Description
TIMKEN LM520310D belongs to tapered roller bearing de doble hilera, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for LM520310D and any equivalents.
TIMKEN double row tapered roller bearings pack two rows of tapered rollers into one mounting. They handle radial and axial loads in both directions, so they suit gearboxes, machine tool spindles and mining equipment where space is tight and support must be rigid.
The part number tells you a lot. Take LM119311D, LM119348D and LM241110D: the LM prefix and the D suffix belong to the double row family in the TIMKEN catalogue. Series such as TDO, TDI or TNASWE describe how the assembly is built—two cones, two cups or a mix. Give us the full number and we can pin down the exact reference.
You will see these bearings in mining, cement, steel and food plants, as well as in speed reducers, mills, conveyor belts, presses and earthmoving machines. Because one double row unit does the job of two single row bearings, shaft design gets simpler and you need fewer mounting parts.
When selecting, look at radial and axial load, speed and the environment. Sealing matters: dusty or damp conditions call for extra protection. Lubrication has to match the application, and mounting demands precise alignment with a fit that sets the right internal clearance. Poor mounting shortens bearing life.
TIMKEN tapered roller bearings can replace other brands if the main dimensions and contact angle line up. Every maker uses its own nomenclature, so equivalence comes from comparing dimensions and load ratings. Send us the original part number and we will point you to a compatible option.
We supply the TIMKEN double row tapered roller bearing line. If you need an LM series reference with a D suffix, message us on WhatsApp or email with the part number. Our team replies promptly and can also help with mounting and lubrication questions.

Frequently asked questions
- What does the D suffix mean in the LM series?
- In TIMKEN designations, the D suffix marks double row assemblies. These combine two rows of tapered rollers in one mounting, so they take radial and axial loads in both directions and offer more capacity than a single row bearing.
- How do I request a quote for a TIMKEN bearing?
- Send the complete part number, such as LM119311D or LM241110D, via WhatsApp or email. We will quote it promptly and suggest a compatible alternative if needed.
- What should I consider for mounting?
- Respect shaft alignment, the fit and the internal clearance recommended by the manufacturer. Lubrication must suit the working speed and temperature. Incorrect mounting can cause premature failures and shorten bearing life.
