/ Single row roller slewing bearings

small slewing bearing

1.Product Introduction: Lightweight slewing bearings with a diameter less than 400mm, suitable for small equipment, small in size and easy to install, with moderate load-bearing capacity, suitable for clean and compact space scenarios.
2.Structure Type: It has a thin-wall annular shape. The inner and outer rings are made of medium carbon steel, with built-in single-row small-diameter steel balls, engineering plastic cages, and small-diameter mounting holes evenly distributed. Some are without seals (suitable for clean environments).
3.Size Range: Outer ring diameter: 80 - 400mm, inner ring diameter: 60 - 360mm, height: 8 - 35mm.
4.Material: Inner ring / outer ring: 50Mn, 42CrMo; rolling elements: GCr15 bearing steel, GCr15SiMn (optional for impact resistance); seals: nitrile rubber, fluororubber (optional for oil and high temperature resistance).
5.Application Fields: Medical devices (turntables of operating tables), intelligent PTZ (monitoring cameras), small amusement equipment (mini turntables), household intelligent machinery.
6.Key Inspection Items: Deformation amount of thin walls, slewing flexibility.

Why Precision-Critical Industries Trust Our Compact Slewing Solutions?

1. Medical-Grade Performance in Miniature Packages

Silent Rotation: ≤35dB operation ensures patient comfort during MRI scans or robotic surgeries.
Biocompatible Materials: Stainless steel 440C/fluororubber seals resist sterilization chemicals.
Zero Backlash: Micron-level radial clearance (<0.005mm) maintains surgical tool accuracy.

2. Robotics-Optimized Agility

High-Speed Stability: Smooth operation at 50–100 RPM for collaborative robot joints.
Ultra-Light Design: 30% weight reduction vs. standard bearings through thin-wall engineering.
Custom Mounting Kits: Pre-drilled holes match KUKA/ABB/FANUC robot interfaces.

Solving Critical Challenges in Medical & Robotic Systems

A. MRI Machine Rotational Consistency

Our small slewing bearings eliminate image distortion by maintaining <0.01mm axial runout under 0.5T magnetic fields. Fluoropolymer-coated cages prevent RF interference.

B. Surgical Robot Lifetime Durability

Hybrid ceramic balls (Si3N4) and 58–62 HRC raceways extend service life to 200,000 cycles – 2× industry average for arthroscopic tools.

C. Legacy Equipment Modernization

Reverse-engineered replacements for discontinued bearings in Da Vinci Surgical Systems and GE MRI units, with 95% dimensional accuracy.

6 Reasons to Partner with INNO BEARING

1. Certified Compliance: Full documentation for FDA/CE submissions.

2. 15-Day Custom Lead Time: Modify bore sizes, seals, or gear teeth rapidly.

3. No MOQ Constraints: Order 1 prototype or 500+ production units.

4. Sterilization-Ready: Pass autoclave (135°C) and ethylene oxide tests.

5. 24/7 Technical Support: On-call engineers for emergency replacements.

6. Global Stock Hubs: 48-hour delivery to EU/NA robotics OEMs.

FAQs

Q: How do you achieve <35dB noise in medical-grade products?

A: Precision grinding (Ra 0.2μm finish) and nylon cages dampen vibration – tested per ISO 8579-2 standards.

Q: Can you match legacy bearing specs in obsolete surgical robots?

A: Yes! Share samples or blueprints for reverse engineering with 95%+ dimensional accuracy.

Q: What certifications support biocompatibility?

A: ISO 10993-5 tested materials with full traceability from melt to final assembly.

Q: Lead time for φ200mm custom bearings with gear teeth?

A: 12–15 days – 70% faster than competitors through modular production.
