Abstract
A bearing support for cylindrical lift pumps wherein the support comprises an elongated carriage positioned transversely of the pump, a pair of spaced parallel rollers on said carriage and pivots for supporting the carriage on a base. With the pressure of the pump on the rollers, the carriage will tilt to permit the rollers to maintain line contact with the pump and the carriage is arranged to provide for independent deflection of the rollers to compensate for deviation of the pump from a true cylindrical configuration.
