Standard Diameter Bearing 6205 Single-Row Deep Groove Ball Bearing

The diameter bearing 6205 follows unified metric industry standards, with three core size indicators: inner diameter, outer diameter, and width, which determine its installation compatibility and load capacity. The standard diameter bearing 6205 inner diameter is 25mm, which is designed to fit tightly with standard 25mm rotating shafts, ensuring stable shaft rotation and precise coaxiality. diameter bearing 6205 outer diameter is standardized at 52mm, matching the reserved bearing chambers of most mechanical parts. Meanwhile, the standard width of the bearing is 15mm, balancing structural compactness and mechanical stability perfectly .Weighing approximately 122 grams, the 6205 bearing features a compact and lightweight structure without sacrificing structural rigidity . All dimensional parameters are precisely calibrated, eliminating the need for customized modification in most conventional application scenarios. This standardized diameter specification is the key reason why the 6205 bearing achieves universal interchangeability among different brands.

Classified as a single-row deep groove ball bearing, the diameter bearing 6205 model inherits the classic advantages of deep groove ball bearing structures. Its deep raceway design enables it to bear both radial loads and bidirectional axial loads, adapting to complex force conditions in mechanical operation . Compared with other types of bearings, the 6205 bearing boasts extremely low friction coefficient, which effectively reduces rotational resistance, mechanical noise and vibration during operation, allowing it to support high-speed rotation stably .

To adapt to diverse working environments, the diameter bearing 6205 has derived multiple optimized variants on the basis of standard diameter dimensions. The 6205-2RS model is equipped with double rubber seals, which can effectively block dust, moisture and liquid contaminants, suitable for humid and dusty working conditions. The 6205-2Z model adopts double iron shields for dust prevention, ideal for dry and clean industrial environments . In addition, high-temperature resistant and corrosion-resistant customized versions are available, while retaining the original 25mm×52mm×15mm diameter and size specifications to ensure installation consistency.

Another prominent advantage of the diameter bearing 6205is its low maintenance cost. The sealed variants can achieve long-term lubrication without frequent oil supplementation, and its standardized structure simplifies disassembly, replacement and daily maintenance procedures . The stable diameter tolerance ensures minimal wear and deformation during long-term high-speed operation, extending the overall service life of mechanical equipment.
