⚙️Product Description:

The 23940CC/W33 (200 x 280 x 60 mm) is an extra-light thin-section spherical roller bearing engineered for heavy industrial applications requiring high radial load capacity within an extremely compact outer diameter profile. Featuring a 200mm bore diameter, 280mm outer diameter, and 60mm width, this self-aligning bearing integrates two symmetrical rows of barrel rollers running in a spherical outer ring raceway, complemented by two stamped steel cages (CC design) and an oil groove with lubrication holes (W33). Designed to automatically compensate for shaft deflection and mounting angular misalignment, it delivers exceptional operational reliability under heavy dynamic loads where installation space is severely restricted. We maintain stable warehouse stock of our proprietary RMO brand alongside swift global sourcing for leading international bearing brands, serving manufacturers of heavy reduction gearboxes, paper mill dryers, mining conveyors, and metal processing equipment.

⚙️Product Features:

Ultra-Thin Cross-Section Profile: 239 Series thin-wall geometry optimizes outer diameter envelope, maximizing internal shaft rigidity and space economy in large-bore machinery.
CC Design Stamped Steel Cages: Guided inner ring design with two independent steel window-type cages minimizes friction and heat buildup during continuous rotation.
Automatic Angular Misalignment Correction: Spherical outer raceway effortlessly absorbs frame twisting and shaft flex under heavy dynamic bending moments.
Efficient W33 Lubrication Feature: Outer ring lubrication groove and re-lubrication holes guarantee even oil/grease delivery directly to rolling elements.
Comprehensive Sourcing Support: Direct supply from RMO factory inventory combined with efficient global procurement channels for premier international bearing brands.

⚙️Product Application:

Mining & Material Handling: Heavy-duty belt conveyor drive drums, bucket wheel excavator countershafts, and vibrating screen exciters.
Pulp & Paper Manufacturing: Paper machine dryer cylinders, wire section guide rolls, and calender stack drive units.
Metallurgy & Steel Mills: Continuous casting machine segment rollers, cold rolling mill pinch rolls, and coil handling crane drives.
Heavy Power Transmission: Industrial planetary gearboxes, wind turbine yaw drives, and marine winch drum supports.

⚙️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.
