The CR 1.688x2.688x0.500 SYN NBR Oil Seal (Part No. CR-16559) is engineered for rotating equipment requiring dependable sealing performance under normal industrial operating conditions. It is suitable for OEM machinery as well as maintenance and overhaul applications across manufacturing, mining, agriculture, construction, and general industrial sectors.

Manufactured by Chicago Rawhide (CR), one of the world's most recognized sealing technology brands, this oil seal utilizes precision sealing geometry together with premium Synthetic NBR elastomer to provide long-lasting sealing performance.

The seal incorporates a spring-loaded primary sealing lip that continuously maintains radial contact pressure against the rotating shaft through an integrated garter spring. This design minimizes lubricant leakage while protecting bearings, gears, shafts, and internal rotating components.

The reinforced metal case provides excellent dimensional stability and secure housing retention. Under normal operating conditions, seals of this construction are generally suitable for applications with internal pressure up to approximately 0.5 Bar, depending on shaft speed, lubrication, and installation quality.

Manufactured from premium Synthetic NBR (Nitrile Butadiene Rubber), the seal provides excellent resistance to:

• Mineral oils
• Hydraulic oils
• Gear oils
• Lubricating grease
• Petroleum-based lubricants
• Light industrial chemicals

Synthetic NBR offers excellent abrasion resistance, flexibility, aging resistance, and cost-effective sealing performance. Typical operating temperatures range from -40°C to +100°C, depending on lubricant compatibility and operating conditions.

With dimensions of 1.688 × 2.688 × 0.500 inch, this oil seal is commonly installed in industrial pumps, speed reducers, gearboxes, compressors, agricultural machinery, conveyor systems, construction equipment, and OEM rotating machinery utilizing inch-size shaft systems.
