Universal Ball Bearing is a bearing component capable of 360° omnidirectional free rolling. Its core features are multi-directional flexibility, low friction and strong adaptability, mainly used in scenarios such as planar conveying, precision positioning and flexible steering.
I. Core Structure and Features
Structure: Universal ball bearing is composed of a main ball, support balls/cage, base/outer shell; the main ball is exposed and can rotate omnidirectionally inside the shell.
Main Features
Omni-directional Movement (Multi-degree of Freedom): Objects can move smoothly in any direction (X/Y/rotation/oblique direction), solving the limitation that traditional rollers can only move in one direction.
Ultra-low Friction & Light Thrust: Rolling friction is much smaller than sliding friction, with a small starting force, labor saving and low noise.
Wide Load Range: Light-duty (several kg) → Heavy-duty (≥1 ton); the total load can be adjusted by the arrangement density.
Adaptability to Axis Deviation/Unevenness: Equipped with angular compensation, which can buffer installation errors and uneven ground/bottom surface.
Diversified Materials & Working Condition Adaptation
Carbon Steel/Bearing Steel: Universal, high load-bearing and wear-resistant
Stainless Steel (304/316): Rust-proof and corrosion-resistant (humid/chemical/food industries)
Ceramic: High temperature resistant, insulating and super wear-resistant
Nylon/Plastic: Lightweight, quiet and scratch-proof for workpieces
II. Typical Application Fields
1. Industrial Automation and Assembly Lines (Most Mainstream)
Assembly/Positioning Tables: Fine-tuning alignment and precision feeding of vehicle bodies, sheet metal and electronic components
Flexible Conveyor Lines: Workpiece steering, shunting, 90° direction change and station transition
AGV/Robots: Bottom support, precision docking and compensation for ground errors
2. Logistics Warehousing and Packaging
Sorting/Packaging Tables: Free sliding and manual steering of cartons/parcels
Shelves/Turnover Carts: Low-resistance pushing
Airport Luggage and Express Sorting: Universal ball tables realize arbitrary path shunting
3. Automobile Manufacturing
Welding/Assembly Lines: Three-axis fine-tuning and flexible assembly of vehicle bodies, battery packs and instrument panels
Painting Skids: High-temperature resistant universal support in drying ovens
Suspension/Steering Systems (Joint-type Universal Ball Bearings): Allow swing angle and transmit load
4. Precision Equipment and Medical Care
Testing/Inspection Tables: Micro-positioning and attitude adjustment of workpieces
CT/Medical Beds: Low noise, stable and precise displacement
Optical/Semiconductor Platforms: Dust-free, light-load and high-precision
5. Other General Scenarios
Furniture/Home Appliances: Universal wheels/pads at the bottom of sofas, refrigerators and cabinets
Molds/Heavy Workpieces: Translation and maintenance displacement
Food/Pharmaceutical Industry: Stainless steel and hygienic-grade conveying and steering
