How the YWS Split Yoke Bearing Assembly Works
Conventional tapped-in and stud type bearings can be difficult to remove for routine pump lubrication, bearing replacement, and other maintenance. The split-yoke bearing housing on the YWS pump can be accessed quickly and easily–often without removing the pump.
The submerged bearing assembly’s split sleeves are clamped across the pump’s column using through bolts. These typically loosen and remove easily. In cases of age or corrosion, the bolts can still be accessed to be burned, sawed or chiseled off. This is impossible with other bearing assemblies where bearing access would require complete pump removal.
Once the through bolts are removed, bearing maintenance and/or replacement can be completed quickly, without distributing the pump casing and impeller. The open bearing arrangement permits easier inspection and complete lubrication or flushing.
Bearing material choices include micarta, ni-resist, cutless rubber, babbit, bronze, stainless steel, cast iron, teflon, or any other available material suitable for the particular application. The method of bearing lubrication can be grease, water, or lubrication by the process liquid being pumped.
