Timken HSM series split housings are two-half housings that wrap around split cylindrical roller bearings. They are used when the shaft cannot be disassembled: they open, are mounted over the already installed bearing and fastened with bolts. MR Accesorios Industriales carries them in Buenos Aires, Argentina, for continuous process equipment where every hour of downtime counts.
The HSM series designation is read with the fixed prefix and a number that indicates the housing size: HSM280, HSM300, HSM320, HSM340, HSM360, HSM380, HSM400 and HSM420 are the sizes that make up the series. That number is not a shaft diameter or a mounting dimension: it identifies the housing within the family. To choose the right one, what matters is the split bearing that is housed and the shaft dimensions. Send the complete part number and from MR we'll quote you the exact reference.
These housings are found in belt conveyors, bucket elevators, mills, mixers, high-flow pumps and equipment in mining, cement, paper, sugar and aggregate processing. In Argentine plants where the shaft is coupled to gearboxes, pulleys or couplings that are not easy to disassemble, the split housing avoids moving the entire line: the upper half is removed, the bearing is replaced and it is closed again. That is the reason they are chosen for corrective maintenance and critical equipment.
To select correctly, verify that the housing corresponds to the split bearing you are going to mount and to the shaft diameter. Check the condition of the shaft surface: a worn or burred seat accelerates the failure of the new bearing. During installation, clean the joint faces of the two halves, apply the bolt torque in a cross pattern and check alignment with the shaft. Bearing lubrication and housing sealing are key: without clean grease and without seals in good condition, any housing fails.
On the market there are split housings from several brands that can perform the same function, but they are not interchangeable piece by piece: tolerances, fastening systems and seals change. The Timken HSM series responds to the geometry of that brand's split bearings. If you need to replace a housing of another origin, write to us with the old part number and the shaft dimensions: we'll indicate the compatible alternative or, if none exists, we manufacture it to measure.
MR Accesorios Industriales carries the Timken HSM series in Buenos Aires, Argentina, with more than 80 years of experience in bearings, housings and power transmission. If you have the housing part number or that of the split bearing, send it on WhatsApp: we'll quote you shortly. If you're looking for a variant you don't see, write to us with the model you need and we'll indicate how to proceed.

Frequently Asked Questions
- What does the number in an HSM280 or HSM320 housing mean?
- The final number identifies the housing size within the HSM series. It is not the shaft diameter or a mounting dimension. To choose the right one it must be cross-referenced with the split bearing that is housed and with the shaft dimensions. Send us both data and we'll quote you.
- Can an HSM housing be mounted without disassembling the shaft?
- Yes. The split housing is designed for that: it opens into two halves, is placed over the bearing already installed on the shaft and is closed with bolts. It is the solution when the shaft is coupled to gearboxes, pulleys or equipment that cannot be moved. Verify alignment and closing torque.
- How do I request a quote for an HSM housing?
- Write to us on WhatsApp with the complete housing part number (for example, HSM300) and, if you can, the part number of the split bearing that goes inside. With that data we'll quote you shortly. If you don't have the part number, send us the shaft dimensions and a photo of the housing.
