Boundary Lubricated Bearing

Definition

The boundary lubricated bearing is a bearing that works by an extremely thin lubricating film between the bearing and the shaft. The film is formed by the adsorption of lubricant molecules, which can separate the metal surface. Under unsatisfactory working conditions, it can also reduce friction and wear to ensure the mechanical operation. It is used in many fields such as automobiles and machinery.

Core advantage:

Innovative lubrication technology: PTFE/ graphite composite lubrication layer (thickness 0.2-0.5mm) achieves a stable friction coefficient of μ≤0.12

Lean oil adaptability: continuous operation under incomplete oil film conditions (3-5 times longer lubrication interval)

Anti-bite design: Unique surface micro-texture oil storage structure to prevent shaft damage caused by dry friction

Environmental protection and energy saving: reduce lubricant consumption by more than 60%

Stats

Typical application scenarios:

Construction machinery: excavator crawler support wheel, crane slewing support

Agricultural equipment: drive shaft of harvester, tractor suspension joint

Industrial transmission: low speed and heavy duty gear box, reciprocating mechanism guide sleeve

Special environment: mining machinery, dust operation equipment and other difficult to maintain occasions

Customer value:

40% reduction in maintenance costs - significantly longer lubrication cycles

2-3 times longer service life - compared to traditional copper sleeves

Emergency condition support - Provides 72 hours of emergency operation in case of unexpected oil outage

Special note:

Customized laser identification for bulk orders (corporate LOGO/ part number)
