A lens carrier (10) is disclosed for use in a stage lamp. The lens carrier (10) supports a lens (26) in alignment with the lamp axis (12) while permitting limited movement of the lens along the lamp axis to focus the lamp toward the light. First and second members, (14, 22) define facing cylindrical surfaces (20, 24). A bearing assembly (28) having resilient deformable ball bearings (34) is positioned between the cylindrical surfaces to maintain alignment of the lens on the lamp axis and permit the second member and lens to move along the lamp axis relative to the first member while maintaining the alignment.
