New goods. New services. SKF Group http://10007.us.all.biz Sat, 25 Feb 2012 21:59:25 +0200 http://www.all.biz/img/logo.gif http://10007.us.all.biz http://www.us.all.biz/g177/ SKF produces cylindrical roller bearings in many designs, dimension series and sizes. The majority are single row bearings with a cage. Single and double row full complement bearings (without cage) complete the SKF standard assortment for general engineering. Bearings with a cage can accommodate heavy radial loads and operate at high speeds. Full complement bearings are suitable for very heavy radial loads at moderate speeds. The rollers of SKF cylindrical roller bearings are a key component. Their geometry, the so-called logarithmic profile, provides an optimum stress distribution in the contact zones in the bearing. Their surface finish maximizes lubricant film formation and optimizes rolling motion of the rollers. The benefits derived from this compared with traditional designs include enhanced operational reliability and a greater insensitivity to misalignment.]]> Fri, 29 Dec 2006 00:00:00 +0200 http://www.us.all.biz/g177/ http://www.us.all.biz/g179/ The extensive SKF product range includes a comprehensive selection of bearing housings. This catalogue provides a general view of the SKF range for standard housings and will facilitate the tasks of the designer in selecting the right housings for most common applications.]]> Fri, 29 Dec 2006 00:00:00 +0200 http://www.us.all.biz/g179/ http://www.us.all.biz/g181/ The standard SKF ball bearing units are referred to as Y-bearing units. These units comprise – a Y-bearing (insert bearing) which is a single row deep groove ball bearing with convex sphered outside diameter (fig) – a Y-bearing housing, which has a correspondingly sphered but concave bore (fig). Y-bearing units are ready-to-mount, greased and sealed units which enable initial errors of alignment to be compensated for. They are available as – Y-bearing plummer block units (fig) – Y-bearing flanged units (fig) – Y-bearing take-up units (fig). The housings of the units are produced in a variety of designs and different materials – composite material referred to as Y-TECH – grey cast iron – sheet steel.]]> Fri, 29 Dec 2006 00:00:00 +0200 http://www.us.all.biz/g181/ http://www.us.all.biz/g183/ In addition to ball and roller bearings SKF also produces a comprehensive range of spherical plain bearings and rod ends and has a choice of materials for plain and flanged bushings as well as thrust washers. Spherical plain bearings and rod ends are produced in various designs and with various combinations of sliding contact surfaces. Each design and combination has characteristic properties which make it particularly suitable for certain applications.]]> Fri, 29 Dec 2006 00:00:00 +0200 http://www.us.all.biz/g183/ http://www.us.all.biz/g185/ Radial shaft seals are used between rotating and non-rotating machine components (fig 1). They are made up of – a cylindrical outer covering of sheet steel (shell) or elastomer which seals statically against the housing bore and enables the requisite interference fit of the seal in the housing bore to be obtained as well as facilitating proper installation – the sealing lip of elastomer which provides dynamic and static sealing against the shaft. The lip has a sealing edge which is formed by pressing, cutting or grinding and is normally pressed against the counterface on the shaft with a defined radial force by a garter spring. The edge of the sealing lip and the shaft counterface form the most important functional area of a radial shaft seal. The sealing effect of the lip can be enhanced by providing the contact area of the lip with hydrodynamic aids which may be designed for single direction operation, or for alternating directions of shaft rotation.]]> Fri, 29 Dec 2006 00:00:00 +0200 http://www.us.all.biz/g185/
