CUDA automatic parts washers are built to handle demanding industrial cleaning running continuous cycles of pressurized hot water, detergent, and heat through every shift. The turntable assembly at the center of that process depends on two bearings to keep it rotating smoothly under load. The CUDA Turntable Upper Bearing is the component responsible for guiding and supporting the upper section of the turntable shaft, maintaining alignment and reducing friction throughout every wash cycle.
Over time, exposure to heat, moisture, and chemical detergents causes this bearing to wear. When it does, the effects are noticeable and if left unaddressed, a failing upper bearing puts additional strain on surrounding components. We supply the TT Upper Bearing (Part# 9.804-346.0) as a genuine replacement for all compatible CUDA series machines, with fast shipping across the USA.
The TT Upper Bearing sits in the upper section of the turntable shaft assembly inside the CUDA parts washer cabinet. Its function is to support rotational movement at the top of the shaft keeping the turntable centered, reducing lateral friction, and ensuring the wash basket stays stable and level as it rotates parts through the cleaning cycle.
While the TT Lower Bearing carries the primary vertical load of the turntable and basket, the upper bearing manages alignment. A worn upper bearing causes the shaft to run off-center, which puts uneven stress on the gearmotor, the lower bearing, and the turntable itself.
The bearing operates in a demanding environment temperature between 150°F and 170°F, high-pressure water spray, and continuous chemical exposure all of which gradually break down the bearing over time.
Identifying wear early prevents more costly secondary damage to the drive system. Watch for:
Replacing the upper bearing at first sign of wear restores smooth operation and protects the shaft, gearmotor, and lower bearing from accelerated wear.
The TT Upper Bearing (9.804-346.0) is compatible with all CUDA automatic parts washer series, including:
Not sure if this part fits your machine? Contact our team with your CUDA model number and we will confirm compatibility before you order.
In most cases, yes. The TT Upper Bearing and TT Lower Bearing (9.804-347.0) work as a pair. When one bearing reaches end of life, the misalignment and additional load it creates directly accelerates wear on the other. Replacing both at the same time during a single service window reduces future downtime and is the more cost-effective approach for most shops.
We supply both bearings individually or together making it easy to order everything you need in one go. View all CUDA Replacement Parts .

Q: What is the part number for the CUDA Turntable Upper Bearing?
The part number is 9.804-346.0. Use this number when placing your order to ensure you receive the correct part for your machine.
Q: What is the difference between the TT Upper Bearing and TT Lower Bearing?
The upper bearing (9.804-346.0) supports the top of the turntable shaft and manages lateral alignment. The TT Lower Bearing (9.804-347.0)sits at the base and carries the vertical load of the turntable and basket. Both must be in good condition for the turntable to rotate correctly.
Q: How do I know if the upper or lower bearing has failed?
A grinding or squealing noise from the upper part of the turntable assembly, or off-center basket wobble, often points to upper bearing wear. If the machine vibrates heavily or the basket sits unevenly under load, the lower bearing may also be involved. Contact our team with a description of the symptoms and your CUDA model number we can help you identify the correct replacement.
Q: How long do CUDA turntable bearings typically last?
Lifespan depends on cycle frequency, load weight, and operating conditions. In high-production environments, bearings may need inspection every 6 to 12 months. In lower-volume settings, they may last longer. Any change in turntable noise or rotation quality is a signal to inspect both bearings.
