Refine Your Model with Serpent 1337 Bearings

Installing Serpent 1337 Precision Ball Bearings can tighten up drivetrain feel and reduce energy loss. These 15x21x4mm bearings are suited to various RC models and help maintain steady rotation under load.

What Sets Serpent 1337 Apart

Manufactured to consistent quality, the Serpent 1337 bearings offer dependable rolling with minimal play. They are useful for routine maintenance and for anyone seeking more consistent performance at the track or on club runs.

Are these bearings compatible with aluminium hubs?

Yes, they can be used with aluminium hubs as long as the 15x21x4mm bore and outer diameter match the hub spec. Ensure a snug press fit to avoid slop.

Should I relube after every run?

Not necessarily after every run, but inspect and relube when you notice dirt ingress or any roughness. Lighter oils suit high-speed on-road use; greases work for heavy duty applications.

How can I tell a bearing needs replacing?

Signs include rough rotation, excess play, noise, or visible corrosion. Replace bearings showing these symptoms to protect gears and shafts.

Can these help reduce drivetrain heat?

By lowering friction, precision bearings can reduce heat generated in bearings and adjacent components, helping drivetrain efficiency during long runs.
