For more than 126 years, the Dodge brand has been synonymous with the top products in the industry. Its housed bearings are recognized by global users as the highest quality products in the industry. These high-quality features are further carried forward on the full range of Dodge ISN spherical roller bearings. This patented system not only provides a concentric tightening force to clamp the bearing on the shaft, but also ensures that the bearing can be disassembled and assembled within 15 minutes. Combine these excellent features with the high-quality sealing system of the ISN series bearings and a wide variety of compact one-piece, industry-standard housings, and you have a range of high-quality, high-end housed roller bearings. Original Dodge ISN series spherical roller bearing with seat TRIDENT seal ring Labyrinth seal ring ISN series spherical roller bearing with seat Patented ISN push-pull disassembly system; 360 uniform force, full contact, reducing or eliminating friction and corrosion; no need for feeler gauges ; Easy disassembly; Floating and fixed bearings can be easily converted on site; Triple-lip contact seals for wet and dirty applications; Non-contact labyrinth seals for high-speed, high-temperature applications. Patented Sealing Technology Ineffective seals can allow contaminants to enter the inside of the bearing, causing the bearing to fail. However, the ISN bearing core has two unique seal rings for maximum seal protection. Our proven Trident seals are ideal for dirty environments, low to medium speeds or normal service. This triple-lip contact seal is made of nitrile material and has a low coefficient of friction, allowing the sealing surface to cover the entire sealing contact area, even when misaligned. For higher speeds and harsher conditions, ISN bearing cores offer labyrinth seals with corrosion-resistant oil rings and steel gap seals. Time-saving removal and replacement design 1) Steel cage provides precision roller guidance; 2) Composite guide rings are sleeved on the bearing outer ring to minimize heat generation; 3) Cone sealing surface covers the entire contact surface when misaligned; 4) Patented nitrile triple-lip seal , heat resistance and chemical corrosion resistance; 5) Patented push-pull loading and unloading system, easy to disassemble; 6) Push-pull bushing improves coaxiality and suppresses vibration.
