Tool Balancers, Load Balancers and Spring Balancers

Endo Spring Balancers
Endo Spring Balancers

ENDO Tool Balancers are the ideal addition to your assembly line or work areas. They make air and power tools "weightless" using adjustable spring tension set to equal the weight of the tools.

Hubbel-Gleason Spring Balancers
Hubbel-Gleason Spring Balancers

We proudly offer spring-driven tool balancers by Hubbel-Gleason. They keep tools within reach and reduce damage to tools by suspending them out of the way above the work surface.

Food Grade Tool Balancers
Food Grade Tool Balancers

These balancers have a buffed and barrel-polished casings or covers, food-grade grease on the spring, zinc plated upper hook, with stainless steel lower hook, plug, and hardware.

How to Balance a Power Tool

In this video we show how to balance a power tool using the Endo model EW-3 tool balancer that has a capacity range of 2.2 to 6.6 lbs.

Endo Balancer Tension Adjustment

In this video we show how to adjust the spring tension using the ratchet type or worm type for Endo models EK, EW, EWF, ETP, ELF and EWA spring balancers.

Spring Balancer Snap Back Prevention

In this video we demonstrate the functionality of the Endo EWA model spring balancers built-in safety feature called snap back prevention.

Why Choose an Endo Spring Balancer or Load Balancer?

Tool balancers, load balancers, and spring balancers are an ideal way to balance a constant load. Endo load balancers can be identified by their conical cable drum, which ensures that the retraction force remains virtually 'constant', throughout the full cable travel. As a result, the position is retained after the attached tool has been used. In addition, no noteworthy increase in retraction force occurs when delicate operations are being performed. As a result, Endo tool balancers permit fatigue-free working, even over prolonged periods of time.  Features include:

  • Endo spring tool balancers offer true zero gravity, with no drifting or strain
  • Tapered drum, quality springs and bearings provide smooth cable travel throughout the stroke
  • Cast aluminum case and forged swivel hook. Tension adjustment is easy and precise
  • Choose the size of the balancer using the total weight to be suspended (tool plus accessories). Try to use the upper zone of the balancer's load capacity data if possible.

EK, EW and EWF Series Standard Spring Tool Balancers

EWF series tool balancers 9 pound minimum range and above include an automatic brake and manual drum lock. In the event that the spring breaks, an automatic centrifugal brake engages and locks preventing damage to the tool. With the manual lock engaged, the drum will not rotate, the drum will not rotate. This allows for easy change out or tooling.
