The device that connects the vehicle's suspension to a bearing system that allows the wheels to move freely is known as the wheel hub. The hub units have the greatest direct impact on the vehicle's handling. Their failure might result in an unexpected shift in the vehicle's trajectory and the possibility of an accident.

TMI TATSUMI wheel hubs and hub bearings are composed of high-quality steel and have hardened running surfaces to provide maximum hardness and strength. To optimize friction and yield, ball bearing tracks are meticulously polished. Furthermore, our bearings employ JIS (Japanese Industrial Standards)-compliant balls, which adds to a longer bearing life.

A unique gland seal is used in TMI TATSUMI brand bearing units to provide dependable protection against the impacts of unfavorable external conditions, dirt, and abrasive particles. A high-performance grease is also used to reduce internal friction and related wear and tear, and it is meant to last a long period without needing to be replaced.

For direct torque transfer from the gearbox to the drive wheels, constant velocity joints (CV joints) are utilized. CV joint failure eventually results in the car's inability to operate, however such tragic effects seldom occur right away. As a result, if a noise during movement (typical crunch) is detected, it is important to evaluate the quality of these hinges promptly and, if required, replace them with new ones as soon as possible.

TMI TATSUMI constant velocity joints are made from high-quality steel in specialist factories, and their working surfaces are hardened using high-frequency currents to provide the requisite hardness and service life. Internal friction is reduced to a minimum by the high-quality lubricant provided with the CV joints, which adds to the unit's long-term efficient functioning on the automobile.

CV joints operate in harsh circumstances beneath the hood of a moving car. Anthers created specifically for this purpose protect hinges with similar angular velocities from dirt, abrasive particles, liquids, and other contaminants. This boot is crucial because if it is broken or leaks emerge, the CV joint will rapidly fail (rubbing surfaces will be worn out) and will need to be replaced.

TMI TATSUMI constant velocity joint dusters are composed of high-quality synthetic rubber that maintains its properties even when exposed to extreme temperatures, chemically active chemicals, abrasives, and severe mechanical stress. Anther clamps are constructed of stainless steel, ensuring that the device is simple to assemble and that the anthers are securely held in place during their operation.

Because they are in direct touch with road grit and dirt, bitumen particles, water, gasoline, and oil at a range of temperatures, the drive shafts of front-wheel drive automobiles are subjected to large torsional stresses and function in extremely difficult circumstances. As a result, the materials utilized, the surface polish, and the overall quality of the drive shafts are all subject to stringent criteria.

The automobile will simply not be able to drive if at least one drive shaft breaks.

Automotive drive shafts are manufactured under the TMI TATSUMI trademark for use in a wide range of automobiles. They are made from high-quality steel that has undergone thermal surface hardening (hardening) and anti-corrosion treatment. Furthermore, the use of high-quality efficient grease, dependable synthetic rubber anthers, and stainless steel clamps ensures that these parts and the device as a whole operate for a long time.

The clutch in an automobile is a vital component that is subjected to high temperatures and varying mechanical stress during operation. The clutch's job is to momentarily separate the car's engine and transmission. Partially failing clutches provide considerable issues in vehicle operation (for example, slipping clutches, partial clutch disengagement), higher fuel consumption, and fast gearbox and engine wear. The clutch's complete breakdown renders vehicle operation very difficult (failure to engage or disengage the clutch).

TMI TATSUMI clutch kits are composed of high-quality steels, and a specific friction material composition is utilized for dependable torque transfer from the engine. The petals of the diaphragm spring are shot blasted to produce a harder surface layer, greatly extending the part's overall life.
