MIKI PULLEY
Shaft and mounting parts have a large allowable dimensions tolerance, and can be easily aligned and positioned. Can support heavy loads.
[Features]
· Tightening the clamping bolt moves the 2 taper rings in the shaft direction.
· At this time, the wedging action between both the inner ring and the outer ring against the taper surface produces force that pushes against the shaft and hub internal surface. This force completely connects the axis and shaft.
· The PSL-G has an even transmission ability due to its simple construction and strong components, and it can also cope with heavy loads.
· Short in shaft direction, does not take up more space than necessary.
· PSL-G-C (simple rust-proofing specification) is a simple rust proofing specification that involves applying electroless nickel plating to the main body.From: ฿ 1,813.78 Days to Ship:

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:

Shaft and mounting parts have a large allowable dimensions tolerance, and can be easily aligned and positioned. Medium load and lightweight type.
[Features]
· Tighten the clamping bolt to move the outer ring in the shaft direction.
· At this time, the wedge action on the tapered face with the inner ring creates a force that pushes the shaft and the hub inner face, which forces the shaft and the hub to be fully engaged.
· The PSL-D is designed for medium loading, with a small surface pressure and reduced installation diameter and weight.
· Short in shaft direction, does not take up more space than necessary.
· PSL-D-C is a simple rust proofing specification that involves applying electroless nickel plating to the main body.From: ฿ 2,511.30 Special Price 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.
