Feature:1. This oneway bearing can rotate freely in one direction and lock in the other direction.2. Made of GCr15 bearing steel, the hardness is HRC6165after heat treatment, compact size, high load capacity.3. With enough space for storing grease, it has a longer lubrication interval, more dependable to use.4. It can completely "lock up" the drive shaft when it receives driving force, avoiding the problem of insufficient "locking up" performance of traditional stamped outer ring oneway bearings.5. Widely used in textile machinery, printing machinery, automotive industry, household appliances, currency detectors, etc.Specification:Item Type: One-Way Bearing Material: GCr15 Bearing SteelModel: CSK20PPInner Diameter: Approx. 20mm/0.8inOuter Diameter: Approx. 47mm/1.9inThickness: Approx. 14mm/0.6in.Package List:1 x One-Way Bearing
