Quick Reference
For mining, cement, and heavy industrial equipment. Chile and Peru — the world's #1 and #2 copper producers — have stable demand for spherical roller bearings. Zero import duty under China-Chile and China-Peru FTAs. High unit value, professional buyers, stable repeat orders. Spherical roller bearings accommodate shaft misalignment and handle heavy combined loads.

Why These Bearings
Double-row spherical design self-aligns to shaft deflection — tolerates up to 1–2.5° misalignment
W33 groove and holes allow pressurized lubrication directly to rolling elements
E-cage (pressed steel) design: compact, accommodates more rollers, higher load capacity
GCr15SiMn steel option for extreme temperature environments (cement kilns, steel mills)
Brass cage option for high-speed applications with reduced friction and noise
ISO 9001 certified — material certificates and dimensional inspection reports available
