DAYUAN Bearing Separator Puller Set 12pc — 5-Ton Capacity, 2" & 3" Splitters, Heat-Treated

DAYUAN 12-piece Bearing Separator Puller Set is a heavy-duty 5-ton capacity kit designed to split and extract 2" and 3" bearings, gears, and flywheels safely and precisely.

This compact, organized kit gives mechanics, hobbyists, and mobile technicians the tools to remove press-fit bearings and separate components without damaging shafts or housings. All 12 parts are drop-forged and heat-treated for toughness, finished in black oxide for corrosion resistance, and stored in a blow-mold case sized for shop benches or vehicle trunks. The set combines two sizes of bearing separator jaws with hex push-puller legs, a cross bar, and a heavy forcing screw so you can tackle common pulling tasks on cars, ATVs, snowmobiles, and light industrial equipment.

How does this set remove bearings without harming the shaft?

Using mirror-opposed separator jaws, the kit grips the inner racer or component behind the bearing surface, allowing force to be applied to the housing rather than the shaft. That prevents nicks and scoring while concentrating pull force where it’s safe.

• Two splitters (2" and 3") clamp behind bearing shoulders for secure engagement.
• Forcing screw presses against the cross bar to pull evenly and straight.
• Hex push-puller legs spread load to the housing instead of the shaft.

What parts are included and when would I use each one?

The kit contains 12 specific components to cover common removal scenarios: two sizes of bearing separators, two sets of push-puller legs, a cross bar, and a heavy forcing screw. Use the smaller separator for compact bearings and the larger one for wider races; the legs adapt to different flange depths and puller configurations.

• 2" and 3" bearing separator jaws for small and medium separators.
• 4" and 5" hex push-puller legs to convert the unit into a two- or three-arm puller.
• 5" puller cross bar and 6-1/4" forcing screw for high-torque extraction up to 5 tons.

Is the kit durable enough for frequent workshop use?

Each piece is drop-forged and heat-treated to resist bending and wear during repeated high-load pulls. A black oxide finish adds corrosion resistance, and the heavy-duty blow-mold case protects tools in transit and keeps parts organized between jobs.

• Drop-forged construction for greater tensile strength and impact resistance.
• Heat-treated components maintain shape under repeated loads.
• Blow-mold case (15" x 9.7" x 2") with latches for secure storage and transport.

How much force can this puller set handle and what safety steps should I follow?

The set is rated for up to 5 tons (4.5 metric tons) of pulling capacity, suitable for most light automotive and small equipment applications. Always center the forcing screw, use the correct separator size, and wear eye protection to reduce risk from sudden releases of stored energy.

• Rated capacity: up to 5-ton (4.5 MT) for heavy extractions.
• Align separators and forcing screw to prevent side-loading and part damage.
• Use protective eyewear and gloves; secure workpiece in a vise or fixture.

Who this tool is for: the DAYUAN 12-piece Bearing Separator Puller Set is aimed at DIY mechanics, professional technicians, and mobile repair specialists who need a portable, robust solution for removing small to medium press-fit bearings, pulleys, and flywheels. If you work on cars, ATVs, snowmobiles, lawn equipment, or light machinery and want to avoid replacing shafts or housings after removal, this kit provides the adaptable parts and storage convenience to keep common pulling jobs fast, safe, and repeatable.
