How to install an oil seal on a washer

Why is the washer equipped with an oil seal? 
This component prevents water from entering the bearings from the drum cavity. It takes considerable ability and understanding in the area of automatic machine construction to perform an element's diagnosis and, if necessary, its replacement, which are labor-intensive processes. You can install the gland yourself, but you must first carefully read the handbook to understand the steps involved and the primary issue with tearing apart the machine.
This component serves as a sort of seal between the drum and the shaft, and its importance cannot be overstated. Thanks to the oil seal, liquid cannot enter the washer shaft or bearings. The component, a rubber ring with a specific diameter, appears to be relatively straightforward.
When manufacturing automatic machines, washer equipment manufacturers use oil seals of various diameters; the diameter of the ring depends on the particular model of the washer and the features of the unit tank's design. In order to determine the type of oil seal you need for installation, it is advised to disassemble the machine and remove it from the case before purchasing the item.

In what way should the seal be lubricated?
Due to its position in the system and its function, the stuffing box is continually exposed to friction and the effects of temperature changes. The rubber may develop fractures during a protracted operation, which will surely result in the part's loss of functionality. This effect is detrimental to the sealant. Because of this, it is important to lubricate the oil seal's surface and preserve it as soon as possible. The life of the element will be greatly extended by routine use of specific greases.

How should the ring be greased? 
Be sure to carefully examine the composition's properties while selecting it. Grease of a high caliber must adhere to specified standards.
withstand dampness. It needs to have organic particles with a water-repellent property.
They have a high heat tolerance. During the friction process, the side of the seal closest to the drum will overheat, so it is crucial that the lubricant doesn't lose its qualities after heating.
Do not contain any aggressive substances, such as chlorine or other substances that could ruin the ring's surface.
thick in consistency. This is required for a thick covering of sealant rubber on the gland bush. You can machine bearings as well.

pgrbbf,

I wholeheartedly agree with using sealed bearings, not only do they retain lubrication within, but they also stop the ingress of grit and sawdust, probably the best reason for their installation. When overhauling my vintage car I used sealed bearings whenever possible they also stop leakage of lubricant onto nearby parts brake shoes in my case, and wood surfaces in your case.

It's a wonderful thought. Sealed bearings would make life much easier.

I'm not an engineer, I'm a woodworker, and I only have my common sense to rely on, no experience in this field at all. But I find it hard to imagine that it is such a simple swap from a system where you continuously renew the lubrication around the bearings, to one where you have a small amount of grease that will not be changed until the bearing fails will give exactly the same bearing life. I am happy to be proven wrong. I'm trying to learn.

Recommended tension for a bi-metal blade is 25,000 to 30,000 psi. A 3/4" blade will need something like 800Ib of force to create that tension. (I'm not great at physics, so please don't criticise, this is what I have always been told)

A wheel bearing on a car would be quite a nuisance to continuously grease. A bandsaw is a lot easier.

Use sealed bearings. The technology has moved on since your ancient bandsaw was made. You think your bandsaw will stress bearings more than a 300kg motorcycle cornering at 250kmh? Those are sealed and last for years.

And adding more grease to a bearing does not increase its load capacity or anything else. The reason they had grease buckets on bearings was because they did not have good seals so they just kept adding grease to make up for the lost grease. It was a messy world back then.

Get the best name brand bearings you can access, such as SKF, FAG or Timken. Cheap Chinese bearings will not last as long or run as smoothly.

And if you want you could probably find a modern seal to fit that recess, just measure the ID, OD and thickness. If you fit that along with sealed bearings it would help keep sawdust away from the bearing and its built in seals and those sealed bearings will last forever.
