An Overview of Bowman Oilless® Bearings
Bowman Oilless® Bearings provide a reliable, maintenance-free solution for high-load, low-speed applications where traditional lubrication is impractical.
Our oilless bearings are graphite loaded and can withstand temperatures of up to 400°C (800F) as well as cryogenic temperatures down to -200°C (-400°F) depending on which material is selected. The lubricant used in these bearings is formed from abrasion resistant materials (such as graphite, PTFE etc) and has a stabilised molecular structure – making them suitable for dry environments.
The Key Strengths of the Bowman Oilless® Bearings
Stable Molecular Structure
Engineered with a robust molecular design, ensuring strength, stability, and resistance to deformation.
High Load Capacity
Designed to support substantial loads, providing reliable performance under heavy pressure.
Long-Lasting Lubrication
Incorporates solid lubricants for continuous, self-lubricating performance over extended periods.
Minimal Maintenance
Requires infrequent servicing, reducing downtime and operational costs.
Low Friction Operation
Delivers smooth, efficient motion with reduced energy loss and wear.
Suitable for Low-Speed Uses
Ideal for slow-moving applications requiring consistent, reliable performance.
