1641-2RS Fractional Inch Deep Groove Ball Bearing

Inch Series Dimensions: Manufactured to precise fractional-inch boundary dimensions for seamless fitment in specific North American and legacy equipment.
Advanced Sealing: Dual nitrile rubber (NBR) contact seals engineered to withstand agricultural dust, moisture, and mild industrial chemicals.
Maintenance-Free: Pre-filled at the factory with a precisely metered volume of high-quality lithium complex grease, requiring no relubrication for the life of the bearing.

Deep Application & Technical Narrative:The 1641-2RS is a highly versatile, fractional-inch deep groove ball bearing utilized extensively across legacy American agricultural equipment, specialized electric motors, lawn and garden machinery, and light industrial conveyor rollers. Because these bearings frequently operate in highly exposed environments—such as dusty fields or wet processing lines—the "2RS" (Two Rubber Seals) designation is critical. These nitrile rubber seals make direct contact with the inner ring, effectively locking in the factory grease while completely locking out abrasive grit and water.
A failed seal means rapid bearing destruction. Inside our workshop, we don't just rely on automated press machines. We manually verify the seating of the rubber seals on the 1641-2RS batches, checking for uniform lip contact and confirming that the bearing rotates smoothly without excessive drag. This careful verification process guarantees a maintenance-free lifespan, delivering excellent value for aftermarket agricultural and motor repair distributors.
Customized B2B Supply & Packaging Solutions:To support diverse wholesale networks, we ensure our full range of bearing types includes critical fractional-inch sizes. The 1641-2RS can be supplied in high-volume, cost-effective bulk industrial packaging or custom-designed, color-branded individual boxes for retail storefronts. We coordinate fast, consolidated air or ocean freight to match your inventory turnaround needs.
Targeted Technical Clarifications (FAQ):

Q: Can I remove the seals if my application requires an oil bath?A: Yes, the rubber seals can be carefully pried out with a specialized tool to convert it into an open bearing for enclosed oil-lubricated gearboxes.
Q: How does a 2RS bearing compare to a ZZ (metal shielded) bearing?A: The 2RS provides vastly superior protection against fine dust and water due to direct rubber contact, whereas ZZ metal shields offer lower friction but are only effective against larger debris.
