Enduro Loose Ball Bearings 3/32 (0.09375) BK-5043 Grade 25 Chromium Steel 100pcs

Enduro Loose Ball Bearings 3/32 (0.09375) BK-5043 Grade 25 Chromium Steel 100pcs

The Enduro BK-5043 set consists of high-quality loose steel bearing balls designed for servicing and rebuilding bicycle hubs, bottom brackets, and other bearing systems. While many modern bikes use sealed bearings, loose ball components are still widely found and remain essential for proper maintenance.

These 3/32 inch (0.09375) balls are made from Grade 25 chromium steel, offering excellent precision and consistency. Grade 25 balls meet or exceed a sphericity tolerance of 25 per 1,000,000, which is considered extremely round and ensures smooth rolling performance.

Not long ago, Grade 25 balls were regarded as a very high-end option, used only in the best hubs and bottom brackets. Today, Enduro uses even tighter tolerances in its sealed bearing ranges, but Grade 25 balls remain a durable and dependable choice for traditional loose-ball bearing applications.

Enduro offers loose bearing balls in a variety of materials, including chromium steel, ceramic, and silicon nitride, to suit different performance requirements. The BK-5043 pack includes 100 pieces, making it ideal for individual repairs as well as workshop use.
