Chrome Steel

SAE 52100 Chrome Steel is the most common material used in deep groove ball bearings. This type of steel is useful in most applications, it's not recommended for use in fishing reels or any environment where it is exposed to water, it has low corrosion resistance.

Advantages are high hardness for long life, low cost for high performance, operates at temperatures up to 150c, lower noise and higher hardness compared to stainless steel.

When selecting this option, you are receiving an ABEC 3 rated chrome steel bearing that is pre-lubricated and ready to use.

PTFE Contact Rubber Seals

The PTFE Rubber is bonded to a metal washer, the inner lip of the seal makes contact with the inner ring of the bearing to provide an effective seal against smaller particles such as dirt and dust, whilst protecting the lubricant from contamination and from leaking.
