Timing belt replacement should be left to the pros. It can be complicated to replace the timing belt on most engines, especially those with dual camshafts or lots of drive accessories that need to be removed.

Timing belts are a maintenance item; they can wear out and fail without warning. Check your owner’s manual. It pays to know which kind of engine you have and the recommended replacement intervals.

In many cases, special tools are needed to correctly install a timing belt. Plus, other parts may need replacing. Timing gear indexing (precisely aligning the camshaft gears and crankshaft gear to the manufacturers specs) is critical. Even if one gear is one tooth “off,” engine valve timing will be out of sync, damaging your engine or causing it to run rough.

Are you looking for a bearing that's watertight (2RS), dusttight (ZZ), with increased clearance (C3-C4-C5) or in a specific material such as stainless steel or ceramic? At 123Bearing, we offer you a vast choice of these products with different specifications to suit your needs. In fact, we specialize in online bearing sales and offer a wide range of products. JTEKT, SKF, ZEN, FAG, NSK, NTN, SNR, INA, TIMKEN, NKE are just some of the brands we offer. You can select the product you need according to part number or dimensions, brand, bearing type, load capacity or speed.

Today, there are a multitude of ball bearings available. They can be single- or double-row, radial contact or angular contact. Single-row radial contact ball bearings (also known as deep groove ball bearings) are the most commonly used, as they offer the best value for money.

These suffixes mean "with 1 or 2 sheet metal deflectors", for dust-tightness. At 123Bearing, we specify whether bearings are sealed on 2 sides with "ZZ".

The ABEC standard is used to classify bearings according to their machining tolerance. This standard is regularly called into question because it does not include certain technologies that are important for guaranteeing correct operation, both in terms of efficiency and bearing life. 123Bearing therefore makes little use of this standard.

Engines come in two configurations: Interference and non-interference. When a timing belt fails the camshaft(s) stops turning and the valves stop moving, but the crankshaft still rotates for a few seconds. An interference engine has insufficient clearance between the valves and pistons. Because the crankshaft keeps rotating, pistons will slam into any valves stuck in the open position, causing catastrophic engine damage. A timing belt failure in a non-interference engine will leave you inconveniently stranded.

These suffixes mean "with 1 or 2 rubber seals". This seal protects the bearings from splashing water. At 123Bearing, we use the number "2" to indicate that the bearing is sealed on both sides.

Many timing belt covers are difficult reach, making visual access to the belt impossible. If you can’t get to the cover without taking half the engine compartment apart, leave it to the pros to determine if your vehicle’s timing belt needs to be replaced.

If you can get to the belt, it should be taut, with about a 1/4-in. to 1/2-in. deflection when pressed with your thumb along its longest run between gears. It should be smooth and flat (no rounded edges), not glossy or shiny, have no chunks missing, be free of large cracks or peeling and show no signs of fraying. Small surface cracks are okay, but spider cracking on the surface signals extreme wear.

In most cases, bearing identification is straightforward. The reference is often inscribed directly on the bearing's inner or outer ring, or on the seal/metal flange.

Ball bearings are a necessary part of many applications and industries. Whether on the wheels of your cars, bicycles, machine tools or agricultural equipment, they are indispensable components. When choosing these bearings, you need to take into account a number of factors:

Consult a repair manual to see if you can easily remove the timing belt cover. A repair manual is different from an owner’s manual because it lists step-by-step repair procedures. Most auto parts stores carry vehicle repair manuals, and many lend them to their customers at no cost.

If this is not the case, it will be necessary to take the dimensions of this product. To do this, you need to measure the inside diameter, outside diameter and thickness. We recommend that you always use a caliper to take your measurements, so that they are as accurate as possible.

The rings of these products are subjected to many shocks on a narrow surface. For this reason, they are generally made of wear-resistant chromium steel. They can also be made of stainless steel (inox) if required. The cage that holds the balls can be made of steel, polyamide or even brass. This product is known for its ability to withstand high speeds and low loads, unlike roller bearings, which can withstand high loads and lower speeds.

Engines using timing chains can also be interference or non-interference engines. Timing belts are usually molded from rubber or neoprene, have strong fibers or steel running the length of the belt (similar to a tire) and produce less noise than metal timing chains. This makes them strong and durable. But they don’t last forever.

These products meet the requirements of a multitude of applications. In fact, you can find these product models on the following applications:

Whichever type of bearing you choose, it can be either open or sealed, depending on your requirements. Unsealed steel ball bearings can withstand temperatures of up to 120°. Standard 2RS models, on the other hand, can withstand temperatures of up to 80°. The advantage of using sealed bearings is that they are lubricated for life and require no special maintenance.

The ball bearing is a mechanical system that enables rotation between a rotating and a fixed element. The single-row ball bearing consists mainly of two rings, a cage and several balls in a single row. In fact, this bearing has an inner ring, an outer ring and the cage that holds the balls in position relative to each other.

There is no simple answer. First, check your owner’s manual for the recommended maintenance schedule. Some manufacturers recommend replacing the timing belt every 30,000 miles, while others suggest 120,000 miles. Several other factors should be part of the equation when considering replacing a timing belt, including:

Have you ever wondered if it's time to replace a timing belt? For the answer, listen to your engine and follow your vehicle's maintenance schedule.

A timing belt is similar to an engine drive belt, except timing belts have teeth. In many engines, timing belts have replaced metal timing chains (similar to a bicycle chain) connecting the camshaft and crankshaft gears. The camshaft and crankshaft must work in perfect harmony, called valve timing, during the four-stroke combustion cycle (intake, compression, power, exhaust).

Means "increased internal clearance". Often referred to as high-speed, this means that the bearing is designed for high speeds and moderately high temperatures. CAUTION: a bearing with increased internal clearance will not operate optimally at low speeds. We invite you to refer to the technical data sheet of the products you are looking for to find out their RPM limit.

These suffixes indicate that the cage (the part of the bearing that holds the balls apart) is made of a polymer material. Usually made of glass-fiber-reinforced polyamide.

The price the pros charge to replace a timing belt ($350 to $1,500) varies depending on the engine, make, model and year. It also matters whether an independent repair shop or dealer’s service department makes the repair.

Timing belts themselves are relatively inexpensive but can easily cause thousands of dollars of damage if they break while the engine is running.

Whether you or your mechanic replaces the timing belt, it’s always a good idea to replace these other components at the same time.

It pays to buy a timing belt kit rather than the individual items. Depending on the specific make and model, a typical timing belt kit ($100 to $500) includes a timing belt, timing belt tensioner, idler gears or pulleys, water pump, gaskets, O-rings and seals and other hardware.
