Professional O-Ring and Oil Seal Manufacturer, Sealing Solution Supplier Since 2008.
R35 Heavy-Duty Oil Seal: Anti-Leak, Wear-Resistant, FKM/NBR
Ideal for Rolling Mills, Wind Power & Heavy Machinery
The R35 heavy-duty oil seal is a high-performance sealing component engineered for harsh industrial environments. It boasts a robust structure with fabric-reinforced shoulders integrated with sealing lips, preloaded by a spring to maintain consistent radial pressure. Constructed from either nitrile rubber (NBR) with nitrile fabric or fluoroelastomer (FKM) with fluoroelastomer fabric, it offers excellent wear resistance and temperature adaptability (up to 100°C for NBR, 180°C for FKM). Ideal for applications like rolling mills, wind power equipment, and shipbuilding transmission systems, it ensures reliable leakage prevention even under pulsating pressures. Easy to install and built for durability, it provides long-term, dependable sealing protection for critical machinery operations.

Product Advantages
Excellent Sealing Performance: Forever Seals' R35 heavy-duty oil seal adopts a spring preload design, enabling the sealing lip to maintain stable radial pressure at all times. It can effectively prevent leakage of lubricating oil or other fluids, and maintain reliable sealing even under pulsating pressure environments, providing a solid guarantee for the stable operation of equipment.
Superior Wear Resistance and Durability: Made of nitrile rubber (NBR) + nitrile fabric or fluoroelastomer (FKM) + fluoroelastomer fabric, Forever Seals' R35 oil seal features a fabric-reinforced structure that greatly enhances overall strength and wear resistance, prolonging service life and reducing replacement frequency and maintenance costs.
Good Temperature Adaptability: Forever Seals offers material options tailored to temperature needs: nitrile rubber for stable work below 100°C, and fluoroelastomer for adaptation to high-temperature environments below 180°C, meeting different working condition requirements.
Easy Installation: Forever Seals designs the product with installation convenience in mind, featuring a compact and reasonable structure. Operators can quickly complete installation without complex professional skills, improving work efficiency.
Product Working Principle
Forever Seals' R35 heavy-duty oil seal achieves sealing through its unique structure. The fabric-reinforced shoulder is tightly integrated with the rubber sealing lip, and the spring provides continuous preload force to the sealing lip, making it tightly fit the rotating shaft surface, forming an effective sealing barrier. When the shaft rotates, contact pressure between the sealing lip and the shaft prevents fluid leakage through gaps and blocks external impurities, ensuring normal equipment operation.
Product Details
Material Selection: Forever Seals strictly selects high-quality nitrile rubber, nitrile fabric, fluoroelastomer, and fluoroelastomer fabric to ensure material stability and performance, guaranteeing product quality from the source.
Structural Design: The fabric-reinforced outer shoulder enhances the oil seal's overall rigidity, preventing deformation during installation and work; the spring's precise installation position and force setting ensure uniform and continuous pressure on the sealing lip—hallmarks of Forever Seals' engineering.
Dimensional Accuracy: Forever Seals subjects the product to precision machining, controlling dimensional errors within a very small range to ensure a good fit with equipment, guaranteeing sealing effect and smooth installation.
Application Range
Forever Seals' R35 heavy-duty oil seal is widely used in various heavy machinery and transmission systems, mainly including steel mill rolling mills (such as pomini, danieli and other imported rolling mills), shipbuilding equipment, wind power generation equipment, grinding machines, etc. In these equipment's transmission parts, it effectively copes with harsh working environments and plays a reliable sealing role.
FAQ (Frequently Asked Questions)
Q: How to choose between the nitrile rubber and fluoroelastomer materials of Forever Seals' R35 heavy-duty oil seal?
A: Selection is based on working environment temperature. For temperatures below 100°C, nitrile rubber (NBR) + nitrile fabric is sufficient; for 100°C-180°C, fluoroelastomer (FKM) + fluoroelastomer fabric is recommended.
Q: Are there special installation requirements for Forever Seals' R35 heavy-duty oil seal?
A: During installation, ensure the oil seal and shaft mating surface is clean and impurity-free to avoid scratching the sealing lip; also, ensure proper installation so the oil seal's shoulder closely attaches to the equipment's installation groove for optimal sealing—guidelines provided by Forever Seals.
Q: What is the general service life of Forever Seals' R35 oil seal?
A: Service life depends on working environment, temperature, pressure, and sealed fluid. Under normal conditions, it ensures a long service life. Forever Seals recommends regular inspection and replacement based on actual usage.
