Engineering Precision: VIIPLUS Bronze Gleitlager & Sliding Bearings for Optimal Performance
Mastering Load, Motion, and Durability in Industrial Applications

In the realm of heavy machinery and hydraulic systems, Bronze Gleitlager (sliding bearings) are indispensable for reducing friction, managing extreme loads, and ensuring seamless motion. VIIPLUS, a leader in custom-engineered sliding bearings, offers tailored solutions that combine material science, precision manufacturing, and technical expertise. This article delves into the technical nuances of selecting, installing, and optimizing Bronze Gleitlager, supported by charts, tables, and real-world applications.


Why Bronze Gleitlager? The VIIPLUS Advantage

Bronze sliding bearings are prized for their durability, thermal stability, and self-lubricating properties. VIIPLUS enhances these traits with:

  • Custom material blends for specific load, speed, and environmental conditions.

  • Advanced geometries (cylindrical, flanged, thrust washers).

  • Technical support for installation and lifecycle optimization.


Material Selection: Matching Bearings to Operational Demands

VIIPLUS offers a range of bronze composites tailored to unique industrial challenges. Key factors include:

  1. Load capacity (static/dynamic).

  2. Operating speed (rotary, oscillating, linear).

  3. Environmental conditions (temperature, corrosion, contamination).

Table 1: VIIPLUS Bronze Gleitlager Material Properties

Material Code Load Capacity (N/mm²) Max Speed (m/s) Temperature Range (°C) Best For
BG-200 50 2.5 -50 to +200 High-load hydraulic pumps
BG-300 80 1.8 -30 to +250 Heavy-duty construction gear
BG-400 120 1.2 -20 to +300 High-temperature compressors

 


Installation Guidelines: Ensuring Peak Performance

Proper installation maximizes bearing lifespan and efficiency. VIIPLUS recommends:

1. Straight Sleeve Bushings

  • Use a press-fit arbor 0.1–0.3 mm smaller than the target diameter.

  • Avoid hammering; use thermal expansion for diameters >55 mm.

2. Flanged Bushings

  • Ensure housing chamfers accommodate flange radii.

  • Use arbors with slightly larger diameters for flange alignment.

3. Thrust Washers & Gliding Plates

  • Fix with dowels or countersunk screws.

  • Maintain a sliding layer thickness of 0.3–0.5 mm.


Shaft & Housing Requirements: Precision Pairing

A. Shaft Specifications

  • Surface Roughness:

    • Fluid lubrication: Mirror finish (Ra ≤ 0.2 µm).

    • Dry friction: Ra = 0.4–0.63 µm.

  • Hardness: ≥220 HB. For corrosive environments (e.g., marine), use hard chromium plating (HRC50).

B. Housing Design

  • Chamfering: Match seat holes to VIIPLUS specifications (see Table 2).

  • Tolerance: H7 standard for bore diameter.

Table 2: Housing Chamfer Guidelines

Hole Diameter (mm) Chamfer (mm × Angle)
<30 0.8±0.3 × 20°±5°
30–80 1.2±0.4 × 20°±5°
80–180 1.8±0.8 × 20°±5°
>180 2.5±1.0 × 20°±5°

Applications: Where VIIPLUS Bronze Gleitlager Shine

  1. Hydraulic Pumps (Vane/Plunger/Gear):

    • Self-lubricating bearings reduce maintenance in high-pressure systems.

  2. Marine Propulsion Systems:

    • Corrosion-resistant composites withstand seawater exposure.

  3. Construction Machinery (Excavators, Cranes):

    • High-load bushings handle dynamic shocks and vibrations.

  4. Industrial Compressors:

    • Thermally stable materials prevent deformation under heat.
