4.058 Heavy Duty Combined Roller Bearing for Forklift
The 4.058 Combined Roller Bearing is a heavy-duty bearing solution engineered for forklifts, stackers, cranes, and large material handling equipment.
Designed to withstand high radial and axial loads, it offers excellent stability, long service life, and reliable performance in demanding industrial environments.
This bearing features an eccentric adjustable combined roller structure, allowing precise axial adjustment during installation to compensate for assembly tolerances and ensure optimal load distribution.
High Load Capacity
Designed to support both radial and axial forces, suitable for heavy lifting and continuous operation
Eccentric Adjustable Design
Axial clearance can be adjusted by rotating the eccentric outer hexagon or eccentric ring, improving alignment and reducing wear
Compact Combined Structure
Integrates multiple load-bearing functions while minimizing installation space
High Interchangeability of Components
Standardized accessories simplify maintenance and reduce long-term operating costs
Industrial-Grade Durability
Engineered for forklifts and heavy material handling systems operating under shock loads and frequent cycles
The combined roller bearing consists of:
Two main rollers
One side roller
A shaft head assembly
The rollers are arranged in different load directions, allowing the bearing to simultaneously withstand radial and axial loads.
This design not only improves load efficiency but also reduces overall system complexity and manufacturing cost.
The adjustable combined roller bearing allows precise axial positioning by:
Rotating the eccentric outer hexagon or eccentric ring
Adjusting the axial position of the mandrel
Achieving accurate side roller alignment
This mechanism is especially valuable in forklift and crane applications where installation tolerances and frame deformation are common.
The 4.058 combined roller bearing is widely used in:
Forklifts
Stackers
Container front forks
Cranes and hoisting equipment
Metallurgical industry machinery
Heavy-duty material lifting and transport systems
