Universal Ball Bearing - Features and Applications

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

1. 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.
2. Ultra-low Friction & Light Thrust: Rolling friction is much smaller than sliding friction, with a small starting force, labor saving and low noise.
3. Wide Load Range: Light-duty (several kg) → Heavy-duty (≥1 ton); the total load can be adjusted by the arrangement density.
4. Adaptability to Axis Deviation/Unevenness: Equipped with angular compensation, which can buffer installation errors and uneven ground/bottom surface.
5. 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
