Rotary Shaft Seal 17x35x7 NBR AO/TC

Applications

The Rotary Shaft Seal 17x35x7 mm in NBR (AO/TC), featuring a double-lip design, is engineered for demanding industrial and automotive scenarios where precision technical sealing is vital. This oil seal serves as a dependable shaft sealing ring in gearboxes, motor drives, hydraulic pumps, transmissions, and machine spindles. With its sealed construction and compact dimensions, it fits perfectly into bearing housings, bearing units and assembly lines that require long-term operational reliability and maintenance simplicity.

Advantages

• Double-lip (AO/TC) configuration - this design delivers dual protection: the primary lip retains lubrication while the secondary lip blocks ingress of contaminants such as dust and moisture. This significantly enhances overall durability and performance.

• Material: NBR (nitrile rubber) - renowned for its oil and grease resistance, the NBR elastomer ensures that the oil seal withstands industrial fluids and mechanical wear, enabling consistent performance in dynamic sealing environments.

• Compact and standardized size (17x35x7 mm) - these dimensions simplify integration, making replacement or stock-keeping easier for procurement teams and maintenance departments.

• Reduced downtime & lower lifecycle cost - by providing robust sealing performance, the product minimizes service interruptions and supports cost-efficient machine operation across its lifespan.

FAQ

Q1: What is the difference between double-lip (AO/TC) and single-lip oil seals?
A1: A double-lip design provides two lines of defence: one lip keeps lubricant inside, the second keeps contaminants out. This makes the seal especially suited for harsh or dynamic environments.
Q2: Why select NBR material for this shaft seal?
A2: NBR is chosen for its excellent resistance to mineral oils, greases and many industrial fluids. It is a cost-effective elastomer for applications where resilience and reliability are required.
Q3: What size shaft seal fits my application?
A3: Measure the shaft diameter (17 mm), the housing bore (35 mm) and the width available for the seal (7 mm). Ensuring matching dimensions is critical for optimal sealing performance.
Q4: In what industrial contexts is this seal best used?
A4: Suitable for automotive gearboxes, motor drives, industrial pumps, machine spindles, bearing housings — anywhere where a high-quality oil seal is required for a rotating shaft.
Q5: Does a double-lip seal reduce maintenance needs?
A5: Yes. The sealed construction retains lubricant longer and prevents contamination, reducing the frequency of maintenance interventions and extending uptime.
