摘要： A spring part, in particular for a driving device, includes a spring body extending around a central axis. The spring body comprises several spring windings which run radially around a spring axis and are made of at least a base material. The base material is surrounded at least by a first protective layer, and the spring body is at least partially covered on the outside by a lubricant. A method for manufacturing a spring part includes the steps of providing a spring body with several spring windings made of a base material and coating the base material at least with a first protective layer. The method includes the step of applying a lubricant formed as a silicone-based lubricant to the outside of the coated spring body.
