In terms of performance, single row deep groove ball bearings with seals take into account both practicality and adaptability. First, the protection level can reach IP65 (some high-spec models can reach IP67), and can operate stably in water-sprayed and dusty environments, such as washing machine water inlet valves, outdoor motors, etc.; second, although the friction coefficient is slightly higher than open bearings and dust cover bearings, it still remains at a low level (0.0 02-0.006), suitable for medium and high-speed operation requirements, and the limit speed can reach 80%-90% of the basic model; thirdly, it has strong compatibility, and the dimensions are exactly the same as standard single-row deep groove ball bearings. It can directly replace the same type of open or dust-proof bearings without adjusting the equipment installation structure.
According to the material and performance of the sealing ring, this type of bearing can be further subdivided: in ordinary scenarios, ni…
