Pangborn, USA (Pangborn, a century-old brand, founded in 1904)
Key distinction: Pangborn from the USA ≠ Pangborn from Qingdao. They are completely different companies, with different parts and different structures, dimensions, and numbering systems for shot blasters.
Pangborn is a globally established manufacturer of high-end shot blasting equipment, specializing in heavy-duty industrial shot blasting cleaning and shot peening strengthening equipment. It is famous for its self-developed RK series shot blasters (the 180-3RK and 180-4RK are the most classic), mainly used in casting, automotive, aviation, heavy industry, steel structure, wind power, and aluminum alloy precision parts cleaning and strengthening. It is not primarily focused on road shot blasting machines (road models are not its main line).
Mainstream model series
1. Trolley / rotary table shot blasting machine Heavy-duty castings, molds, large gears, hubs, heavy loads, heavy workpieces, many used in wind power and mining parts.
2. Hook-type shot blasting machine (Hanger / Overhead Monorail): single-hook, double-hook, chain-through type, welded structural parts, frame, valve body, construction machinery, continuous cleaning on the assembly line.
3. Crawler-type Batch Tumblasting Machine for small and medium-sized castings, forgings, and hardware deoxidizing scale, sand cleaning, and deburring.
4. Roller Conveyor Pretreatment Line (Roller Conveyor) for steel plates, profiles, H-beams, steel plate lines, steel structure factories, and can be equipped with painting and drying lines.
5. Specialized shot peening strengthening equipment (Shot Peening) for aerospace, gear, spring, and connecting rod fatigue strength, with high requirements for almen. Pangborn is a strong suit.
6. Air Blast Cabinets for precision small parts, molds, and repair sandblasting.
Core shot blaster model
180-3RK and 180-4RK (the largest market share, with the most domestic second-hand and old equipment), as well as the LE series;
Features: Original high-chrome wear-resistant parts, high dynamic balance requirements, strict precision for parts, even a slight mistake causes significant vibration and easily damages the housing.

Industry Characteristics & Procurement Reminders
1. Most domestic products are early imported second-hand devices and existing old equipment, with very little new models in stock; Original parts have long ordering cycles and high prices, with many users using domestic substitutions
2. When buying accessories, you must provide: shot blaster model (180-4RK? 3RK？ ) + original part number + steering (CW clockwise / CCW counterclockwise); the left and right rotor impellers and blades of the same model are not interchangeable
3. Pangborn, USA, almost no walk-behind shot blasting machines for road surfaces; Shot blasting is Qingdao Panbang's specialty, which is the most confusing area
4. Supports complete machine overhauls and shot blaster refurbishment (Wheel Rebuild), which is also Pangborn's traditional business
Applicable industries
Aerospace, automotive parts (gears, crankshafts, spring shot peening strengthening), casting, wind power, mining equipment, pressure vessels, steel structures, aluminum alloy die-cast parts
Pangborn Model 180-4RK Complete Parts List & Part Number Cross Reference
Important Notes: Pangborn 180-4RK has CW (Clockwise) and CCW (Counterclockwise) rotations. Vanes, impeller wheels and impeller cages are NOT interchangeable between rotations. A standard unit uses 8 vanes. Most original part numbers start with 6-xxxxxx.
1. Core Information (Mandatory for Purchasing)
· Model: 180-4RK (18 inch, 8-vane RK curved blast wheel)
· Rotation: CW = Clockwise (viewed from top); CCW = Counterclockwise; Parts are rotation-specific and cannot be swapped
· Original overhaul kit part number: 6-610648 (CW clockwise assembly kit)
2. Original OEM Part Number Table for 180-4RK Blast Wheel Body (High-Wear Consumables)
1) Rotating Assembly (Core moving components, usually replaced as a set)
2) Housing Wear Liners (Cabinet Wear Parts)
3) Main Shaft & Bearing Assembly
4) Overhaul Tune-Up Kit (CW clockwise complete wear part set)
· Kit Part No.: 6-610648
· Contents: 8 vanes + impeller cage + control cage + full set of liners + sealing parts (complete blast wheel consumables)
3. Abrasive Circulation System Matching Parts for 180-4RK Blast Machine
4. Dust Collection System Parts
5. Critical Purchasing Reminders
1. Confirm rotation first: View the blast wheel shaft from the top. Clockwise = CW (Kit No. 6-610648). CCW vanes and impeller wheels must match rotation; incorrect installation causes severe vibration and broken vanes.
2. Domestic replacement parts: Order by OEM part number + overall dimension + dovetail groove profile. RK vanes adopt self-locking dovetail structure; straight groove vanes cannot be used as substitutes.
3. Dynamic balancing: 8 vanes must be replaced as a matched weight set, otherwise excessive shaft runout will occur.
4. Important distinction: Pangborn USA 180-4RK parts are NOT compatible with parts for Qingdao Panbang road shot blast machines.
