❓ Frequently Asked Questions (FAQs)
✅ Q1: What is this 45mm Nitrile End Cap used for?
A1: It is used to seal a housing bore statically where a shaft does not protrude, protecting the bearings and internal components from contaminants like oil, dust, and moisture.
✅ Q2: Can this be used in rotating applications?
A2: No. This is a static sealing component. It should not be used in applications where the shaft rotates or passes through the housing.
✅ Q3: Why is Nitrile Rubber used for the coating?
A3: NBR (Nitrile Rubber) offers:
-
Excellent oil and grease resistance
-
Good abrasion resistance
-
Operating temperature range of approximately -40°C to +100°C
-
A tight seal against contaminants and environmental exposure
✅ Q4: How is the Nitrile Rubber End Cap installed?
A4:
-
Clean the bore surface of the housing
-
Align the end cover with the opening
-
Gently press-fit using a seal driver or soft mallet
-
Ensure the seal is flush and undamaged.
