VEVOR Blind Hole Bearing Puller Set 16-Piece 6–59mm — Slide Hammer & Counterstay

VEVOR's 16-in-1 Blind Hole Bearing Puller Set is a complete slide-hammer and counterstay kit designed to extract internal bearings, races, and seals from blind or tight bores without damaging surrounding parts.

This kit combines a 3.1 lb slide hammer, ten expandable collets, three screw adapters, a U-shaped counterstay and an M10 pin bolt to remove stuck inner races and seals sized from 6 mm to 59 mm (1/4" to 2-1/3"). Built from heat-treated, high-hardness steel with anti-rust coating and quenched collets, the set is engineered for repeated shop use where access is limited and traditional pullers can't grip the inner surface.

How does the kit remove bearings from blind holes?

The tool works two ways: by using the slide hammer to deliver controlled inertia and by employing the U-shaped counterstay to lever components out when there is room to brace against the housing. The expandable collets fit inside the inner race and tighten with the pin bolt so the hammer pulls the part out evenly without slipping.

• 10 expandable collets cover 6–59 mm internal diameters.
• 3 screw adapters allow secure attachment to different insert sizes.
• 3.1 lb sliding hammer delivers impact extraction without hitting the housing.
• U-shaped counterstay gives a mechanical alternative where hammer use is impractical.

What sizes and components are included in the 16-piece set?

The set includes ten collets, three screw adapters, the slide hammer assembly, a U-shaped counterstay and an M10 pin bolt—totaling 16 pieces. The range covers small pilot inserts up to larger collets so a single kit handles a wide spread of inner race dimensions commonly found in cars, motorcycles and industrial equipment.

• Collet sizes precisely span 6 mm to 59 mm for incremental fitting.
• Three screw adapters match different thread and bore situations.
• M10 pin bolt secures collets for stable extraction.
• Slide hammer and counterstay provide two extraction options for varied clearances.

How durable and reliable is the construction?

Collets are forged from Cr40 steel and quenched at high temperature to resist wear, deformation and repeated impact. The major components receive heat treatment and an anti-corrosion finish so the kit stands up to shop environments, heavy tapping, and prolonged use without losing alignment or performance.

• High-temperature quenched collets to reduce wear and bending.
• Heat-treated pins, counterstay and adapters for extra hardness.
• Anti-rust coating protects surfaces in humid or oily workshops.
• Slide hammer rated for heavy impact extraction cycles.

When should I use the counterstay instead of the sliding hammer?

The U-shaped counterstay is the preferred option when space restricts hammering or when a controlled levered pull reduces risk to nearby components. Use the counterstay in narrow bores or when tapping the slide hammer could cause collateral damage to brake, transmission or engine housings.

• Choose counterstay for tight engine bays or chassis clearances.
• Use sliding hammer for straightforward blind-hole extractions where room permits.
• Switch methods depending on access and sensitivity of surrounding parts.
• Both methods share the same collets and adapters for quick swapping.

Who is this for: technicians, home mechanics and maintenance crews who regularly remove inner bearing races, seals or pressed-in bushings from blind bores will find this VEVOR kit useful. It’s aimed at users who need a versatile, workshop-grade extractor set that covers multiple diameters and gives both impact and lever removal options without resorting to destructive methods.
