NTN HM 88542/10 31.75x73.02x29.37 mm Tapered Roller Bearing

Specifications & Technical Profile

Heavy-Duty Tapered Roller Bearing Unit for Industrial Use

The NTN HM 88542/10 is a single-row tapered roller bearing set with bore 31.75 mm, outer diameter 73.02 mm and a total width of 29.37 mm. Engineered for high-load applications, this bearing delivers robust radial and axial load capacity in both directions. The assembly consists of a tapered inner cone with rollers and a matched outer cup, forming a complete bearing unit ready for mounting in housings or shafts where reliability, stiffness and precision are required.

Key Advantages and Applications

Robust Construction, High Load Capacity, Industrial Versatility

• High load-bearing capacity — The tapered roller design distributes loads evenly across rollers and raceways, enabling excellent resistance to heavy radial and combined loads under demanding conditions.

• Durable and long-lasting — Manufactured from high-grade hardened steel, the bearing delivers longevity and consistent performance even under continuous operating cycles, vibrations or shock loads.

• Ready-to-install bearing unit — Delivered as a complete assembly (inner tapered unit + outer cup) for quick installation in bearing housings or shafts, minimizing assembly time and reducing risk of incorrect mounting.

• Versatile industrial applications — Ideal for gearboxes, drive axles, heavy-duty machinery, agricultural or construction equipment, transmissions, differentials, axles, conveyors and various mechanical assemblies requiring a sturdy tapered roller bearing.

• Precision and stability — The design ensures minimal deflection under load, stable shaft alignment and smooth operation, contributing to lower maintenance needs and improved uptime in industrial environments.

Detailed Description

The NTN HM 88542/10 (31.75x73.02x29.37 mm) tapered roller bearing is engineered for demanding industrial conditions where high radial and axial loads, stability and durability are critical. Its precise dimensions make it suitable for assemblies requiring exact tolerances and tight fits.

The bearing’s tapered roller configuration enables it to support combined loads effectively, distributing stress evenly across rollers and raceways. This feature is especially important in heavy-duty applications like transmissions, axles, gearboxes, heavy machinery, or agricultural and construction equipment — anywhere where both radial and thrust loads occur simultaneously.

Thanks to its hardened steel components and robust manufacturing, the bearing withstands repeated cycles, vibrations, and shock loads, offering long service life and stable operation. Because it is delivered as a complete bearing unit (inner cone + outer cup), installation is efficient and straightforward: no need to source separate parts or worry about compatibility. That makes it ideal for maintenance, retrofit or new-build projects.

Whether used in a drive axle, gearbox housing, mechanical transmission, or any construction requiring a tapered roller bearing, HM 88542/10 delivers reliable performance, rigidity, and longevity. For industrial operators, maintenance teams, OEMs or repair shops, this bearing represents an excellent combination of strength, precision and ease of use.

FAQ - Frequently Asked Questions

Q: What types of loads can this bearing handle?
A: HM 88542/10 can handle heavy radial loads as well as substantial axial (thrust) loads in both directions, making it suitable for gearboxes, axles, transmissions or heavy machinery.

Q: Is the bearing delivered as a complete unit, ready to install?
A: Yes — the bearing set includes both the tapered roller (inner) assembly and the matched outer cup, forming a ready-to-mount bearing unit ideal for bearing housings or shafts.

Q: In which applications is this tapered roller bearing most commonly used?
A: Typical applications include drive axles, gearboxes, differentials, heavy-duty conveyors, agricultural and construction machines, industrial transmissions, mechanical drives and other assemblies requiring a robust tapered bearing.

Q: How does the tapered roller design benefit performance under load?
A: The tapered rollers distribute load over a larger contact area, reducing stress, improving stability under combined radial and axial loads, and extending bearing life under heavy use.

Q: Is this bearing suitable for demanding industrial environments?
A: Yes — hardened steel, robust construction, high load capacity and ready-to-install unit make it ideal for harsh industrial conditions, heavy machinery, and applications that demand long life and reliability.
