NBR Oil Seal 8x16x7 TC BASL - Double Lip Rotary Shaft Seal

Overview

The NBR Oil Seal 8x16x7 TC/BASL is a compact double-lip radial shaft seal with an 8 mm shaft diameter, 16 mm housing bore and 7 mm width.

The double-lip design combines a spring-loaded primary sealing lip with an additional protective lip. The primary lip provides dynamic sealing against the rotating shaft and helps retain lubricant, while the auxiliary lip helps protect the main sealing area against dust, dirt and other external contaminants.

Its small 8x16x7 mm dimensions make this seal particularly suitable for compact rotating mechanisms and assemblies with limited radial installation space.

TC / BASL Double-Lip Design

The TC / BASL configuration uses a primary sealing lip together with an additional protective lip.

The primary sealing lip operates directly against the rotating shaft and is supported by a garter spring to maintain sealing contact.

The auxiliary lip provides an additional barrier between the external environment and the primary sealing area, helping reduce the ingress of dust and contamination.

Compact 8x16x7 mm Dimensions

The principal installation dimensions are:

d: 8 mm
D: 16 mm
B: 7 mm

The small 8 mm shaft diameter and 16 mm housing bore make this oil seal suitable for appropriately designed compact mechanisms.

When selecting a replacement, all three dimensions should be checked together with the required lip configuration and material.

NBR Material

NBR (Nitrile Butadiene Rubber) is widely used in radial shaft sealing technology due to its good resistance to many mineral oils, lubricating greases and compatible technical fluids.

It is commonly selected for general machinery and mechanical sealing applications. Final suitability depends on the operating medium, temperature, shaft speed and actual working conditions.

Industrial Applications
