The DBH 6612 is a radial shaft seal from a brand we supply, built to keep lubricant in and contaminants out of rotating equipment. It measures 136.50 mm at the shaft, 168.27 mm at the housing and 15.87 mm in height. The Lz configuration pairs a sealing lip with a dust lip, which helps in areas where dirt or dust is present. Send us the part number or your dimensions and we will help you confirm the right seal.

This seal carries the designation 6612 from DBH. When reading the code, the three figures that matter for fit are the shaft diameter of 136.50 mm, the housing bore of 168.27 mm and the overall width of 15.87 mm. The Lz version adds a secondary lip to protect the primary sealing edge from dust. The elastomer is selected for resistance to oils and greases, and a steel spring keeps steady pressure against the shaft.

You will find this size in gearboxes, centrifugal pumps, electric motors, drive shafts and process equipment. It suits medium and large machinery running continuously. Mining, cement, paper and water treatment operations also use it where moderate peripheral speeds and airborne particles are normal. The Lz lip gives extra protection in those conditions.

Before installation, clean the shaft and housing and remove any burrs or scratches. Apply the same oil or grease used in the equipment to the lip. Press the seal in squarely with a proper installation tube, never striking the lip. Check shaft speed, operating temperature and chemical compatibility with the fluid. If the shaft is worn, a repair size or a sleeve may be needed.

For a replacement or an equivalent, send part number 6612 or your shaft and housing dimensions by WhatsApp or email. We can search other brands or lip designs while keeping the critical dimensions. We also help you choose the lip configuration that fits your application. Customers across the United States and in several Latin American countries rely on us for sealing and power transmission parts.
