Sliding Bearings and Bushings for Hydraulic Cylinders
Hydraulic cylinders are essential components in industrial machinery, construction equipment, and automation systems. To ensure smooth operation, reduce friction, and handle heavy loads under pressure, these cylinders rely on high-quality bearings and bushings. Typically, bearings and bushings are installed in piston rods, cylinder heads, and mounting points, supporting linear motion while minimizing wear.
Common types used in hydraulic cylinders include wrapped bronze bearings, inlaid solid self-lubricating bearings, and general self-lubricating bearings. They are compatible with double-acting, single-acting, plunger, and specialized hydraulic cylinders, available in both metric and inch sizes, with variations in sealing, dimensions, and width to suit different cylinder designs.
Selecting the right type—whether wrapped bronze, inlaid solid self-lubricating, or general self-lubricating—depends on load, speed, environment, and maintenance preferences. Working with ISO-compliant manufacturers ensures reliability, extended service life, and optimal system efficiency.

Key Advantages for Oilless bearings bushings
All reputable bearings in this category comply with ISO standards, such as ISO 3547 for plain bearings, which ensures dimensional accuracy, material quality, and performance reliability. Self-lubricating bearings eliminate the need for frequent maintenance, while lubricated variants may require periodic oil or grease application for optimal longevity.
Key Types of Sliding Bearings for Hydraulic Cylinders
1. Wrapped Bronze Bearings
Wrapped bronze bearings are made from cold-formed bronze strips (often CuSn8 or CuSn6.5 alloys) with indentations or perforations for lubricant retention.
Advantages:
-
Excellent wear resistance
-
Handles high loads in oscillating or linear movements
-
Cost-effective and corrosion-resistant
-
Suitable for medium-speed applications
Common applications: Hydraulic cylinder bushings where occasional lubrication is possible.
2. Inlaid Solid Self-Lubricating Bearings
These bearings feature a metal base (bronze or steel) embedded with solid lubricants like graphite or MoS2. The inlaid design ensures consistent lubrication even in dry conditions.
Advantages:
-
Maintenance-free operation
-
High load capacity
-
Effective in environments with dirt or contaminants
Common applications: High-pressure hydraulic systems where external lubrication is impractical.
3. Self-Lubricating Bearings
This broader category includes composite materials, such as PTFE-lined steel, polymer composites, or bronze with embedded lubricants.
Advantages:
-
Low friction without oil
-
Extended service life
-
Ideal for clean or sealed systems
-
Environmentally friendly by avoiding oil leaks
Common applications: Industrial hydraulic cylinders used in automation, construction, or marine equipment.
Factors to Consider When Selecting Bearings
When choosing bearings or bushings for hydraulic cylinders, consider:
-
Load capacity
-
Operating temperature (-200°C to +250°C for self-lubricating types)
-
Speed of operation
-
Environmental exposure
Self-lubricating models are ideal for maintenance-free operations, while lubricated variants may perform better in high-vibration scenarios.
