Mast Guide & Chain Sheave Bearings
Mast Guide Bearings and Chain Sheave Bearings play an essential role in the ability to raise and lower the mast on forklifts and lift trucks. Ritbearing partners with several leading bearing product manufacturers to provide our customers with the specific bearing parts they need for almost any brand of equipment or construction vehicle.
What Are Mast Guide Bearings?
Mast Guide Bearings are known by different names including (forklift) mast guide rollers and (forklift) mast roller bearings. Regardless of what you call them, they have a specific, vital function. Mast Guide Bearings direct the forklift mast as they are raised and lowered. These bearings also attach the fork carriage to the mast rails so they can move smoothly.
Mast Guide Bearings are designed to be durable, able to withstand high radial loads, thrust loads, and intermittent shock loads. Because of this, they are developed with tight seals and a higher grease fill to reduce wear, prevent debris, and increase their lifespan. Unlike regular industrial bearings, the outer diameter of Mast Guide Bearings is placed directly against a steel mast rail and the internal design, composed of ball and roller complements, works to maximize the load capacity.
Mast Guide Bearings are manufactured in a wide variety of sizes to meet every application need. Ritbearing is proud to partner with leading manufacturers, including RCBD, to offer our customers aftermarket and custom designed Mast Guide Bearings, depending on their part requirements.
What Are Chain Sheave Bearings?
Like Mast Guide Bearings, Chain Sheave Bearings are known by several different names including chain rollers, chain pulleys, and chain guides. Chain Sheave Bearings are used in conjunction with Mast Guide Bearings in forklift and crane applications to guide and support rollers, move leaf and roller chains, and direct wire rope. These bearings guide chains through a channel or groove as the forklift masts move. These bearings are also vital for applications in parking lifts and heavy vehicle work lifts.
Chain Sheave Bearings are available in single, double row, and roller ball bearing arrangements and can be manufactured with or without an inner ring. Roller bearing designs are ideal for heavy loads at high speeds and can only be used for radial loads. Chain Sheave Bearings come lubricated and sealed to prevent contamination and to help maximize performance.
Chain Sheave Bearings are available in stock sizes as well as custom sizes and designs. Ritbearing partners with premier Chain Sheave Bearing manufacturers, like LI-BE, to provide our customers with high quality bearing options to meet every need and application.
