Precision Forged Collar

Precision forged collar is a circular cylindrical fastener, using closed die precision forging, press hot metal blank and form the desired shape.
Core functions of collar are shaft end locking, bearing fixation, axial limit, and uniform load distribution.
Forged collar can eliminate defects like air holes, cracks, and porosity from the root.

Compared with other collars that are produced by CNC machining, casting or stamping, forged collar has excellent performance advantage, is highly competitive for industrial purchasers:

• Maximum Mechanical Strength: Shata Machinery adopts closed die precision forging, refining metal grain, forming continuous flow line, their tensile strength, impact resistance and fatigue life is about 20%~30% higher than CNC machined collar
• Ultra-High Dimensional Accuracy: we strictly control forging tolerance, our precision forging can meet 0.1~0.2mm tolerance, no need to be machined for unimportant surfaces, ensuring perfect compatibility for high-precision assembly.
• Good Material Utilization Rate: thanks to the high forging accuracy, our collars have less machining surfaces, greatly reduced material waste and lower the unit price, especially ideal for large-scale production.
• Durable & Corrosion Resistant: Dense metal structure with high-quality raw materials, help collar get improved wear resistance and corrosion resistance, perfect meet requirements of outdoor, marine, offshore, chemical environment.
• High Customization Flexibility: Shata Machinery has nearly twenty years of non-standard customization in castings and forgings. We can produce any collar you designed, or you keep in hand.
• Meanwhile, we provide multiple surface treatment and heat treatment, such as blackening, zinc plating, passivation, quenching, tempering, normalizing, nitriding, etc.

Choosing correct material can obviously improve performance and service life of collar.
Shata Machinery strictly selects industrial grade steel, supports various material customization.

1. Carbon Steel (1045, C45, 45#)
If your collar is used for light load, basic fastening, these materials are the most cost-effective one.

2. Alloy Steel (40Cr, 20CrMnTi, 42CrMo)
These are main materials for heavy-duty collars used for heavy load equipment, including engineering machinery, transmission systems.

3. Stainless Steel (304, 304L, 316, 316L, 201, 410, 310S)
For usage of marine, food processing, chemical, outdoor, etc. Excellent corrosion resistance and anti-rust performance. Especially the top-tire corrosion resistant stainless steel 316L collar, is indispensable to ship, offshore wind power and offshore equipment.
Forged 310S collar is a heat-resistant collar used for equipment that works in high temperatures.
