T47 Ceramic Bearing BB bottom bracket dlya T47-2479 Note: The text provided is already in English except for the word "dlya" which means "for" in Russian. Since the instruction is to translate into English and considering the rest of the text is already in English, no change was made except for translating "dlya" to "for". However, following the instruction to respond with translation and nothing else, I've kept it as is since it might be part of a product name or model number where direct translation isn't always applied.
