What types of NTN tapered roller bearings does 3G Electric supply?

3G Electric supplies NTN tapered roller bearing cones, cups, and complete assemblies in both inch and metric systems. Examples include the 4T-05062 cone with a 5/8 in bore and 1.67 in OD, and the 33213 assembly with a 65 mm bore and 120 mm OD. These bearings feature carbon steel rings and pressed steel cages, and are designed to handle combined radial and axial loads. The product range covers bore sizes from 5/8 in to 6 11/16 in, with various width and diameter combinations to suit different shaft and housing requirements.

What are the specifications of NTN pillow block ball bearings available from 3G Electric?

NTN pillow block ball bearings from 3G Electric, such as the UCPL-1.3/16M, feature cast iron housings with set screw locking. The bore is 1 3/16 in, shaft height is 1 9/16 in, and maximum speed is 5,900 RPM. Mounting bolt size is 1/2 in. These units are suitable for supporting rotating shafts in material handling, conveyors, and similar applications. They are available in inch and metric sizes, with various locking methods and housing configurations to accommodate different mounting needs.

How can I identify the correct NTN tapered roller bearing assembly for my application?

To identify the correct NTN tapered roller bearing assembly, refer to the bearing's part number, which typically consists of a cone number and a cup number, such as LM814849/LM814810. The part number indicates the bore, outside diameter, and width dimensions. For inch-system bearings, the bore is often given in inches, while metric bearings use millimeters. 3G Electric provides detailed specifications for each SKU, including bore, OD, cone width, cup width, and cage material. Cross-reference the existing bearing's part number or measure the shaft and housing dimensions to select the appropriate assembly.

What materials are used in NTN tapered roller bearings?

NTN tapered roller bearings typically use carbon steel for the rings (cone and cup) and pressed steel for the cage. Some series may use chrome steel for the cage, depending on the specific model. For example, the 4T-05062 cone has a chrome steel cage and carbon steel ring. These materials provide a balance of strength, wear resistance, and cost-effectiveness for industrial applications. The bearings are designed to operate under combined radial and axial loads, with lubrication and maintenance practices influencing service life.

Does 3G Electric offer NTN bearings in both inch and metric sizes?

Yes, 3G Electric stocks NTN bearings in both inch and metric systems. The product range includes inch-system tapered roller bearing assemblies like LM29748/LM29710 with a 1 1/2 in bore, and metric assemblies like 33213 with a 65 mm bore. This dual availability ensures compatibility with equipment from various regions and manufacturers. The catalog includes detailed specifications for each bearing, allowing customers to select the correct size and configuration for their specific application, whether it requires inch or metric dimensions.

What is the maximum speed for NTN pillow block ball bearings?

NTN pillow block ball bearings, such as the UCPL-1.3/16M, have a maximum speed of 5,900 RPM. This speed rating is dependent on factors such as lubrication, load, and operating temperature. For applications requiring higher speeds, consider other NTN bearing types or consult technical documentation. The maximum speed is a critical parameter for ensuring reliable operation and preventing overheating or premature failure. 3G Electric provides this specification for each pillow block unit to aid in selection.
