With the development of the world economy, the rapid development of urban infrastructure and transportation infrastructure, the market has a corresponding increase in demand for construction machinery and equipment, and the consumption of bearings for construction machinery is also increasing day by day. Bearings with reliable quality and excellent performance can improve the efficiency of construction machinery. Reduce downtime, thereby creating greater value.
To understand which bearings are used in construction machinery, we must first understand what are there in construction machinery?
18 categories of products in the construction machinery industry, including excavating machinery, soil shoveling and transporting machinery, construction hoisting machinery, industrial vehicles, compaction machinery, piling machinery, concrete machinery, steel and prestressing machinery, decoration machinery, rock drilling machinery, pneumatics Tools, railway line machinery, military engineering machinery, elevators and escalators, special parts for engineering machinery, etc.
There are many types of construction machinery bearings
— Deep groove ball bearings: rotating motors, reducers
— Angular contact ball bearings: reducer
— Needle bearing: gearbox, rotating motor, travel deceleration system
— Self-lubricating bearings: on various components such as the chassis traveling mechanism, body parts, and hydraulic components. Including bimetal boundary lubrication rolled bearings, metal-based self-lubricating bearings and metal plastic self-lubricating rolled bearings, etc.
