Specifications

Product Overview

Our High Performance Sintered Self-lubricating Bearings are manufactured using advanced powder sintering technology, designed for high-speed, high-load, and high-temperature applications. With built-in self-lubricating properties, these bearings operate efficiently without additional lubricating oil, offering low friction, long service life, and high thermal stability. Ideal for industrial machinery, automotive, aerospace, and high-temperature equipment.

Key Features

Excellent compressive strength, wear resistance, and shock resistance

Oil-free operation – minimizes risk of stuck or seized components

High thermal stability for long-term use in high-temperature environments

Suitable for radioactive, corrosive, and dusty conditions

Low wear rate for extended service life

Ideal for reciprocating, rotating, and oscillating movements

Handles high static and dynamic loads reliably

Applications

Industrial machinery and equipment bearings

Automotive transmission and engine components

Aerospace high-temperature bearings

High-load and high-frequency reciprocating or rotating parts

Materials Structure

These bearings are made of high-performance Fe–Cu sintered alloy, embedded with dry solid lubricants like graphite and molybdenum disulfide. During operation, the lubricants form a low-shear-strength transfer film on the bearing surface, reducing friction and extending bearing life.

High load and temperature resistance – suitable for both high-speed and low-speed applications

Self-lubricating design – eliminates the need for additional lubricating oil, reducing maintenance costs.

Enhanced bearing capacity – Fe–Cu alloy ensures superior static and dynamic load performance.
