and surface treatments. For extreme corrosion, we recommend a duplex stainless steel body with a electroless nickel-PTFE coating. For high-temperature environments, we provide nuts made from temperature-stabilized tool steel with a solid lubricant-infused coating. Our engineers will consult on the optimal material science for your operating conditions.
Q5: What is included in your technical support and what is the typical response time for application engineering questions?
A5: Every purchase grants direct access to our Application Engineering Desk. Support includes lifecycle analysis, failure mode consultation, and system integration advice. We guarantee an initial response within 4 business hours for any technical inquiry. For critical issues, a senior engineer will be assigned to your case, providing solutions backed by our in-house simulation and testing data.
