Precision Components

Precision components are crucial to the performance and longevity of any machinery or equipment. At SAPPARTS, we specialise in providing top-quality precision components. Wether you require precision components for industrial machinery or heavy engineering, at SAPPARTS our components will meet specific needs and exceed expectations.  

Our precision components are made using high-grade materials such as alloy steel (SAE 4140, 100Cr6, SAE8620, C-45, 20MnCr5, 55Si7, SCM45, etc.) to ensure excellent strength, durability, and reliability


Bushings are a critical component in heavy engineering applications, serving as a low-friction bearing between two moving parts. They are used in a wide range of heavy engineering applications, such as construction machinery, mining equipment, and industrial manufacturing.
One of the most common heavy engineering applications of bushings is in hydraulic cylinders, where they help to minimize friction and wear between the cylinder and piston. They are also used in axle pins, suspension systems, and gearboxes to reduce wear and provide a smooth and efficient operation. Typical heavy engineering applications of bushings include:

High Load joints on excavators (Boom foot,  Boom cylinder foot, pivot, stick nose) and the  joints of the bucket linkage

>Joints of front loading attachments for  agricultural tractors: cylinder, bucket, fork, etc.

> Arm, bucket and cylinder joints of wheel  loaders

> Front axle joints on agricultural tractors

> Joints on front axles of trucks

> Pivot Bushings of rod end cylinder  for 
hydraulic hammer used in mining  application

> Joints of rollers and of chain links of  conveyors
> Pivot joint arm on container stacker for  port handling

> Pivot & other joints of hydraulic crushers

> Pivot Joints of cable-operated clamshell  bucket


We serve a range of industries, including construction equipment OEMs, such as excavator, backhoe loader, and dozer manufacturers. We also cater to off-highway equipment OEMs, including crane, compactor, and rock-drill manufacturers, as well as agriculture equipment OEMs, such as harvester, tiller, and tractor manufacturers.
In addition, we provide our expertise to the transmission industry, catering to gear box, drives, and conveyor manufacturers. At SAPPARTS, we are committed to pushing the boundaries of innovation to provide our customers with the best possible solutions for their specific needs

Open ended and closed ended groves carved inside the bore of Bushings provide path for lubricating oil and grease ensures the appropriate lubrication in between mating parts and improves service life of the bush. These bushings are also provided the ani-friction graphite based compound Molybdenum di-sulphide MOS2 and Tungsten di-sulphide WS2

MOS2 Coating

These bushings are also provided the anti-friction graphite based compound Molybdenum di-sulphide MOS2 and Tungsten di-sulphide WS2. Life-more than 50% can be  achieved as tested under standard  conditions compared to the normal  case hardened steel alloy bushings.

WS2 Coating

Tungsten di-sulfide  suspensions has atomic adhesion  properties, which helps to form the  film on the surface as a composite  coating, thatoutperforms in terms  of longevity in Tribological run and  sliding contact wear resistance  due to its properties like hardness  and lubricity in asingle film.
