A double row tapered roller bearing from TIMKEN packs two rows of tapered rollers into one assembly, so it takes radial and axial loads in both directions. Equipment that needs high load capacity and rigidity, such as gearboxes, mining machinery, rolling mills and heavy transmissions, is where this design is normally found. MR Industrial Accessories supplies this line and helps buyers match the right part number to the application.

Reading the designation G-3304-BPin helps when you are checking a bill of materials or an old nameplate. The G marks the series, 3304 sets the size position inside that family, and BPin points to a design variant, often tied to the cage, the sealing arrangement or how the rows are set. Other references in the TTHDFL series follow the same pattern: letters for the design, numbers for the dimensions. If a code is unclear, send it over and we will confirm the equivalent reference.

These bearings show up wherever combined loads meet moderate shaft speeds: cement plants, mining operations, steel mills, flour mills, material handling equipment and large gearboxes. Road machinery, cranes and power transmission systems that call for rigidity and long service also use them. Because the unit is double row, it can take the place of two single row bearings on one shaft, which simplifies the shaft design and frees up space.

Selection starts with the radial and axial load the bearing will carry, then the rotation speed, the lubrication method and the working environment. During mounting, keep the shaft and housing aligned, check internal clearance against the type of fit, and confirm the sealing is suitable when dust, water or contaminants are present. Grease or oil lubrication should follow the manufacturer's recommendation and be renewed according to service conditions. Cleaning the assembly before closing it helps prevent premature failures.

Double row tapered roller bearings are identified by their full designation, a mix of letters and numbers that varies by manufacturer. Diameter and width alone will not do, because contact angles, radii and tolerances change from one part number to the next. If your equipment carries another brand, send the original part number and we will point you to the compatible TIMKEN alternative or the option that best fits the application.
