NTN J series tapered roller bearings are built to carry radial and axial loads in a single direction. The angled raceways and tapered rollers create linear contact that spreads the load across the bearing. You will find them in gearboxes, wheel hubs and other industrial machinery where precise, rigid motion is required. MR Industrial Accessories supplies this line and provides application support.

The part number tells you what you are holding. In the J series, the 4T- prefix marks a particular NTN execution. The following characters, such as in 4T-JH307749/JH307710, identify the cone and the cup. JH signals an inch-series tapered roller bearing, and the numeric suffixes set the dimensions and the contact angle. Every designation is unique and points to one exact bearing.

These bearings show up in food processing, metallurgy, mining and agriculture. They are common in milling equipment, conveyors, road machinery and support rollers. You will also find them in transmission cases and gearboxes that see variable loads. Dust, vibration and moderate temperatures are conditions they handle well.

Choosing the right bearing starts with the radial and axial load, the rotation speed and the lubrication method. Mounting demands precise alignment to prevent extra stress. Check the internal clearance and the sealing; if contaminants are present, add extra protection. Use a lubricant that matches the operating temperature, and follow the manufacturer's recommendations for shaft and housing fits.

Cross-brand equivalences exist for this bearing type, but always confirm dimensions and tolerances before substituting. NTN, SKF, Timken and others offer similar series, though suffixes can differ. If you have a part number from another brand, we can help you find the interchangeable one. The critical check is bore, outer diameter, width and contact angle.
