A TIMKEN LL…EC double row tapered roller bearing is a two-row unit that mounts on a single shaft. It takes radial and axial loads in both directions, so it suits arrangements where the load reverses. Typical uses include gearboxes, mining equipment and other heavy machinery. MR Industrial Accessories LLC supplies this line and can help you confirm the right configuration.

Reading the code helps you order the exact assembly. The LL prefix points to a double row tapered roller series with its own set of dimensions. The EC suffix describes a stamped steel cage and a contact angle that has been optimized. In a number such as LL771911EC, the middle digits set the size and geometry of the unit. With that full number you can request a quote by WhatsApp or email without back-and-forth.

These bearings show up in mining, cement, steel and earthmoving work. You will find them in speed reducers, gearboxes, support rollers, overhead cranes and crushing equipment. Because there are two rows, they absorb high radial loads and axial loads from either direction, which fits shafts that see load reversal. Road and agricultural machinery working in severe conditions also uses this type.

Selection comes down to the radial and axial load the bearing will carry, the rotation speed and the lubrication method. The LL…EC series accepts grease or oil, depending on how it is mounted. Shaft and housing alignment matters, since tapered rollers do not tolerate misalignment well. Choose sealing for the site: add extra seals where dust or moisture is present. Mount with a press or controlled heating, never with direct blows.

On equivalents, double row tapered roller bearings follow international standards, and several brands build similar configurations. Swapping a TIMKEN LL…EC for another make means comparing dimensions, contact angle and load capacity, not just the part number. MR Industrial Accessories LLC can point you to a compatible alternative or source the original number. Check tolerances and axial clearance before you install any equivalent.

If you need a TIMKEN double row tapered roller bearing, send the complete part number or the series designation by WhatsApp. We will quote promptly and help you choose the option that fits your equipment. If you only have the shaft and housing dimensions, send those and we can help identify the replacement.
