What Information Is Needed to Select a Replacement Rotary Shaft Seal
Begin with the shaft diameter, housing bore diameter and required seal width. Then confirm the profile, material and operating conditions. Two seals with matching overall dimensions should still be checked for the intended application.
Which dimensions and design details should I record
- Shaft diameter, housing bore diameter and seal width, with units clearly stated
- Original profile, available installation space and outside-diameter construction
- Whether an auxiliary or dust lip is present
- Sealing-lip material, manufacturer markings and the original specification where available
Keep measurements, markings and assumptions in separate fields. If a detail cannot be identified, say so. A photograph can help describe the shape, but ask the supplier which dimensions need measurement or confirmation.
Use the Oil seals page to identify the product family before discussing a specific replacement.
What operating information belongs in the inquiry
Record shaft speed, lubricant or process medium, operating temperature and pressure difference. Include contamination exposure, shaft orientation and any known runout, alignment or surface-wear issues. These conditions affect selection; a temperature limit or speed figure should be considered with the conditions attached to it.
Does a matching size prove interchangeability
No. Ask the supplier to compare the proposed profile and compound with the original requirement. Identify any differences in the auxiliary lip, case construction or installation arrangement. A catalogue listing helps locate a candidate; it is not approval to install that candidate in every machine with the same dimensions.
What if the old seal failed early
Add a brief factual failure record: when leakage was noticed, what changed in service and what damage is visible. Preserve the distinction between observations and suspected causes. For example, “leakage after the operating temperature changed” records a sequence without proving a material failure.
What should be confirmed before the order
Request the proposed seal specification and the operating conditions used to select it. Confirm that the equipment owner’s installation and inspection requirements will be followed. This guide organizes a replacement inquiry; it does not establish compatibility or predict service life.
