Construction Features • Pre-assembled. • No shaft wear. • Pressed into position in seconds. • Seals in grease or other lubricant. • Keeps out sand, dirt, grit and metal chips. Product Description Mini-Maze Type L is a package type, labyrinth seal consisting of two precision rings, an aluminum outer ring and a steel inner ring, that are permanently mated. The close clearance path (or labyrinth) is ideal for use as a combination seal and excluder for heavy lubricants and air, oil, and water mists. The seal acts as a nonsparking excluder because of the narrow space between the mating surfaces. The Mini-Maze Type M is for applications where higher pressure must be sealed or where labyrinth leakage must be minimal. Type M contains a series of equallyspaced milled slots in the outer ring which extend to the bottom of the groove in the inner ring. During rotation, the pumping effect which results is sufficient to force any leakage through the first groove of the seal and back to the sump or reservoir. Ordinarily, an annular groove in the bore of the seal retainer is employed to collect the linkage pumped through the slots. LABYRINTH SEALS Installation Instructions 1. Maximum allowable shaft movement: a: seals to size L100 – 0.005" radial ± 0.012" axial. b: seals above L100 – 0.008" radial ± 0.012" axial. 2. To provide proper positioning and avoid side contact of the labyrinth seal, it is recommended that the inner ring be positioned against a rigid shoulder. 3. To properly mount the Mini-Maze seal, a machined installation bushing is needed. The tool should be long enough to seat the seal against the shaft or housing shoulder. Preferably, the end of the tool which touches the Mini-Maze seal should be hardened to RC50 and should be ground to at least a 16RMS finish. This is to assure durability of the tool and mar-free installation of the seal. The I.D. of the tool should clear the shaft O.D., and the O.D. of the tool should be slightly smaller than the O.D. of the seal. 4. The shaft and bore dimensions should be machined to recommended dimensions. 5. The I.D. and O.D. of the Mini-Maze, prior to installation, should be coated with a lubricant compatible to your unit. To install, use a steady upward force... no hammering with a hammer. Apply steady pressure until seal seats against housing or shaft shoulder. 6. During operation, the level of the sealed medium (depending on its viscosity) should not be allowed to exceed the height of the inner face of the seal. 149
