Flanged Bronze Sleeve Bearings with Split Design and Grooved Lubrication Channels

Flanged Bronze Sleeve Bearings with Split Design and Grooved Lubrication Channels

When it comes to high-performance machinery, flanged bronze sleeve bearings with a split design offer unmatched convenience and durability. Unlike traditional hollow-section bearings that rely on oil pockets, these advanced bushes use grooved races for superior lubrication.

Key Features and Advantages:

• Flanged Design: The flange ensures precise axial positioning, prevents shaft movement, and simplifies installation, especially in heavy-duty applications.

• Split Construction: Split bushes are easy to install and replace without disassembling shafts or machinery, saving time and reducing downtime.

• Grooved Lubrication Channels: Instead of hollow sections, grooves distribute lubricant evenly along the shaft surface, providing continuous lubrication and preventing wear or dry spots.

• Enhanced Performance: Grooved races increase load capacity and reliability, particularly in oscillating or high-speed applications.

• Durable Bronze Material: Perfect for industrial equipment such as cranes, presses, and other heavy machinery, where consistent lubrication and long service life are critical.

Why Choose Grooved Split Bronze Bushings?
Grooved lubrication channels eliminate the risk of oil starvation common in hollow-section designs. They also make maintenance easier and improve bearing performance under heavy load and oscillating conditions. The combination of flange, split construction, and grooved races ensures your machinery runs smoother, lasts longer, and requires less maintenance.

Upgrade your industrial equipment with flanged bronze sleeve bearings with split design and grooved lubrication channels—engineered for reliability, efficiency, and long-term performance.

Grooved Race-Type Flanged Bronze Sleeve Split Bushings

The “grooved race-type” design in flanged bronze sleeve split bushings refers to a specialized lubrication groove pattern machined directly into the inner surface (bore) of the bearing. These grooves create a continuous lubrication race—a pathway that allows oil or grease to flow evenly, forming a reliable lubricant film between the shaft and the bushing.

This design significantly enhances performance under heavy loads, oscillating or rotating motion, and infrequent maintenance conditions, making it ideal for construction equipment, excavators, crushers, gearboxes, and other heavy machinery.

Common “Race Type” Groove Patterns

The term “race type” describes groove patterns that act like a continuous raceway to distribute lubricant, prevent dry spots, and minimize metal-to-metal contact. The most common patterns used in bronze bushings (especially cast C93200/SAE 660 or wrapped CuSn8 types) include:

1. Spiral (Helical) Grooves

• A continuous helical channel winding along the bore.

• Ideal for rotational motion and high-speed applications.

• Creates a pumping effect that spreads lubricant evenly and helps with heat dissipation.

• Often used in flanged or split-compatible bronze bushings.

2. Figure-8 (Double Loop / ∞) Grooves

• Overlapping loops forming a figure-8 pattern.

• Perfect for bidirectional or oscillating motion.

• Distributes grease or oil across the full surface and performs well under reversing loads.

• Frequently preferred in grease-lubricated applications.

3. Other Related Groove Patterns

• Straight axial grooves: for linear or oscillating motion.

• Circular/annular grooves: for pressure-fed lubrication.

• Diamond or combined patterns: for heavy-duty debris management.

Grooves can also be custom-machined—V-shaped or optimized for better flow. In split or flanged bushings, grooves are usually positioned away from the split line to maintain structural integrity.

Why “Race Type” Matters

The grooved race design:

• Retains lubricant longer, extending maintenance intervals.

• Promotes hydrodynamic lubrication, forming a stable oil film.

• Reduces friction, wear, and heat buildup.

• Increases PV capacity (Pressure × Velocity), allowing the bearing to handle higher loads.

For split flanged bronze bushings, this design combines easy installation around shafts with robust, maintenance-efficient performance, making it a preferred choice in heavy-duty industrial applications.
