TIMKEN HM318448XS is a tapered roller bearing de doble hilera reference, within Bearings. Request a quote for HM318448XS via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.

TIMKEN SR series tapered roller bearings are double row units that combine two cones and a common cup, designed to withstand radial and axial loads in both directions within a single housing. They are used where rigidity and load capacity are needed in a small space, such as gearboxes, road machinery drives and power transmission equipment. MR Accesorios Industriales supplies them in Buenos Aires, Argentina, with over 80 years of experience in the industry.

The designation of these bearings is read in blocks: the initial letters identify the series and the number following the base code defines the size. In the SR series, the XS suffixes appear in references such as HM318448XS, HM516849XS, HM522649XS and HM807045XS, where the combination of letters and numbers follows TIMKEN nomenclature for double row assemblies. To choose the correct replacement, the safest approach is to provide the complete code as it appears on the drawing or on the old part.

These bearings are used in industries in Argentina where there are combined loads and shafts rotating at moderate speeds: cement plants, mining, steel mills, earthmoving, mills and power transmission equipment. They also appear in gearboxes, heavy conveyor rollers and agricultural machinery. In all these cases, the double row allows replacing two single row bearings with a single unit, simplifying assembly and improving the rigidity of the assembly.

When selecting and mounting a double row tapered roller bearing, take into account sealing, internal clearance and lubrication. These assemblies usually operate with controlled clearance and require careful alignment between shaft and housing, because any misalignment concentrates the load on the roller ends. Lubrication can be grease or oil depending on the equipment, and sealing must protect against dust and moisture. When in doubt, consult the machine manual or the gearbox nameplate.

Regarding equivalents, tapered roller bearings are identified by their designation and main dimensions, not by the manufacturer's name. Interchangeability between brands may exist if the bore diameter, outer diameter and width match, but internal suffixes vary from one manufacturer to another and affect clearance and sealing. Therefore, when looking for an alternative, provide the complete code and housing dimensions so that MR Accesorios Industriales can indicate the compatible option.

If you need a quote for a TIMKEN SR series tapered bearing, send the code via WhatsApp to MR. With the code or model on your equipment, we will quote it promptly and indicate the compatible alternative if needed. We can also advise you on mounting, lubrication and care so that the bearing operates under the correct conditions.
