We specialize in manufacturing custom 3168 cylindrical roller caterpillar bearings with reinforced roller designs and heavy-duty construction for excavators, bulldozers, and mining equipment, offering superior load capacity and extended service life in extreme operating conditions.
We produce heavy-duty bearings with precision-ground rollers and reinforced cages designed specifically for crawler equipment, offering superior radial load capacity, impact resistance, and extended service life in demanding construction and mining applications - available with customized dimensions, special heat treatments, and sealing solutions to match exact OEM requirements.
Features of 3168 cylindrical roller caterpillar bearing
The 3168 cylindrical roller caterpillar bearing is specifically engineered for demanding crawler equipment applications, combining rugged construction with precision performance. This heavy-duty bearing features oversized rollers and reinforced cages to handle extreme radial loads and shock impacts in tough operating environments.
Our advantages
As a leading manufacturer of 3168 cylindrical roller caterpillar bearings, we offer superior advantages including precision-engineered oversized rollers for extreme load capacity, specialized heat treatments for extended service life, and fully customizable sealing/lubrication solutions - all produced with ISO 9001 certified processes, advanced CNC grinding technology, and 30% longer operational life compared to standard bearings, backed by engineering support and competitive OEM pricing for crawler equipment applications.
Exceptional Radial Load Capacity: Precision-engineered oversized rollers and optimized internal geometry deliver superior load-bearing performance in heavy-duty undercarriage applications.
Robust Construction: Reinforced cage design and hardened steel components ensure durability under extreme shock loads and harsh operating conditions.
Enhanced Operational Stability: Tight roller spacing and precision-ground raceways minimize deflection for consistent performance under continuous heavy loads.
Contamination Resistance: Advanced sealing options protect against dirt, debris, and moisture in demanding environments like mining and construction.
Space-Optimized Design: Compact yet heavy-duty construction maximizes performance in confined undercarriage spaces without compromising strength.
Customizable Solutions: Available with special coatings (tungsten carbide), heat treatments, and lubrication options for specific application requirements.
Pipeline Layers – Handles combined loads in heavy pipe-laying machine track frames.
Forestry Equipment – Resists impact loads in harvester and forwarder crawler systems.
Military Vehicles – Special hardened versions for armored vehicle track systems.
Offshore Crawlers – Corrosion-resistant models for beach landing equipment and dredgers.
