How do I select a sealing solution for my equipment?
Start with the leakage location, motion, fluid and operating cycle. Prepare the mating dimensions and failure evidence so the proposed seal profile, compound and installation requirements can be reviewed together.
Rotating shafts and gearboxes
Provide shaft diameter, housing bore, available width, rotational speed, lubricant, temperature cycle and pressure. Include shaft finish and wear observations. Request confirmation of the offered lip arrangement, compound, spring and case specification.
Review the detailed purchasing checklistTruck wheel hubs and cassette seals
Identify the axle or hub assembly, original seal markings, mounting dimensions and installation orientation. Describe dust, water exposure and lubrication. Confirm the proposed cassette construction and installation method against the actual hub.
Review the detailed purchasing checklistHydraulic rods and pistons
Provide the groove drawing, rod or bore diameter, fluid, pressure peaks, stroke, speed and temperature. Review the seal profile, extrusion clearance and backup-ring requirements as an assembly.
Review the detailed purchasing checklistRecurring leakage or premature wear
Record when leakage starts, hours in service, operating changes and installation history. Photograph the removed seal, mating surfaces and wear pattern. Ask for a review of the likely failure causes and agree a controlled sample trial with measurable acceptance criteria.
