916642/916610 Heavy Tapered Roller Bearing 69.987x176.213x54.77mm

Extreme Load Capacity: The highly disproportional OD-to-ID ratio allows for massive rolling elements, providing unmatched radial load support.
Shock Load Resistance: Thick-walled outer cup and heavy-duty cone resist deformation during severe operational impacts.
Precision Alignment: Tapered geometry naturally manages bi-directional forces when mounted in opposed pairs, maintaining rigid shaft centering.
Extended Fatigue Life: Deep heat treatment ensures the raceways can withstand continuous heavy-tonnage stress without surface failure.

Product Introduction

The 916642/916610 is a severe-duty, large-profile imperial tapered roller bearing characterized by its extremely thick cross-section, designed for massive load environments. With a bore of 69.987 mm and an oversized outer diameter of 176.213 mm, this set (Cone: 916642, Cup: 916610) provides an unusually high dynamic load rating relative to its shaft size. Built from premium vacuum-degassed GCr15 steel, this bearing is engineered to absorb extreme shock loads and massive radial pressures found in mining equipment, heavy commercial axles, and heavy-duty industrial pressing machinery.

Product Features

Applications

Mining haul truck final drives and heavy off-highway axles.
Industrial crushers, heavy stamping presses, and metallurgical equipment.
Large-scale gearboxes in the oil and gas industry.

FAQ

Q: Why is the outer diameter so large compared to the inner bore?
A: This specific heavy-series geometry is designed to accommodate extremely large, high-capacity rollers for applications where shaft size is limited but structural loads are massive.
Q: Do you provide material test certificates for this heavy bearing?
A: Yes, full Certificates of Analysis (COA) for the steel and precision test reports can be supplied for B2B procurement.
