Deep groove ball bearing with seals or shields

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.Integral sea

Forklift chain bearings are critical components in the material handling industry, specifically within the operation of forklift trucks. These bearings are designed to handle heavy loads and high intermittent shock loads, which are common in forklift applications. Here's a detailed introduction to forklift chain bearings:

What Are Forklift Chain Bearings?

Forklift chain bearings, also known as mast guide bearings or roller bearings, are used in the mast and bracket sections of forklifts. They rotate in the rollers that are in constant contact with the masts under heavy load while the mast and the bracket move upward and downward. These bearings are essential for the smooth operation of the forklift's mast, which is the vertical assembly that enables the lifting and lowering of loads .

Key Features and Benefits

• Water-Resistant Grease: Forklift chain bearings are factory sealed and lubricated with water-resistant grease for longer life .

• Precision Ground Raceways: They are designed for maximum resistance to misalignment, impact, and wear .

• Heavy Outer Rings: These are specifically designed for maximum impact and wear resistance .

• Separable Tire/Sheave: Some bearings have a separable design for ease of maintenance and replacement .

Types of Forklift Chain Bearings

• Mast Guide Bearings: These guide the mast stages as the forklift mast is raised and lowered, ensuring smooth extension of each mast stage .

• Bracket Bearings: These run along the horizontal rails of the brackets, allowing for the left and right positioning of the fork attachment .

• Chain Roller Bearings: These guide the chain through profiled channels or recesses as the forklift mast is raised and lowered during operation .

• Lateral Thrust Roller: A vertical roller guide that prevents bending or twisting during telescopic extension and transfers the lateral load to the mast .

• Combined Roller Bearing: A bearing assembly consisting of a mast guide bearing with integral side thrust rollers, controlling the vertical and lateral movement of the mast .

Applications

Forklift chain bearings are used in various applications within forklifts, including:

• Guiding the telescopic mast section of forklifts.

• Supporting the carriage as it moves up and down the mast.

• Managing lateral loads and preventing twisting of the mast assembly.

• Guiding the leaf chain that raises and lowers the mast .

Specifications

Forklift chain bearings come in various sizes, with inner diameters ranging from 35mm to 55mm, outer diameters from 108mm to 149mm, and widths from 28mm to 45mm .

Maintenance and Longevity

Most mast guide bearings are lubricated and sealed to prevent contamination from getting into the rolling elements and raceways. They are maintenance-free under normal operating conditions, but re-lubrication is recommended for aggressive applications in tough working conditions .

In summary, forklift chain bearings are specialized components designed to handle the heavy loads and shocks associated with forklift operations. They come in various types to cater to different functions within the forklift's mast and carriage system, ensuring smooth and reliable performance.
