Ball Screw Fixed Side
Our ball screw fixed side provides rigid axial support and stable positioning for precision ball screw systems, with preloaded bearing configurations matched to load, speed, and application requirements. Precision shaft-end and mounting compatibility helps simplify installation and maintain reliable linear motion performance.
Technical Specifications
Custom Ball Screw Fixed Side Configurations
Ball screw fixed side units can be configured around your ball screw drawing, shaft-end dimensions, mounting requirements, and operating conditions.
Drawing / Sample
You can provide:
• Ball screw or shaft-end drawings
• Existing fixed side samples
• Dimensions and tolerances
• Existing model or part number
• Load and speed requirements
We can use these details to evaluate compatibility and recommend a suitable fixed-side configuration.
Bearing Configuration
Bearing configuration can be selected according to:
• Axial and radial load
• Maximum operating speed
• Required rigidity
• Preload requirements
• Fixed-supported or fixed-fixed arrangement
The bearing arrangement can be confirmed before sample production to match the intended motion system.
Shaft-End & Mounting
We can match the fixed side to:
• Fixed-end journal diameter
• Bearing seat and shoulder dimensions
• Locknut and thread requirements
• Center height
• Mounting-hole pattern
• Available installation space
Dimensional details can be reviewed against your ball screw and machine structure before production.
Sample Approval
We support pre-production samples for:
• Dimensional verification
• Shaft-end compatibility
• Mounting fit
• Bearing configuration confirmation
• Running performance evaluation
Approved samples can be used as the production reference for subsequent bulk orders.
Bulk Production
For repeat and volume orders, production can follow the approved specification for:
• Fixed-side dimensions
• Bearing configuration
• Preload
• Housing dimensions
• Surface treatment
• Inspection requirements
Production and inspection records can be maintained according to the confirmed project requirements to support batch-to-batch consistency.
OEM Service
We support custom:
• Fixed-side dimensions
• Bearing configuration
• Mounting interfaces
• Shaft-end matching
• Surface treatment
• Packaging and labeling
• Customer-specified part numbers
• OEM production based on customer drawings or samples

Quality Control for Ball Screw Fixed Side
Dimensional & Shaft-End Inspection
Critical shaft-end dimensions, bearing seats, shoulders, threads, center height, mounting holes, and housing dimensions are inspected against the approved drawing, specifications, and applicable tolerances.
Bearing & Preload Inspection
Bearing configuration, preload, axial play, and critical bearing interfaces are checked against the confirmed specifications to support the required axial rigidity and positioning stability.
Load & Speed Verification
Applicable load, speed, bearing configuration, and operating requirements are reviewed against the approved application specifications to ensure the fixed side is suitable for the intended motion conditions.
Mounting & Compatibility Inspection
Fixed-side mounting dimensions and shaft-end interfaces are verified against the matched ball screw and machine structure to reduce alignment, installation, and replacement compatibility risks.
Running Performance Inspection
Rotation, running smoothness, friction, noise, and other specified functional characteristics are inspected before shipment to confirm stable operation under the approved configuration.
Inspection Records & Quality Documentation
Dimensional inspection records, quality reports, and surface treatment inspection records can be provided according to project requirements, with production managed under ISO 9001 quality procedures.

FAQ
Q: Can a Ball Screw Fixed Side Be Used for Ball Screw Replacement Projects?
A: Yes, a replacement fixed side can be evaluated against the existing ball screw, shaft-end dimensions, mounting interface, and operating requirements before ordering.
Q: What Is the Difference Between BK, EK, and FK Ball Screw Fixed Sides?
A: BK, EK, and FK fixed-side supports mainly differ in housing configuration and mounting structure, so selection should follow the available machine space and installation arrangement.
Q: Does the Ball Screw Fixed Side Need a Matching Floating Side Support?
A: Yes, a fixed-side support is normally paired with a suitable floating-side support to provide the required axial constraint and accommodate shaft movement in the complete ball screw system.
Q: How Does Bearing Preload Affect Ball Screw Support Performance?
A: Higher bearing preload can increase axial rigidity and positioning stability but also affects friction, running torque, heat generation, and speed suitability.
Q: What Information Should I Provide When Requesting a Ball Screw Fixed Side Quote?
A: Provide the ball screw diameter and lead, shaft-end drawing, mounting dimensions, operating load and speed, support arrangement, quantity, and any replacement model or sample available.
Q: Can the Fixed Side Be Supplied as Part of a Complete Ball Screw Support System?
A: Yes, the fixed side can be evaluated together with the corresponding floating-side support to help maintain compatibility across the complete ball screw support arrangement.
Q: How Can I Verify a Fixed Side Before Installing It on My Machine?
A: Compare the approved dimensional drawing or sample with the ball screw shaft end, mounting interface, and machine structure before final installation.
Q: Can Different Ball Screw Fixed Side Models Be Used for the Same Screw Diameter?
A: Not necessarily, because models with the same nominal screw diameter can still differ in housing dimensions, mounting configuration, bearing arrangement, and shaft-end requirements.
