whether the sliding bearing with thicker wall thickness has advantages

Read about how wall thickness in plain bearings affects heavy-duty applications, and whether or not it’s truly necessary.

Reasons for the use of thick walls in metal bearings

These bearings are usually made of solid material. If special machining is carried out on its inner diameter (such as making lubrication grooves), it is obvious that the bearing must have a certain wall thickness.
Plus, it’s hard to imagine that a 100mm ID, 105mm OD metal bearing (according to ISO 3547-1) could be pressed into a housing bore without the risk of bearing deformation or bearing damage.

Viiplus Oil-free bearings are highly recognized in agriculture

Agricultural machinery products It can go as deep as 5 to 30 centimeters underground, thus fully loosening the arable land and preparing it for the next season’s sowing. During use, however, there may be large rocks in the path of the tractor and its farming equipment. The agricultural machinery has overload protection design. During normal operation, the teeth working on the ground will automatically dodge backwards and upwards, and then automatically return to the working position.
The general solution of metal bearings makes it necessary for workers to add lubricating fluid at the moving teeth and other wear-prone points every day, and the lubricating time can be as long as an hour or longer, depending on the size of the cultivator. If a large number of lubrication points are not adequately lubricated, the resulting lack of lubrication can lead to considerable problems such as corrosion, greatly increased bearing point wear, and ultimately damage to the shaft and housing bore.
However, VIIPLUS graphite inlaid bearings are self-lubricating and maintenance-free, can withstand high loads, and because there is no need to add lubricants, they will not adhere to dirt during operation, thus greatly improving the service life of sliding bearings.

What effect does reducing wall thickness have on wear?

In my opinion, thin walls are a disadvantage only if the entire wall thickness is used as a “wear reserve”. In this case, the life of the thick-walled bearing will of course be longer if the wear rate is the same.
But frankly, are there applications that can tolerate millimeter-level wear? Not in a planter, for example. Because that would have catastrophic consequences for seeding patterns.
No customer will accept huge bearing play on his machine!
If the metal bearings are badly worn, things can go badly. Wear will almost certainly have an effect on the shaft as well, such as worn bearings that can seize.

Thick-walled oil-free bushings do not make bearings more wear-resistant

Thick walls do not make plain bearings more wear-resistant!
Additional advantages of Viiplus self-lubricating thin-wall bearings: lower bearing costs, less material used, and shorter injection molding cycles. Thinner walls also enable narrower tolerances.
