Until 31/03/2025MIKI PULLEY
Easy to attach or detach with 1 bolt reducing the mounting time by 90%.
[Features]
· Due to a completely integrated structure, the hub is mountable at a concentricity of several μm.
· Can be easily and quickly mounted and removed with just 1 pressure screw.
· Pressure screw has a structure that mounts from a radial direction and does not take up mounting-operation space.
· Eliminates trouble caused by keys, such as keyway machining, etc.
· Further, the shaft and hub have general machining tolerance and require no special finishing.
· Only radial loads work on the shaft and hub, no thrust load is applied.
· Fastening is simple as only 1 bolt is to be tightened.
· Ideal where accuracy is required because the product has excellent concentricity of 0.006 mmFrom: ฿ 8,432.24 Special Price Days to Ship:

MIKI PULLEY
Simple and high-accuracy frictional joint fitting using the principle of Pascal.
[Features]
· The coupling between the shaft and the hub is realized by a hydro method using the principle of Pascal, and the shortcomings and difficulties caused by key connection are solved at once.
· The machining tolerance between the shaft and the hub is a general fit tolerance, and no special finishing is required. Positioning in both rotational and axial directions can be performed freely.
· Furthermore, the unique bolting of 1 hydro method greatly reduces the number of work steps.
· Because the concentricity is excellent at 0.02 mm, it is ideal for places where high-accuracy is required and the frequency of attachment and detachment is high.
· Operating space is not required because the structure is tightened from the radial direction.
[Applications]
· Used in machine tools, pumps, molding machines, printing machines, palletizing robots, various jigs and tools.From: ฿ 5,089.75 Days to Ship:

FAQ Keyless Bushing (Fastening Fittings)
- Question: What is a Keyless Bushing and how does it work?
- Answer: A Keyless Bushing is a mechanical component used for fastening fittings, providing a secure connection between shafts and hubs without the need for traditional keys. It utilizes frictional forces to securely grip the shaft and hub, ensuring a backlash-free fit.
- Question: What are the benefits of using Keyless Bushings?
- Answer: Keyless Bushings offer several advantages, including simplified installation without the need for keyways, reduced maintenance time and costs, and enhanced reliability due to their secure locking mechanisms. They also provide precise and backlash-free shaft-to-hub connections.
- Question: How do I install a Keyless Bushing?
- Answer: Installing a Keyless Bushing is straightforward. Simply slide the bushing onto the shaft and tighten the locking screws to achieve a secure grip between the shaft and the hub. Detailed installation instructions can be found in the product manual.
- Question: Can Keyless Bushings be used in high-speed applications?
- Answer: Yes, Keyless Bushings are suitable for use in high-speed applications. They are engineered to provide secure and reliable shaft-to-hub connections even under high rotational speeds, ensuring smooth operation and minimal vibration.
- Question: What materials are Keyless Bushings made of?
- Answer: Keyless Bushings are typically made from high-quality materials such as stainless steel, carbon steel, or alloy steel. These materials offer excellent strength, durability, and corrosion resistance, ensuring long-term performance in various environments.
- Question: Are Keyless Bushings reusable?
- Answer: Yes, Keyless Bushings are reusable components. They can be easily removed from one application and installed in another, making them a cost-effective solution for multiple shaft-to-hub connections.
- Question: Do Keyless Bushings require lubrication?
- Answer: Keyless Bushings typically do not require lubrication for normal operation. However, applying a small amount of lubricant to the shaft before installation can help facilitate easier assembly and removal.
