Stud-Type Track Roller Bearing (Integrated Bolt Shaft, Sealed) for Heavy-Duty Guide Mechanisms

Stud-Type Track Roller Bearing (Integrated Bolt Shaft, Sealed) for Heavy-Duty Guide Mechanisms

This GQZ stud-type track roller bearing is a high-reliability heavy-duty guide component, featuring an integrated structure of high-strength bolt shaft + sealed roller body (visible in the product image). The bolt shaft (made of 40Cr high-strength carbon steel, hardness 45-50 HRC) enables direct installation without additional shaft parts, while the roller body (premium GCr15 bearing steel, hardness 58-62 HRC) adopts a precision-ground raceway and built-in double-sided rubber seal (2RS)—effectively isolating dust, moisture and contaminants, and realizing maintenance-free operation under regular working conditions. The curved roller profile (matching U-groove guide rails) ensures stable contact with rails, balancing load distribution and reducing wear.
