The SW 6204-ZZ bearing is engineered for demanding industrial applications requiring high rotational speeds and reliable operation under radial and moderate axial loads. Featuring a standard 20 mm bore, 47 mm outer diameter, and 14 mm width, this precision component is manufactured from premium 52100 high-carbon chromium steel (GCr15), ensuring exceptional hardness and wear resistance. The 'ZZ' designation confirms the inclusion of two non-contacting pressed steel shields, permanently affixed to retain lubricant (Grease-filled for life) and protect the raceways from contaminants such like dust and debris, thereby significantly extending service life and minimizing friction.
SW bearings are the optimal choice for maintenance managers and engineers prioritizing uptime. The optimized internal geometry allows for quiet operation and reduced heat generation, making the 6204-ZZ ideal for electric motors, gear reducers, pumps, and ventilation equipment. Designed to meet stringent ISO standards, this bearing delivers superior load carrying capacity (C_dynamic: 12.7 kN) compared to standard commercial offerings. Choosing the SW 6204-ZZ ensures high durability and low total cost of ownership (TCO) through extended maintenance intervals, offering professional-grade reliability across critical manufacturing processes.
