Caster bearings play a very important role in the car, they connect the wheel and the frame, and can make the wheel roll smoothly, providing the support and stability needed for the car. Without the protection of grease, the bearings will lose their original function due to wear and tear, and even become a safety hazard when driving. Therefore, the role of caster bearing grease is to provide sufficient lubrication protection for the bearing, reduce the wear and heat caused by friction, prolong the service life of the bearing, and at the same time improve the safety and stability when handling.
Among the lubricating base grease, more manufacturers choose the relatively inexpensive lithium grease - the grease used in industrial machinery is grease, which is a paste, semi-solid, used in the internal friction part of the bearing, playing the role of lubrication and sealing.
Lithium grease has good anti-wear performance under normal temperature, low speed and low load conditions, and is suitable for low speed and high load mechanical equipment. However, under the condition of high temperature and high load, the lubricating effect of lithium grease will be greatly reduced, and the caster will be pushed hard and the bearing will not turn.
After weighing the pros and cons, Zhuo Ye chose molybdenum disulfide-based grease with higher price and longer service life for the caster wave plate and single wheel bearing as grease.
Molybdenum disulfide grease is a grease containing molybdenum disulfide, which is usually a blend of synthetic lubricating base oils and additives. Molybdenum disulfide is a black crystal that reduces the wear of bearings under high loads and high temperatures and has good anti-wear properties and extreme pressure properties.
Molybdenum disulfide-based grease has the advantages of good mechanical stability, rust and oxidation stability, thermal stability, water resistance and anti-wear properties, making the casters work properly in very harsh environments. Lithium grease also has certain extreme pressure performance, but compared to molybdenum disulfide grease, its extreme pressure performance is slightly inferior.
Let the handling more labor-saving, let the enterprise more efficient has been our constant pursuit of the sacred enterprise mission subtlety see the true chapter, Zhuo Ye manganese steel casters, from raw materials, excellence, only to better serve the majority of customers, Zhuo Ye would like to work with you in the future!
