GW214PP3 Disc Harrow Bearing — Wide Inner Ring, Triple-Lip Sealed, Re-lubricatable
The GW214PP3 is a heavy-duty agricultural disc harrow bearing engineered for the most punishing field conditions. Designed with a wide inner ring and a robust, black-painted thick outer ring, this bearing measures 70 mm (2-3/4″) bore, 125 mm outside diameter, and 39.7 mm in width, making it a direct interchange for leading OEM part numbers used on disc harrows, seeders, rotary tillers, and other tillage equipment.
Advanced Sealing & Lubrication
At the heart of its durability is the triple-lip contact seal system on both sides. These precision-molded rubber seals work together with hardened shield washers to lock out dust, mud, sand, crop residue, and water — the primary causes of premature bearing failure in agricultural applications.
The internal cavity is pre-filled with high-quality, water-resistant lithium complex grease, and the re-lubricatable design (GW series) features an grease groove and hole arrangement that allows periodic regreasing, dramatically extending service life and reducing downtime during critical planting and harvesting seasons.
Heavy-Duty Construction
The extended wide inner ring provides increased shaft support and load distribution, allowing the bearing to handle heavy radial loads and moderate axial loads generated when discs cut through hard, rocky soil.
Chrome steel rings and balls, heat-treated to 58–62 HRC, deliver exceptional wear resistance and fatigue strength, while the stamped steel cage keeps balls precisely spaced for smooth, low-friction rotation.
Installation & Reliability
Installation is fast and reliable: the cylindrical bore slides directly onto the standard shaft, and the spherical outer surface self-aligns within the matching stamped housing or disc mounting hole, compensating for shaft misalignment and frame deflection common in field equipment.
Whether you are rebuilding a disc harrow or supplying aftermarket parts, the GW214PP3 delivers the sealed-for-life convenience, re-greasing flexibility, and rugged construction that keep machines running season after season. Choose it for dependable performance, longer relubrication intervals, and lower total cost of ownership.
