Welding Positioners Slewing Bearing

Product Details

When your welding automation system demands consistent precision and reliable rotation, our Welding Positioners Slewing Bearing delivers exactly that. Engineered specifically for industrial robots and welding positioners, this high-precision slewing bearing features dimensions of 1300×998×100mm. It provides exceptional rotational accuracy with axial clearance controlled between 0.02-0.1mm, outstanding rigidity, and superior positioning repeatability. These characteristics make it an ideal solution for modern intelligent manufacturing environments where precise angle control and frequent start-stop cycles are critical for production efficiency.

The bearing incorporates precision-engineered raceway geometry that guarantees smooth, reliable movement throughout its service life. You'll benefit from its compact design that maximizes load capacity while minimizing installation space. Our manufacturing capabilities extend from 50mm to 10,000mm in diameter, so whether you require standard sizes or custom dimensions, we can meet your specific application requirements.

Constructed from high-strength 50Mn or 42CrMo alloy steel, the bearing undergoes specialized tooth surface quenching treatment. This process significantly enhances wear resistance and extends service life, even under demanding continuous operation conditions. The result is a robust component that maintains its performance characteristics over thousands of operational cycles.

Features and Benefits

High Precision Rotation
Axial clearance controlled within 0.02-0.1mm enables repeatable positioning accuracy of ±0.01°. This precision ensures your welding torch maintains the correct position throughout complex joint configurations, reducing rework and improving weld quality.

Frequent Cycle Capability
Designed to handle high-frequency start-stop operations without performance degradation. Your positioner can move rapidly between weld positions, reducing cycle time and increasing throughput on your production line.

24-Hour Continuous Operation
Robust construction and advanced heat treatment allow for continuous duty cycles. You can run multi-shift operations without scheduled bearing rest periods, maximizing equipment utilization.

Low Maintenance Design
A sealed raceway configuration minimizes contamination ingress. The low-emission, low-debris design is suited for clean manufacturing environments while reducing maintenance intervals and associated downtime.

Excellent Load Distribution
Optimized contact angle and raceway geometry efficiently distribute combined loads—axial, radial, and moment—across the rolling elements. This extends bearing life even when handling heavy workpieces at extended reach distances.

Applications

Our Welding Positioners Slewing Bearing serves as a critical component in various automation systems:

· Welding Positioners: Provides smooth, precise rotation for positioning weldments at optimal angles, improving weld access and quality

· Industrial Robots: Supports base rotation and axis motion in multi-axis robotic welding cells and material handling systems

· Turntables and Indexers: Enables accurate angular positioning in automated assembly lines and inspection stations

· Automated Workstations: Facilitates part manipulation in CNC loading systems and flexible manufacturing cells

The bearing particularly excels in applications requiring precise angle control combined with heavy load support, making it suitable for automotive component welding, structural steel fabrication, and pressure vessel manufacturing.

Testing & Certification

Every bearing undergoes comprehensive quality verification before shipment. Our testing protocol includes dimensional inspection on coordinate measuring machines, vibration analysis to verify smooth operation, and hardness testing of heat-treated surfaces. We maintain ISO 9001:2015 certification and produce all bearings in compliance with ISO and DIN standards. RoHS compliance ensures environmental responsibility across global markets.

Installation Guide

1. Pre-Installation Inspection: Verify mounting surfaces are flat, clean, and free from burrs. Check bolt hole alignment and thread condition.

2. Bearing Placement: Position the bearing carefully onto the mounting surface, aligning bolt holes. Avoid impact or dropping.

3. Bolt Installation: Install mounting bolts finger-tight initially. Use the specified bolt grade (typically 8.8 or 10.9).

4. Torque Sequence: Tighten bolts in a star pattern to the specified torque value in three stages: 30%, 70%, then 100% of final torque.

5. Gear Mesh: If using external gear drive, adjust backlash to manufacturer specifications (typically 0.2-0.4mm).

6. Final Verification: Check rotation smoothness by hand. Verify axial and radial play meet specification before applying power.

Our engineering team provides detailed installation drawings and can offer remote or on-site support for critical installations.

Maintenance and Care

Lubrication: Apply appropriate grease (NLGI Grade 2 lithium-based) to the gear teeth and raceways every 500 operating hours or quarterly, whichever comes first. Use a lubricant compatible with your operating temperature range.

Inspection Plan: Check mounting bolt torque monthly for the first six months, then quarterly. Inspect seals for damage or wear. Monitor gear teeth for abnormal wear patterns that may indicate misalignment.

Cleaning: Keep external surfaces clean using dry compressed air or soft brushes. Avoid high-pressure water jets that may compromise the seals.

Operating Practices: Avoid shock loads and operate within the rated load capacities. Sudden stops or starts accelerate wear on rolling elements and raceways.

Proper maintenance significantly extends bearing service life, protecting your investment and reducing the total cost of ownership.
