SKF 6021-2RS Deep Groove Ball Bearing | Sealed (105x160x26 mm) | Industrial Grade

The SKF 6021-2RS is a robust single-row deep groove ball bearing engineered for high performance and reliability across demanding industrial applications. Featuring a 105 mm bore, 160 mm outer diameter, and 26 mm width, this bearing offers an optimal balance between load carrying capacity (Dynamic Cr: ~85 kN) and limiting speed. The deep raceway grooves and close conformity between the raceways and balls enable the bearing to handle not only radial loads but also moderate axial loads in both directions. The designation '2RS' signifies the inclusion of two contact rubber seals, providing superior protection against contaminants, dust, and moisture while ensuring optimal retention of the high-quality internal lubrication, leading to minimized maintenance requirements and extended operational life. As a premium product from SKF, the 6021-2RS guarantees exceptional manufacturing quality, minimizing friction, heat generation, and noise, even under continuous operation. This bearing is the standard choice for mission-critical components such as industrial pumps, large electric motors, high-speed gearboxes, and HVAC systems where reliability is non-negotiable. Its sealed design makes it a cost-effective choice by eliminating the need for external grease replenishment, significantly reducing total cost of ownership and maximizing equipment uptime in challenging environments.
