Specification: Model: HK0408 Drawn Cup Material: ST14 Steel Cage Material: ST13 Steel Needle Roller Material: Chromium Steel (GCr15) Bore Diameter (Fw): 4mm Outside Diameter (D): 8mm Width: 8mm Static Load Capacity (Cor): 1070N Dynamic Load Capacity (Cr): 1540N Maximum Rotational Speed (Oil): 40000rpm Number of Packs: 10 PcsDescription: Drawn Cup Needle Roller Bearing features a deep drawn, thin-walled outer ring. They are compact bearings with high load carrying capacity and stiffness. These bearings are especially suitable for high dynamic loads or radial-limited installation. They are mounted with a tight interference fit in the housing. Shoulders or snap rings are not required to locate the bearing axially, thus enables a simple and economic design of the housing bore. For various applications such as planetary gears in automobiles, constant mesh gearboxes, agricultural and construction equipment, pumps and compressors, and two-cycle engines, among others. NOTE: Install with a press machine or special tools instead of hammers because beating may lead to local deformation or brittle fracture.
