REX ZT-7-9200 Spherical Roller Bearing Take-Up Block

The REX ZT-7-9200 Spherical Roller Bearing Take-Up Block is part of Rexnord’s ZT line of normal‑duty take‑up blocks designed to change the center distance between two parallel shafts in belt- or chain-drive systems. Housed in cast iron, this block accepts Rexnord spherical roller bearings and uses a threaded adjustment rod that is pinned in the eye of the block with a square or hex nut to set belt tension and spacing; expansion units are typically unnecessary due to clearances between guide bars and slots. Rex ZT blocks are fully self‑aligning with a double‑row roller bearing assembly to accommodate misalignment and vibration, helping maintain consistent take‑up action. Standard features include a 1/8 NPT grease fitting for lubrication, a clearance seal option, and compatibility with fixed take‑up or adapter configurations depending on frame. The ZT family covers shaft sizes from 3/4 in up to 7 in, with housing widths and slot dimensions engineered to fit Rex frames and compatible guide rails, and options such as caps and multiple seal types to suit a range of environments. In applications from conveyors to material‑handling lines, the ZT take‑up blocks provide reliable center‑distance adjustment, maintain belt tension under load, and integrate with Rex Spherical Roller Bearings within the broader Rexnord bearing ecosystem.
