M12 Steel Spacer Sleeve Bushings by Minho – 13pcs, 1/2″ ID x 3/4″ OD

Description

Product Overview

The Minho M12 steel spacer sleeve bushings are engineered to meet the rigorous demands of modern industrial equipment. Constructed from high‑grade alloy steel, each bushing combines exceptional strength with superior thermal conductivity, allowing it to dissipate heat generated during heavy‑duty operation. The kit includes thirteen precision‑machined sleeves ranging from 5 mm to 35 mm in length, providing a versatile solution for a wide array of axle and shaft applications.

Designed with an internal M12 thread and a lock‑type fastener style, these bushings secure firmly in place, reducing the risk of loosening under vibration or load shifts. The 1/2″ ID and 3/4″ OD dimensions ensure a snug fit for standard 12 mm classic axles, while the silver‑colored finish offers corrosion resistance for extended service life. Each component is stamped with the Minho part number MH‑BUSH‑001 for easy identification and inventory management.

Beyond mechanical performance, the Minho bushings are tested to meet ISO metric standards for coarse thread class, guaranteeing compatibility with a broad range of hardware and fasteners. The lightweight design—each bushing weighs approximately 0.45 kg—facilitates handling and installation without sacrificing durability. Whether used in manufacturing lines, heavy equipment, or custom‑built machinery, these spacers deliver consistent alignment and load distribution.

Usage

These spacer sleeve bushings excel in environments where precise shaft alignment and vibration mitigation are critical. Typical use cases include hydraulic pump shafts, conveyor motor assemblies, and robotic arm joints where axial movement must be controlled without compromising structural integrity. The range of lengths allows technicians to select the exact spacer needed to bridge gaps, compensate for wear, or adjust positioning during routine maintenance.

Installation is straightforward: insert the bushing onto the shaft, align the M12 thread with the corresponding nut, and tighten to the recommended torque. The lock‑type design ensures the assembly remains secure even under fluctuating loads, making it ideal for applications such as agricultural machinery, construction equipment, and industrial automation where downtime must be minimized.

FAQ

What axle sizes are compatible with these bushings?

The bushings are designed for 12 mm classic axles with a 1/2″ inner diameter and 3/4″ outer diameter, matching standard M12 thread specifications.

How do I determine the correct length for my application?

Measure the gap between the shaft and the mating component, then select the bushing length that best fills that space without causing interference. The kit’s range from 5 mm to 35 mm provides ample options for most scenarios.

Can these bushings be used in high‑temperature environments?

Yes. The alloy steel material offers excellent thermal conductivity, allowing the bushing to dissipate heat effectively and maintain dimensional stability even under elevated temperatures.

Is the lock‑type thread compatible with standard M12 nuts?

Absolutely. The internal M12 lock thread is engineered to work with standard M12 nuts and washers, providing a secure, vibration‑resistant connection.

What warranty does Minho provide?

Minho offers a one‑year limited warranty covering material defects and workmanship. Should any issue arise within this period, contact our support team for a replacement or repair solution.
