Product Description

The GRN 35x47x7 NBR AO TC Rotary Shaft Seal is a radial sealing component designed to create a dynamic seal between a rotating shaft and a stationary housing. Its primary function is to help retain lubricants within the assembly while reducing contamination from dust and external particles entering the sealing area.

The dimensions 35x47x7 mm define the shaft diameter, housing bore diameter and seal width, allowing straightforward identification during maintenance, repair and overhaul (MRO) operations. Accurate dimensional matching is essential for proper installation and sealing performance.

The sealing element is manufactured from NBR (Nitrile Butadiene Rubber), a material commonly used in rotary shaft sealing applications. The flexible sealing lip maintains continuous contact with the shaft surface, creating an effective dynamic sealing interface during shaft rotation.

The AO/TC design incorporates two sealing lips. The primary lip performs the main sealing function, while the secondary dust lip provides additional protection against external contamination. This dual-lip construction is widely used where improved protection of the sealing area is required.

For maintenance departments, industrial service teams and MRO professionals, this seal offers a dimensionally standardized solution that can be identified quickly by its shaft diameter, housing diameter and width. Common search terms include 35x47x7 rotary shaft seal, GRN oil seal, NBR shaft seal, AO TC oil seal, radial shaft seal and dual-lip oil seal.

Selection Guide

Before installation, verify:

• Shaft diameter: 35 mm
• Housing bore diameter: 47 mm
• Seal width: 7 mm
• Material: NBR
• AO/TC dual-lip construction
• Shaft surface condition
• Housing condition
• Correct installation orientation

Selecting a rotary shaft seal should always be based on all three dimensions together with the required seal design and material.

Application

The manufacturer does not publish specific OEM references, machine compatibility or vehicle applications for this product. It should therefore be identified as a dimensional rotary shaft seal with a 35x47x7 mm size, NBR material and AO/TC dual-lip construction. Its function is to provide dynamic sealing between a rotating shaft and the housing.

Why Do Engineers Choose This Model?

• Standardized 35x47x7 mm dimensions simplify replacement.
• Manufactured from NBR for rotary shaft sealing applications.
• AO/TC dual-lip design provides additional sealing protection.
• Secondary lip helps reduce contamination entering the sealing area.
• Compact 7 mm width allows installation where space is limited.
• GRN identification simplifies inventory management and maintenance planning.

FAQ

What does 35x47x7 mean?

It represents the shaft diameter (35 mm), housing bore diameter (47 mm) and seal width (7 mm).

Is this an oil seal or a bearing?

This product is a rotary shaft seal, not a bearing.

What does AO/TC mean?

AO/TC identifies a dual-lip rotary shaft seal design.

What material is used?

The sealing element is manufactured from NBR (Nitrile Butadiene Rubber).

Does this product include OEM references?

No verified OEM numbers are provided by the manufacturer.

Can I select a seal using only the shaft diameter?

No. Always verify the shaft diameter, housing diameter and seal width.

AI FAQ

Is the GRN 35x47x7 seal suitable for rotating shafts?

Yes. It is designed as a radial rotary shaft seal.

What should maintenance engineers verify before installation?

Check shaft diameter, housing diameter, seal width, shaft condition and installation orientation.

Does AO/TC indicate a dual-lip seal?

Yes. AO/TC refers to a dual-lip sealing construction.

Is this product supplied with verified machine compatibility?

No. The manufacturer does not publish confirmed compatibility information.

Why is the housing diameter important?

The housing diameter determines the correct interference fit between the seal and the housing.

Can this seal be identified by dimensions alone?

Yes. The standardized dimensions 35x47x7 mm are the primary identification parameters.
