What bearings are on the Hotpoint-Ariston washing machine?
It is better to find out which bearings are on the Hotpoint-Ariston washing machine before starting the repair. This will make it possible to buy components in advance and not be interrupted during work. Ring sizes depend on the model. Let's figure out which spare parts are suitable for different Ariston washing machines.
Selecting bearings correctly
If you carefully approach the issue of selecting components, it will be difficult to make a mistake. Each model Hotpoint–Ariston match certain bearings and oil seal. They differ in the diameter of the internal and external holes, and in thickness. Therefore, look at the name of your “home assistant” and its serial number in the instructions or on the nameplate.
Many Ariston washing machines are equipped with bearings 203 and 204. In most cases, such rings correspond to an oil seal 25x47/64x7/10. These are the models:

There are also rare configurations of Hotpoint-Ariston models. These washing machines should be separated into a separate group:

For some Hotpoint-Ariston models, if the bearing assembly breaks down, you will have to change the tank assembly, these are the AQSL 85 CSI, AVL 80 CIS, AVL 100 CSI, AVF 109 EU, AQSF 129 CSI machines.
If you are afraid to buy bearings in advance, then you can go another way. Disassemble the washing machine and remove the rings. Show the salesperson in the store the old spare parts - he will measure the diameter, thickness and select similar parts.
At the same time, the manager will help with the selection of a suitable oil seal. It is also necessary to buy a special grease for SMA bearings - it will need to treat the rings, shaft and rubber seal. It is better to purchase original spare parts for Hotpoint-Ariston washing machines, rather than cheap analogues.
Why are there bearings in the washing machine?
An automatic washing machine with broken bearings will not be able to function normally. The bearing assembly “connects” the drum and the pulley - this allows the electric motor to spin the container to the required speed. Damaged rings cannot ensure normal operation of the mechanism.
Various signs indicate bearing failure:
strong noise, grinding and knocking during operation of the machine;
increased vibration of the SMA body;
drum play;
damage to the inner edge of the hatch cuff (an imbalance occurs, the laundry rubs against the elastic, deforming the seal);
There are rusty stains on the back wall of the tank.
For most Ariston models, the bearings are located in a cross, which is attached to the drum. The knot has two rings - inner and outer. The first is more powerful due to its larger diameter and increased thickness.The second one is located at the end of the shaft and performs an additional function, so it is smaller.
Some Hotpoint-Ariston washing machines have a mono-bearing. Such an element has two rows of balls at once, which eliminates the need for a second ring. There are few models with one double-row bearing, but they exist, and this must be taken into account.
The seal is very important
The oil seal must be replaced along with the rings. The rubber seal protects the bearings, preventing their premature wear. The gasket prevents water from getting inside the assembly. The dimensions of this part will also vary depending on the model of the washing machine.
When replacing SMA drum bearings, be sure to buy and install a new oil seal.
In the production of automatic machines today, three types of oil seals are used:
single-edged - they only prevent water from entering the assembly;
single-edged, complemented by anther. Here there is additional protection against debris and dirt getting into the unit;
V-RING are seals with a V-shaped profile. Such seals are installed only on vertical-loading machines. Due to their non-standard shape, they provide complete protection from water, dust and debris.
All modern sealing gaskets are complemented by a metal grill. When installing, it is important not to damage this reinforcing base. The original shape of the oil seal must be maintained.
The oil seal is placed on top of the bearing, in a specially allocated seat for it. The gasket seals the hole, preventing dust and moisture from getting inside the assembly. It is better to purchase original rubber bands, and not analogues from the Middle Kingdom. In this case, it is not advisable to save on components.
It is better to find out which bearings are on the Hotpoint-Ariston washing machine before starting the repair. This will make it possible to buy components in advance and not be interrupted during work. Ring sizes depend on the model. Let's figure out which spare parts are suitable for different Ariston washing machines.
