MPIZ Flanged Brass Bushing: Precision Self-Lubricating Solutions for Industrial Applications
MPIZ flanged brass bushings deliver reliable performance in mechanical systems, combining high load capacity, self-lubrication, and axial support. Ideal for automotive, industrial machinery, and automation, these bushings reduce friction, minimize maintenance, and extend equipment life. Explore key features, specs, and uses below for quick selection.
What Is an MPIZ Flanged Brass Bushing?
MPIZ flanged brass bushings are cylindrical sleeve bearings with an integrated flange, designed for smooth shaft rotation or sliding. Key components include:
- Cylindrical Body: Fits into housing bores to support radial loads on shafts.
- Integrated Flange: Provides axial positioning, thrust support, and easy installation.
- Brass Alloy Base: High-strength material for durability and corrosion resistance.
- Embedded Solid Lubricant: Graphite plugs for self-lubrication, eliminating external grease needs.

Core Properties and Technical Specifications
MPIZ bushings feature manganese bronze alloys with embedded graphite for superior wear resistance and embeddability. They handle contaminants effectively while maintaining low friction.
| Specification | Value/Range | Unit | Key Benefit |
|---|---|---|---|
| Type | Flange Integrated | – | Combines radial and axial support in one piece. |
| Material | Brass Alloy with Graphite | – | Self-lubricating; resists abrasion and corrosion. |
| Inner Diameter (I.D.) | 8–50 | mm | Matches shaft sizes for precise fit. |
| Outer Diameter (O.D.) | 12–62 | mm | Fits standard housing bores (h7 tolerance). |
| Overall Length (L) | 20–100 | mm | Customizable for application depth. |
| Max PV Value | 1.1–2.0 (Typical 1.65) | N/mm²·m/s | Balances high loads and speeds without failure. |
| Max Static Load | 29 | N/mm² | Withstands stationary pressure without deformation. |
| Max Velocity | 0.5 | m/s | Supports moderate-speed operations reliably. |
| Temperature Range | -40 to +150 | °C | Versatile for cold to hot environments. |
| RoHS Compliance | Yes | – | Meets environmental safety standards. |
PV Value Insight: Measures pressure (load) × velocity (speed). Higher values indicate better performance under combined stress—embedded lubricant boosts this for extended service.
Applications: Targeted Use Cases
MPIZ bushings excel in self-lubricating, space-constrained setups with radial/axial loads. Common placements:
- Linear Motion Systems:
- Guide blocks in rails: Supports sliding shafts in CNC machines and automation lines; flange secures position, saving assembly time.
- Valve and Rod Guides:
- Valve stem housings: Provides corrosion-resistant support for reciprocating motion; ideal for pumps and hydraulics.
- Conveyor and Packaging Equipment:
- Roller axle mounts: Handles continuous sliding in food/chemical settings; no oil prevents contamination.
- Robotics and Pivots:
- Joint linkages: Balances shock loads in arms and presses; embedded design fits tight spaces.
- Vertical Supports:
- Pillar guides in lifts: Optimizes height with flush flange; suits agricultural and construction gear.
Installation Tip: Secure with 2–4 socket head cap screws (M3–M10) via flange holes; pair with d8 shaft tolerance for heavy loads.
Advantages: Comparison with Alternatives
MPIZ bushings offer balanced performance for mid-load, self-lubricating needs. See how they compare:
| Feature | MPIZ Flanged Brass (Self-Lube) | Plain Brass Bushing | Polymer Bushing (e.g., Nylon) | Rolling Element Bearing |
|---|---|---|---|---|
| Lubrication | Self (Embedded Graphite) | Requires Grease | Often Self/Dry | Requires Grease (Sealed) |
| Load Capacity | High | High | Low–Medium | Very High |
| Speed Capability | Moderate (up to 0.5 m/s) | Moderate | Low–High | High–Very High |
| PV Limit | Good–High | Moderate | Low–Moderate | N/A |
| Temperature Range | Wide (-40 to +150°C) | Wide | Limited | Wide |
| Shock Tolerance | Excellent | Excellent | Good | Poor–Fair |
| Contamination Resistance | Good (Embeddable) | Fair | Good–Excellent | Poor |
| Corrosion Resistance | Good | Good | Excellent | Fair–Good |
| Noise Level | Low | Low | Very Low | Low |
| Initial Cost | Moderate | Low–Moderate | Low | Moderate–High |
| Total Cost of Ownership | Low (Minimal Maintenance) | Moderate | Low–Moderate | Moderate–High |
| Flange Option | Standard | Available | Available | Available |
Quick Insights:
- Choose MPIZ for shock-heavy, dirty environments over polymers.
- Lower maintenance than plain brass; more compact than rolling bearings.
Installation and Maintenance Guidelines
Installation Steps:
- Clean shaft and bore; remove burrs.
- Use arbor press for even force—avoid hammering.
- Ensure interference fit (O.D. slightly larger); ream I.D. if needed post-install.
- Seat flange flush for thrust applications.
Maintenance Tips:
- Inspect periodically for wear or play.
- Wipe debris in dusty areas—self-lube handles most contaminants.
- Operate within PV/speed/temp limits to maximize life.
Sustainability Benefits
- Recyclable Material: Brass alloys reduce resource use.
- No External Lubricants: Cuts oil/grease waste and leaks.
- Energy Savings: Low friction lowers system power draw.
- Longer Life: Fewer replacements mean less manufacturing waste.
