6202ZZ Bearing Material & Heat Treatment: What Makes 52100 Bearing Steel Durable?

08/28/2026

Every 6202ZZ bearing you can buy looks identical on the outside — 15 × 35 × 11 mm, two steel shields, eight balls. What separates a bearing that runs for years from one that spalls out within months is nearly invisible: the material inside and the heat treatment that shaped it. 52100 bearing steel (called GCr15 outside the US) is the high-carbon chromium steel behind roughly 90% of industrial bearings, and the way it is hardened determines the 60–66 HRC hardness that rolling contact demands. This

Bearing Failure Causes: 6 Common Failure Modes, Symptoms & Prevention Guide

07/26/2026

Understanding the common bearing failure causes is essential for preventing unexpected downtime in industrial machinery. An unexpected failure can halt a production line, damage adjacent shafts and housings, and turn a routine repair into an emergency call-out. Maintenance engineers, plant managers, and equipment operators all benefit from knowing what actually

Bearing vs Bushing: A Complete Comparison Guide for Engineers

07/24/2026

When selecting components for rotating machinery, engineers often face a fundamental decision: bearing or bushing? Both reduce friction between moving parts and support loads, but their design principles, performance characteristics, and ideal applications differ significantly. Choosing incorrectly can lead to premature failure, higher maintenance costs, and reduced equipment efficiency. This
