ToggleComprehensive Guide to 1.1×4 Oil Seal: Dimensions, Pricing, Market, and Applications
An 1.1×4 oil seal is a specific type of mechanical seal used to prevent the leakage of oils or other fluids from a rotating shaft or housing. These seals are essential components in various machinery and vehicles, ensuring proper lubrication and protecting critical internal parts from contaminants such as dust, dirt, and moisture. The 1.1×4 oil seal is defined by its size (1.1-inch inner diameter and 4-inch outer diameter), but there are many factors to consider when choosing, purchasing, and using these oil seals. This article will provide a detailed breakdown of the 1.1×4 oil seal, including its dimensions, pricing, market trends, and applications.
1. What is an 1.1×4 Oil Seal?
The 1.1×4 oil seal is a type of radial lip seal, typically made from elastomeric materials like Nitrile Butadiene Rubber (NBR) or Fluorocarbon (FKM), that is used to contain fluids while preventing the entry of dirt and moisture into a mechanical system. Oil seals are used to provide a secure and reliable barrier between a rotating shaft and the surrounding housing or casing.
- Inner Diameter (ID): 1.1 inches (approximately 28 mm)
- Outer Diameter (OD): 4 inches (approximately 102 mm)
- Width: The width of an oil seal can vary, but it is typically designed to ensure proper seating in the application. The specific width of an 1.1×4 oil seal is often around 0.25 to 0.5 inches (approximately 6-12 mm), depending on the application.
The oil seal typically features a flexible sealing lip that makes contact with the shaft, creating a tight seal that prevents leaks. This lip is usually spring-loaded to ensure a consistent seal pressure and prevent deformation due to heat or wear.
2. Dimensions and Specifications of 1.1×4 Oil Seal
The key dimensions and specifications of the 1.1×4 oil seal are designed to provide the right fit and functionality for specific applications:
- Inner Diameter (ID): 1.1 inches (28 mm)
- This is the diameter of the hole through which the shaft passes. It must be accurate to ensure a tight fit and prevent fluid leaks.
- Outer Diameter (OD): 4 inches (102 mm)
- The outer diameter of the oil seal ensures that it fits snugly in the housing or casing. The larger outer diameter allows the seal to sit securely in place.
- Width: Typically 0.25 to 0.5 inches (6-12 mm)
- The width of the seal ensures proper engagement with the housing and the rotating shaft, allowing for efficient sealing without causing excessive friction.
- Material:
- Most 1.1×4 oil seals are made from durable rubber compounds like Nitrile Butadiene Rubber (NBR), which offers good resistance to oil, heat, and water. For more demanding applications, Fluorocarbon (FKM) can be used, offering superior resistance to higher temperatures and chemical exposure.
- Spring-loaded Lip:
- Many oil seals, including the 1.1×4 oil seal, come with a spring-loaded lip that ensures continuous pressure against the shaft. This feature helps the seal maintain its integrity over time, especially in environments with fluctuating pressures or temperatures.
3. Pricing of 1.1×4 Oil Seal
The price of an 1.1×4 oil seal depends on several factors, including the manufacturer (OEM vs. aftermarket), material quality, and supplier. Prices can also vary depending on whether the seal is purchased individually or in bulk.
Price Range:
- OEM (Original Equipment Manufacturer) Oil Seal: The cost of a high-quality 1.1×4 oil seal from an OEM typically ranges from $10 to $30 USD per unit. OEM seals are manufactured to meet the original equipment specifications and offer a reliable and precise fit.
- Aftermarket Oil Seal: Aftermarket seals generally cost less and range from $5 to $15 USD. While aftermarket seals may offer a comparable function, it is important to ensure they meet the same standards of quality and performance as OEM parts.
Bulk Purchase:
- Purchasing 1.1×4 oil seals in bulk can offer significant cost savings. Bulk prices for these seals typically range from $2 to $8 USD per seal, depending on the quantity ordered and the supplier.
Additional Costs:
- Shipping Costs: Depending on the location of the supplier, shipping fees can vary, especially for international orders.
- Labor Costs: If the oil seal is being replaced as part of a repair or maintenance service, labor costs will need to be factored in. Depending on the complexity of the replacement, labor costs can range from $50 to $150 USD per hour.
