Bottom bracket Enduro Bearings T47 Internal SRAM DUB 86 mm Stainless Steel

BKS-0249 – an internal threaded T47 bottom bracket with stainless steel angular contact bearings, for an 86 mm shell, T47 framesets and SRAM DUB cranksets.

• Thread: M47 x 1.
• For SRAM DUB 28.99 mm axles.
• Stainless steel bearings.

Stainless steel angular contact bearings are pressed into precision-machined aluminum T47 cups, which thread directly into the bottom bracket shell. All Enduro bottom brackets are manufactured at the Enduro Bearings facility in California, USA, to high production standards.

This bottom bracket uses angular contact bearings with 440C stainless steel balls and races. They are designed for long service life and increased corrosion resistance in demanding applications and environments. Stainless steel bearings have 20% less load capacity and are slightly softer than the 52100 chromium steel used in most Enduro bearings. Stainless steel is a suitable alternative for wet conditions, frequent bike washing or situations where sweat may be a concern. The bearings also use LLB-type seals and CRC Marine Grease for additional protection against water and the elements. Enduro Bearings provides a three-year anti-corrosion guarantee.

The bearings in this bottom bracket have a 15º angular contact design and require a light preload for correct adjustment. Some cranksets have a built-in preload system. If yours does not, or if it is made of plastic, the kit includes a machined aluminum preload adjuster and a full set of bottom bracket spacers for precise chainline adjustment.

Enduro makes solutions for a range of bottom bracket standards on the market, with options at different price and performance levels, from standard ABEC-3 bearings to XD15 Ceramic Hybrid bearings with a lifetime guarantee.
