⚙️Product Description:
Operating heavy industrial equipment where massive shock loads, structural frame flex, and angular shaft misalignment threaten conventional bearings? The 22318CC/W33 Spherical Roller Bearing (90x190x64mm) is engineered to thrive under extreme mechanical punishment. Featuring a 90mm bore, 190mm outer diameter, and a massive 64mm width, this double-row bearing incorporates barrel-shaped rollers that automatically compensate for shaft deflection up to 2 degrees. The optimized “CC” architecture utilizes two stamped window-type steel cages and a flangeless inner ring for lower friction and maximized dynamic load ratings, while the W33 specification integrates a circumferential lubrication groove and three oil holes on the outer ring for effortless re-greasing. It is the industrial backbone for jaw crushers, vibrating screens, rolling mills, and heavy mining conveyors. As a premier global B2B bearing trader, we empower your heavy machinery fleet: lower your operational replacement costs with our field-proven RMO proprietary brand, or contract us to source tier-1 international legacy brands (such as SKF, FAG, or NSK equivalents) for critical OEM builds.
⚙️Product Features:
- Self-Aligning & Deflection Tolerance: Symmetrical double-row spherical rollers compensate for severe mounting errors or dynamic shaft deflection under heavy shock loads without causing friction spikes or localized stresses.
- Optimized CC Design & Steel Cages: The “CC” designation signifies a flangeless inner ring and floating guide ring centered on the inner ring, combined with two stamped steel cages for exceptional roller guidance and high dynamic load capacity (~610 kN).
- W33 Re-Lubrication System: Features a outer ring annular groove paired with three lubricant feed holes, ensuring rapid oil/grease distribution straight to the raceways for continuous cooling and contamination flushing.
- Heavy Metallurgy Forging: Machined from high-purity GCr15 / 100Cr6 chrome steel subjected to multi-stage heat treatments, granting extreme toughness against raceway fatigue and heavy impact loads.
- Dual-Track B2B Supply Capability: We bridge your procurement options seamlessly. Wholesale bulk volume shipments of high-performance RMO stock for mining overhauls, or task our sourcing table to acquire fully traceable international brands for heavy machinery manufacturing.
⚙️Product Applications:
Engineered specifically for the toughest heavy-duty environments where shock loads and misalignment are daily occurrences, the 22318 series is mandatory for:
- Mining equipment: Jaw crushers, cone crushers, ball mills, and heavy vibrating screens.
- Metallurgy and steel plants: Rolling mill gearboxes, continuous casting roller tables, and heavy processing drives.
- Heavy material handling: Incline mining conveyor pulleys, bucket wheel excavators, and port crane hoists.
- Heavy construction & cement: Rotary kilns, clinker grinders, and heavy concrete mixing plants.
- Global mining service suppliers, heavy equipment overhaul facilities, and B2B industrial drive component importers.
⚙️Precautions:
| 1. Keep clean | 2. Use with caution | 3. appropriate tool | 4. Hot-loading | 5. Be careful of rust |
| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
