1. Product Advantages
- Dual-Spec Versatility: With dual outer diameter options (92mm/98mm) and a 35mm shaft fit, this seal eliminates the need for multiple inventory SKUs, reducing storage costs and streamlining installation for diverse equipment.
- Durable Sealing Performance: Made of high-quality rubber and reinforced skeleton structure, it resists wear, high temperature, and mechanical deformation, ensuring long-lasting protection against oil leakage and dust ingress.
- Cost-Effective Solution: Reduces equipment maintenance frequency and downtime, delivering excellent value for long-term industrial operations.
2. Working Principle
The box type oil seal relies on its precision-molded lip structure to form a tight contact with the rotating shaft. When the shaft operates, the lip adheres closely to the shaft surface, creating a dynamic sealing barrier. The reinforced skeleton enhances the seal’s structural stability, preventing deformation under pressure. Meanwhile, the seal’s design effectively blocks external contaminants (dust, debris) from entering the equipment while retaining internal lubricants, ensuring smooth operation of rotating components.
3. Product Details
- Model: 35×92/98×13/27
- Structure: Box type with metal skeleton reinforcement
- Material: Nitrile Rubber (NBR) as standard (customizable to Viton® for high-temperature needs)
- Precision Sizing: Strict dimensional tolerance control ensures perfect compatibility with target shafts and housing bores, avoiding installation gaps.
4. Application Range
This industrial-grade seal is widely applicable to:
- Heavy-duty machinery: Construction equipment, mining machinery, agricultural machinery
- Fluid handling equipment: Pumps, compressors, hydraulic systems
- Power transmission equipment: Motors, gearboxes, generators
5. FAQ
Q1: Can this seal be used in high-temperature environments?
A1: Our standard NBR seal works for temperatures ranging from -20℃ to 120℃. For higher temperatures (up to 200℃), we offer custom Viton® material options. Please contact our sales team for details.
Q2: What is the difference between the 92mm and 98mm outer diameters?
A2: The two outer diameter options are designed to fit different housing bore sizes of equipment, allowing one seal model to meet two installation requirements, optimizing inventory management.
Q3: How to ensure correct installation?
A3: Please clean the shaft and housing bore before installation, avoid sharp edges scratching the seal lip, and ensure the seal is fully seated in the bore without tilting.
