Custom SG Series Track Roller Bearings Manufacturers, Factory

SG Series

SG series orbital roller bearing is a high-performance bearing product specially designed for track and guide systems. They use advanced manufacturing processes and high-quality materials to ensure stability and durability in extreme conditions. This bearing has excellent load-carrying capacity and wear resistance and is suitable for heavy-duty and high-speed applications such as railways, construction machinery and conveying equipment. Design features of the SG series include optimized rolling element and inner and outer ring shapes to reduce friction and improve efficiency. In addition, these bearings also perform well in terms of sealing and dust resistance, effectively extending their service life. Whether in harsh environments or complex operating conditions, SG series orbital roller bearings can provide reliable performance and ensure the safe operation of equipment.

SG Series Track Roller Bearings – High-load, long-life industrial solutions

SG Series Track Roller Bearings are heavy-duty roller bearings designed for harsh industrial environments, suitable for high impact loads, continuous operation and extreme temperature conditions. Made of high-quality steel and precision manufacturing processes, they ensure low friction, high rigidity and ultra-long service life, making them ideal for construction machinery, automation equipment and rail systems.

Excellent durability
Made of vacuum degassed bearing steel (SUJ2), with a hardness of HRC 60-64, the wear resistance is increased by 50%.
Surface phosphating treatment, rust-proof performance meets ISO standards, suitable for harsh environments such as humidity and dust.

High load capacity
Dynamic load rating (C) reaches XX kN, static load (C0) reaches XX kN (fill in according to actual data), supporting radial and axial combined forces.
Strengthened outer ring design, impact resistance is 30% better than similar products.

Low maintenance design
Pre-lubricated seal structure (optional LLB seal or metal dust cover), grease life up to 10,000 hours.
Modular design supports quick replacement and reduces downtime.

Precise operation
Tolerance grade up to ISO P6, operating vibration value is lower than the industry standard, suitable for high-precision guide rail system.
