About SKF YAR 206-2F Ball Bearing Insert, Setscrew
This SKF YAR-2 series chrome steel ball bearing insert with contact and flinger seals is regreasable and locks onto the shaft with two setscrews spaced 120 degrees apart for a three-point contact hold. This lock type minimizes ring distortion and vibration and is suitable for low to moderate speed applications where the shaft rotates in a single or reversing direction. The wide extended inner ring provides increased shaft support and reduced tilting of the inner ring for smooth running. When combined with a matching SKF housing (sold separately), the bearing’s convex sphered outer surface helps compensate for moderate initial misalignment errors. Seals consisting of a pressed sheet steel washer with an acrylonitrile-butadiene rubber (NBR) sealing lip vulcanized to the inner surface (Superagriseal) on both sides of the bearing keep out contaminants, such as dirt and grime, and hold in lubricant applied at manufacture. For improved protection in harsh environments without increased friction, sheet steel flingers, slip fitted to each side of the inner ring, deflect contaminants away from the seals. This single-row ball bearing insert, made of high-grade carbon-chromium steel for durability and resistance to deformity, supports radial and thrust loads. An injection-molded snap-type cage made of glass fiber reinforced polyamide 66 evenly spaces the balls on the raceways for reduced friction, vibration, and noise. Two holes on the outer ring allow for relubrication of the bearing in place. SKF YAR-2 bearings are designed to fit in mounted housing units and are suitable for various industrial applications including mining equipment, fans and blowers, conveyors, and agricultural equipment, among others. Specifications Boundary dimensions and tolerances ISO 9628:1992 Radial internal clearance ISO 9628:1992, CN (normal) Through-hardened steel ISO 683-17 Cage temperature 120 degrees C (maximum) Seal temperature –30 to 100 degrees C (120 degrees C for brief periods) 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.
