CeramicSpeed T47a Shimano Coated Bottom Bracket

CeramicSpeed T47a Shimano coated bottom bracket with smooth-running and particularly durable ceramic bearings

The asymmetrically designed CeramicSpeed T47a Shimano bottom bracket is used to install a crank with 24 mm axle diameter in a T47a frame with 77 mm bottom bracket width. It features ceramic bearings that are harder than average, supple and resilient, with metal-coated races for added durability. In the T47a standard, which is used by Factor and other manufacturers, the left bearing cup is inside the shell, while the right bearing cup is mounted outside.

Ceramic Bearings by CeramicSpeed
CeramicSpeed ceramic balls are rounder, harder, smoother, lighter and more resilient than steel balls and ceramic balls from other manufacturers. CeramicSpeed ceramic bearings therefore last 3 to 5 times longer than other bearings on the market. All CeramicSpeed bearings are handmade in Denmark under clean room conditions and subjected to a strict four-stage inspection process. Among other things, the size of the ceramic balls is checked down to the thousandth of a millimetre. Tests are then carried out in the laboratory or preferably by professionals in training and competition. CeramicSpeed products guarantee you the lowest possible friction, optimised power transfer and maximum durability and also help you save watts and reach the finish line faster. It's not about seconds, it's about minutes!

Coated
Coated products from CeramicSpeed offer the ultimate gains in terms of performance and durability. This is due to a unique coating that increases the hardness of the races so that, in combination with the smoothness of CeramicSpeed ball bearings, virtually no wear on the bearings can be detected. The coating is a metal layer that is 75% harder than hardened steel. It is applied very thinly (0.003 mm) and evenly over the entire surface of the race and is used both internally and externally for optimum results.
