Rösler Gamma blast wheel is one of the most popular centrifugal blast wheels for shot blasting machines, widely used in steel structure, foundry, forging and automotive shot peening. We supply full range of Rösler Gamma blast wheel spare parts for Gamma300G, Gamma400G, Gamma520 and Rutten Gamma long-life carbide blast wheels.

The signature Y-shaped reversible throwing blade of Gamma G is the main wear part. It adopts quick-change design and can be flipped and used on both sides without removing the blade wheel. Besides throwing blades, we stock control cage, impeller, blade wheel, end guard, feed sleeve, bearing housing assembly, main shaft, oil seals, coupling and liner plates.

Rutten Gamma carbide blades share most mounting dimensions with standard Gamma G blades, but feature carbide material for much longer service life. We also provide high-chromium cast iron and forged steel alternative parts as cost-effective replacements for original Rösler Gamma blast wheel parts.

Before ordering Rösler Gamma blast wheel spare parts, please confirm the blast wheel model, motor power, serial number and stamped original part number to avoid mismatch.

Rösler (Germany) is a globally recognized surface treatment brand, mainly featuring Gamma G and Rutten Gamma series turbine shot blasters (blast turbines). Their machines are known for wear resistance, low energy consumption, and customizability. They're widely used in casting, steel structures, forging, automotive, and aerospace for rust removal, oxide scale removal, deburring, and shot peening enhancement.

Main Models

1. Roller conveyor type RRB/RRBK: Continuous cleaning of steel plates, profiles, H-beams, steel pipes; RRBK is suitable for large complex steel structures, multiple heads arranged around for full-surface cleaning in one go.

2. Tumble belt RMBC/RMBD: For small batches, castings, and forgings; rubber/steel tracks optional, suitable for batch shot peening with material flipping.

3. Hook type / Chain type: For large or delicate workpieces, single hook/multi-station, continuous rail hook peening machines (commonly used for spring and gear shot peening).

4. Wire mesh belt, robotic shot blasters, manual blast cabinets: For precision, sensitive workpieces, or small batch blasting.

Features: Shot chambers lined with manganese steel wear plates, standard with shot material air separation, bucket elevator, dust collection system; supports Rösler Smart online monitoring and predictive maintenance.

Core Wear Parts (Most Common)

1. Gamma G / Rutten Gamma Shot Blasters (complete assemblies)

• Y-type double-sided blades (key consumable, usable on both sides, doubling lifespan, quick-change design without dismantling the blaster housing)

• Shot wheels, directional sleeves (control the throwing angle)

• Impeller discs, guard plates, end guard plates, housing wear liners

• Bearing housings, seals, couplings, motors

2. Chamber Wear Parts

• Manganese steel liners, overlapping protection plates, door liners, inlet/outlet wear plates

• Rubber sealing strips, dust curtains, protective rubber panels

3. Shot Material Circulation and Separation System Parts

• Bucket elevators: hoppers, belts/chains, sprockets, shafts

• Screw conveyors: auger blades, shaft, liner

• Air separators (air classifiers): adjustment plates, wear-resistant guide plates

• Magnetic separators, vibrating screens, screen plates (for sand removal in casting)

4. Dust Collection System

• Cartridge filters (explosion-proof / standard dry type), pulse solenoid valves, cylinders, ash discharge air locks

Rösler dust emission can reach <1mg/Nm³.

5. Conveyor Components

• Rubber/steel tracks, roller conveyors, idlers, wire mesh belts, hook rollers, travel wheels

6. Other Accessories

• Wear-resistant ducts, level switches, shot replenishing devices, electrical components, sensors, program modules

Features of Accessories

• Gamma blades are Rösler’s signature parts: Y-shaped curved, double-sided use; compared to standard throwing heads, they improve throwing efficiency by ~20% and reduce energy consumption; Rutten Gamma carbide versions can last up to 12 times longer than normal blades.

• Original parts are highly accurate and provide stable throw patterns; there are also domestic alternatives (manganese steel, high-chrome) with good cost performance.

Common Applications

• Steel Structures: Rust removal of steel plates/profiles, pre-treatment before painting

• Casting: Sand removal, oxide skin removal

• Auto Parts / Springs: Shot peening to improve fatigue strength

• Forging: Oxide and burr removal

Purchasing Tips

When ordering parts, generally needed: machine model, blaster model (Gamma300G/400G, etc.), blade number, original part number; many older machines also support upgrading to Gamma G throw heads.
