⚙️Product Description:
The RAE15-NPP-B (also designated as YET203-15CW) is a radial insert ball bearing custom-built with a spherical outer ring and an eccentric locking collar. Designed with a 15 mm shaft bore diameter, 40 mm outer ring diameter, 12 mm outer ring width, and 28.6 mm total inner ring width with collar, this insert bearing seamlessly compensates for initial mounting misalignment when fitted into compatible pillow blocks or flange housings. Featuring dual P-type rubber seals (NPP) and a extended inner ring side, it ensures tight shaft locking under single-direction rotation while sealing out moisture and dirt. As a foreign trade supply specialist, we maintain direct inventory of our proprietary RMO brand while offering procurement solutions for top global bearing brands.

⚙️Product Features:
- Eccentric Locking Collar Mechanism: Provides quick, high-clamping shaft attachment optimized for single-direction shaft rotation without scoring the shaft surface.
- Spherical Outer Ring Profile: Profiled outer diameter self-aligns effortlessly within matching cast iron or pressed steel housings to accommodate shaft deflection.
- Dual P-Type Contact Seals (NPP): Reinforced rubber lip seals on both sides maintain factory grease retention while providing superior defense against fine dust and washdown water.
- Extended Inner Ring Design: Extended inner ring width (28.6mm) provides stable shaft seating, reducing vibration drag and dynamic tilt under dynamic radial loads.
- Dual-Track Global Supply Options: Immediate warehouse availability of our cost-effective RMO brand alongside flexible sourcing for top tier international brands.
⚙️Product Application:
- Agricultural Equipment Drives: Seeding machinery, grain cleaning rollers, rotary harvesters, and baler shaft positioning.
- Light-Duty Material Handling: Small conveyor belt idler rollers, sorting line drive shafts, and packaging machinery transfers.
- Textile and Printing Machinery: Fabric tension rollers, printing press guide shafts, and automated yarn processing modules.
- HVAC and Fan Drive Systems: Commercial air handler shafts, ventilation fan blowers, and quiet HVAC drive units.
⚙️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. |
