The cone is the inner ring of a tapered roller bearing, the part that is mounted on the shaft and that, together with the cup, forms the assembly that withstands combined radial and axial loads. The TIMKEN JH series is used in applications where significant forces must be absorbed in a small space. MR Accesorios Industriales supplies this line in Buenos Aires, Argentina, and advises you on choosing the correct cone for your equipment.

The JH series designation is read with the letter J as a prefix and the H that identifies the cone type. The numbers that follow are the size code: JH211749, JH217249, JH307749 and JH415647 correspond to different shaft diameters and raceway widths. Each reference combines a cone with a specific cup; the number does not indicate dimensions by itself, so to identify the replacement part you must cross-reference the complete part number with the manufacturer's data sheet.

These cones are used in equipment where combined loads are the norm: speed reducers and gearboxes, conveyor rollers, construction machinery, earthmoving equipment, presses and machine tool spindles. In Argentina you will find them in cement plants, quarries, sugar mills, metalworking workshops and in the agro-industrial sector, especially in seeders and combine harvesters. They also appear in railway applications and in overhead cranes, where bearing reliability is critical.

To select the correct cone, take into account the radial and axial load it will withstand, the rotation speed and the type of lubrication. Mounting requires absolute cleanliness, checking the fit on the shaft and controlling axial clearance with the appropriate method: poorly adjusted clearance shortens bearing life. Alignment between cone and cup must be precise; if the assembly runs misaligned, the load concentrates at the ends of the rollers and premature failures appear. Sealing also matters: without an effective barrier, dust and moisture contaminate the grease and accelerate wear.

TIMKEN is a benchmark brand in tapered roller bearings, and there are equivalences with other brands that manufacture the same geometry. Interchangeability is not automatic: two cones with similar part numbers may differ in raceway angle or corner radius. Therefore, before replacing, always compare the critical dimensions and the cone and cup number as a set. If you cannot find the exact reference, at MR Accesorios Industriales we can point you to the compatible alternative.

If you need a cone from the JH series or any other bearing component, send us the part number on WhatsApp. At MR Accesorios Industriales we'll get back to you shortly with a quote and help you solve the application. We also carry housings, power transmission, seals, bushings, mounting tools and lubricants so your equipment keeps running.
