Automotive Bearing – Ball Bearing

There are many types of bearings. Ball bearings are probably the most common type of bearing. They are found in everything from inline skates to hard drives. These bearings can handle both radial and thrust loads, and are usually found in applications where the load is relatively small. While tolerance is an important factor in the performance of a bearing, there are many other factors that also affect the suitability of a bearing to its application. Most ball bearings are single-row designs. Some double-row designs are available but they need better alignment than single-row bearings.

Automotive – Clutch Bearing / Clutch Release Bearing
An automotive clutch release bearing is a major part of auto vehicle. With the development of the auto industry , different types of clutch release bearings have been developed to meet different situation. It has developed from the type of low speed unit with non-self-aligning, free outer ring, cast iron sleeve, integral of the inner ring and the sleeve, today clutch release bearings with self-aligning, rotational inner ring, pressed cover, pressed sleeve or plastic sleeve have been developed to operate under high rotational speed reliably. It achieves components integrality by reducing the weight, cost and also offering a reliable operation and long service life.

Automotive Bearing – Wheel Bearing
If you want to your car to be smooth to drive, make the wheel bearing particularly one of your priorities. Wheel bearings hold your wheels on and allow them to spin properly. They are not an automotive component to be taken lightly. Most wheel bearings are sealed at the factory and don’t require replacement until, perhaps, 150,000 miles.

A bad wheel bearing will typically make grinding, whining or squealing noises, and you can often feel the looseness. Once the part fails, find immediate replacement for your wheel will not run properly without working sets of wheel bearings. Investing with premium and high grade wheel bearing replacements could instantly restore or re-establish the handling features of your vehicle. On your next scheduled replacement, you need to consult a qualified service technician to securely and properly fit heavy duty wheel bearing replacements. Turning to pros not only ensures proper alignment and installation, they could optimize the service life of your selected bearing replacements which could yield huge savings on less frequent replacement. In fact, you may replace your wheel bearing set more than once throughout its life efficiency for preventive maintenance. When you shop for your next scheduled bearing replacements, click on our 24/7 online shopping store so you can complete your general automotive needs by sealing premium wheel bearing deals any time or day.

By minimizing the friction that goes with metal to metal surface contacts as your car rotates, the functionality of the part is crucial to the overall performance of your vehicle. Keeping the part periodically greased or re-packed every two years, which is equivalent to 24,000-mile service, is essential to keep it in top notch working conditions. Proper greasing could also facilitate efficient flushing mechanisms to do away with any form of contaminants which can induce wearing and corrosion.

Timing Belt
For the most part, timing chains rarely need replacing and their properties allow for minimal timing variances even at lofty engine speeds. But chains can be far noisier when compared to timing belts. Timing belts on the other hand are quieter but tend to flex and require a bit more attention than chains do. Most timing belts should be replaced somewhere in the 60,000 mile range. This is especially important when dealing with interference engines in which both the pistons and valves occupy the same space at different times. Snap a belt, or even slip a couple of teeth and you can say goodbye to an otherwise perfectly running engine. Vibrant Performance’s adjustable timing belt tensioner gets rid of the flap the easy way.

Although it’s not necessary to replace the timing belt when installing Vibrant’s tensioner, now’s certainly a good time. The added tension on the belt could cause premature wear on a belt that’s seen better days. It’s important to mention here that Vibrant’s adjustable tensioner simply augments Honda’s original timing belt tensioner; it doesn’t replace it. Timing belt equipped engines make use of either a hydraulic filled, piston-type tensioner or a sliding bearing type tensioner. It’s important that the OEM-issued tensioner is in good working order and installed properly for the Vibrant piece to work correctly. When tensioning a timing belt using the OEM-supplied tensioner, you need to follow the service manual carefully.

Timing Belt Tensioner
In auto part aftermarket, there are different designs for timing belt tensioner. New timing belt tensioner design is based on the fixed motor principle that relies on a movable idler to properly tension the belt rather than tensioning with a motor mounted to a moving slider plate.

The new design takes the guess work out of changing and adjusting a spindle drive belt in the field. The tensioner is factory set to take the guess work out of setting drive belt tension. Pre-drilled and aligned tensioning brackets ensure the new belt is set to original specifications eliminating the possibility of over-tensioning a spindle drive belt- a very common cause of spindle failure.

Summary of Advantages
Increased rear bearing life due to the fact that it becomes no longer possible to over-tension the belt. The proper tension of the belt is determined and set at SETCO to provide optimal life and performance on a per application basis.
The new, robust cast aluminum mounting bracket (Belt Guard) offers a much stronger, more rigid structure to support the motor.
Increased belt life…proper tension eliminated premature belt wear.
Because the belt geometry is fixed by the idler, it reduces the time required for belt replacement.
Once the motor is aligned and mounted to its mounting plate, it never needs to be adjusted or moved. This eliminates the need for special equipment availability such as an over head crane.
The new design uses common parts for mounting the motor facing the spindle nose or towards the rear. The parts are used regardless of spindle rotation direction.
Idler Pulley
Idler pulleys are used to take up slack, change the direction of transmission, or provide clutching action. Idler pulleys are rollers that do not produce any mechanical advantage, nor transmit power to a shaft. Idler pulleys are used to lead a chain around a bend or to take up slack in a drive chain. There are many types of idler pulleys. Examples include an industrial idler pulley and a metric idler pulley. An industrial idler pulley is a pulley on a shaft that rests on or presses against a drive belt to guide it or take up slack specifically used in industries. A metric idler pulley is a pulley system that helps in connecting to distant points through an idler pulley. Idler pulleys are produced in a variety styles such as, V-belt, plain, flat, and cable style. V-belt idler pulleys are designed for strength and durability.

Pulley Tensioner
A pulley tensioner for applying torque or tension to a pulley includes a spring system configured to encircle the periphery of the pulley. The spring system is anchored to the pulley housing or some other fixed location. The spring system is made up of one or more coil springs which are wrapped around the periphery of the pulley. Where multiple springs are used, preferably each spring has a different spring constant and length. This allows the operator to select the desired tension depending upon the operating parameters of the printer. The applied tension may be further modified/tuned by using an additional spring member to anchor the spring system to the pulley housing or some other fixed location.

Clutch Bearings Industries Co., Ltd. ( was founded in 1992 by a management team with about 25 years of accumulated experience and know-how in the line, and the company has now become one of the top-two such suppliers in Taiwan.
Backed by seasoned expertise, a senior manager of CBI with experience and know-how, Kuo says that Clutch Bearings knows everything about making the finest, most durable automotive bearings using proper materials and manufacturing techniques. Its unmatched product diversity, with about 1,300 items for virtually all popular Japanese, American, European, and South Korean cars, means truly one-stop-sourcing for customers. On-site testing of all the products before packaging assures buyers of the highest quality and lowest defect rate. In addition, Kuo says the firm operates three warehouses that stock over 80% of the product line, meaning urgent orders are rarely backlogged.

Especially noteworthy is, according to Kuo, that CBI currently pours about NT$20 million (US$609,756 at US$1: NT$32.8) yearly into developing about 30 new products, particularly automatic tensioners. Such aggressiveness has left competitors behind in terms of the number of automatic tensioners CBI can supply.
