Product Features
Feature 1: There is a wide range of options for inner and outer diameters and thickness, and for the L dimension configurable type, the thickness can be specified in 0.1mm increments.
Feature 2: High-precision products made by cutting and machining can realize high-precision spatial adjustment. For precision grade products, an L dimension tolerance of ±0.01mm can be guaranteed.
Feature 3: Depending on the design requirements, there are three types of optional materials: general structural steel or carbon steel, alloy tool steel or bearing steel, and SUS420J2.
Feature 4: For products made of general structural steel or carbon steel and alloy tool steel or bearing steel, there are two types of optional surface treatment: ferroferric oxide protective film and electroless nickel plating.

Usage Method
| Diagram | Instructions |
 | It can be used to ensure the relative position between two timing pulleys. |
 | It can be used for limiting the position of the linear parts or fixed parts on the shaft. |
 | Can be matched with screws to control the relative clearance between the sheet metal and the support. |
Precautions
①When D=16 or less, chamfer C is 0.1-0.2.
When D=20 or more, chamfer C is 0.5 or less.
②When the relative humidity of the operating environment is high and certain anti-rust ability is required, please choose products with surface treatment of electroless nickel plating or products made of SUS3 stainless steel.
③When the operating environment requires certain abrasion resistance and hardness for metal collars, give priority to metal washer hardened products.

Example of Use
■Mechanism name
Different fixtures used according to the frequency of process switching.
■Mechanism function
Because of the use of fast-fixing parts and replaceable positioning parts, it can be used as a support fixture for a variety of workpieces.
■Role of metal collar
A metal collar is placed on the fixed surface of the toggle clamp to limit the height of the toggle clamp. For workpieces of different thicknesses, a variety of metal collars of different lengths can be replaced.
