NTN SPAW / SPW Heavy Duty Spherical Roller Bearing Units


Cost savings and pressure to work faster and get the equipment running as efficiently as possible are challenges for most maintenance departments. Under such pressures, installation of open bearings in split-style housings only promotes chances of contamination entering the bearing or lubrication at the time of installation.
 

Keeping an open bearing assembly clean during installation is not an easy challenge and can only lead to repeated bearing replacement in the future. Tasked with the challenge to avoid failure, the second main SP/SFC design achievement is simplified installation to avoid mistakes. The unit is supplied completely assembled and consists of a one-piece pillow block (SPA/SPW style) or flanged housing (SFC style) with the MX-W insert that is sealed and lubricated in NTN’s clean bearing manufacturing environment. The series’ one-piece ductile housings avoid mixing of caps with bases plus integrated snap rings avoid any requirement for additional fixing rings, thus each inventoried unit can easily adjust to a fixed or free assembly. Reducing components and steps required at installation has proven to avoid initial setup errors while a completely enclosed insert allows continuous work to commence at any given time in the surrounding environment without concern of bearing contamination.
