Industrial replacement parts for the paper industry
At MR Accesorios Industriales we supply components for paper machines: bearings, split plummer block housings, radial shaft seals, and lubrication systems. We address the demands of humidity, temperature, and high load in refiners, pumps, and dryers. With more than 80 years in the industry, we provide advice so that each piece of equipment runs continuously and safely. Request a quote by WhatsApp with the part number or application.
What the paper industry uses
Paper machines operate with wet rollers, dryers, refiners, and pumps under severe conditions: constant humidity, elevated temperatures, and combined loads. Bearings and housings must withstand misalignment and vibration without losing precision. Lubrication is critical because there are many points that require periodic attention. Therefore, components are selected for their sealing ability, corrosion resistance, and ease of maintenance, prioritizing production continuity.
For these machines, spherical roller bearings are used in roller and dryer shafts because they accommodate misalignment and high loads. CARB bearings are useful in sections with bending and thermal expansion. SNL split plummer block housings make mounting and dismounting easier on long shafts. Radial shaft seals (oil seals) protect against moisture and contamination. Centralized lubrication systems and greases and lubrication ensure each point receives the correct dose, reducing downtime.
When selecting, load, speed, temperature, and the humid environment are considered. Bearings with brass or polyamide cages and effective seals are preferred. During installation, the housings are aligned and internal clearance is checked. Lubrication must be suitable for high humidity and temperature, with scheduled inspections. Centralized systems make it possible to lubricate many points accurately, avoiding over- or under-lubrication that damages bearings.

Frequently asked questions
What bearings do you recommend for the wet rollers of a paper machine?
For wet rollers, spherical roller bearings are used, which accommodate misalignment and high loads. We also consider CARB bearings if there is bending. The choice depends on speed, temperature, and the sealing system. Contact us on WhatsApp with the equipment data.
How do radial shaft seals protect in such a humid environment?
Radial shaft seals prevent the entry of water and contaminants, protecting the bearing and lubrication. They are selected according to shaft type, speed, and temperature. It is essential to choose the appropriate material and design for each application.
Is it worth installing a centralized lubrication system in a paper plant?
Yes, because a paper machine has many lubrication points and centralized systems ensure precise doses and reduce the risk of failures due to incorrect lubrication. They also facilitate scheduled maintenance. Contact us to evaluate your case.
