The Timken GW-Series greasable wide insert bearing is engineered for the most demanding agricultural applications where re-lubrication is essential for survival. Featuring a wider body than standard inserts and a grease fitting for field re-lubrication, the GW-Series is the bearing you reach for when equipment runs long hours in dusty, high-temperature conditions. Available in square and machined bore configurations from 1-1/16″ to 2-3/4″.

What separates the GW-Series from standard inserts is the grease path — a channel machined into the inner ring that allows fresh grease to be pumped directly to the ball/raceway contact zone, flushing out contaminated lubricant and extending bearing life dramatically. In West Texas cotton harvest conditions where fine fiber debris and dust are constant, the ability to re-grease without removing the bearing is the difference between finishing the season and replacing equipment mid-harvest.

Lambear Industries carries GW-Series inserts for the farmer and equipment operator who maintains their machinery properly. These bearings cost more than standard inserts, but they last significantly longer when properly greased on a maintenance schedule. Select your bore shape, then your part number below.
