What Is an SLT Headset Bearing and Why Does It Matter?
An SLT headset bearing uses an encapsulated solid plastic polymer instead of grease and a cage. This polymer fills the internal space of the bearing, creating a tight seal that blocks water, dust, and grit from reaching the bearing raceways.
It distributes just enough oil through the polymer to keep the bearing well lubricated, without needing re-greasing. The result is a fully sealed, maintenance-free bearing that performs reliably in wet, muddy, or high-load environments — ideal for riders who want more time on the bike and less time in the workshop.
How Does Solid Lubrication Technology Improve Performance?
SLT solid lubrication technology works by locking sufficient oil into a stable, self-lubricating polymer. This removes the need for loose grease while ensuring all internal surfaces stay protected during movement.
The otherwise solid polymer evenly distributes lubrication across load paths, reducing wear and improving performance under pressure. You’ll get consistent performance across road bike headset bearings, MTB headset bearings, and rear suspension pivots in high-impact conditions.
You can explore our full range of headset bearings or browse our bearing tools and accessories to help complete your installation.
Is an SLT Headset Right for Your Setup?
SLT headset bearings are the right choice if you ride regularly in wet, gritty, or high-impact conditions. They're especially suited for riders who:
- Need a corrosion-resistant and maintenance-free bearing solution
- Want longer service life and fewer replacements
- Value the performance of SLT solid lubrication technology
You’ll find these bearings in use across road, gravel, cross-country, and trail bikes. They are compatible with a wide range of headset designs.
