Flat seal CF 60 … S10

circularsteelplastic

Non-contact seals series CF are specifically designed for spindle bearings and offer highest efficiency with absolutely leak tightness within a minimized space of 6 mm width only. The labyrinth design is a combination of gaps in axial and radial direction in five steps. The axial gaps are shielding while the radial gaps are providing back transport. A catching groove improves the seal efficiency – even without any shaft rotation. The option of saving sealing air and increased maintenance intervals are offering a considerable commercial progress and advantage. GMN non-contact seals Type CF 60 and CF 619 are produced according to the dimensions of ball bearing rows 60 and 619. They are made of steel, hardened and face-ground. Technical data Material: Steel Hardness: HRC ≥ 45 Plane-parallelism: ≤ 5 μm Range of temperature: -40 °C – 170 °C Speed limit: no limit Series 60 diameter: 20 – 100 mm Series 619 diameter: 40 – 80 mm Width: 6 mm for all sizes Gap seal: CF-Profile Axial clearance: Sax = 1 mm Radial clearance: Srad = 0,5 mm Characteristics: Installation-friendly: No adaptation of the connecting parts required; can be installed directly next to the spindle bearing “sandwiched” between bearing and shaft nut Frictionless: Non-contact design of the inner and outer ring Wear-free: Unlimited service life Unlimited speeds: No axial movement between the spindle bearing and shaft nut Heat-free: No thermal stress for the seal and adjacent components Effective: High sealing effect against heavy spray loads over a large speed range – including when the shaft is at a standstill
