CR 55179 Tapered Roller Bearing – 55x90x23mm High Capacity Industrial Gearbox Unit
The CR 55179 is a high-precision Single Row Tapered Roller Bearing (TRB) engineered for critical industrial applications demanding exceptional axial and radial load management. Constructed from high-carbon chromium steel (SAE 52100 equivalent) and featuring a precision-machined inner ring, outer ring, and steel cage assembly, this robust bearing is designed to maintain geometric accuracy under significant mechanical stress, misalignment, and moderate vibration. Its optimized roller profile ensures superior stress distribution, effectively minimizing edge loading and maximizing the predicted mean time between failures (MTBF) under dynamic conditions. This unit is manufactured to stringent ISO dimensional tolerances, guaranteeing optimal fit and performance reliability.
Ideal for use in heavy-duty commercial vehicle axles, large gear reduction units, rolling mill equipment, and high-load agricultural machinery, the 55179 delivers unparalleled operational stability and energy efficiency. Choosing the CR 55179 ensures reduced operational downtime and lower maintenance costs due to its inherent robust design and the CR brand's commitment to quality control. Its configuration is specifically optimized for applications where a separable design allows for easier mounting and precise clearance adjustments during installation and maintenance cycles.
