Product Details

This bearing is built on a continuous wound fiberglass structure encapsulated in high-temperature epoxy, with a self-lubricating PTFE sliding layer that helps keep motion smooth without frequent grease service. The construction is designed to carry radial and axial loads, resist shock and misalignment, and hold dimensional stability in demanding duty cycles. It suits precision-machined bushings and custom shapes where wear control and dry operation matter most.

Product Advantages

Dry-Run Stability

The PTFE-based self-lubricating surface supports smooth motion without relying on continuous grease supply.

Strong Load Support

The wound fiberglass and epoxy backbone gives the bearing the strength needed for heavy radial and axial service.

Tight Fit Retention

The structure is built for dimensional stability and very low water absorption, which helps preserve clearances in harsh environments.

Product Applications

Hydraulic cylinder pivots in boom lifts, scissor lifts, and front-end loaders

used at pivot points where shock load, side load, and repeated movement are common.
King pin bearings and steering linkages in off-highway equipment

suitable for joints that need stable motion and long wear life under impact loading.
Water turbines and valve actuator linkages

a good fit for hydropower and process systems that benefit from grease-free, low-wear operation.
