The 6017-2RS is a robust Double Rubber-Sealed Deep Groove Ball Bearing designed for medium to heavy-duty industrial applications requiring superior contamination protection. Fitted with two high-quality rubber contact seals (2RS) on both sides, it provides excellent defense against dust, moisture, and debris while retaining lubrication for extended service life. With an 85 mm bore, 130 mm outer diameter, and 22 mm width, this bearing delivers reliable performance in electric motors, gearboxes, and industrial equipment where operational dependability and environmental sealing are critical.

The 6017-ZZ is a Double Metal-Shielded Deep Groove Ball Bearing designed for medium to heavy-duty industrial applications requiring reliable performance with minimal maintenance. Fitted with two pressed steel shields (ZZ) on both sides, it effectively retains lubrication while permitting higher operational speeds compared to contact-sealed variants. With an 85 mm bore and standard 22 mm width, this bearing delivers robust performance for electric motors, gearboxes, and industrial equipment where contamination resistance and speed capability are critical.

The 6018 is an Open-Type Deep Groove Ball Bearing engineered for applications requiring maximum flexibility in lubrication and sealing arrangements. Without integrated seals or shields, this bearing design allows for customized grease selection, relubrication intervals, and external sealing solutions tailored to specific operating conditions. Featuring a 90 mm bore and 24 mm width, the 6018 open configuration is ideal for large electric motors, industrial gearboxes, and heavy machinery where maintenance accessibility and optimized lubrication management are priorities.

The 6018-2RS is a Double Rubber-Sealed Deep Groove Ball Bearing specifically engineered for demanding operating conditions where superior contamination exclusion and moisture resistance are essential. Equipped with two NBR rubber contact seals (2RS) on both sides, this bearing provides exceptional protection against dust, water spray, and fine particulate matter while retaining high-quality grease lubrication throughout extended service intervals. With a 90 mm bore diameter and 24 mm width, the 6018-2RS delivers reliable performance for agricultural machinery, outdoor equipment, and industrial applications exposed to challenging environmental conditions.

Compact yet highly durable, the S6001-2RS is a single-row deep groove ball bearing purpose-built for demanding, moisture-rich settings. Unlike standard carbon or chrome steel variants, this model is forged from premium stainless steel, granting it exceptional immunity to oxidation, corrosive chemicals, and regular water exposure. Featuring precision dimensions of a 12mm bore, 28mm outer diameter, and 8mm width, this lightweight bearing utilizes twin Nitrile Butadiene Rubber (NBR) seals to trap lubrication and block abrasive particles, making it an essential component for sanitary and outdoor mechanical systems.

The 6005-2RS is a versatile, light-series single-row radial ball bearing engineered to deliver smooth rotational performance where installation space is limited but reliable operation is essential. Differing from open configurations, this model incorporates dual contact synthetic rubber seals (2RS) that provide an exceptional defensive barrier against dust, moisture, and fine grit while securely locking in the factory grease. Standardized to metric dimensions—featuring a 25 mm bore, 47 mm outer diameter, and 12 mm width—the 6005-2RS offers the ultimate mechanical solution for mid-sized electric motors, power tools, and high-efficiency automotive components.

The 6004-2RS is a high-grade, single-row radial ball bearing designed to supply dependable operational stability and efficient friction reduction across medium-duty setups. Distinct from open configuration components, this unit utilizes dual-sided synthetic rubber contact closures (2RS) to forge an impenetrable physical boundary against ambient moisture, particulate matter, and fine debris while securely sealing the internal lubricant. Complying with standard metric scaling—featuring a 20 mm bore diameter, 42 mm outer diameter, and 12 mm width—the 6004-2RS stands as a versatile mechanical assembly for compact power tools, light vehicle hubs, and household appliances.
