6309 2RS CRAFT deep groove ball bearing

CRAFT 6309-2RS Deep Groove Ball Bearing (Heavy-Duty, Sealed)

The 6309-2RS CRAFT is a high-performance single-row deep groove ball bearing, engineered for the most demanding technical arrangements. The 6300 series stands out from other series (6000, 6200) due to its significantly higher dynamic load capacity, allowing safe operation under heavy radial and axial forces. This model features double-sided contact rubber seals (2RS) made of NBR, effectively protecting the precision interior from dust, mud, and moisture. Factory-filled with high-grade lithium grease, it ensures smooth and maintenance-free operation for 45 mm shafts.

Application

• Heavy-Duty Electric Motors: Rotor bearings in power units for industrial applications (e.g., sawmills).
• Agricultural Machinery: Main drive shafts in harvesters, tractors, and balers.
• Heavy Industry: Mechanical gearboxes, crushers, vibrating screens, and high-flow industrial pumps.
• Transport & Logistics: Drive rollers for heavy belt conveyors and axle bearings for specialized vehicles.
• Construction: Concrete mixers, winches, and drive systems for machinery operating in dusty conditions.

Why Choose This Product

The CRAFT 6309-2RS bearing is your guarantee of stability for production lines or field machinery. In 45 mm shaft applications where high pressure occurs, the 6300 series is the best protection against failure. The 2RS sealing ensures that dirt and water have no access to the bearing's core, which combined with factory lubrication, provides peace of mind and saves maintenance time. It is a solid choice for professionals prioritizing proven durability.
