CMTOOL 3-Jaw Pilot Bearing Puller Kit — CR-V Steel, 16–38mm Range, 50–95mm Stroke

The CMTOOL 3-jaw pilot bearing puller kit is a compact, forged CR-V steel toolset engineered to remove blind and pilot bearings between 16mm and 38mm with a stable three-jaw grip.

This compact kit is built for mechanics, hobbyists, and technicians who need a reliable method to extract small to mid-size bearings from housings where the bearing inner race is accessible. The set combines a three-jaw design with heat-treated carbon steel components and a corrosion-resistant coating for repeated workshop use. It is meant for bearings with diameters from 16mm to 38mm and offers a pull stroke range of 50mm to 95mm. While robust, the tool is not intended for heavily rusted or fused bearings without prior lubrication or rust treatment.

How does the three-jaw design protect bearings during extraction?

The three-jaw layout applies even radial pressure around the bearing's inner surface, reducing the chance of slippage or uneven force that can deform the bearing. This balanced grip improves stability while you rotate the central forcing screw to draw the bearing out.

• Uniform pressure from three contact points reduces damage risk
• Forged jaws maintain shape under load for consistent gripping
• Coated steel surface resists corrosion for long-term performance

What bearing sizes and stroke lengths does this puller support?

The CMTOOL puller covers a practical range for many automotive, motorcycle and light industrial bearings. It accommodates inner diameters from 16mm (0.63") up to 38mm (1.5") and offers an adjustable pull stroke between 50mm (1.97") and 95mm (3.74").

• Fits bearings with 16–38mm diameters
• Pull stroke adjustable from 50mm to 95mm for varied depths
• Rotate the central screw to generate controlled extraction force

What materials and construction features ensure durability?

Key load-bearing parts are forged from high-carbon and CR-V steel, followed by heat treatment to increase strength and toughness. The jaws receive a corrosion-resistant coating, helping the tool withstand workshop conditions and resist surface wear during repeated use.

• Forged, heat-treated carbon steel for high strength
• CR-V components for toughness and wear resistance
• Protective coating on jaws to prevent rust and surface wear

How should I use the tool safely for best results?

Keep the tool aligned and balanced when extracting a bearing to avoid bending the hook rod or marring the component. Avoid using the puller on heavily rusted bearings without first applying penetrating lubricant or freeing the part mechanically; extreme corrosion can exceed the tool's intended use.

• Center the jaws around the inner race before applying force
• Rotate the forcing screw steadily—avoid sudden, high-impact loading
• Pre-treat corroded bearings with penetrating oil; don’t force fused parts

Who is this for: Technicians, DIY mechanics, and small-shop owners who work on cars, motorcycles, small agricultural machines, or general mechanical assemblies where pilot or blind bearings between 16mm and 38mm need safe extraction. The CMTOOL kit is suited to users who want a compact, durable puller for repeated use, provided the parts are not heavily rusted or seized beyond the tool's mechanical limits.
