FKM FPM Viton Oil Seal 30x62x7 SC - Single Lip Rotary Shaft Seal

FKM FPM Viton SC 30x62x7 mm - Single Lip Rotary Shaft Oil Seal

Product Description

The FKM FPM Viton SC 30x62x7 mm is a single-lip radial shaft oil seal designed for rotating shafts with a nominal diameter of 30 mm. Its dimensions are 30x62x7 mm, and the sealing element is manufactured from FKM/FPM fluoroelastomer. The SC designation identifies a conventional single-lip oil seal with a rubber-covered outer diameter and a spring-loaded primary sealing lip. The specific manufacturer has not been identified.

This seal is intended to retain lubricants and limit leakage between a rotating shaft and a stationary housing.

Technical Specifications

What Does SC 30x62x7 FKM/FPM Mean?

SC identifies a single-lip rotary shaft oil seal with a rubber-covered outer diameter and a spring-loaded primary sealing lip in commonly used SC/TC nomenclature.

30x62x7 mm specifies the nominal dimensions:

• 30 mm - shaft diameter.

• 62 mm - housing bore diameter.

• 7 mm - seal width.

FKM/FPM refers to fluoroelastomer rubber, a material family used for resistance to many industrial oils, fuels and elevated operating temperatures.

Viton is a registered trade name for certain fluoroelastomer compounds. The term does not independently confirm that the seal is manufactured from genuine Viton-branded material.

SC Single Lip Oil Seal Construction

The SC 30x62x7 FKM/FPM oil seal uses a conventional radial shaft sealing design consisting of a rubber-covered outer body, a reinforcing insert, a primary sealing lip and a circumferential garter spring.

The primary sealing lip contacts the rotating shaft to reduce lubricant leakage, while the outer elastomer surface provides static sealing within the housing bore.

Unlike a TC double-lip oil seal, a standard SC design does not have an additional auxiliary dust lip.

FKM/FPM Fluoroelastomer Properties

FKM/FPM is used in industrial seals where chemical compatibility and thermal resistance are important.

Typical material characteristics include:

• Resistance to many mineral and synthetic oils.

• Compatibility with numerous fuels and hydrocarbons.

• Improved resistance to thermal ageing compared with standard NBR.

• Resistance to ozone and weathering.

• Suitability for selected elevated-temperature industrial applications.

The actual temperature limits, chemical compatibility and service life depend on the elastomer formulation, lubricant, shaft speed and operating conditions.

SC vs TC Oil Seals

SC and TC seals with identical dimensions are not automatically interchangeable because their lip configurations differ.

Selection and Interchangeability

Before selecting the SC 30x62x7 FKM/FPM oil seal, verify the shaft diameter, housing bore, installation width, sealing lip configuration and elastomer compatibility.

The suitability of the seal also depends on operating temperature, shaft speed, pressure, lubricant and shaft surface condition.

An NBR oil seal with identical dimensions should not automatically replace an FKM seal. Material properties and operating limitations may differ substantially.

Typical Applications

SC FKM radial shaft oil seals are commonly used in appropriately specified rotating mechanical assemblies, including industrial gearboxes, mechanical drives and lubricated shaft housings.

These examples describe potential applications of the seal category rather than confirmed OEM applications for this particular product.

Installation Recommendations

Clean the shaft and housing bore before installation. Inspect the shaft contact surface for grooves, sharp edges or corrosion.

Install the seal evenly using a suitable fitting tool. In conventional lubricant-retention applications, the spring-loaded sealing lip normally faces the lubricant.

Lubricate the shaft contact area with a compatible medium according to the manufacturer's installation instructions.

Frequently Asked Questions

1. What are the dimensions of the SC 30x62x7 FKM oil seal?

The nominal shaft diameter is 30 mm, the housing bore diameter is 62 mm and the width is 7 mm.

2. What does SC mean in an oil seal designation?

SC commonly identifies a rubber-covered, spring-loaded, single-lip radial shaft oil seal without an additional dust lip.

3. Is SC the same as TC?

No. Standard SC seals have one primary sealing lip, while TC seals also include an auxiliary dust lip.

4. Are FKM and FPM identical?

Both identify the same general family of fluoroelastomer materials, although individual compounds may differ.

5. Is every FKM oil seal made from Viton?

No. Viton is a specific material trade name, whereas FKM is a general elastomer classification.

6. Can an SC 30x62x7 FKM seal replace an NBR version?

Only after confirming chemical compatibility, temperature requirements, operating conditions and construction.

7. Does an SC oil seal have a spring?

A standard SC oil seal normally includes a garter spring that maintains contact pressure at the primary sealing lip.

8. Can an SC seal replace a TC seal?

Not automatically. The absence of an auxiliary dust lip may reduce protection against external contamination.
