Description
Product Overview
The VCN312 Stainless Steel Ball Bearing Rollers are precision-engineered motion control components, designed to deliver smooth, low-friction linear and omni-directional movement for heavy-load industrial applications. Featuring a robust threaded stainless steel body, precision-hardened SUS440C main and sub balls, and an adjustable threaded rod design, these ball transfer rollers enable precise height and angle tuning, making them the ideal motion solution for material handling system integrators, packaging equipment manufacturers, and industrial automation builders requiring reliable, adjustable load support.
Key Features & Industrial Performance Advantages
High-Hardness SUS440C Ball Construction for Extreme Durability
The core load-bearing components of the VCN312 threaded rod ball transfer units use precision-polished G10 grade SUS440C stainless steel balls, heat-treated to a hardness of HRC 58-62. This delivers exceptional wear resistance, minimal rolling friction, and long service life, even under continuous cyclic operation in high-volume industrial settings.
Adjustable Threaded Rod Design for Precision Alignment
The integrated metric threaded rod enables micro height adjustments within a ±0.5mm range, allowing perfect alignment of rollers across conveyor systems and machinery frames. This eliminates misalignment issues, reduces uneven wear, and ensures consistent load distribution across all installed units.
Corrosion-Resistant Body & High Load Capacity for Harsh Operations
The roller body is manufactured from high-grade stainless steel, delivering excellent rust and chemical corrosion resistance. Engineered for heavy-load performance, the VCN312 heavy load ball bearing rollers deliver a maximum static load capacity of 800N and dynamic load capacity of 412N, providing reliable support for heavy workpieces and equipment.
