Bearings and power transmission for the cement industry
At MR Accesorios Industriales, we supply components for the cement industry: spherical roller bearings, SAF and SNL split plummer block housings, roller chains, pulleys (sheaves), couplings, and centralized lubrication systems. With more than 80 years of experience, we understand the demands of rotary kilns, mills, bucket elevators, and belt conveyors, where fine abrasive dust and continuous loads punish every part. We support cement plants nationwide with technical advice and fast quotes via WhatsApp.
What the cement industry uses
The cement industry operates with machines subjected to continuous loads and fine abrasive dust. Rotary kilns rotate without pause and require bearings and housings that withstand temperature and misalignment. Ball mills and vertical mills work with impacts and constant vibration. Bucket elevators and belt conveyors move bulk material, with shafts that suffer misalignment due to settlement and thermal expansion. In all this equipment, component selection and lubrication make the difference between a planned shutdown and an unexpected failure.
For this equipment, spherical roller bearings are the natural choice on shafts with bending and misalignment, because they accommodate small angles without losing load capacity. They are mounted in SAF split plummer block housings and SNL, which make mounting and inspection easier without disassembling the entire equipment. In power transmission, roller chains and pulleys (sheaves) move elevators and conveyors, while couplings absorb misalignment between motor and gearbox. Centralized lubrication systems ensure that each critical point receives lubricant constantly, which is key with abrasive dust.
When selecting, load type, speed, temperature, and contamination level are evaluated. In environments with fine dust, effective seals and centralized lubrication are prioritized to prevent abrasive particles from entering the bearings. Mounting split plummer block housings requires careful alignment and correct tightening of bolts; chains need proper tension and pulleys require groove alignment. Lubrication must be suitable for high load and temperature, with defined intervals according to the equipment. These general criteria are adjusted to each application with our advice.
Working with MR is simple: send us the component part number or tell us the application and we will advise you. We quote via WhatsApp and coordinate shipments nationwide. With more than 80 years in the industry, we understand the needs of cement plants and help you choose the right component for each machine.

Frequently asked questions
What bearings are suitable for rotary kilns?
For rotary kilns, spherical roller bearings are usually used, which withstand high loads and misalignment due to thermal expansion. They are mounted in SAF or SNL split plummer block housings to facilitate maintenance. The final choice depends on the load, speed, and temperature of each piece of equipment.
How do you protect bearings from abrasive dust in mills?
The key is to combine effective seals with a centralized lubrication system that maintains internal pressure and renews the lubricant. It is also recommended to use well-sealed split plummer block housings and periodic inspections to detect the entry of contaminants.
What criteria should I consider for selecting chains and pulleys?
You need to evaluate the transmitted load, speed, service type, and environmental conditions. In cement plants, where there is dust and continuous loads, robust roller chains and pulleys with aligned grooves are prioritized. Technical advice helps define the best option.
