End Cup Seal EC 160x12 - Shaft Sealing Ring

Applications in Industrial and Automotive Environments

The End Cup Seal EC 160x12 is a robust technical seal ring designed to cap off housing openings where a shaft does not extend through the wall, offering effective protection of bearings and internal components. This rotary shaft seal variant is used in gearboxes, transmissions, static drive units, electric motors and other heavy-duty industrial applications where standard lip seals cannot be mounted in the shaft bore. It is ideally suited for both industrial applications and automotive systems, offering a cost-effective solution for end cover sealing in assemblies, and supporting both shaft seal and housing cover configurations.

Key Advantages and Technical Features

• Constructed for high durability: the EC design features a metal steel case coated with NBR (nitrile butadiene rubber) which provides excellent resistance to oils, grease, coolants and moderate temperature cycling.

• Efficient sealing solution: functions as a static cap for assembly holes or accessory mountings, providing sealing for open housings and protecting enclosed bearings or internal components from contamination and lubricant loss.

• Space-saving and installation-friendly: its shallow width and simple press-fit installation mean the EC 160x12 can replace blank covers without increasing the width of the installation or requiring major changes to the housing design.

• Ideal for industrial procurement: keyword-rich terms such as “rotary shaft seal”, “oil seal”, “shaft sealing ring”, and “technical seal” apply directly; the product supports high durability, resistance to oils and grease, and is suitable for industrial or automotive sealing platforms.

• Versatile compatibility: useful in hydraulic, automotive and machine-tool seals systems, where protection from dust, ingress and lubricant leakage is crucial.

Technical Specifications

• Product type: End Cup Seal (EC format)

• Size: Outer diameter 160 mm x width 12 mm (OD x W) - the inner bore adapts to housing diameter rather than shaft penetration.

• Material: Nitrile Butadiene Rubber (NBR) bonded to a carbon steel case - offering strong resistance to oils and grease in dynamic industrial and automotive seals.

• Application: end cover of gearbox, transmission, auxiliary drive housing or motor end cap where shaft does not pass through; acts as a stationary seal ring protecting internal components and bearing units.

• Key benefits: high durability, minimal maintenance, compact installation, strong resistance to contamination, oil and lubricant exposure, and suitability for industrial applications requiring reliable sealing solutions.

FAQ - Frequently Asked Questions

Q1: What distinguishes an “End Cup Seal EC 160x12” from a standard rotary lip oil seal?
A: A standard oil seal typically seals a rotating shaft through a housing bore; the EC end cup seal instead caps a housing bore where no shaft protrudes, acting as a protective cover or static seal ring.

Q2: What materials are most effective for high oil and grease exposure?
A: NBR (nitrile butadiene rubber) offers excellent resistance to oils, greases and moderate temperatures, making it a common choice for industrial end cup seals. For higher temperatures or aggressive fluids, fluorocarbon (FKM) may be chosen.

Q3: How do I select the correct size for an end cup seal?
A: Measure the outer diameter (OD) of the housing bore where the seal will press-fit and the width available. For the EC format you select an OD x width (for example 160 x 12 mm) that matches the bore.

Q4: Can the EC 160x12 seal be used in automotive gearboxes and transmissions?
A: Yes - it is specifically suited for securing housings, gearboxes, and accessory covers in automotive and industrial drive systems where robust sealing of internal components is required.

Q5: Is fast delivery available for industrial procurement?
A: Yes - the EC 160x12 model is stocked for industrial buyers and supports 24h dispatch to ensure minimal downtime in maintenance and operations.
