T47 threaded bottom bracket (BB) cups are designed for T47 frames and accommodate cranks with a spindle diameter of 24.00mm. These cups feature outboard bearings and are typically utilized in BB shells ranging from 68mm to 100mm in width. Crafted from machined aluminum, the cups thread directly into a T47 BB shell, facilitating easy installation.

The bearings are readily serviceable or replaceable for maintenance convenience. Additionally, a sleeve is included to fit between the cups, providing added protection against dirt and grime accumulation. It also serves to prevent internal wires and hoses from rubbing against the crank spindle.

Similar to standard BSA threaded cups, T47 BB cups have a left-hand thread on the drive side cup and a right-hand thread on the non-drive side cup. When installing in steel or aluminum BB shells, it's recommended to use a high-quality grease, while an anti-seize compound compatible with titanium BB shells is advised for optimal performance and longevity.
