Key Performance Features

01. Superior Contamination Exclusion

The dual NBR rubber contact seals create an effective barrier against water ingress, dust penetration, and abrasive particles. This sealing configuration significantly extends bearing service life in outdoor, agricultural, and washdown environments where contamination is unavoidable.

02. Reliable Performance in Wet Conditions

Unlike open or metal-shielded bearings, the 6018-2RS rubber seals provide effective protection against moisture and water spray, making it ideal for outdoor equipment, agricultural machinery, and food processing applications requiring periodic washdown cleaning.

03. Enhanced Operational Safety

The contact seal design prevents grease leakage and contaminant entry, ensuring consistent lubrication film thickness and reducing the risk of unexpected bearing failure. This reliability is crucial for safety-critical applications in construction, agriculture, and material handling.

Design & Configuration

The 6018-2RS features two NBR rubber contact seals providing optimal protection for most industrial and outdoor applications. The contact seal design creates slight friction, resulting in lower maximum speeds compared to open or metal-shielded variants, but delivers superior sealing performance. For applications requiring higher speeds in clean environments, consider the 6018-ZZ (metal shielded) version. For extremely contaminated environments with frequent washdown, the 6018-2RS provides the best protection-to-performance ratio.

"The preferred sealing solution for agricultural equipment, construction machinery, and outdoor industrial applications where environmental protection, maintenance-free operation, and long-term reliability are paramount concerns."
