SKF 61828 bearing
Product description
The SKF single-row, double-sealed radial bearing has symmetric races to support radial loads while maintaining high speeds and rotational accuracy. It conforms to the precision standard Annular Bearing Engineers Committee (ABEC) 1 for performance within a narrow range of variation, and its deep grooves make it capable of supporting heavier loads than standard grooves and keeping balls stable for high speeds. It has a CN (normal) radial internal clearance for applications that do not involve thermal expansion, and its steel cage evenly spaces the rollers for even load distribution and prevents contact to reduce friction, vibrations, and noise. It has rubber seals on both sides of the bearing to keep lubricant in and contaminants out. This radial ball bearing is suitable for use in general purpose applications that primarily involve radial loads and minimal axial loads at relatively high rotational speeds. These include transmissions, motors, and pumps, among others.SpecificationsMain bearing dimensionsISO 104:2002Basic dynamic load ratingsDIN ISO 281Dimensional and geometric tolerancesISO 199:1997, tolerance class PNThrough-hardening steel for inner and outer rings and rollersISO 683-17Pressed sheet steel for cage(DIN) EN 10111:1998Load carrying capacity and lifeISO 281:1990System for creating part numbers for rolling bearingsDIN 623-1Rolling 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 Group manufactures bearings and units, seals, mechatronics, and lubrication systems that meet International Organization for Standardization (ISO) 14001 and 9001, and Occupational Health and Safety Assessment Series (OHSAS) 18001 standards for quality assurance. The company, founded in 1907, is headquartered in Göteborg, Sweden.

Open Deep Groove Ball Bearings: One of the most commonly used bearings, the open types are manufactured without seals to allow for the free circulation of either oil or grease, used in gearboxes and other environments where no foreign matter would be present and a lubricant supply is available.
Benefits: Used widely in transmissions etc, can be used in oil or greased, cost effective solution
61828-2RS1 SKF Sealed Deep Groove Ball Bearing 140x175x18mm
Deep Groove Metric Ball Bearings are very versatile. Very simple in design being non-separable these bearings are suitable for high and even very high speeds, robust in operation and require little maintenance. Having deep raceway grooves in close proximity to the balls enables a deep groove ball bearing to accommodate axial loads in both directions as well as radial loads, even at high speeds. Single row deep groove ball bearings are the most common and widely used bearing.
