DAYUAN Bearing Separator Puller Set 14-Piece — 2" & 3" Separators, Forged Heat-Treated Kit with Forcing Screw

DAYUAN 14-piece bearing separator puller set is a professional-grade kit for safely splitting and extracting bearings, gears, and pulleys from shafts.

This complete bearing separator and puller kit brings together robust separators, a cross-bar, forcing screw, and a molded blow-case so you can tackle removal jobs with control and safety. Components are forged and heat treated for durability, and the set’s modular design allows use of individual parts or combinations depending on the task. It’s built to handle stubborn press-fit parts while protecting component surfaces.

How does the separator puller remove bearings without damaging parts?

The split-style separators slide behind the bearing or gear and clamp around its outer diameter, creating even pressure as the forcing screw pulls the component off the shaft. This approach avoids prying that can mar housings or shafts. Proper alignment and gradual tightening ensure the load is distributed evenly.

• Two separator sizes (2" and 3") to match different shaft diameters
• Split plates clamp behind the race to prevent slipping
• Forcing screw and cross-bar convert axial force into controlled extraction

What parts are included and how can they be combined?

The kit contains separators in two sizes, a 5-inch cross-bar, a 6-1/4-inch forcing screw, and accessory hardware, all stored in a blow-mold case. You can use each separator on its own with external pullers, or join the cross-bar and screw to perform standalone extractions. The modular pieces make the set flexible for varied workshop needs.

• 2" and 3" bearing separators for different component widths
• 5" cross-bar mates with the 6-1/4" forcing screw for direct pulling
• Components compatible with standard bar pullers and legs

What construction features improve lifespan and performance?

Critical load-bearing parts are forged and heat-treated to resist bending and wear during repeated extractions. Threaded elements are made to withstand high torque, and the separators have precision-machined faces for consistent clamping. The blow-mold case protects tools from corrosion and organizes the kit for quick access.

• Drop-forged steel halves for enhanced strength
• Heat treatment for improved toughness and fatigue resistance
• Protective blow-mold case for storage and transport

How should I use this kit safely and effectively?

Always match separator size to the bearing and seat the split halves squarely behind the race. Tighten the forcing screw a little at a time to keep pull force centered, and use lubricant on threads to reduce galling. Support shafts and housings to avoid bending or misalignment during extraction.

• Select correct separator diameter and orient evenly around the part
• Apply steady, incremental torque to the forcing screw
• Use personal protective equipment and support the workpiece securely

Who is this for: The DAYUAN 14-piece bearing separator puller set is aimed at professional mechanics, equipment maintenance technicians, and serious DIYers who work with press-fit bearings, gears, and pulleys. If you need a durable, modular extraction solution that organizes neatly in a case and offers compatibility with standard puller accessories, this kit is a practical choice.
