The NTN 4T-HM212047 is a tapered roller bearing cone (inner race) with a 2.5-inch inner diameter, designed to manage combined radial and axial loads in demanding applications such as axles, hubs, gear drives, and powertrain systems. When paired with a compatible cup—such as NTN 4T-HM212011—it forms a durable bearing set suitable for both OEM installations and replacements.
Manufactured from high-quality alloy bearing steel, this cone features precision-machined tapered rollers and raceways, delivering excellent load distribution, reduced friction, and extended bearing life, even in high-impact or high-speed environments.
Ideal for use in automotive, agricultural, construction, and industrial machinery, the NTN 4T-HM212047 is engineered to meet strict OEM and industry standards, ensuring reliable performance under continuous or shock-loaded conditions.
Choose the NTN 4T-HM212047 for exceptional strength, consistent fit, and long-lasting performance in critical mechanical systems.
