The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship

RSR (2RSR) are valid for grease lubrication. Sealing rings/wider inner rings. Sealing rings of series G, GR and SD are matched to the bearing dimensions and can be combined with wider inner rings of series IR. The outer surface of the inner rings can be used as the sliding surface for seal lips. Sealing rings: see “INA
Bearings without an inner ring are the best solution for bearing arrangements where the shaft can be hardened and ground. Needle roller bearings with an inner ring are used if the shaft is not configured as a rolling bearing raceway. Series RNA49..RSR and NA49..RSR are sealed on one side, the designs RNA49..2RSR
Parkour runners need heightened endurance, resilience under stress, and enormous flexibility. These are the qualities that allow them to overcome even the most challenging obstacles – and the same is true of Schaeffler's high-performance rotary bearings and linear products in X-life quality: X-times longer service life,
