Pre-lubricated, the company's sealed linear ball bearings can save the time and costs of the bearing lubrication process, which can be significant in high-volume applications. Users can also realize environmental benefits by avoiding the non-green conditions associated with grease application. The linear ball bearings are available in both compact and standard metric versions, all of which come with integral double-lip seals to retain the lubricant and protect against contamination. Seals consist of an inner lip that prevents lubricant from escaping within the bearing and an external lip that wipes the shaft surface as the bearing moves. The components employ plastic cages with hardened steel raceway segments that guide the ball sets. Their re-circulating balls reduce friction and provide unlimited stroke. Shaft diameters range from 3 mm to 80 mm and basic dynamic load ratings range from 60N to 37,500N, depending on size and type. Additionally, special greases are available for application-specific requirements. SKF LINEAR MOTION & PRECISION TECHNOLOGIES, Bethlehem, PA. (800) 541-3624.
