Import Bitzer 4tfcy Shaft Seal Made In China — Buy in Bulk from Supplier in China

The Bitzer 4TFCY shaft seal is a mechanical seal designed for rotary equipment in refrigeration and industrial systems. It features a rotary ring made from SUS304, SUS316, carbon, silicon carbide, or tungsten carbide, paired with a stationary ring of carbon, silicon carbide, or tungsten carbide. The secondary seal uses NBR, EPDM, Viton, or PTFE elastomers, and the spring is constructed from stainless steel SUS304 or SUS316. The seal operates within a pressure range of 0 to 1.2 MPa, rotational speeds up to 300 rpm, and temperatures from -40°C to +180°C, matching standard Bitzer OEM requirements.

These seals are engineered for durability under harsh conditions, with material combinations selected based on chemical exposure, temperature stability, and wear resistance. Carbon and silicon carbide are typical for high-temperature refrigerant applications, while Viton is preferred for aggressive chemicals. The 18 to 100 mm dimensional range covers most Bitzer compressor models in the 4TFCY series. Production follows ISO quality management procedures, though no certification number is provided. Packaging is minimal: each unit is wrapped in copy paper and boxed, then packed into export cartons per buyer request.

Buyers in the refrigeration, chemical processing, and automotive industries source these seals as direct replacements for worn OEM components. They are commonly used in commercial refrigeration compressors, industrial pumps, and hydraulic systems. Trade terms are flexible: delivery typically takes 15 days by sea, air, or courier, depending on destination. MOQ is not stated and must be confirmed with the supplier. Buyers should verify dimensional compatibility with their existing compressor model before ordering.
