Mast Guide Bearings

Mast guide bearings are specifically designed to withstand the heavy radial loads required in Fork Lift Truck applications. Mast guide bearings have heavy section outer rings which serve as rollers, or guides for the carriage in the mast channels. The configuration of the outer ring is designed to fit the contour of the mast channel. In some cases, the lift truck manufacturer provides a sleeve for a replacement double row bearing. Some of these bearings have outer rings which are cracked allowing the insertion of extra balls, greatly increasing load capacity. In conjunction with the heavy radial loads experienced, thrust loading is also present which tends to cause misalignment. The internal construction of Mast guide bearings resists misalignment of the outer ring.  

Bearing Service carries inventory of many common mast guide bearings, and can often offer considerable savings over purchasing replacement bearings through fork lift manufacturers or service companies.
