Take-up frames in the Rexnord ZAT line arrive as mounted assemblies that combine a bearing, a housing and a tensioning element in one unit. They are installed on belt and chain drives to hold tension steady, take up stretch and absorb minor misalignment. Typical installations include conveyors, elevators and process machinery.

The code structure is worth understanding before you order. ZAT marks the family, and the digits that follow describe the size and the mounting arrangement. ZAT421079 and ZAT431079, for instance, are built around the same shaft diameter but differ in how they mount, while ZAT521119 and ZAT531119 belong to a larger frame size. The trailing digits point to standardized dimensions and mounting variants, so the catalog table is the best place to confirm a reference, or you can send the full number to our team.

These units suit belt conveyors, bucket elevators, conveyor belts and chain drives in food processing, cement, mining, port and logistics operations. Their job is to keep tension constant, compensate as belts or chains stretch and soak up small alignment errors, which helps the surrounding components last longer.

Selection comes down to a few inputs: shaft diameter, radial and axial load, and the conditions where the frame will run. Look at the sealing arrangement as well, since single or double lip seals are what keep dust and moisture away from the bearing. Grease choice follows operating temperature, with lithium or synthetic options available. At installation, line the frame up with the shaft and the base, tighten the bolts evenly to avoid distortion, and leave the bearing internal clearance free so it can rotate smoothly.

Frames from this line can replace units from other manufacturers that use equivalent designations. What decides whether a swap works is the critical dimensions: shaft diameter, hole spacing and center height. Confirm those values before you pull a unit out of service. If you want a compatible option, give us the original part number and we will point you to the right one.
