NTN tapered roller bearings are engineered to handle radial and axial loads at the same time. Their cone-and-cup design creates a linear contact path that spreads the load across the raceway. You will find them in gearboxes, wheel axles, and agricultural machinery—anywhere forces are high and some misalignment is acceptable. MR Industrial Accessories supplies these bearings; just send the part number or dimensions and we will get you a quote.
The 329 series covers single-row tapered roller bearings, and the basic number tells you the size. Part numbers like 32910, 32924, 32926, 32920, and 32938 all belong to this series. When a prefix such as ○ appears, it typically indicates a variant in finish or tolerance set by the manufacturer. To match the right bearing, provide the full part number or the shaft and housing dimensions.
These bearings show up in food processing, metallurgy, mining, and agro-industry equipment. They are common in gearboxes, pumps, fans, conveyors, and earthmoving machines. Automotive and railway applications also rely on them. Because they take combined loads, they suit shafts that transmit power and see axial forces.
Selection depends on several factors. Consider the sealing type—open, shielded, or sealed—based on the working environment. Lubrication must be appropriate, and mounting requires precise alignment to avoid extra loads. Internal clearance and preload affect performance and service life. In vibrating or shock-heavy equipment, check the tolerance class. Our team can help you define the right configuration.
If you are replacing a bearing from another brand, we can find an equivalent. Just send the complete part number or the main dimensions: shaft diameter, outer diameter, and width. With that information, we will suggest a compatible alternative or supply the exact part. We work with leading brands and respond quickly with a quote.
