The CR Oil Seal 2.313x3.002x0.406 M/R NBR (Part Number CR-23300) is designed to deliver dependable sealing performance in rotating equipment where lubricant retention and contamination exclusion are critical to operational reliability.

The M/R Profile combines a reinforced metal outer case with a precision-engineered sealing lip and garter spring assembly. This robust construction ensures dimensional stability while maintaining consistent sealing pressure against the shaft surface under continuous operation, vibration, and varying load conditions.

The spring-loaded sealing lip helps prevent oil leakage while protecting bearings, shafts, and internal components from dust, dirt, moisture, and environmental contaminants. This contributes to extended equipment life and reduced maintenance requirements.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the sealing element offers excellent resistance to lubricating oils, hydraulic fluids, gear oils, grease, and petroleum-based lubricants. NBR is widely used throughout the industrial sector because of its excellent balance of oil resistance, wear resistance, flexibility, and cost-effective performance.

With dimensions of 2.313 x 3.002 x 0.406 inch, this oil seal is commonly found in industrial pumps, gearboxes, agricultural equipment, compressors, conveyor systems, hydraulic drives, and imported machinery using inch-sized shaft configurations.

CR (Chicago Rawhide) oil seals are recognized globally for delivering high-quality sealing solutions for industrial maintenance, equipment rebuilding, and OEM applications.
