67885/67880D Double Row Tapered Roller Bearing
- Bi-Directional Thrust Capacity: The double-row design allows the bearing to absorb heavy axial loads in both directions simultaneously.
- Enhanced Radial Rigidity: Provides maximum shaft support to prevent deflection in heavy-duty machinery.
- Pre-Set Internal Clearance: Double cup assemblies are factory-matched with spacers to ensure accurate internal clearance upon installation.
- Deep Case Hardening: Resists raceway spalling and sudden shock impacts in harsh industrial environments.

Product Introduction
The 67885/67880D is a heavy-duty, double-row tapered roller bearing engineered to handle massive radial loads and bi-directional thrust loads. With impressive dimensions of 190.5 x 266.7 x 93.67 mm, this bearing assembly features a double cup (denoted by the "D" suffix) and two single cones. Manufactured from vacuum-degassed GCr15 chromium steel, it offers exceptional structural rigidity and fatigue resistance. This robust design makes it an essential component for B2B industrial clients operating in heavy machinery, steel rolling mills, and mining equipment, where equipment reliability and extended uptime are critical.
Applications
Steel rolling mills and metallurgical equipment.
Heavy mining haul trucks and crushing machinery.
Large-scale industrial gearboxes and rotary equipment.
FAQ
Q: What does the "D" suffix signify in 67885/67880D?
A: The "D" suffix indicates a double cup. This means the bearing assembly consists of one double outer ring (cup) and two single inner rings (cones).
Q: Are these bearings suitable for high-speed applications?
A: Double row tapered roller bearings are primarily designed for extreme load capacities at low to moderate speeds, typical in heavy industry.
