Construction machinery
Our self-lubricating bearings are given on the chassis of the walking mechanism, body elements and hydraulic components. Includes bimetallic lubrication of rolling bearings, self-lubricating metal-based bearings and self-lubricating plastic rolling bearings.
These bearings have material under high load, excellent wear resistance and anti-dust effect, and the technology of self-lubricating bearings allows much longer maintenance cycles, improves the use of equipment, reduces maintenance costs.
TOP BEARINGS offers a comprehensive selection of sleeve bushing to meet the world’s most demanding surface engineering needs.
We manufacture metal-polymer, engineered ptfe bushing, fiber reinforced composite stainless steel 316 or 304 bushing, metal and bimetal bearings and polymer coatings along with a range of supporting assemblies, bushing blocks and thrust plates.
