30x62x10 NBR A/SC GRN® Single Lip Radial Shaft Oil Seal

30x62x10 NBR A/SC GRN® is a single-lip radial shaft oil seal measuring 30x62x10 mm, manufactured from NBR - Nitrile Butadiene Rubber.

It is designed for a 30 mm shaft and 62 mm housing bore, with a total width of 10 mm.

The A/SC configuration uses a spring-loaded primary sealing lip without an additional dust lip.

A/SC Single-Lip Design

The A/SC design uses one primary sealing lip responsible for dynamic sealing against the rotating shaft surface.

The primary lip is supported by a garter spring, which helps maintain radial contact between the elastomer sealing edge and the shaft counterface.

This version does not have an additional dust lip.

The single-lip configuration is the key construction feature that distinguishes A/SC from the corresponding AO/TC double-lip design.

What Does 30x62x10 Mean?

The designation 30x62x10 mm defines the three principal installation dimensions:

30 mm - nominal shaft diameter
62 mm - nominal housing bore diameter
10 mm - seal width

Dimensions alone do not provide complete product identification.

For this version, the NBR material and A/SC single-lip configuration should also be verified.

Spring-Loaded Primary Sealing Lip

The primary sealing lip operates directly against the rotating shaft and provides the main dynamic sealing function.

A garter spring helps maintain consistent contact between the sealing edge and the shaft counterface.

The principal dynamic sealing interface consists of:

primary sealing lip + garter spring + shaft counterface

The condition and surface finish of the shaft counterface are therefore important for proper seal operation.

No Additional Dust Lip

30x62x10 NBR A/SC GRN® is a single-lip version.

It does not have the secondary dust lip found in the corresponding AO/TC double-lip design.

This is an important identification feature when comparing radial shaft seals with identical 30x62x10 mm dimensions.

NBR Nitrile Rubber

The 30x62x10 A/SC GRN® seal is manufactured from NBR - Nitrile Butadiene Rubber.

NBR is widely used for radial shaft oil seals operating with compatible mineral oils, lubricating greases and industrial lubricants.

Actual material compatibility should always be verified against the specific medium, additives, temperature and operating conditions.

30x62x10 A/SC vs 30x62x10 AO/TC

These two GRN® radial shaft oil seals have the same basic 30x62x10 mm dimensions, but their lip configurations are different.

30x62x10 NBR A/SC GRN®:
single spring-loaded sealing lip
no additional dust lip

30x62x10 NBR AO/TC GRN®:
spring-loaded primary sealing lip
additional dust lip

Therefore, A/SC and AO/TC should not be treated as identical seal designs, even when the dimensions and NBR material are the same.

How to Select 30x62x10 NBR A/SC GRN®

For correct identification, verify:

Shaft Diameter: 30 mm
Housing Bore Diameter: 62 mm
Width: 10 mm
Material: NBR
Design: A/SC
Configuration: Single lip
Brand: GRN®

The dimensions alone are not sufficient for complete identification.
