Rexnord ZAT series take-up units are mounted units ready to install in belt or chain drive systems. They integrate a bearing with housing and tensioning mechanism, which simplifies mounting and tension adjustment. They are used in conveyors, elevators and machinery where correct tension must be maintained to prevent misalignment and premature wear. MR Accesorios Industriales sells this line as an official brand.

The ZAT designation identifies the Rexnord take-up unit family. The series codes combine letters and numbers that define the size and configuration of the assembly: for example, ZAT421079 and ZAT431079 share the shaft diameter and vary in the mounting type; ZAT521119 and ZAT531119 correspond to a larger size. The numeric suffixes indicate standardized dimensions and fastening variants. To correctly interpret each reference, it is advisable to consult the Rexnord catalog table or send us the complete code on WhatsApp.

These take-up units are used in belt conveyors, bucket elevators, conveyor belts and chain systems in food, cement, mining, port and logistics plants. In Argentina, they are common in the oilseed and meat industries and in mineral processing plants. Their function is to maintain constant tension, compensate for belt or chain stretch and absorb small misalignments, extending the service life of the components.

To select the right take-up unit, take into account the shaft diameter, the radial and axial load, and the environmental conditions. Check the type of sealing: versions with single or double lip seals protect against dust and moisture. Lubrication can be with lithium or synthetic grease depending on the working temperature. During mounting, ensure the alignment of the unit with the shaft and the base; uniform tightening of the bolts prevents deformation. The internal clearance of the bearing must remain free to allow smooth rotation.

Rexnord take-up units are interchangeable with other brands that use equivalent designations, such as the Link-Belt ZAT series or similar references from SKF and FAG. Interchangeability depends on the critical dimensions: shaft diameter, hole spacing and center height. Always check these values before replacing a unit. If you need a compatible alternative, send us the original code and we will indicate the right option.
