Sealed 1-1/8'' TH-870E ACB bearing: reliable performance for the headset
The FSA sealed bearing model TH-870E ACB is an advanced technical solution for those seeking reliability and durability in their headset system. Designed with dual sealing to protect internal elements from dirt and moisture, this component ensures smooth, precise rotation even under demanding use. The Cr-Mo balls deliver superior mechanical strength, while the 45x45° architecture enables optimal load distribution during pedaling and cornering.
Technical specifications and headset compatibility
The bearing stands out for its compact, standardized dimensions: ID 31mm inner diameter and OD 41.8mm outer diameter, with an 8mm height that makes it suitable for 1-1/8 inch steerer tubes. The symmetric 45° contact angles ensure a balance between axial and radial stiffness, a crucial aspect for steering stability. The MR121 specification indicates the single seal configuration, which reduces friction while maintaining effective protection against external elements.
Materials and durability in extreme conditions
The composition of the 26 Cr-Mo balls measuring 1.8 inches provides greater fatigue resistance than standard steel bearings, allowing repeated load cycles without premature wear. The integrated sealing treatment reduces the need for frequent maintenance, extending the interval between cleaning and lubrication cycles. This bearing is ideal for cyclists tackling varied terrain and requiring high-performance components with long-term reliability.
Technical features
- Inner diameter (ID): 31mm
- Outer diameter (OD): 41.8mm
