Frequently Asked Questions

Q: What makes the triple seal in W208PP8 better than standard seals?

The triple seal provides three layers of defense against contaminants, ensuring that grit and water cannot reach the rolling elements, which dramatically extends the bearing's life in dirty agricultural environments.

Q: Is the square bore compatible with all disc harrow brands?

The W208PP8 follows standard industry dimensions (28.6mm ID), making it compatible with most major agricultural equipment manufacturers that utilize square bore configurations.

Q: How do I maintain these bearings for maximum longevity?

While the triple seal reduces maintenance, we recommend regular visual inspections and using a high-quality EP grease during scheduled maintenance intervals to ensure optimal lubrication.

Q: What is the difference between Cr and Cor ratings?

Cr (36.8KN) refers to the Dynamic Load Rating, which is the load a bearing can handle while rotating. Cor (19.9KN) is the Static Load Rating, representing the maximum load the bearing can withstand without permanent deformation while stationary.

Q: Can this bearing handle high-impact loads in rocky soil?

Yes, the W208PP8 is specifically designed for the high-impact nature of tillage. Its robust internal geometry is optimized to distribute shocks and prevent premature race failure.

Q: Do you offer bulk pricing for agricultural distributors?

Yes, we provide competitive tiered pricing for wholesale distributors and large-scale farming enterprises to ensure the best cost-per-unit for fleet maintenance.
