A sliding contact surface-forming material with improved friction-proof and wear-proof characteristics under dry friction conditions such as in the open air, while keeping the low swelling, friction-proof, and wear-proof characteristics under moist atmosphere typically under water unchanged, wherein the sliding contact surface-forming material includes a reinforcing base impregnated with a resol-type phenolic resin having polytetrafluoroethylene resin dispersed therein, the reinforcing base being composed of a woven fabric formed by using, respectively as the warp and the weft, a ply yarn which is formed by paralleling at least two strands of a single twist yarn spun from fluorine-containing resin fiber and a single twist yarn spun from polyphenylene sulfide fiber, and by twisting them in the direction opposite to the direction in which the single twist yarns were spun.

Sliding contact surface-forming material, slide bearing containing same, and method of using same in a moist environment

A sliding contact surface-forming material, and method of making the material are disclosed, the material having minimal swelling and excellent friction-proof and wear-proof characteristics when used in moist environments such as in water, and improved in the friction-proof and wear-proof characteristics under dry friction conditions such as in the open air, particularly under oscillation conditions for testing journal. The material includes a reinforcing base impregnated with a resol-type phenolic resin having polytetrafluoroethylene resin dispersed therein. The reinforcing base is composed of a woven fabric formed by using, as each of the warp and the weft, a ply yarn which is formed by paralleling at least two strands of a single twist yarn spun from fluorine-containing resin fiber and a single twist yarn spun from polyester fiber, and by twisting them in the direction opposite to the direction in which the single twist yarns were spun.

A high-strength brass alloy for sliding members, consists of, by mass %, 17 to 28% of Zn, 5 to 10% of Al, 4 to 10% of Mn, 1 to 5% of Fe, 0.1 to 3% of Ni, 0.5 to 3% of Si, and the balance of Cu and inevitable impurities. The high-strength brass alloy has a structure that includes a matrix of a single phase structure of the &#x3b2; phase and includes at least one of Fe&#x2014;Mn&#x2014;Si intermetallic compounds in the form of aciculae, spheres, or petals dispersed in the &#x3b2; phase.

A mast assembly for a forklift truck includes a plurality of guide units. At least one of the guide units includes a sliding pad member made of a plastic material and having a block-shaped body, which is hollow, is open at its base side, and has a rectangular ring-shaped cross section. The sliding pad member has a rectangular, plain, front wall provided at the side of the block-shaped body opposite to the base side thereof. The front wall has a sliding contact surface. Reinforcement ribs are formed on the inner surface of the front wall. Grooves are formed in the sliding contact surface, extending along the respective ones of the reinforcement ribs and helping avoid formation of shrinkage depressions in the sliding contact surface. The block-shaped body includes first and second pairs of opposing side walls. Tabs are formed on the first pair of opposing side walls.
