BSSY Dual Nut Rotating Ball Screw Spline | High Precision Zero Clearance Rotating Spline Shaft for Automation Equipment

1. Product Brief Introduction

BSSY Dual Nut Rotating Ball Screw Spline is an integrated precision motion component integrating ball screw transmission and spline rotation functions. Adopting dual nut DB back-to-back bearing structure with 40° ball contact angle, it realizes zero clearance in rotation direction and ultra-high positioning accuracy. Equipped with large lead design and high-precision grinding raceway, the product features smooth high-speed operation, low noise and low friction. The integrated design of nut and bearing outer ring effectively reduces overall volume, simplifies installation and saves equipment layout space, widely applied in automated machinery, industrial robots and precision automation equipment.

2. Core Product Performance Advantages

Zero Rotational Clearance & Ultra High Positioning Accuracy: 40° ball contact angle paired with DB back-to-back bearing layout. Wide span between effective raceway centers greatly improves torque bearing capacity, eliminates rotation backlash and ensures outstanding positioning repeatability.
High Speed & Smooth Motion: All rotating ball screw splines adopt large lead design, supporting stable, rapid and smooth linear and rotary composite movement without jitter during high-speed operation.
Ultra Low Operating Noise: Precision grinding technology enables steel balls to move tangentially and evenly inside the nut, effectively reducing rolling resistance, friction and abnormal blocking noise during long-term continuous operation.
Compact Structure & Space Saving: Integrated forming of nut and bearing outer ring greatly shrinks the overall nut size, reserving more assembly space for the equipment frame, ideal for compact automated machinery layout.
Simple & Fast Installation: Only fix the outer ring of integrated nut-bearing to the support base during assembly, fewer matching parts, greatly shortening assembly cycle and lowering installation difficulty.
Strong Torque Load Capacity: DB back-to-back structure provides wide effective support span, outstanding rigidity and stable performance under frequent torque and composite load working conditions.

3. Main Application Scenarios

6. Frequently Asked Questions

Q1: What makes DB back-to-back dual nut structure superior?

A1: The DB layout widens the effective support span of rolling tracks, greatly enhances torque bearing rigidity, eliminates rotational clearance, and maintains high positioning accuracy under alternating torque loads.

Q2: Why can this spline run at high speed with low noise?

A2: Large lead design supports fast movement; ultra-precision grinding raceway ensures smooth tangential rolling of steel balls, minimizing friction, jamming and operating noise during continuous high-speed operation.

Q3: What are the advantages of integrated nut and bearing outer ring?

A3: It reduces overall component volume, saves equipment internal layout space, simplifies assembly procedures, only needs to fix the outer ring to the support seat to complete installation, effectively improving production assembly efficiency.

Q4: Can customized specifications be provided for special automation equipment?

A4: Full customization service is available. We can adjust shaft length, lead, preload, hardness and surface treatment according to customer drawings and actual working conditions to match various precision automation and automotive stamping equipment.
