This is a one piece set of rubber sealed deep groove ball bearings from the 6000 series, covering models 6000 through 6008. The bearings are of the rubber sealed 2RS type, designed to protect lubricant and keep out dust and moisture. The set includes the 6005 bearing, which has a size of 25x47x12 mm. Key benefits Allinone set for convenient replacement across multiple applications using 6000series bearings (6000, 6001, 6002, 6003, 6004, 6005, 6006, 6007, 6008). Rubber sealed 2RS design helps retain lubrication and reduces the need for frequent maintenance in dusty or moistureprone environments. Standard deep groove ball bearing construction provides smooth rotation, low friction, and reliable radial support. 6005 in this set has exact dimensions of 25x47x12 mm, aiding quick compatibility checks for fitment. Suitable for both hobbyist projects and light industrial small machinery, offering a practical stock solution for common 6000series needs. Key attributes Type: Deep groove ball bearings, miniature Seal configuration: Rubber sealed 2RS Bearing range: 6000, 6001, 6002, 6003, 6004, 6005, 6006, 6007, 6008 Specific size noted: 6005 bearing 25x47x12 mm Compatibility: Designed to align with standard 6000series specifications for easy substitution in compatible shafts and housings Performance scope: Sealed design supports reliable operation with reduced exposure to contaminants Use cases Replacing worn bearings in small hobby motors, RC vehicles, drones, or robotics assemblies to restore smooth operation and responsiveness. Servicing 3D printers, small CNC machines, or precision equipment where compact, sealed bearings are used on linear axes or drive spindles. Refurbishing miniature gearboxes, lanterns, clocks, or other small mechanical assemblies that rely on standard 6000series bearings for radial support and smooth rotation.
