印度采购需求：齿轮箱、减速器、螺旋齿轮箱、工业齿轮箱、齿轮电机、齿轮箱电机

I'm looking to acquire a specific type of gear box known as the R series. Could you provide more detailed information about the specifications, features, and available options? I'm particularly interested in understanding the range of power ratings and size configurations you have, as well as the materials used in the construction. Additionally, it would be helpful to know about the lead times for production and delivery, as well as pricing details for bulk orders. Are there any customization options available? Please include any relevant certifications or standards your products meet, as this information is crucial for our purchasing decisions. Looking forward to your prompt response.
