Product Features
Feature 1: There is a wide range of options for inner and outer diameters and thickness, which can be specified in 0.5mm increments.
Feature 2: Depending on the design requirements, there are three types of optional materials: general structural steel or carbon steel (equivalent), alloy tool steel or bearing steel, and austenitic stainless steel.
Feature 3: 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
DiagramInstructions
Usage Method of Simultaneous Grinding Straight SpacersIt can be used to ensure the relative position between two timing pulleys.
Usage Method of Simultaneous Grinding Straight SpacersIt can be used for limiting the position of the linear parts or fixed parts on the shaft.
Usage Method of Simultaneous Grinding Straight SpacersCan be matched with screws to control the relative clearance between the sheet metal and the support.
Precautions
①When the relative humidity of the operating environment is high and certain anti-rust ability is required, please choose products with electroless nickel plating surface treatment or stainless steel SUS3 series materials.
②When the operating environment requires certain abrasion resistance and hardness for metal washers, please give priority to metal washer quenched products.
Example of Use
Examples of Using Metal Collars
■Equipment 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.
