Engineered for Tight Tolerances

These 8x12x3.5 stainless steel ball bearings are built for precision fit and repeatable performance in hobby RC models. Their sealed construction helps maintain consistent rotation under varied running conditions, making them a practical choice for both maintenance and modest upgrades.

Benefits of Stainless Sealed Bearings

Stainless steel resists corrosion and holds up well when exposed to moisture and grime. The seals keep abrasive particles out, reducing the chance of premature wear and helping the bearing roll smoothly for longer periods.

Practical Uses and Fitment Tips

Swap these bearings into wheel hubs, differentials or motor mounts that accept 8x12x3.5 sizes to cut friction and improve responsiveness. They are straightforward to replace and are commonly used where compact, reliable bearings are required.

Can I use these bearings in a wet or muddy environment?

Stainless steel helps resist corrosion, and the seals slow ingress of mud, but regular cleaning after wet runs is still recommended to preserve life.

Do these bearings need to be greased or oiled?

Sealed bearings are lubricated at manufacture and normally do not need additional grease; avoid forcing lubricant inside the seals which can cause seal damage.

What signs indicate a bearing needs replacement?

Listen for grinding or feel for rough rotation or side play. Any of these indicate the bearing should be swapped out to prevent damage to other parts.

Are these bearings compatible with metal or plastic hubs?

They can be used in both hub types as long as the seat diameter and width match the bearing. Check the hub tolerances before pressing bearings in.
