Method of manufacturing bearing device component coated with photoluminescence material, bearing device component and processing device with an indicator displaying information for a signal including information in accordance with light emission of a photoluminescence material applied on bearing device

A method of manufacturing a bearing device component, the bearing device including a shaft and a sleeve that surrounds the shaft, at least either one of the shaft and the sleeve being referred to as a work, and the method comprising:

• a process of forming a coating of an anti-sticking-lube polymer on the work;
• a process of applying a photoluminescence material to a range overlapping a range where the coating of the anti-sticking-lube polymer is formed;
• and
• a condition detecting process, the condition detecting process including:
• causing the photoluminescence material to emit light by causing the work to be irradiated with excitation light that excites the photoluminescence material;
• generating a signal in accordance with light emission of the photoluminescence material;
• inputting the signal into a processing device that determines information included in the signal;
• and
• detecting an applied condition of the photoluminescence material based on a determination result by the processing signal.
