Professional FAQ for Standard Hydraulic Dustproof Wiper 50×62×7/10 DKBZ Oil Seal

1. What material grades can be used for DKBZ wiper oil seals?

NBR (Nitrile) is standard for oil/hydraulic compatibility and economy. For high temperatures/chemicals, FKM (Viton®) or advanced PTFE blends are available, often steel-cored for deformation resistance.

2. What are the recommended installation tolerances and standards?

Follow ISO 6194-2: ID (H10), OD (h9), width ±0.2 mm. Groove dimensions must match seal cross-section; chamfers are advised for lip protection.

3. What is the difference between single-lip and double-lip DK-series designs?

Single-lip: Basic dust exclusion. Double-lip: Enhanced dust + moderate secondary sealing, suitable for high-cycle, exposed applications.

4. How to select width: 7 mm vs 10 mm?

7 mm for standard compact cylinders; 10 mm for heavy-duty, deep grooves or higher lateral shaft movement.

5. Are these seals FDA or food-grade certified?

On request, PTFE or FKM compounds can be verified for FDA 21 CFR 177 food contact compliance. Standard product is industrial grade.

6. Can I use the same wiper for both oil and water?

NBR works for both, but for aggressive water/chemicals, PTFE is preferred. Always verify compatibility with planned process media.

7. What is the typical shelf-life and storage condition for these oil seals?

Up to 5 years in sealed packaging, cool & dry (ISO 2230 storage guidelines.
