The NTN 4T series tapered roller bearing handles combined radial and axial loads, with a geometry that provides high load capacity. It is commonly found in gearboxes, wheel hubs, and other industrial machinery where rigidity and precision matter. MR Industrial Accessories LLC supplies this series and supports each request with technical guidance and a fast quote.
The 4T series part number follows a pattern: the 4T prefix denotes a high-capacity tapered roller bearing, JHM indicates the dimension series, and the two numbers separated by a slash identify the cone and the cup. Suffixes can signal differences in contact angle, internal design, or heat treatment. Reading these codes correctly helps you match the bearing to the application.
These bearings are used in gearboxes and reducers, machine tool spindles, conveyor rollers, and wheel hubs in automotive and railway equipment. They also appear in food, cement, and mining operations where load and speed conditions call for robust components. Their ability to take combined loads suits arrangements with simultaneous radial and axial forces.
Selection depends on the mounting arrangement, sealing, and lubrication. Tapered roller bearings are often mounted in pairs with controlled axial clearance set by the application. Alignment between the cone and the cup is critical to avoid premature wear. Grease or oil lubrication can be used, and the sealing choice follows the working environment. We can help you define the right configuration.
When replacing a tapered roller bearing, interbrand equivalences are common. Standardized dimensions allow interchangeability even though each manufacturer uses its own nomenclature. If you have another brand's code, we can identify the equivalent NTN reference. Contact us with the code or main dimensions via WhatsApp or email, and we will reply promptly with options.

Frequently asked questions
- What does the 4T designation mean in NTN bearings?
- The 4T prefix identifies high-capacity tapered roller bearings in the NTN catalog. It indicates a design made to support combined radial and axial loads.
- How do I choose between a single-row and a double-row bearing?
- The choice depends on load magnitude and available space. Single-row bearings suit moderate loads and simple mountings; double-row bearings offer greater load capacity and rigidity but require more complex mounting. We can advise based on your application.
- Can I replace a bearing from another brand with an NTN 4T series bearing?
- Yes, if dimensions and load capacity are equivalent. Provide the original brand's code and we can identify the corresponding NTN reference. Verify contact angle and internal design for proper operation.
