SKF BEARINGS can take the heat!

Side impact bars, single moulded body panels and a variable cross-section cowl cross mem- ber are significant safety features in the sturdy H100. One would not easily find a more compact cargo carrier than the H100, with its load space designed for work with a lower deck height of just 775 mm and an unobstructed load area. This makes fast and efficient work of loading and unloading cargo weights of up to 1 000 kg. Latching side walls and a bolting tailgate add extra security and cargo protec- tion. Even with a full load, the H100 is easy to drive and maneuvre thanks to wide-angle outside mirrors that provide a wide rear view Another attribute of the H100 is its high lev- els of interior comfort, with an extra seat and shoulder width for freedom of movement, a driver oriented console and car-like instru- ment cluster that puts the controls at the driv- er’s fingertips. Additional convenience details such as the forward folding centre front seat, sunglasses and cup holders, together with a whole range of well thought out and organised storage places, all combine to provide efficient and functional comfort. When the back of the centre front seat is folded forward, it features two cup holders and a tray between the driver and passenger. Documents, maps, or even light refreshments are easily stored and ready for use in the door mounted storage pockets. An air-conditioner for the cabin is available an option. b

I t is vital for bearings to last and deliv- er reliable quality service irrespective of temperature and application. SKF ex- treme temperature bearings are capable of operating at 350°C without the need for re-lubrication. Extreme temperature bearings are high qual- ity units that deliver numerous cost saving solutions to applications that require optimum bearing performance in hot, dry environments on slow rotating machinery. Grease lubricated bearings often fail at tem- peratures exceeding 250°C because even special greases lose their ability to lubricate adequately above this temperature. In con- trast, the SKF extreme temperature bearing is lubricated by a graphite cage up to 350°C, allowing for the bearings on any equipment to run at its optimum rate. Field experience shows that bearing service life in high temperature applications can be dramatically increased by using graphite lu- bricated extreme temperature bearings. For example, in a cooling bed for sheet metal manufacture, bearing service life was in- creased by a factor of three. In a typical

application such as this, a single bearing of this kind can save up to 4,6 kg of CO 2 e and 1,5 kg of grease per year. A cooling bed equipped with 5000 bearings can save 7,5 tonnes of grease and 23 tons of CO 2 e per year. This is equivalent to an 82% reduction of the climate impact compared to using grease-lubricated deep groove ball bearings. These calculations are based on both bearing and grease savings. The replacement of conventional grease lu- bricated bearings with SKF’s extreme tem- perature bearings will reduce costs across the board. Production does not need to be halted for maintenance purposes to allow for the continuous replacement of lubrication or re-lubrication. As the bearings are able to withstand the temperature extremes they are exposed to, bearing reliability is boosted and bearing service life is improved. This all leads to maximised plant availability and production and ultimately tremendous tome and cost savings for the end user.

The extreme temperature bearing is included in the SKF BeyondZero* portfolio. b
