Extractors

For heavy truck bearings, choose hydraulic pullers that deliver a minimum of 15 to 20 tons of force with extra long jaws measuring 300 to 500 mm. This capacity allows you to remove hubs and bearings from 100 to 250 mm that are often seized due to corrosion and winter road salt.

Recommended specifications:

Hydraulic capacity 15 to 30 tons for heavy duty applications

Jaw length 300 to 500 mm for deep hub access

Maximum spread 250 to 400 mm for large diameters

Hydraulic system two speed pump for positioning and extraction

Sunex and OTC pullers provide proven durability for commercial fleets performing 10 to 30 extractions per month. Forged steel construction withstands extreme loads without deformation.

Équipement Industriel Polar recommends complete kits that include adapters for various hub configurations depending on the types of vehicles in your fleet.

To prevent damage, position the jaws under the inner race of the bearing, never on the cage or balls. Apply force gradually while checking centering and ensuring alignment perpendicular to the shaft.

Use penetrating lubricant 24 hours before extraction to reduce required force by 30 to 50 percent.

Recommended procedure:

Clean the extraction area and remove debris and corrosion

Apply penetrating lubricant 12 to 24 hours before removal

Position jaws under the inner race that is tight on the shaft

Apply force gradually while monitoring for signs of deformation

Heat the housing to 80 to 120 degrees Celsius if the bearing is extremely seized

Avoid striking the puller directly as impact can damage threads and jaws. Hydraulic pullers provide superior control of applied force compared to impact methods.

If excessive resistance remains, reassess the technique before continuing to prevent costly damage. Équipement Industriel Polar offers free technical support for complex situations.

Manual pullers use a simple lever action and generate 500 to 2000 pounds of force, sufficient for small bearings from 10 to 75 mm.

Mechanical screw pullers develop 2 to 10 tons through a threaded screw mechanism for medium size bearings. Hydraulic pullers generate 10 to 30 tons for the most demanding applications with precise pressure control.

Comparison by type:

Manual 500 to 2000 pounds price 20 to 80 dollars occasional use

Mechanical 2 to 10 tons price 150 to 600 dollars versatile regular use

Hydraulic 10 to 30 tons price 600 to 1499 dollars intensive professional use

Operator effort highest with manual lowest with hydraulic

Mechanical pullers offer the best balance for general repair shops performing 5 to 15 extractions per week. Hydraulic systems justify the higher investment for commercial fleets and industrial shops with more than 20 extractions per week requiring maximum productivity.

Équipement Industriel Polar recommends selecting based on workload and required capacity.

Lubricate threads and moving mechanisms monthly for heavy use and quarterly for moderate use.

Clean the jaws after each use to remove oil and metal debris. Visually inspect component integrity weekly to identify cracks or deformation requiring immediate replacement.

Recommended maintenance schedule:

After each use clean jaws and extraction screw

Monthly heavy use complete lubrication and detailed inspection

Quarterly moderate use lubrication and functional check

Annually full overhaul with replacement of worn components

Hydraulic pullers require annual oil level checks and air purging from the system. Replace jaws when wear or deformation exceeds 20 percent as reduced grip compromises safety.

Store in dry areas with a light anti rust protective coating on metal surfaces. Typical service life ranges from 10 to 20 years with proper professional maintenance.

Bearing pullers are covered by manufacturer warranties ranging from 1 to 3 years depending on the brand, covering defects in materials and workmanship.

Sunex, OTC, and Powerbuilt typically offer 1 to 2 year warranties on structural components and mechanisms. Jaws and wear parts carry limited warranties from 90 days to 1 year.

Warranty coverage:

Mechanical and hydraulic pullers 1 to 3 years depending on brand

Structural components covered for manufacturing defects and cracking

Jaws and accessories limited warranty 90 days to 1 year

Équipement Industriel Polar policy 30 day return on unused product
