SHIMS

What is SHIMS?

The best way they can be described is essentially as a ‘spacer’ or ‘washer’ which is a thin piece of material used between objects to fill small gaps and spaces. While filling this gap it allows for a better fit, level surface and supports the object better, prolonging the lifespan of the machine / components. It has a large impact on the function, performance, and longevity of a piece of equipment. Although easy to overlook, they have the potential to greatly reduce costs.

Riddhi Siddhi Impex is a leading manufacturer, supplier and exporter of pipe fittings, forged fittings, tube fittings, dairy fittings, valves,Shims,Washers, Fasteners and flanges.

Shim Properties

Brass includes aspects such as non-sparking properties, which make brass very good for using in applications that have chemicals and explosive gases. Brass is also supple and has unique acoustic properties, so it can be used in sectors that manufacture electrical appliances. Elsewhere, aluminium is popular with industries that require them to be non-magnetic; aluminium does not ignite easily, it has excellent thermal and electrical conductivity, reflects very well, and is corrosion resistant.

Also when manufacturing them in plastic they are known for their durability. Most plastic can resist corrosive materials like oil. So they’re well known to customers for their long lasting application and are also very adaptable. They’re easy to trip and manipulate, which gives customers a far greater range of applications.

The different applications are endless, but a few typical uses are automotive, aerospace, construction, packaging, medical equipment and many more.

Types of Shims we manufacture

1-Alignment Shims

Essentially, an alignment shim is a washer, or small, thin piece of appropriately chosen material designed to make parts fit more accurately. Additionally, it helps to keep different components of a machine aligned. Therefore, reducing wear, keeps things stable as well as, allows a machine to function to the best of its ability. So, when parts are aligned, machines run more smoothly.

Alignment shims are regularly used in the automotive industry with one example being when you change the camber or caster of your car; here you might find that you car’s wheels have misaligned over time.
This happens in any machine when it is used often and it is something to keep an eye on as misalignment can cause significant problems if left unchecked. When this happens in a car or any machine, an alignment shim can be inserted into the appropriate place in order to help reduce metal distortion and warping.
They are also commonly used in assembly and weld fixtures to assist with general alignment and accuracy.

2-Assorted Shim Packs

Looking for pre-cut shims in assorted sizes? Then our Assorted Shim Packs might well be for you. The packs are available in CS4 shim steel, Brass CZ108, Stainless Steel 304 grade and Polyester Plastic Shim. All in a range of different thicknesses

3-Brass Shim

As a material, brass is ideally suited to many of the jobs our products are used for. The brass shims are cut to a range of particular sizes, ensuring precision in both thickness and dimension. Consequently this saves you both time and effort when you’re working.
By leaving the measuring and cutting of the brass shim to the professionals, you can rest assured that they will always be perfectly flat and undistorted. Therefore, they will perform exactly as they ought to. Due to the fact our manufacturing process operates at such a high standard, you know that every product we produce will be safe and secure.

4-Keyway Shims

Keyway shims are thin, precisely engineered pieces of material, typically made from stainless steel, brass, or plastic, used to fill gaps or spaces in keyways. A keyway is a slot or groove cut into a shaft and a corresponding part, like a hub or gear, which accommodates a key. The key locks these parts together, allowing for torque transmission while preventing relative motion.

At Stephens Gaskets, we understand that keyway shims are primarily used to adjust the fit and alignment of the key within the keyway, ensuring a secure and accurate connection between components. They are indispensable in maintaining the integrity and efficiency of mechanical systems by preventing relative motion and ensuring proper torque transmission.

5-Laminated Shims

When it comes to laminated shims, they have several important features that make them perfect for certain applications. For example, they have many layers, which are able to peel back to create the desired thickness. In order to achieve the layers either metal foil or a composite is bonded, using pressure, to create a rigid structure. Furthermore, these bonded layers mean the shims respond well in a machine environment. It also means they are easily adjusted by taking off another layer.
Laminated shims are regular components within the automotive and aerospace industries. Similarly, they are common in any application where rotating shafts and sliding surfaces need to remain parallel or where accumulated tolerances need to be controlled. As well as, where the dimensions of a machinery part can change by crushed forces or sliding wear.

6-Nickel Shims

A nickel shim is a thin piece of nickel (often in a circular shape) which has been designed to fit in between components inside a piece of machinery. Over time, components inside machines can get worn away, which can have an impact on the alignment. With loose fitting components, the risk of wear and tear is much higher, and if left for too long, can severely impact the performance and lifespan of the machine.
By fitting in a shim, you can achieve a tighter fitting alignment. Therefore, protecting the components from moving around too much and causing unnecessary damage. What’s more, shims are much cheaper to replace than an actual part inside a machine. So, if the nickel shim does bear some damage after a while, it will still be more cost-effective to replace.

7-Nylatron GS Shim Washers

Nylatron GS is a specially enhanced version of Nylon 66. The material contains specific measurements of Molybdenum Disulphide (MOS2). The addition of this means that Nylon GS has much better self-lubrication properties compared to the unfilled Nylon 66. Components such as washers that are made from Nylon GS are much stiffer, harder, and more dimensionally stable than those made from standard Nylon.

Properties:

The key advantage to Nylatron GS is its self-lubrication. The addition of molybdenum disulphide (MoS2) to Nylon means that the material has extra lubricity. As a result, parts made from Nylatron GS can function with little or no lubrication. This etra lubricity also means that parts will often have a longer service life – making them highly cost-effective. Nylatron GS shim washers also have fantastic mechanical strength and fatigue resistance. Alongside this, they have great wear resistance and electrical insulating properties.

8-Peelable Shims

A shim is a thin piece of material (usually rounded) that is fitted inside a piece of machinery. Machine components often have specified adjustment allowances for assembly purposes, however a peelable shim can be the cost-effective solution for this.

As opposed to an adjustment allowance, you can peel the shim down to the size at the time of assembly. As a result of a peelable shim, you can easily obtain an accurate adjustment and alignment in your machinery during both the original assembly and in maintenance. All of this can be achieved without the need of equipment or grinding, the user can simply peel one layer after another on the shim until they have achieved the perfect thickness.

The shim will always remain a uniform thickness that is smooth, clean, and parallel. The foil that you have peeled off will not be able to be used due to the fact it deforms whilst you are peeling it off.

9-Phosphor Bronze Shims

Often referred to as 2.1020, the phosphor bronze material is BS PB103 phosphor bronze, which contains 6% tin. As a result of this, the alloy offers excellent wear resistance and higher strength properties than PB102 material. PB103 is also well known for its fantastic tarnish resistance. Additionally, PB103 material is highly corrosion resistant to a wide range of liquid and chemical environments – including paper and textile manufacturing plants. Many components are made in this material including precision machined components. Here at Riddhi Siddhi Impex, we can produce PB103 washers and PB103 shims cut to your exacting specifications.
Phosphor bronze has many different standards but PB102 and PB103 will often be compared. When it comes to the components we make, when comparing a PB102 shim or PB102 washers with PB103 ones, the latter will usually triumph. Put simply, the alloy offers a much greater strength and wear resistance than PB103 phosphor bronze.
