PRODUCTS
We manufacture various parts used in wide range of industries. Provide us with drawings or samples and we will create the product to your specification.




WORM GEAR
Worm gears are often used when large speed reductions are required. The reduction ratio is determined by the number of starts of the worm and number of teeth on the worm gear. Worm is made of hard metal while the worm gear is made from relatively soft metal such as aluminum bronze.
SPROCKET
Sprocket, or sprocket-wheel, is a profiled wheel with teeth, or cogs, that mesh with a chain, track, or other perforated or indented material. Sprockets are used either to transmit rotary motion between two shafts where gears are unsuitable or to impart linear motion to a track.
HELICAL GEAR
Helical gears are gears with slanted tooth . In comparison to spur gears, they have the larger contact ratio and perform in quietness and less vibration and able to transmit larger force. A pair of helical gears has the same helix angle but the helix opposite helix hand.
SPUR GEAR
Spur gears are the most common gears that transmit motion between two parallel shafts. Tooth surfaces of the gears are parallel to the axes of the mounted shafts, thus there is no thrust force created in the axial direction. Because of the ease of production, these gears can be made to a high degree of precision. However, they have a disadvantage in making noise.




GEAR RACK
Gear racks are used to turn rotating motion into linear motion. A gear rack has straight teeth cut into surface of a square bar or round rod and operates with a pinion, which is a small gear meshing with the gear rack.
SENEBOGEN GEARBOX PLANETARY INTERNAL RING GEAR
Internal gear is a gear with its teeth cut in the internal surface and meshes with the planetary spur gears. Commonly found in gearbox.
GEAR BOX PLANETARY GEAR (SENEBOGEN)
Planetary gears are used in gear box for transmission of power. It often consists of 3 or more gears(planet gear) rotating around one gear(sun gear).
MOTOR COUPLING
A coupling is used to connect two shafts together at their ends for power transmission. It provides for the connection of shafts that are manufactured separately such as a generator and motor, to provide for disconnection for repairs or alterations.




PULLEY ROLLER
Rebuilding of pulley roller inner/outer diameter so the bearing will fit tightly.
HYDRAULIC CYLINDER
Hydraulic cylinder is a mechanical actuator that produces a unidirectional force through a unidirectional stroke. It consists of components like piston, cap, barrel, chrome shaft, hydraulic seals, fittings to make up a whole cylinder.
TELESCOPIC HYDRAULIC CYLINDER
Telescopic cylinder are used when a long distance of output motion is required. Its shaft are hollow section and smaller diameter shaft is retracted in it. Commonly seen in tipper truck and waste truck.
PIN & BUSH
We machine pin & bush according to customer specification and required material.




TOW HOOK
We supply tow hook used on machines like OTC (open top container), metal bins, waste compactors etc. Produce accordingly to required length and angle.
PISTON
The function of the piston is to divide the pressure zones inside the cylinder. The piston is machined with grooves to fit elastometric or metal seals and bearing elements. These seals can be single acting or double acting.
HEAD CAP
The main purpose of the head cap is to enclose the pressure chamber from the one end. The head contains an integrated rod sealing arrangement or the option to accept a seal gland. The head is join to the body by threading, bolts, or tie rod.
ALUMINIUM CASTING
Aluminium casting is lightweight, high dimensional stability for complex shapes and thin walls, good corrosion resistance, good mechanical properties, high thermal and electrical conductivity, retains strength at high temperatures




CABLE ROLLER
We are able to fabricate cable roller in accordance to customer specific dimension and need.
CHUCK JAW
Chuck jaw are often used for tight clamping of objects. They are often seen equipped in sheet piling vibro hammer. Parts will be sent for heat treatment to prolong useful life.
PULLEY
A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and cable or belt.
NYLON, PLASTIC, PE SHEET
Cast nylon is often use for parts that are expose to frequent wear and tear from movement. We will machine to customer specific dimension.




STAINLESS STEEL STRAINER
Strainer fabricated in accordance to customer specification.
PUMP LINER
.
PUMP REPAIR
Pump casing will experience wear and tear. We provide pump restoration service to restore back to its original dimension.
GEAR SHAFT
Gear shafts provide the rotation that allows one gear to engage with and turn another and contain gear teeth integrated into the shaft.




CONVEYOR ROLLER
Roller for conveyor belt system.
With sprocket welded on one end it can be be chain driven
FLANGES
A flange is used for connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.
TOOLS & EQUIPMENT MODIFICATION
We provide modification and repair of your equipment to suit your needs
MOTOR SHAFT
Motor drive shaft fabricated to your required dimension. Common used in PTO pump and marine pump application




SHEAVE PULLEY
A sheave (pulley wheel) is a grooved wheel used for holding a belt or rope and incorporated into a pulley. Sheaves can be used to redirect a cable or rope, lift loads, and transmit power.
BORING RIG ROTARY FIBRE
Customised size fibre installed in boring rig rotary to prevent metal to metal contact and improve parts durability.
SKATES
Hydraulic powered gear driven skates used for moving of machineries.
VIBRO HAMMER HELICAL GEAR

LASER ENGRAVING
Laser engraving is the practice of using laser to engrave an object. The technique does not involve the use of inks or toolbits that contact the engraving surface and wear out
BEVEL GEAR
Bevel gears are gears where the axes of the two shafts intersect and the tooth bearing faces of the gears themselves are conically shaped. Bevel gears change the axis of rotation of rotational power delivery and are widely used in mechanical settings.
WORM SHAFT
A worm drive is a gear arrangement in which a worm meshes with a worm wheel. Its main purpose is to translate the motion of two perpendicular axes or to translate circular motion to linear motion
