Miniature Deep Groove Ball Bearings | High Precision for Medical, Optics & Robotic Arms
What Is a Miniature Deep Groove Ball Bearing?
Miniature deep groove ball bearings are compact, single-row radial ball bearings with small outer diameters, usually below 30mm. They follow the classic deep groove structure, capable of carrying radial loads and moderate axial loads at the same time.
Thanks to low friction torque, stable running accuracy and compact size, miniature deep groove ball bearings are the most widely used micro bearing type for precision equipment. They are available in both standard sizes and custom bearings versions to meet special tolerance, clearance and material requirements from industrial buyers.
Core Advantages of Our Miniature Deep Groove Ball Bearings
High concentricity & low noise: Strict P6 / P4 precision grade options, ideal for high-speed continuous rotation Light weight & compact outline: Fit limited installation space inside tiny assemblies Flexible customization: Internal clearance, shield/seal type, stainless steel material, special lubrication are all supported Stable performance: Long service life even under high-speed, low-load working conditions Fast sample support for project verification
Main Application ScenariosBearings for Optical Instruments
Optical instrument bearings require outstanding rotational smoothness and minimal runout. Our miniature deep groove ball bearings are commonly used inside optical lenses, focusing modules, microscope components and photoelectric detection equipment. Tiny vibration will directly distort imaging results, so we control the bearing runout tightly for optical system assembly.
Miniature Medical Bearings
Miniature medical bearing and medical miniature ball bearings are critical components for handheld medical turbines, diagnostic instruments and portable surgical devices. Stainless steel miniature deep groove ball bearings are preferred in medical industries for corrosion resistance and clean-running performance, suitable for repeated sterilization environments.
Precision Bearings for Robotic Arms & Automation
Precision bearings for robotic arms are essential for articulated robotic joints and small collaborative robot axes. Light preload and consistent rotation help robotic arms complete accurate positioning.As an automation bearings supplier, we supply matched miniature deep groove ball bearings for small automation actuators, linear modules and articulated arm assemblies. We also cover topics for bearing selection for articulated arms and different robotic arm bearing types for your engineering reference.
Size & Structure Introduction
Our miniature deep groove ball bearings cover 60, 62, 63, 67, 68, 69 series, which are mainstream micro deep groove series.Options: open type, rubber sealed 2RS, metal shielded ZZ.Material: Chrome steel / Stainless steel (AISI440C for corrosion-resistant applications).
How to Select the Right Miniature Deep Groove Ball Bearing
Confirm radial & axial load and continuous rotating speed
Define precision grade (general P0, high precision P6 / P4 for medical & optical)
Choose seal/shield type based on dust, liquid and lubrication environment
Check space limitation for bore, OD and width
Consult us for custom bearings if standard stock cannot match your drawing requirements
