Bearings and Housings for the Cement Industry: Mills, Kilns, Fans, and Transport

Cement production imposes severe conditions on mechanical components: heavy loads, low or medium speeds, high temperatures near the kiln, and constant presence of abrasive dust. Bearings for cement plants must withstand impacts, misalignments, and contamination without losing reliability.

At MR Accesorios Industriales, we work with bearings and housings suitable for each stage of the process: from limestone crushing to final grinding and dispatch. We distribute recognized brands such as SKF, FAG, and Link-Belt, and we advise you to choose the correct reference according to the application.

If you are in Buenos Aires, Argentina, you can get a quote via WhatsApp or email by sending the bearing code, dimensions, or a photo of the part. We will respond promptly with the most convenient option.

Ball mills and rotary kilns mainly use spherical roller bearings, which accommodate shaft misalignments and combined radial and axial loads. They are ideal for free and fixed supports on mill trunnions and kiln support stations.

In our catalog you will find references such as 22325 and 22361 from SKF, 20222-MB and 20240-MB from FAG, and 6203U and 22318 from Link-Belt. All correspond to the Spherical Roller Bearings subcategory, with double-row design and machined or sheet metal cage depending on the model.

When selecting a spherical roller bearing for a cement plant, consider the internal clearance (usually C3 or C4 due to high temperatures) and the lubrication system. If you have doubts, send us the current reference and we will indicate the equivalent alternative.

Split housings (also called pillow blocks) are the standard option for mounting bearings on mill, fan, and conveyor shafts. Their split design facilitates assembly, inspection, and replacement without disassembling the entire equipment.

We work with SAF and SNL housings from SKF, such as SAF 322, SAF 520, SNL 211, and SNL 216. These housings are combined with spherical roller or ball bearings with adapter sleeves, and can include seals for dusty environments.

For the cement industry, we recommend housings with a robust base and reinforced cap, capable of absorbing vibrations and maintaining alignment. If you need to replace an existing housing, indicate the code engraved on the housing or the shaft dimensions and we will quote the complete assembly.

Chain conveyors, bucket elevators, and mill feeders depend on roller chains resistant to wear and load. In the cement industry, large-pitch chains, single or multiple strand, with hardened links are used.

We distribute SKF chains such as PHC 81X-O/L and PHC 40-2C/L, Tsubaki chains such as RS60 and RS25, and Emmar chains such as 12-C1 and 10-C2. All correspond to the Roller Chains subcategory and are available in different pitches and configurations.

When quoting a chain, verify the pitch, inner width, and number of strands. If you do not have the code, measure the distance between pins and the link width, or send us a photo with a ruler next to it. We help you identify the correct model.

Induced draft fans, dynamic separators, and pumps in the cement plant require reliable transmissions. V-belt pulleys and elastic or gear couplings ensure power transfer without excessive vibrations.

At MR Accesorios Industriales, we work with cast iron and steel pulleys, in taper bushing or cylindrical bore versions, and couplings of different types according to the application. Although we do not list specific codes in this article, you can inquire by dimensions and we will quote the appropriate option.

To select a pulley, we need the pitch diameter, number of grooves, and bushing type. For couplings, the shaft diameters and torque to be transmitted. Send us that data via WhatsApp or email and we will respond with the proposal.

Lubrication is critical in the cement industry: a poorly lubricated bearing fails prematurely and stops production. Centralized lubrication systems dose grease or oil at multiple points automatically, reducing downtime and human errors.

We offer centralized lubrication systems from recognized brands, with pumps, distributors, and accessories for custom configurations. These systems are ideal for mills, kilns, and conveyors where manual access is difficult or dangerous.

If you are evaluating automating lubrication in your plant, consult us about available components. We advise you on the circuit design and quote the necessary elements according to the number of points and the type of lubricant.

To get a quote for any bearing, housing, chain, pulley, or lubrication system for your cement plant, write to us via WhatsApp or email. Send us the part code (for example, 22325 or SAF 322), main dimensions, or a clear photo of the part.

Our technical-commercial team will respond promptly with the available option and the corresponding price. We ship throughout the country from Buenos Aires, Argentina.

Do not hesitate to consult us for cross-brand equivalences or longer-lasting alternatives. We are here to help you keep your plant running.
