A bearing system for a sand container to be vibrated on a vibrating table in a lost foam casting installation, the system comprising:

• a plurality of bearing members projecting upwardly from the vibrating table, each bearing member having an upwardly tapered frusto-conical surface;
• a corresponding plurality of frusto-conical bearing sockets on the bottom of the container;
• wherein the frusto-conical sockets are formed in a material resistant to wear;
• and wherein the bearing members each comprise a body of wearable material which forms the said frusto-conical surface, secured to the vibrating table by means of a respective releasable fastening element elongated in an essentially vertical direction and having an upper head shaped to transmit and distribute a compression pre-load into the body.
