The ZST series take-up mounted bearing is a ready-to-mount assembly that combines a bearing with a housing designed for take-up functions. It is used to guide and tension chains, belts or bands in transmission equipment, where alignment and fastening are critical. MR Accesorios Industriales supplies this Rexnord line in Buenos Aires, Argentina, and advises you on choosing the model for your application.
The ZST series designation is read as an alphanumeric code that identifies the housing type and its variants. In examples ZST125403Y18 and ZST125407Y18, the ZST prefix indicates the take-up housing family; the following digits encode the size and housing features, and the Y18 suffix indicates a specific sealing or mounting configuration. To select the correct replacement, send us the full part number shown on the part or on your equipment drawing.
These take-up mounted bearings are used in industries such as food, cement, mining, paper and materials handling, in chain conveyors, bucket elevators, conveyor belts and belt drive systems. In Argentina, they are commonly found in processing plants, mills and materials handling equipment that operate under high demands of dust, moisture or temperature.
To choose the right take-up housing, take into account the type of sealing required for the environment (dust, water, washdowns), the bearing internal clearance and the lubrication method. Assembly must ensure correct shaft alignment and firm housing fastening to prevent vibration and premature wear. The ZST series supports configurations with different seal types and locking systems; ask us about the variant that best suits your equipment.
Rexnord take-up mounted bearings interchange with those of other leading brands, as long as the main dimensions, the housing type and the mounting system match. When looking for a replacement, check the shaft diameter, the distance between mounting centers and the sealing type. MR Accesorios Industriales helps you find the right equivalence between different brands and resolve the installation without errors.
