Rexnord ZEP YF pillow blocks are mounted pillow block units with an integrated bearing, designed to support rotating shafts in power transmission equipment. The ZEP series combines a cast iron housing with a spherical roller bearing and a SHURLOK locking system that simplifies mounting on the shaft. They are used in conveyors, mills, pumps and process machinery where load and misalignment demand a robust, easy-to-maintain solution.

The ZEP YF designation is read in parts: ZEP identifies the family of pillow blocks with mounted bearing, YF indicates the housing and sealing variant, and the numbers that appear in each reference —such as ZEP5403YF, ZEP5407YF, ZEP5408YF, ZEP6403YF or ZEP6407YF— refer to the size and configuration of the assembly. The SHURLOK locking system is what gives the series its name and allows the bearing to be secured to the shaft without complications.

These pillow blocks are chosen in food and beverage plants, cement plants, steel mills, paper mills and agriculture, whenever there are drive shafts with moderate radial and axial loads. In Argentina they appear in belt conveyors, bucket elevators, mixers, centrifugal pumps and continuous process equipment. Their pillow block format facilitates anchoring to beds and metal structures, and the SHURLOK locking speeds up replacement during maintenance shutdowns.

To select the correct pillow block, take into account the shaft diameter, radial and axial load, rotation speed and working environment. The YF sealing protects against dust and moisture, but it is advisable to check lubrication and internal clearance before mounting. Alignment between pillow blocks is key: an uneven bed accelerates bearing wear. The SHURLOK system allows the lock to be adjusted on the shaft without hammering, which reduces the risk of damaging the raceway.

Regarding equivalences, mounted pillow blocks are interchanged between brands by shaft number, housing type and locking system, not by the commercial part number. Rexnord, Link-Belt and other lines offer alternatives with compatible dimensions, but the center height, hole spacing and shaft diameter must always be verified. If you need to replace a ZEP YF, send the complete part number and shaft dimensions: at MR Accesorios Industriales we will indicate the compatible alternative.

MR Accesorios Industriales distributes the Rexnord line and will quote the ZEP YF pillow block you need. Write to us on WhatsApp with the part number —for example ZEP5403YF or ZEP6407YF— and we will reply shortly with the quote. If the equipment works in a demanding environment, tell us the service conditions and we will advise you on the appropriate sealing and lubrication for your application.
