Experience robust performance and exceptional durability in your demanding agricultural and industrial applications with the W211PP5 RICH ball bearing with square hole! This specialized bearing is engineered to excel in environments exposed to significant contamination and heavy loads. Its distinctive square bore of 38.89 mm (+0.127/-0.127 mm) is precisely designed for direct, non-rotational mounting onto square shafts, ensuring secure power transmission critical for many types of machinery. The cylindrical outer ring provides a uniform contact surface, making it ideal for straightforward mounting in straight bore housings or for applications where a flat running surface is required. A key feature is the advanced triple-lip seal, reinforced with a metal plate on both sides. This robust sealing configuration offers superior protection against the ingress of severely contaminated media, including dust, dirt, moisture, and agricultural debris, while effectively retaining internal lubricant. This significantly enhances the bearing's longevity and reduces maintenance requirements, even in harsh, low-speed operating conditions. The C3 clearance (greater than normal) allows for improved performance under conditions of high temperature, rapid acceleration, or slight shaft misalignment, making it perfectly suited for demanding applications.

With its precise dimensions of 38.89 mm square bore, 101.6 mm outer diameter, and an inner ring width of 44.45 mm (outer ring width of 36.5 mm), this RICH ball bearing is perfectly suited for agricultural equipment, heavy-duty conveyor systems, and various industrial applications requiring reliable power transmission and superior sealing. It is designed to accommodate a 38.1 mm shaft size, ensuring broad compatibility.

Proudly manufactured by RICH in China, this quality ball bearing is an essential component for critical machinery here in Europe and across global industrial sectors.

Key Performance Advantages:
