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.

Product Description

Compact Precision: Small Slewing Bearings Engineered for Medical & Robotics Innovation

When your medical devices or robotics demand small Slewing Bearings that combine microscopic accuracy with whisper-quiet operation, LUOYANG INNO BEARING delivers. Our ultra-compact slewing rings (80–400mm diameter) are precision-machined to P4-grade tolerances, achieving noise levels under 35dB for MRI systems, surgical robots, and automated PTZ cameras. With 18+ years of expertise in miniature bearing design, we solve space-constrained motion challenges while meeting ISO 13485 and FDA compliance.

Why Precision-Critical Industries Trust Our Compact Slewing Solutions?

  • Medical-Grade Performance: ≤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.
  • Robotics-Optimized Agility: Smooth operation at 50–100 RPM for collaborative robot joints with 30% weight reduction.
