Steel 51200 Highest Quality Ball Bearings - Grade 10
Hardened ball bearings. These are high-quality ball bearings made from chromium AISI 52100 steel. Manufactured to grade 10 specification. The lower the grade the more round and smooth the bearing. Most standard bearings are Grade 1000. These bearings are hard-wearing and designed for use in applications where long life is needed.
Stainless Steel 404 Highest Quality Ball Bearings - Grade 10
Hardened ball bearings. These are high-quality ball bearings made from stainless steel 404. Manufactured to Grade 10 specification. These bearings are hard-wearing and designed to provide extra resistance to corrosion to that of 51200 steel. Great for use in applications where extra resistance to corrosion is required such as bottom brackets and headsets.
Ceramic Si3N4 Highest Quality Ball Bearings - Grade 5
The toughest and smoothest bicycle ball bearing available. Made to Grade 5 specification, these ceramic bearings provide the greatest reduction in drag resistance and provide excellent strength. Ideal for applications where minimal drag and high corrosion resistance are required.
The perfect replacement for many FSA headsets, Shimano cup and cone hubs, pedals and any application that uses loose bearings.
