Caster bearings play a very important role in driving, they connect the wheels and the frame, can make the wheels roll smoothly, provide the support and stability needed for driving. In caster rolling, wheel bearings are in constant force and friction, if there is no grease protection, the bearings will lose their original function due to wear and tear, and even safety hazards in traveling. Therefore, the role of caster bearing grease is to provide adequate lubrication protection for the bearings, reduce wear and heat caused by friction, prolong the service life of the bearings, and at the same time, improve the safety and stability of handling.
In the domestic lubricating grease, more manufacturers choose relatively inexpensive lithium grease due to most of the grease color is yellow, we habitually called grease. Industrial machinery on the use of grease is grease, is a paste, semi-solid, used for bearing internal friction part, play a lubricating and sealing effect.
Lithium grease has good anti-wear performance at room temperature, low speed and low load conditions, and is suitable for low speed and high load mechanical equipment. But in high temperature, high load conditions, lithium grease lubrication effect is greatly reduced, there will be casters to promote laborious, bearing does not turn and so on.
After weighing the advantages and disadvantages, Zhuo Ye manganese steel casters chose the more expensive and longer service life of molybdenum disulfide-based grease as the caster disc and single wheel bearings as the grease.
Molybdenum disulfide grease is a grease containing molybdenum disulfide, which is usually a blend of synthetic lubricant base oils and additives. Molybdenum disulfide is a black crystal that reduces bearing wear under high loads and high temperatures and has good anti-wear properties and extreme pressure properties.
Molybdenum disulfide based grease has good mechanical stability, rust and oxidation stability, thermal stability, water resistance and anti-wear properties, which enable the casters to be used normally in very harsh environments. Lithium grease also has certain extreme pressure performance, but compared with molybdenum disulfide grease, its extreme pressure performance is slightly inferior.
In recent years, with the emergence of anti-wear additives, the lubricating performance of grease has been improved, and grease has been widely used. In the purchase of casters, caster bearing grease should also become part of the purchase, do not look at this little bit of grease, he is likely to be in your daily work, so that your handling more labor-saving, so that your business is more efficient.
