Neutral - 8578/8520CD/C9YA1 | Double Direction Taper Roller Bearing Units | 241.30 × 327.02 × 114.30 mm

Details

Neutral 8578/8520CD/C9YA1 is a double direction taper roller bearing units with inner diameter 241.30 mm, outer diameter 327.02 mm and width 114.30 mm. Additional specifications include bore type CYLINDRICAL, cage STANDARD and lubrication STANDARD.

These bearing is a heavy-duty Double-Row Tapered Roller Bearing (TDO Type). The bearing utilizes a single, continuous double-outer ring (cup) paired with two separate inner rings (cones). The rollers are arranged in a back-to-back configuration. This design expands the effective bearing center, providing extreme rigidity and exceptional resistance to overturning moments (tilting forces). Unlike single-row tapered bearings that can only take thrust in one direction, the dual-cone design enables this bearing to handle massive axial (thrust) loads from both directions simultaneously. Material : High-purity GCr15SiMn high-carbon chromium steel hardened to HRC 58–62. Features are : Optimized Raceway Profile (Logarithmic Profiling), Anti-Rotation Pin Hole, Integrated Lubrication System, Controlled Friction, Thermal Dissipation & Extended Operating Life, Low Noise & Vibration Dampening. Applications : Metal Rolling Mills & Metallurgical Processing, Construction & Material Handling, Mining, Quarrying & Mineral Processing, Marine & Offshore Engineering, Power Generation & Renewable Energy. CD=Counterbored Outer Ring Engineered With Lubrication Holes and Locking Pin Holes On The Outer Diameter, C9=Radial Internal Clearance, YA1=Manufacturer Modification Suffix.
