Take-up Units

ZWA take-up units are an efficient means of tensioning the pulleys of conveyors and elevators.

Each take-up unit consists of a ZWA split roller bearing in a swivel cartridge (see page 515) mounted in a cast iron sliding unit. Two basic configurations are available - the`push` type and `tension` type as illustrated.

Tension Type Take-Up Unit

Usually a ZWA take-up will be mounted at each end of the shaft. Up to and including 90mm/3?" bore size the standard arrangement uses two expansion (EX) bearings, with axial location provided by blanking plates and ball thrust bearings.

Above 90mm/3?" bore size the standard arrangement uses two fixed (GR) bearings and plain blanking plates, if a through-shaft or different method of axial location is required, please consult our technical department
