SKF GW209-PPB4 Harrow Disc Bearing with Seals

The SKF GW209-PPB4 is a specialized agricultural bearing designed specifically for disc harrow applications. This square bore bearing features a W209PPB4 insert with integrated seals to protect against the harsh dirt, dust, and moisture conditions common in farming environments.

Key Features:

• Square bore design with relubricatable construction for extended service life
• Dual seals provide superior protection against contaminants in agricultural applications
• Heavy-duty design engineered to withstand the shock loads and vibration of ground-engaging equipment
• SKF quality manufacturing ensures reliable performance in demanding field conditions
• Direct replacement for OEM harrow disc bearings

This bearing is a critical wear component in disc harrow assemblies, supporting the rotating disc gangs that cut and turn soil. The sealed design helps prevent premature failure from dirt intrusion while the square bore provides positive engagement with the harrow shaft. Regular regreasing through the fitting extends bearing life in abrasive farming conditions.
