rA,
A NEW type of bearing material has
been introduced by Glacier Metal Co. Ltd. which, it is said, fills the gap between non-lubricated bearings (such as the DU made by the concern) and fully lubricated bearings. The name given to the material is DX and it need be lubricated on assembly only for applications where further lubrication is difficult or impossible.
Glacier DX is a tripartite material with the mating surface an acetal resin polymer which is interlocked with a steel backing through the medium of porous bronze. The acetal resin surface is said to have the desirable property of retaining a small amount of oil in an unbroken surface film for a longer period than any other metal or resin so far evolved. An advantage of DX over DU is that it can be machined before or after installation. DX is available as strip, bushes, hemispherical cups and thrust washers and is usually supplied with surface indentations which form grease cups.
Lacre Expansion : A factory development programme designed to double production capacity within the next two years has just been completed by Lacre Ltd„ the municipal vehicle specialists. Lacre, who manufacture road and airport-runway suction sweeping equipment on Bedford chassis, have added 15,000 sq. ft. of floor space to the factory area in Hatfield Road, St. Albans, and 2,400 sq. ft. to the administrative block— increasing the total floor area of the premises to 44.800 sq. ft.
