SKF 4204 ATN9 Double Row Ball Bearing, Deep Groove Design, ABEC 1 Precision, Open, Plastic Cage, Normal Clearance, 20mm Bore, 47mm OD, 18mm Width, 13000 rpm Maximum Rotational Speed, 2813.0 pounds Static Load Capacity, 4005.00 pounds Dynamic Load Capacity

This SKF 4200 series double-row deep groove ball bearing is an open bearing, and has a reinforced polyamide cage and normal clearance rating. It is suitable for applications that support high speeds, radial loads, and thrust loads in both directions. The 4200 series has a smaller cross-section than the 4300 series, making it suitable for smaller spaces, lighter loads, and higher speeds. Because it has two rows of rolling elements, this bearing provides a higher load carrying capacity than a single-row ball bearing. This bearing is made of low-alloy, through-hardened carbon chromium steel for durability and resistance to deformity under heavy loads, and has deep inner and outer races that conform to the balls that run in them, allowing higher speeds and creating lower friction than comparable-sized roller bearings. 0 Its open design facilitates lubricating the bearing in place and dissipating heat. This bearing has an injection molded snap-type cage made of polyamide 66 to prevent the balls from coming into contact with each other during use, reducing friction, vibration, and noise. This cage type can be used at operating temperatures up to 120 degrees C (250 degrees F). The bearing has a normal radial internal clearance designation, making it suitable for applications where the load and speeds do not result in thermal expansion. This clearance provides latitude for self-realignment and compensates for static and dynamic alignment errors. Additionally, the bearing is manufactured to normal tolerances in accordance with International Organization for Standardization (ISO) 492:2002 specifications. This deep-groove ball bearing is for use in commercial and industrial applications including generators, pumps, original equipment or replacement parts in motors, office automation, farm equipment, and conveyor rollers.Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. 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 rudder shafts, and aggregate crushers, among others.SKF manufactures bearings, seals, and lubrication systems for automotive, OEM, energy, and other and industrial applications. The company, founded in 1907, is headquartered in Gothenburg, Sweden, and meets International Organization for Standardization (ISO) TS 16949 and 9001 standards for quality assurance.
