Maybe:
select
substring ('150mm LD AD Asp XR Macro', '^[\\d-]*mm' ) as BASE_NAME
, substring('150mm LD AD Asp XR Macro','^[\\d-]*mm (.*)$') as SUFFIX;
select
substring ('28-70mm LD AD Asp XR Macro', '^[\\d-]*mm' ) as BASE_NAME
, substring('28-70mm LD AD Asp XR Macro','^[\\d-]*mm (.*)$') as SUFFIX;
etc...
