According to the different bearing series and sizes, there are two different designs. The seal ring is made of stamping steel, usually with a cylindrical extension at the inner diameter of the sealing ring, forming a long sealing gap with the inner ring shoulder. Some seals do not extend.
Bearing with low friction seal ring: the suffix is RSL, 2RSL or RZ, 2RZ, according to different bearing series and size, it also has different structural design.A very narrow gap to form a cylindrical surface or the inner concave contour of the sealing ring and the inner ring shoulder, is actually not contact, therefore, a low friction bearing seal and bearing with Z can run the dustproof cover at the same speed, but its better sealing performance.
Bearing with contact seal ring, the suffix is RSH, 2RSH or RS1, 2RS1 Sealed Angular Contact Bearings Sealed Angular Contact Bearings,Lip Sealed Angular Contact Bearings,Durable Sealed Angular Contact Bearings,Ball Bearing For Machine Tool Spindles LUOYANG AUTO BEARING CO.,LTD , http://www.lyautobearing.com

Company Introduction:
Ningbo Sanheng Refrigeration Control Co., Ltd is locates in Xikou Industrial Park, Fenghua, Ningbo City, Zhejiang Province, formerly known as Zhejiang Fenghua Sanshi Solenoid Valve Fantory, after decades of development, has formed a set of automatic control components of refrigeration independent research and development, production, sales and import & export trade in the integrated company.
In the company's decades of development, we have a professional refrigeration technology team with wealth of practical experience, self-developed special-purpose welding lines and unique testing equipment, and command of advanced injection technologies, meanwhile we focuse on improving the quality and stability of product, keep on investing in the introduction of various high-techequipment, now have a complete set of production equipment, such as high-precision CNC lathes, automated assembly lines and so on, can strictly controlproduct consistency and stability. Our company in 2002 passed ISO9001: 2000 international quality system certification, a variety of products obtain CCC, CQC, CE certification, some products have passed RoHS testing.
Our products are widely used by domestic and international manufacturers for a long time. Our FDF series small refrigeration solenoid valve is well received by the customer's favor, SHF series new refrigeration solenoid valve is improved on the basis of the traditional refrigeration solenoid valve, overcomes the lack of traditional refrigeration valve design, so that ti can adapt to the working environment of the new refrigerant well, to work more stable.
We will continue adhering to the purpose quality forever, service forever, and constantly on the professional road, work hard to become first-class automation components of refrigeration manufacturer.
