Mast and Chain Guide Bearings Intro Fork lift trucks are employed in almost every manufacturing and shipping facility where lifting or movement of materials is required. An essential part of a fork lift truck is the channeled lift structure which is commonly called the mast. Ball bearings are a basic part of the mast as they guide and retain the forks in the vertical channels. Chain Sheave roller bearings which facilitate the lifting and lowering of the mast are also an important part of the entire upright system.

NTN-BCA® Mast Guide Bearings are available in 24 styles. D r

Fork lift trucks handle loads ranging from light, bulky material to heavy loads in excess of 4,000 pounds. Mast Guide bearings are specifically designed to withstand the heavy radial loads required in this type of application. 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. All Mast Guide and Chain Sheave bearings are sealed and factory lubricated with a water resistant grease to prevent contamination of the balls, rollers and raceways. NTN-BCA® manufacturers a number of mast guide bearing sizes. Most are basic single and double row construction.
