VEVOR Blind Hole Bearing Puller Set 16-in-1 — Slide Hammer Kit with 6–59 mm Collets & Counterstay

This compact 16-piece kit combines a 3.1 lb sliding hammer, ten expandable collets, screw adapters, a U-shaped counterstay, and an M10 pin bolt to tackle stuck bearings and seals in confined engine, gearbox, or hub assemblies. Built from heat-treated, high-hardness steel with an anti-rust finish, the set balances strength and corrosion resistance for shop and field work.

How does this set remove blind-hole bearings without access to the outer race?

The kit uses expandable collets that fit inside the blind-hole race, then expand and lock as the pin bolt is tightened, creating a secure grip. You can pull parts using the sliding hammer for inertia extraction or use the counterstay method when space is limited.

• Ten collets cover 6–59 mm diameters for inner-race engagement.
• M10 pin bolt expands collets for a tight internal bite.
• Sliding hammer delivers controlled impact force for stubborn parts.
• U-shaped counterstay offers leverage when hammering isn't feasible.

Which components are included and what sizes does it support?

The set contains 16 total pieces: ten split collets, three screw adapters, a slide hammer assembly, one U-shaped counterstay, and an M10 pin bolt. Collets and adapters accommodate a wide range of inner-diameter bearings, seals, and sleeves commonly found in automotive and industrial applications.

• Collet coverage: roughly 1/4" to 2-1/3" (6–59 mm).
• Three screw adapters for different thread engagements.
• 3.1 lb slide hammer for momentum pulls.
• Counterstay for narrow or recessed workspaces.

Is the kit durable enough for regular shop use and high-impact pulls?

Yes — collets are made from Cr40 steel and undergo high-temperature quenching to resist wear and deformation under load. Other load-bearing parts receive heat treatment and an anti-rust finish so the tool maintains integrity through repeated heavy use.

• Cr40 quenched collets resist cracking and shape loss.
• High-hardness steel construction resists bending under impact.
• Anti-corrosion coating extends service life in humid environments.
• Pin bolts and adapters heat-treated for long-term hardness.

When should I use the sliding hammer vs. the counterstay method?

Use the sliding hammer when you have enough clearance and need momentum to free a stubborn part; it applies repeated impact energy through the pilot assembly. Choose the U-shaped counterstay when working inside tight recesses or where controlled steady pull without hammering is safer for surrounding components.

• Sliding hammer: best for stuck or corroded races requiring impact.
• Counterstay: ideal for confined areas and delicate nearby parts.
• Swap screw adapters to match thread engagement and pilot alignment.
• Expand collets via the M10 pin for secure internal gripping.

Who is this for: mechanics, restoration hobbyists, and maintenance technicians who regularly remove blind-hole bearings, seals, bushings, and sleeves will find this VEVOR kit useful. It suits automotive, motorcycle, ATV, and light industrial repair tasks where inner-race extraction is needed, offering a range of collet sizes and two extraction modes to adapt to different repair scenarios. The hardened, rust-resistant construction and compact assortment make it practical for both mobile service vans and fixed workshops.
