Description

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.

Applicable Industries

FAQ

Q: What is the difference between U-groove and V-groove in this series?

A: U-groove is suitable for flat-bottomed guide rails, while V-groove matches V-shaped guide rails—both can be customized according to the equipment's guide rail structure.

Q: Can these bearings be used in high-speed scenarios?

A: They are designed for light-load, low-to-medium speed scenarios (limit speed: ~8000 r/min under grease lubrication), not recommended for high-speed rotating equipment.

Q: Is the lubrication of these bearings maintenance-free?

A: Yes, they are pre-filled with lithium-based grease and sealed with ZZ, so no additional lubrication is needed during their service life (under normal light-load conditions).
