Premium CR 40x68x7 Industrial Radial Shaft Seal | NBR Lip Seal for Rotating Equipment

Radial shaft seal 40X68X7, leveraging the heritage of CR Seals (Chicago Rawhide), is engineered for robust performance in demanding industrial applications. This standard metric seal features a high-grade Nitrile Butadiene Rubber (NBR) sealing lip reinforced by an internal garter spring, ensuring consistent radial load against the shaft surface. Designed to prevent the leakage of oil and grease while simultaneously blocking the ingress of dust, dirt, and moisture, this seal is essential for maintaining bearing integrity and extending the operational lifespan of gearboxes, pumps, and motors operating within standard temperature ranges. Selecting a premium sealing solution like the CR 40x68x7 significantly reduces the Total Cost of Ownership (TCO) by minimizing unplanned downtime and reducing maintenance intervention frequency. The precision-engineered lip geometry provides optimal friction characteristics, leading to lower heat generation and extended seal life compared to budget alternatives. This industrial-grade component is suitable for mineral oils, standard greases, and hydraulic fluids, making it the reliable choice for engineers focused on maximizing machinery uptime and adhering to stringent industrial reliability standards.

Key Features

  • Premium NBR (Nitrile) compound ensures compatibility with standard industrial oils and hydraulic fluids.
  • Integrated garter spring maintains continuous, uniform sealing force around the shaft.
  • Precision machined outer casing facilitates secure and easy press-fit installation into the bore.
  • Highly effective contaminant exclusion protects sensitive internal components and extends bearing life.
  • Durable construction designed for long service life in continuous rotating applications.
