Product Overview

Not all stainless steel is of the same quality. EasyBikeParts distinguishes itself by using 440C stainless steel for both the balls and races in its bearings. This alloy is renowned for its durability and exceptional resistance to corrosion, making it ideal for tough applications and harsh environments.

Why 440C Stainless Steel?

• High Durability: 440C stainless steel is recognized for its outstanding strength, hardness, and wear resistance.
• Superior Corrosion Resistance: Perfect for use in moist environments, areas with frequent washing, or where sweat exposure is common.
• Premium Material: As the priciest of the 440-series stainless alloys, 440C justifies its cost through advanced mechanical properties, developed via comprehensive heat treatments and cryogenic processes.

Performance

While stainless steel bearings typically have a 20% lower load capacity and are slightly softer than EasyBikeParts' standard steel bearings, they excel in environments where moisture is prevalent. These bearings are further enhanced with LLB type seals and Mobil grease for added protection against the elements.
