A bicycle chain lubricant that may be applied as a coating on a bicycle chain is a crystalline solid at ambient temperatures, yet when the chain is in motion the forces around internal components locally transforms the coating to a lubricous fluid. This increases chain efficiency in the drive train and reduces ware by limiting water and dirt access to chain internal components.

To provide an end portion sealing member for a linear motion mechanism having good lubrication characteristics and a high degree of protection against dust. An end portion seal member capable of being attached at either end of slider in linear motion mechanism comprising rail and slider, wherein said end portion seal member has support frame body arranged at an outside circumference of said rail; base fabric portion, the back surface of which is secured to an inside circumferential surface of said support frame body; and cut pile that protrudes from a front surface of said base fabric portion; wherein fiber tip portions of said cut pile are bent and made to abut the rail in such fashion as to occlude a gap between said rail and said support frame body; and lubricant has been made to be retained in advance in spaces between pile fibers of said cut pile.

A lubricant includes at least 45 wt % paraffin oil, less than 8 wt % of a pyrophosphate or triphosphate, more than 6 wt % of a group 6 disulfide or diselenide and up to 27.5 wt % of graphite. The lubricant is used in a method for producing a magnesium alloy tube via extrusion, and is especially useful to form implants such as stents while maintaining the biocompatibility of the magnesium alloy.
