Flat seal CF … A0

circularaluminumshielding

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. For effective sealing of standard deep groove ball bearings, GMN labyrinth seals in the design CF … A0 are produced from aluminum with unground flat surfaces in the dimensions of bearing series 62. Technical data: Material: Aluminum Temperature range: -40 °C – 200 °C Design: Main dimensions (shaft/hub) identical to roller bearings series 62 Shaft diameter: 10 – 50 mm Width: constant 6 mm Gap seal : CF profile Axial play: Sax = 1 mm (entire axial movement) Radial play: Srad = 0.5 mm (entire radial movement) Connecting parts: Shaft k5 / hub J6 Characteristics: Insensitive to temperature: For operating temperatures up to 200 °C Suitable for high speeds: Low mass of the inner ring with rotating shaft Frictionless: Non-contact design of the inner and outer ring Wear-free: Unlimited service life Abrasion-free: Fulfills the highest cleanliness requirements Heat-free: No thermal stress for the seal and adjacent components
