Bearings and seals for the marine industry
At MR Accesorios Industriales, we supply components for the naval industry: bearings, bearing housings, seals, couplings and lubricants designed for winches, shaft lines, pumps, and ventilation and deck systems. With over 80 years in the industry, we understand the demands of saltwater environments and the need for fast replacement in port. We advise you so you can choose the right part and request a quote via WhatsApp.

What the marine industry uses
The naval industry operates with cargo and handling winches, shaft lines, bilge and transfer pumps, and ventilation and deck systems. The saltwater environment attacks everything: humidity, splashes and condensation accelerate corrosion and degrade lubricants. On top of that, there is the urgency of replacement in port, where every hour of downtime counts. That is why components must resist corrosion, withstand variable loads and allow agile installation, without complicated adjustments or special tools.
For winches and shaft lines, spherical roller bearings are used, which tolerate misalignment and combined loads. In pumps and ventilation, stainless steel deep groove ball bearings offer corrosion resistance. SNL split plummer block housings facilitate installation and inspection on long shafts. Radial shaft seals (oil seals) keep out moisture and prevent lubricant leaks. Couplings absorb vibrations and compensate for small misalignments between motor and gearbox. Greases and lubrication specific to marine environments protect against saltwater and oxidation.
When selecting, consider load, speed, temperature and the level of salt exposure. For shafts with flexing or misalignment, spherical roller bearings are the choice; for pumps and auxiliary equipment, stainless steel bearings. Split plummer block housings simplify maintenance without disassembling the shaft line. During installation, check alignment and adjustment of the radial shaft seals, and choose greases with corrosion inhibitors. Periodic lubrication and contamination control extend service life. If in doubt, our technical team will guide you based on the application.
Working with MR is simple: request a quote via WhatsApp by indicating the part number or describing the application and equipment. We advise you to choose the best option according to the naval environment. We ship nationwide with the speed the industry needs. With over 80 years of experience, we support workshops, shipyards and shipowners with reliable components and personalized service.

Frequently asked questions
What bearing is best for a winch shaft subjected to variable loads?
For winches, spherical roller bearings are suitable because they tolerate misalignment and combined loads. We evaluate load and speed to recommend the correct type and size. Request a quote via WhatsApp with the equipment data.
Do you have radial shaft seals that withstand saltwater environments?
Yes, we have radial shaft seals manufactured with materials resistant to corrosion and saltwater. It is key to check fit and lubrication to extend their service life. Contact us with the size or part number.
