SB Oil Seal

SB Oil Seals are designed with a single sealing lip and no garter spring, providing a simple and cost-effective solution for basic sealing requirements. Materials available include NBR for general oil sealing and FKM for higher temperature and chemical resistance.

They are suitable for low-pressure and low-speed rotating equipment, such as light-duty machinery and agricultural equipment, where stable operating conditions and minimal contamination are present.

Key Features

• Single lip design for basic oil sealing
• No spring structure, suitable for low-load conditions
• Cost-effective solution for simple applications
• Easy installation and simple structure
• Suitable for low-speed and low-pressure environments

Technical Specifications

• Type: SB (Single Lip without Spring)
• Material: NBR / FKM available
• Temperature Range: NBR -30°C to +100°C, FKM -20°C to +200°C

Size Range

Standard and custom sizes available. Custom inner diameter (ID), outer diameter (OD), and width supported based on drawings or samples.

Applications

• Light-duty machinery
• Low-speed rotating equipment
• Agricultural equipment
• General-purpose sealing
• Equipment with low pressure and minimal contamination

Material Advantages

NBR (Nitrile Rubber) offers general oil resistance and cost-effectiveness, while FKM (Viton® equivalent) provides higher temperature and chemical resistance for more demanding environments.
