Threaded Ball Knob uxcell M8x40mm Black Phenolic Copper Insert

Description

Product Overview

The uxcell threaded ball knobs are engineered for industrial applications where reliability and precision matter. Each knob measures 40mm in diameter and features a standard M8 female thread, allowing seamless integration with a wide range of machine lever handles. Constructed from high‑impact phenolic resin, the body resists heat, chemicals, and mechanical wear, while the embedded copper thread insert ensures a strong, corrosion‑resistant connection that will not strip under repeated use. The black finish provides a neutral aesthetic that blends into most control panels, and the smooth, rounded surface delivers a comfortable grip for operators who need to make frequent adjustments. With a pack of two knobs, users can replace worn components quickly, minimizing downtime and maintaining consistent performance across equipment.

Usage

These ball knobs are ideal for a variety of machinery, including CNC routers, lathes, drill presses, textile equipment, and woodworking tools. Their robust construction makes them suitable for harsh environments such as metalworking shops, where exposure to oil, coolant, and temperature fluctuations is common. The easy‑thread design allows technicians to install or replace the knobs without special tools—simply align the female thread with the lever shaft and turn clockwise until snug. Because the knobs are sized to standard M8 threads, they fit a broad spectrum of existing hardware, reducing the need for custom adapters. Operators benefit from the ergonomic shape, which reduces hand fatigue during prolonged adjustments, and the non‑slip surface ensures precise control over machine settings, whether fine‑tuning a gear ratio or setting a valve position.

FAQ

What material is the ball knob made from and why is it beneficial?

The knob body is made from phenolic resin, a material known for its high impact resistance, heat tolerance, and electrical insulating properties. This combination ensures the knob can withstand the rigors of industrial use while protecting operators from accidental electrical contact.

Can I install the knob without special tools?

Yes. The threaded design allows the knob to be screwed directly onto a compatible lever shaft. Align the female thread with the shaft, turn clockwise until it is firmly seated, and no additional tools are required.

What sizes are available and how do I choose the right one?

uxcell offers a range of sizes from M5 to M12. To select the correct size, measure the diameter of the existing lever shaft and match it to the corresponding thread designation (e.g., M8 for an 8 mm shaft). The product listing provides the full size matrix for reference.

Is the black finish purely cosmetic or does it serve a functional purpose?

The black coating helps conceal wear and staining that can occur in industrial environments, extending the visual life of the knob. It also reduces glare, making it easier for operators to see the knob’s position and markings during use.

What warranty or support does uxcell provide for these knobs?

uxcell offers a standard one‑year warranty covering manufacturing defects. In addition, the company’s customer support team is available to assist with installation guidance, part compatibility questions, and any return or exchange processes needed.
