Overview
The ReliaMark RMK 27353S BHRM is a precision oil seal engineered for bearing protection in industrial automation and power transmission equipment. ReliaMark seals are cost-effective alternatives designed for general-duty and MRO applications across a wide range of machinery. This specific model combines the reliability of a mounted bearing seal with dual-lip construction to protect against contaminants and oil loss.
Key Features
- Dual-lip design with garter spring for enhanced sealing performance
- Metal-backed BUNA elastomer lip for durability and chemical resistance
- Precision-ground outer diameter for accurate fits
- Suitable for general-duty bearing applications in production machinery
- Cost-effective MRO replacement option for frequently ordered sizes
- Available in new condition, ready for immediate installation
Technical Specifications
The seal meets industrial applications requiring protection from dust and oil leakage in bearing housings and mechanical power transmission systems. Typical operating temperatures range from standard industrial ambient conditions. The garter spring provides consistent lip pressure for reliable sealing across operating speed ranges.
Typical Applications
- Ball and roller bearing housings in industrial motors and gearboxes
- Mounted bearing protection in conveyor systems
- Machine tool spindle bearings and support bearings
- Agricultural and food processing equipment
- General industrial machinery requiring cost-effective sealing solutions
