Sealed unit plummer blocks
fore coating and the lubricant displaces moisture and leaves a low-friction lubricating film which is claimed to be hard dry after three hours. ACDL can be used for small assemblies such as plain bearings, slides, gears, pumps, shafts, and pins. It has proved particularly successful for the lubrication of Swarf conveyors. ACDL is soluble in oil or hydrocarbon solvents but impervious to steam, water or alkalis. Guardian Industrial OPT, Kent, England

WHEEL
A self-propelled (Fig 4) for all types of off-highway vehicles was recently announced by the Borg-Warner Corporation The wheel is driven by a hydraulic power unit and gear reduction assembly. It does not require a conventional axle, clutch or transmission system and can provide infinitely variable forward and reverse speeds without gear and changing. The wheel is powered by a remote axial pump which supplies hydraulic oil via hose lines. The wheel can also be driven by mechanical or electrical power inputs.
SEALED
UNIT PLUMMER
BLOCKS
Claimed to incorporate into the one unit advantages only obtainable otherwise in two or three units, the new type of plummer block (Fig 5) from the FAG Bearing Company is a corn-’ pact, fully self-aligning, re-greasable self-contained unit. With a choice of standard ball or roller bearings and composition or double-lipped synthetic rubber seals, a range of shaft sizes from 3,‘4-2in (20-50mm) in diameter are available. Radial carrying capacities vary from 20201bf (900 kgf) on a shin shaft running at 12rev/min to 31501bf (1450 kgf) ,for a 2 in shaft working at 1500rev/min. Grease space in the units has been designed to suit any requirements, permitting the units to be re-greased whenever necessary. Typical applications include fan runners, bottle washing plants and saw benders. FAG Bearing Co Ltd, Heath Mill, Road, Wombourne, hampton, England

An advantage of the hydraulic wheel is that wheels do not have have to be mounted in line, each can be mounted on its own spindle and driven independently of the others. This gives the designer freedom to develop a vehicle to a particular job or type of terrain. Typical applications are for articulated vehicles, agricultural combines, road rollers and harvesters. Two models are currently available. Model 8 gives 90 OOOlbf. in torque at peak loads and a 30.89 to 1 reduction ratio. Model 10 gives 1’750001bf. in torque at peak loads and a 36.82 to 1 reduction ratio. Carl Byoir & Associates, Berkeley Square House, London 5
SECONDAtiALTRIBOLOGYCOMMITTEEREPORT
Mintech’s Committee on Tribology have now published their second annual report. The report says that significant progress was made during 1968 on developments in the field of tribology. Three centres of tribology (at the Universities of Leeds and Swansea and at the UKAEA Laboratories. Risley). operating on a commercial basis, were set up as part of a- . national framework to offer consultancy services to industry for solving tribological problems. The number of orders already placed by industry with these centres indicates that a real need is being met. Interest in tribology widened considerably during the year and the report shows that nearly 1,000 engineers, industrialists, teachers and students attended courses ranging from evening courses to full time university MSc studies. Efforts were continued during 1968 to relate tribology research to actual industrial needs. The report points out that the greatest benefits should arise from the industrial application of existing results of research and savings arising from apparently trivial refinements in design and practice can often be substantial. Publicising the value of, and the facilities for, good tribological design and practices was found to be one of the most important problems of tribology and publicity activities were stepped up during the year. The report stresses that there is still a gap between education in tribology matters and the needs of industry for trained TRIBOLOGY
