51206712 / 512 067 12 BUSHING INGERSOLL RAND

Premium Replacement Bushing for High-Load Rock Drilling Applications

The 51206712 / 512 067 12 Bushing Ingersoll Rand is a critical wear component designed to support rotating and reciprocating assemblies inside heavy-duty rock drilling and mining equipment manufactured by Ingersoll Rand. This precision-engineered split bushing plays a central role in maintaining shaft alignment, absorbing radial loads, and ensuring smooth motion under extreme operational stress.

In demanding environments such as surface mining, quarrying, tunneling, and large infrastructure projects, even a small deviation in internal tolerances can lead to accelerated wear across the drivetrain. That is exactly why the 51206712 / 512 067 12 Bushing Ingersoll Rand is produced to tight dimensional standards and optimized surface geometry, allowing it to operate reliably under continuous vibration, shock loads, and heavy torque cycles.

At 3GEN Export, we manufacture and supply this component as an OEM-standard replacement part, delivering consistent quality and worldwide shipping in just 5 working days.

What Is the 51206712 / 512 067 12 Bushing Ingersoll Rand?

The 51206712 / 512 067 12 Bushing Ingersoll Rand is a split cylindrical bearing sleeve typically installed inside gear housings, drive assemblies, or rotary sections of rock drilling machines. Its primary function is to:

• Reduce friction between rotating shafts and fixed housings

• Maintain concentric alignment of drive components

• Absorb radial forces generated during drilling operations

• Provide a sacrificial wear surface that protects higher-value components

Unlike rolling bearings, this type of bushing distributes loads evenly over a larger surface area. This makes it ideal for low-speed, high-load applications where shock resistance and durability matter more than rotational speed.

The internal textured pattern visible in the images is not decorative. It is engineered to retain lubrication, allowing oil or grease to remain evenly distributed across the contact surface. This significantly reduces metal-to-metal contact and extends service intervals in harsh environments.

Key Engineering Characteristics

Split Design for Easy Installation

The split construction of the 51206712 / 512 067 12 Bushing Ingersoll Rand allows technicians to install or remove the bushing without fully dismantling surrounding assemblies. This saves valuable maintenance time and minimizes machine downtime on site.

Optimized Lubrication Retention

The inner surface features precision perforations that act as micro-reservoirs for lubricant. This ensures consistent lubrication even under intermittent grease supply or high thermal loads.

High Load-Bearing Capacity

Manufactured from industrial-grade bearing alloy, this bushing is capable of supporting heavy radial forces while maintaining dimensional stability. It performs reliably under:

• Continuous vibration

• Impact loading from drilling cycles

• Elevated operating temperatures

• Dust-rich and abrasive environments

Corrosion and Wear Resistance

The material composition provides excellent resistance to corrosion and surface fatigue, making it suitable for long-term operation in outdoor mining and construction conditions.

Typical Applications

The 51206712 / 512 067 12 Bushing Ingersoll Rand is commonly used in:

• Rock drill drive systems

• Rotary gear assemblies

• Percussion housing sections

• Transmission interfaces

• Auxiliary shaft supports

These applications demand absolute consistency in tolerances, because even minor deviations can lead to gear misalignment, vibration amplification, and premature failure of adjacent parts.

Compatible Ingersoll Rand Equipment (Common Applications)

While exact placement may vary by configuration and serial number, this bushing is widely used across multiple Ingersoll Rand rock drilling and mining platforms, including but not limited to:

YH65, YH70, YH80

• Surface drill rigs

• Crawler-mounted rock drills

• Down-the-hole drilling systems

• Hydraulic rotary drilling units

• Heavy percussion drill assemblies

Why This Bushing Matters in Rock Drilling Systems

Rock drilling equipment operates under some of the most aggressive mechanical conditions found in industrial machinery. Every drilling cycle generates:

• High torsional forces

• Repeated impact loads

• Continuous vibration

• Thermal expansion

The 51206712 / 512 067 12 Bushing Ingersoll Rand acts as a protective interface between moving and stationary parts. By absorbing these stresses, it prevents direct wear on shafts and housings that are far more expensive to replace.

A worn bushing may seem insignificant, but it can quickly lead to:

• Gear misalignment

• Increased noise and vibration

• Accelerated shaft wear

• Oil contamination

• Reduced drilling efficiency

Replacing this component at proper service intervals dramatically improves overall machine reliability and operating lifespan.

At 3GEN Export, we supply this part as an OEM-standard replacement, produced using controlled machining processes and strict dimensional inspections. Each 51206712 / 512 067 12 Bushing Ingersoll Rand is manufactured to match original performance characteristics without using original branding.

Our production focuses on:

• Accurate inner and outer diameters

• Consistent wall thickness

• Uniform lubrication pocket geometry

• Smooth seating surfaces

Every unit is quality-checked before dispatch, ensuring it integrates seamlessly into your existing equipment.

Installation Guidance

Professional installation is recommended. Typical steps include:

1. Clean the housing bore thoroughly

2. Apply assembly lubricant to the bushing outer surface

3. Insert the split bushing evenly into the housing

4. Ensure correct alignment of the split joint

5. Verify shaft clearance before final assembly

After installation, always confirm proper lubrication flow and run the machine at low load initially to allow surfaces to bed in.
