15367138, 153 671 38 REAR CYLINDER SANDVIK

When rock drilling productivity matters, the stability of the drifter’s rear-end assembly becomes a make-or-break detail. The 15367138, 153 671 38 REAR CYLINDER SANDVIK is designed to support the rear section of the rock drill/drifter cylinder group, helping the percussion system stay aligned under continuous impact loads, high hydraulic pressures, and harsh site conditions.

Built as a precision-machined cylindrical component, the 15367138, 153 671 38 REAR CYLINDER SANDVIK is manufactured to keep sealing surfaces consistent, maintain internal flow paths, and protect critical moving parts from misalignment and premature wear. If your operation involves repetitive drilling cycles in abrasive rock, this is the kind of component that quietly decides whether the drifter runs smooth for months—or starts bleeding performance week by week.

At 3GEN Export, we supply this part as an OEM-standard manufactured component and deliver worldwide in 5 working days, helping you keep drilling schedules on track without long downtime windows.

What the 15367138 Rear Cylinder Does in a Rock Drill System

The 15367138, 153 671 38 REAR CYLINDER SANDVIK is positioned at the rear side of the drifter cylinder assembly. In many drifter architectures, the rear cylinder area is where alignment, sealing, and oil routing all converge. That means the component must do multiple jobs at once:

• Provide a rigid housing surface that resists deformation under percussion forces

• Maintain internal cylindrical geometry so mating parts run true

• Support seal grooves and sealing lands for hydraulic tightness

• Manage oil movement through drilled ports and channels (as seen on the part’s body)

• Contribute to overall drifter balance by holding tolerances in the rear-end assembly

Because the rear cylinder is exposed to repeated impact energy and vibration, any tolerance drift, poor surface finish, or uneven hardness can show up as leakage, heat build-up, unstable drilling speed, and abnormal wear patterns.

Visual & Build Details Seen in the Part

From the product images, the 15367138, 153 671 38 REAR CYLINDER SANDVIK shows several functional machining characteristics typical of high-load hydraulic/percussion components:

External ring grooves (circumferential lines)

These grooves commonly serve one or more of the following purposes:

• Seating/retention interfaces for adjacent components

• Reference surfaces for assembly alignment

• Controlled fit zones that reduce micro-movement under vibration

Radial drilled ports (multiple holes around the body)

The visible drilled holes typically indicate oil routing, pressure balancing, or controlled lubrication flow between internal passages and adjacent chambers. On percussion equipment, these features help stabilize performance across different drilling angles and duty cycles.

Precision internal bore with visible longitudinal texture

The internal surface appears consistent and straight, suggesting controlled machining for a tight fit with mating internal elements. In practice, this contributes to:

• Stable sealing behavior

• Reduced internal scoring risk

• Better hydraulic efficiency over time

Note on verification

Different rigs can share drifter families, but fitment can vary by serial range, configuration, or retrofit kit. If you want, share your rig model and drifter/serial info and I’ll format a compatibility confirmation checklist for your team.

Why the 15367138 Rear Cylinder Matters for Drilling Performance

A drifter is unforgiving. Small deviations become big losses because the machine repeats the same cycle thousands of times per shift. The 15367138, 153 671 38 REAR CYLINDER SANDVIK directly influences:

Drilling consistency

Stable rear-cylinder geometry helps maintain a steady percussion cycle. When the rear-end assembly runs true, the energy transfer stays more predictable.

Hydraulic efficiency

Rear cylinder sealing zones and ports influence pressure stability. If clearances drift, pressure losses and heat rise.

Component life around the rear section

Rear bushings, seal kits, mating sleeves, and internal moving members all benefit from tight alignment. A rear cylinder that holds tolerance reduces uneven wear.

Downtime prevention

Rear-end leakage or abnormal wear often triggers unplanned shutdowns. Replacing a rear cylinder at the right time can prevent a larger rebuild.

Technical Specifications (Typical, OEM-Standard Manufacturing)

Exact specifications can vary by machine configuration, but a high-quality 15367138, 153 671 38 REAR CYLINDER SANDVIK is commonly produced to meet expectations like these:

Material & metallurgy

• High-strength alloy steel suitable for percussion/hydraulic service

• Controlled heat treatment for a balanced hardness/toughness profile

• Resistance to impact fatigue and micro-cracking under vibration

Machining & tolerance control

• Precision-turned and bored surfaces for stable roundness

• Controlled concentricity between outer body and internal bore

• Cleanly finished seal lands to reduce leakage risk

Surface finish expectations

• Smooth functional surfaces to protect seals

• Stable bore finish to reduce scoring and premature wear

Port and passage integrity

• Deburred drilled holes and passage edges

• Clean internal routing to reduce contamination traps

Estimated Weight (KG)

For the 15367138, 153 671 38 REAR CYLINDER SANDVIK, a realistic operational estimate is:

• Estimated weight: ~14 kg

This is an estimate based on the part’s geometry and typical steel construction for drifter cylinder components. If you share exact dimensions or shipping carton data, I can refine it to a tighter number.

Installation Guidance for the Rear Cylinder (Practical Field Steps)

Below is a field-friendly approach for replacing the 15367138, 153 671 38 REAR CYLINDER SANDVIK. Always follow your rig’s service procedure, but these steps reflect best practice for precision parts.

1) Preparation

• Clean the drifter exterior before disassembly to reduce contamination entry

• Mark relative positions if your assembly uses indexed alignment

• Prepare new seals, O-rings, and wear items recommended for the rear-end service

2) Safe disassembly

• Depressurize the hydraulic system completely

• Drain oil from the relevant section where required

• Use correct lifting support: cylinder components are heavy and can chip on impact

3) Inspection before installing the new rear cylinder

Check mating components for:

• Scoring, ovality, or discoloration from overheating

• Seal groove damage on adjacent parts

• Abnormal wear patterns that indicate misalignment

If the old unit failed due to contamination, do not install the new 15367138, 153 671 38 REAR CYLINDER SANDVIKwithout addressing filtration and cleaning—otherwise the new part may inherit the same failure mode.

4) Installation & alignment

• Lubricate sealing surfaces with compatible clean hydraulic oil

• Install seals carefully without twisting or nicking

• Confirm port orientations align with the assembly’s oil routing paths

• Tighten to specified torque values (from your service manual)

5) Commissioning checks

• Run at low load first and monitor leakage

• Watch operating temperature trends

• Verify drilling response remains stable across several cycles

Maintenance Tips to Extend Service Life

To keep the 15367138, 153 671 38 REAR CYLINDER SANDVIK running longer in real drilling conditions:

Keep oil cleanliness high

Contaminants cause bore scoring and seal damage. Clean oil is the cheapest performance upgrade you can buy.

Monitor early warning signs

• Slow pressure build-up

• Temperature rise at the drifter

• New seepage around rear-end joints

• Unusual vibration increase

Replace wear items as a set when needed

A rear cylinder can be forced to “carry” failures from worn bushings or tired seals. Servicing the assembly as a system often reduces total cost over time.

Common Failure Symptoms and What They Mean

Oil leakage near rear-end assembly

Often indicates seal wear, surface scoring, or loss of sealing land integrity.

Reduced impact efficiency

Can be caused by internal pressure losses or misalignment impacting the percussion cycle.

Rapid seal failures

Usually linked to contamination, overheating, or surface finish issues on the cylinder/seal interfaces.

When a rear cylinder is replaced with an OEM-standard manufactured component like the 15367138, 153 671 38 REAR CYLINDER SANDVIK from 3GEN Export, the most important outcome is restoring stability—so the drifter’s energy goes into rock, not into heat and vibration.
