Why are ball bearings used in machines? They solve three core mechanical challenges, making them indispensable for nearly all equipment with moving parts—from daily bicycles and household washing machines to industrial turbines and precision medical devices (like MRI scanners). Patented in 1869 by engineer Jules Suriray, this small component has since reshaped the efficiency of mechanical operations worldwide.
A standard ball bearing relies on five key parts working in perfect sync: High-strength alloy steel balls (the "rolling core") cut friction; a low-friction cage (made of engineering plastic or brass) keeps balls evenly spaced to avoid collisions; inner and outer rings link static and moving components (e.g., a motor shaft and its housing); and a dust cover seals lubrication while blocking dust and debris. A tiny "internal clearance" is also designed to prevent jamming when parts expand from heat during operation.

Their three pivotal functions make them irreplaceable:
Friction reduction: They turn energy-wasting sliding friction (e.g., between a car’s crankshaft and piston) into low-resistance rolling friction, cutting wear, heat buildup, and energy loss—cars use them to lower CO₂ emissions, while bikes feel lighter to ride.
Component connection: Acting as a "mechanical joint," they link independent static and moving parts (like a bike’s fork and wheel) without direct contact, ensuring stable motion and reducing mutual abrasion.
Load bearing: Different designs fit varied needs—self-aligning bearings handle slight axis misalignment for textile machines, while heavy-duty variants carry up to 50% of their static load, ideal for excavators or crane hooks.
Common types match specific scenarios: Radial bearings handle forces perpendicular to the axis (e.g., water pump impellers); angular contact bearings bear both radial and axial forces (e.g., machine tool spindles); linear bearings enable one-way sliding (e.g., printer paper guides). These variants cut maintenance costs and ensure precision for sensitive gear.
GQZ bearings applied in home appliances (washing machine drums) and heavy industry (turbine shafts)
For reliable, long-lasting performance, GQZ bearings stand out. Crafted with high-quality materials and precision manufacturing, they excel in low friction, stable connection, and strong load-bearing—perfect for everything from small home appliances to large industrial machinery. Choose GQZ bearings to keep your equipment running smoothly and efficiently.
