210PPB7 Agricultural Ball Bearing 1-5/8" Hex Bore (47.65 x 90 x 30.18 mm) - Replaces Timken / Fafnir W210PPB7, BCA / NTN DS210TT7, Link-Belt W210PPB7, FKL W210PPB7

⚙️ Product Overview
The 210PPB7 / W210PPB7 hex bore ball bearing is engineered to deliver zero-slip torque transmission and maximum contamination protection in severe agricultural environments. Designed with heavy-duty contact rubber seals and a 1-5/8" positive-locking hexagonal bore, it securely locks onto hex shafts without needing keyways or set screws. This minimizes shaft wear, absorbs heavy shock loads, and ensures continuous performance during critical planting and harvesting seasons.
