Shaft Misalignment causes vibration, failure of bearings, seals, etc and equipment damage.

Shaft Alignment Kit is used for Accurately Aligning the Shafts of Pump and Motor.

• It consists of an Aluminium vee Block that can be clamped on the Hub of the coupling by wing nuts.
• The kit has two precision spirit levels in the vee block to get accurate indexing of 90°, 180°, 270° and 360°.
• Suitable extension pins, dial holder pins, clamps are provided to take care of different spacer lengths between couplings.
• There is a facility of using two Dial Gauges, one for measuring Radial misalignment and other for Axial.

While installing rotating equipment, Shims play a crucial role in accurately positioning the equipment during shaft alignment.

Lack of shim of proper size and thickness leads to improper alignment. This in turn causes vibration and ultimately leads to unplanned breakdowns and enormous downtime expenses.

• Flat, burrfree shims make the job of alignmenT accurate and reliable.
• Easy to fit and remove.
• Made up of corrosion resistant Stainless Steel (SS 304), allowing reuse.
• Round edged to avoid cuts.
• Clearly marked thickness on each shim for quick identification.
• Quick and safe insertion and removal of shim using Tab Hole.
• Saves a lot of time, labor and money wasted by hand cut shims.
• Accurate alignment improves equipment performance and hence it’s reliability.

Features:

• Easy to convert, 2Arm or 3Arm Self-Centering Hydraulic Pullers.
• Selfcentering jaws for Quick and Firm Grip.
• Selfcontained Hydraulic Pump and Puller Body with Integral Safety Valve.  
• 360° Rotary Socket.
• The extension rods can be used for extra reach when necessary. 

The best way to avoid unwanted stresses when assembling interference-fit parts is to heat the outer part just enough to produce a temporary clearance.

Induction heaters allow this to be done precisely, quickly and efficiently.Bearings having an ID > 50 mm must be hot mounted as the interference between the shaft and the bearings is more. Cold mounting or use of methods such as open flame, oil bath or hot oven must be avoided as they are inefficient, less controlled and do more harm than good to the bearings.Induction Heater is an excellent method for heating and installing rolling bearingsand ring-shaped metal parts such as gearwheels, sprockets, sleeves, etc with both speed and care.

Features:

• Automatic Demagnetisation
• Compact & Light Weight
• Thermal Overheating Protection
• Can Be Operated in Time Mode or Temperature Mode
• Intelligent Micro-Controller Based Electronics
• Four Step Power Setting

Heavy Duty Mechanical Pullers to dismount any machine element including bearings, pulleys, couplings and gears without damaging them.

Features:

• Jaws remain coplanar over the entire width thus ensuring Full Grip over the machine element requiring extraction.
• Facility of locking puller jaws to avoid any Slippage while extracting
• Gunmetal ring provided to eliminate damage to spindle
• Specially designed Tommy to apply extra torque
• Rotating center to reduce damage to shaft
• All parts made from high grade alloy steel, duly hardened & precision ground to provide Heavy Load carrying capacity, Excellent Reliability & long life.

Advantages of Modular Design:-

• Optional Accessories like Chisel type Jaws, to extract Bearings having very low backside clearance, extra holder to increase reach, Fan jaws to remove Motor Fans, can be easily fixed & removed. THIS MAKES THE PRODUCT VERSATILE.
• Any individual component can be individually replaced, whereas in many other pullers no replacement of individual components is possible.

The Trisection plates grip behind the Inner and Outer Rings of the Bearing and helps extract them both simultaneously preventing the Inner ring to get stuck on the shaft. 

Prevents bearing damage and minimizes the force required for dismounting.

Can be used with any 3Jaw Puller.

Mounting bearings by hammering or brute force dents their inner/outer races as well as alters the set clearances.

Bearing Fitting Tool Kit is used for quick and precision mounting of bearings, while minimising the risk the bearing damage.

It comprises of 36 Impact rings, 3 Impact Sleeves and 1 Nylon Mallet all assembled in a suitable carrying steel case.

The Aluminium Alloy Impact Sleeves and Ultra High Molecular Weight Polyethylene (UHMW-Pe) Impact Rings are made to fit into a diverse set of combinations.

The impact rings and sleeves are marked for clear visual identification with a selection chart in each kit to identify easy mounting.

With the above assembly one can mount over 200 different bearings from 10mm to 60mm ID with precision and accuracy. Each sleeve can accommodate about 200 mm length projecting shaft.

Benefits:

• Availing longer life of bearings resulting in huge savings.
• Ensuring accurate alignment and even distribution of mounting forces.
• Avoiding sparking as well as dirt being injected into the bearings.
• Quick and trouble-free mounting with ease.

Features:

• Easy to convert, 2Arm or 3Arm Puller.
• Selfcontained Hydraulic Pump and Puller Body with Integral Safety Valve.  
• 360° Rotary Socket.
• Spring loaded live centering nut for easy job (removable).
• Four stages of foldable and removable handle which saves the handle force during operation.
• The extension rods can be used for extra reach when necessary
