W211PPB3 RICH 38,89x100x33,3

W211PPB3 RICH Insert Ball Bearing with Square Hole – 39.89 x 100 x 33.3 mm – Triple-Sealed for Extreme Conditions

Built for the harshest environments, the W211PPB3 RICH insert ball bearing delivers outstanding performance and durability where ordinary bearings fail. Engineered specifically for demanding agricultural and industrial applications, it features a unique square bore design that ensures a secure, slip-free fit on square shafts — ideal for high-load, power-transmitting equipment.

With a 39.89 mm square bore, 100 mm outer diameter, and 33.3 mm overall width, this insert bearing is precision-built for tough operational conditions. What truly sets it apart is the advanced triple-lip seal system, shielded by steel plates on both sides. This robust sealing configuration offers exceptional protection from dirt, dust, moisture, and debris — significantly extending the bearing's lifespan even in the dirtiest, most contaminated environments.

While it's specifically designed for low-speed applications due to the reinforced sealing system, the rounded outer ring allows for smooth alignment and easy installation into spherical housings — effectively compensating for initial shaft misalignments. Featuring CN (normal) internal clearance, it ensures stable, vibration-free rotation under standard loads.

Manufactured in China by RICH, the W211PPB3 weighs 1.063 kg and is ideal for agricultural implements, construction machinery, and specialty industrial equipment where maximum reliability and protection are essential.
