Q1: What is the exact dimension of CR108710 floating seal?
A: The SKF CR108710 mechanical face seal has an inner diameter of 283mm. It is a standard HDDF / DF type metal face seal.
Q2: What is the difference between CR108710 and other floating seals?
A: The CR108710 is specifically engineered for relatively low-speed, high-contaminant environments such as mining and construction equipment. Its metal-to-metal sealing design with precision-lapped faces provides superior protection against mud, sand, and water, and it is designed as a direct OEM interchange for SKF 108710 and DF-type floating seal assemblies.
Q3: What equipment is CR108710 compatible with?
A: CR108710 floating seal is widely used in mining machinery (shearers, scraper conveyors, roadheaders, continuous miners), heavy construction equipment (excavators, bulldozers, loaders), and industrial gearboxes. It is commonly installed in final drives, track rollers, idlers, wheel hubs, and scraper conveyor sprocket assemblies.
Q4: What is the service life of this mechanical face seal?
A: Under normal heavy-duty operating conditions, the CR108710 floating seal provides 3,000–5,000 hours of reliable service life, significantly reducing maintenance frequency and replacement costs compared to standard seals. This is backed by an 18-month factory warranty.
Q5: How should I install the CR108710 mechanical face seal?
A: Installation requires ensuring the housing and seal faces are thoroughly cleaned before assembly. Specialized installation tools are recommended to avoid damaging the precision-lapped seal faces. The two metal rings should be installed face-to-face, and the O-rings should be properly seated without twisting. Refer to the equipment service manual for specific installation procedures. For detailed guidance, contact our technical support team.
Q6: Can I get a sample before placing a bulk order?
A: Yes, we welcome sample orders. We also provide material certification, dimension reports, and test certificates upon request to verify product quality before bulk order placement.
